MONDAY, JANUARY 15TH, 2018 Assistant Forecaster / Social Media Coordinator David L Saurer SEVERE WEATHER OUTLOOK: Today's Severe Weather threat will be NULL across the entire lower 48 as well as NO THUNDERSTORMS in the forecast anywhere across the Nation as well ... NATIONAL FORECAST: Today's outlook has a cold frontal boundary expecting to dip southward for today's forecast, reaching Central Texas by this evening, and the Western Gulf Coast by Tuesday AM .. Gusty northerly winds are expected and will begin to usher in the arctic air in the wake of the frontal boundary with max temps to be roughly 15 to as much as 35 degrees below mid January standards across the Central and Northern Plains for the highs today ... Given the facts this is the coldest time of the year, this translates to highs below zero for the majority of the Dakotas with well below freezing for highs across areas as far south as the Northern Texas Panhandle into Northern Arkansas for today's highs ... Bundle Up indeed! As this cold frontal boundary continues southward through Texas tonight, it is expected to encounter a surge of northward flowing Gulf of Mexico moisture, this will allow for some wintry mix of precipitation extending across Central Texas, across the ArkLaTex and into the Lower Mississippi Valley .. Snowfall should be the main precipitation type from far Northeastern Texas into and across the Mississippi River Valley, but sleet and freezing rain are expected for Central and Southern Texas starting this evening and lasting through early Tuesday PM ... Minor accumulations (1-2.5", with locally up to 3") could cause significant travel delays given these portions of the Southern states are not accustomed to handling icy conditions ... The modified arctic air is expecting to proceed into the South and Eastern portion of the Nation through Wednesday, weakening some in its potency as it reaches the Eastern Seaboard ... However, temperatures will be forecast to be cold enough to support some snowfall potential across the Central Appalachians into the Northern Mid-Atlantic region with accumulations possible by late on Wednesday AM .. A coastal low pressure storm system is expected to organize off the New England Coastal areas during the course of the day on Wednesday which could very well bring some moderate snowfall accumlations into the New England region for mid week ... Finally, temperatures will begin a moderating trend for the Northern Plains by the middle of the upcoming week ahead while temperatures across the Western portions of the Nation remain above mid January standards ... Rainfall associated with a cold frontal boundary will reach the West Coast for tonight, but stay relatively light compared to the previous system as the frontal boundary is expected to dissipate inland ... After a short break, a second and much stronger push of moisture off the Pacific is expected to impact the West Coast by the beginning mid to late on Wednesday ... HAVE A GREAT MONDAY and REMEMBER to REMAIN WEATHER AWARE! Respectfully Yours, Your Lead Forecaster and Lead Weather Analyst, SEMCF and TRAPT David L Saurer

SUNDAY, JANUARY 14TH, 2018 Assistant Forecaster / Social Media Coordinator David L Saurer SEVERE WEATHER OUTLOOK: Today's Severe Weather threat will be NULL across the entire lower 48 as well as NO THUNDERSTORMS in the forecast anywhere across the Nation as well ... NATIONAL FORECAST: Today's outlook has the biggest story through Tuesday being the cold air inflitering and persistent over the Plains into the Midwest .. While the colder air in entrenched, this may only break a handful of records, snow and wintry mix is expected for locations in the South who do not typically see any wintry precipitation ... The strong cold frontal boundary will proceed into the Northern Plains for today's forecast not only to reinforce the Arctic air, but to bring a Clipper system that will bring in some light snow showers with light accumulations, locally higher totals could be expected in the upslope regions of the Central and Northern High Plains through Monday and near the track of the surface low through the Upper Midwest and Upper Mississippi Valley going into the Great Lakes region for Monday Night into Tuesday ... Temperatures are expected to be forecast near normal for today across the Central and Northern Plains, but by Monday, the highs will stay below zero for the majority of the Dakotas into Minnesota and sub-freezing highs will spread and reach as far south as Northern Texas Panhandle into Northern Oklahoma ... These readings will be nearly 35 degrees below mid January standards ... The anomalous cold will continue in the forecast for the South and Eastern portions of the Nation for Tuesday and by the time this frontal boundary reaches the Southern Plains, a rain/snow mix is expected to transition to freezing rain/sleet and eventually some snow showers as the colder air infilter the region into Central Texas .. Light accumulations will also be a possibility for Southern Oklahoma, Arkansas, and Northern Louisiana for Monday night into Tuesday .... Finally, on the agenda, out in the Western regions of the Nation, warm and mainly dry conditions will stay in place until a cold frontal boundary reaches the West Coast by early on Tuesday morning bringing the next round of rainfall from Central California to Oregon and Washington ... This first round of anticipated rainfall is expected to be beneficial given the below average precipitation over the past few weeks for this region, but heavier rainfall will be a possibility for the Pacific Northwest and Central/Northern California by late in the week ahead ...

SATURDAY, JANUARY 13TH, 2018 Assistant Forecaster / Social Media Coordinator David L Saurer SEVERE WEATHER OUTLOOK: Today's Severe Weather threat will be NULL across the entire lower 48 as well as NO THUNDERSTORMS in the forecast anywhere across the Nation as well ... NATIONAL FORECAST: Today's outlook has a very powerful cold frontal boundary continuing to proceed throughout the Northeast for today's forecast, following by some very sharp temperature drops in the wake of the boundary ... 24 hour temperatures swings have been noticed behind the frontal boundary from 20 to as much as 40 degrees from the Great Lakes to the Gulf Coastal region, and these dramatic changes will translate into the Mid-Atlantic and Northeast for today's forecast .. Temperatures are falling already this morning behind the front and will not rise any further during the course of today ... Locally heavy rainfall with FLOOD ALERTS in effect for New England will change this morning to freezing rain and sleet followed by locally heavy snowfall on the back end of the system impacting portions of Northern New York into Northern New England .. The greatest threat for freezing rain ice accumulations is expected from Southern New Hampshire into Eastern Maine with up to a tenth of an inch possible ... The quick-progressive system will bring an end to the majority of the snowfall by early afternoon .... Across the Northern Plains into Kansas and Missouri, high temperatures today are expected to be almost 25 degrees below mid January standards, but warning is expected for Sunday ahead of another cold frontal boundary reinforcing the colder air from Canada ... Expecting near to slightly above average for mid January standards for Sunday anywhere from the central Plains to North Dakota and Montana ... However, another strong cold frontal boundary will bring a likely shot of light snow showers by Monday morning with a surge of colder air bringing the temperatures back to reality, below mid January standards ... In fact, we've seen Monday's forecast highs becoming colder than today's forecast ranging between 15 to as much as 35 degrees below the average ... Finally, noticing some upper-level ridging dominating the pattern across the Western areas of the Nation throughout the weekend allowing for drier conditions with temperatures above mid January standards ... A change in the pattern is anticipated starting on Monday with the arrival of the cold frontal boundary to the West Coast along with rain showers from northern California to the Pacific Northwest ....

FRIDAY, JANUARY 12TH, 2018 Assistant Forecaster / Social Media Coordinator David L Saurer SEVERE WEATHER OUTLOOK: Today's Severe Weather threat will have a few strong to severe storm a possibility across portions of the Coastal Carolina for this evening ... A few storms could contain damaging gusty winds ... A few thunderstorms are a possibility ahead of the frontal boundary moving from the Ohio Valley to the Eastern Seaboard ... This will stretch from Central New England through the Mid-Atlantic and down into the Eastern Gulf Coastal region into the Florida Peninsula ... NATIONAL FORECAST: Today's outlook has a very powerful cold frontal boundary located between the Mississippi River and the Appalachians for this morning, this is expected to proceed on eastward during the course of today's outlook and eventually clear the entire Eastern Seaboard by Saturday PM ... Although, it will be mainly cloudy, today's highs will be in the 50s for the majority of New England to the lower 70s for portions of the Mid-Atlantic states .. The warmer temperatures combined with the rainfall may cause some dangerous flooding conditions over snow covered surfaces and near partially frozen rivers from the Central Appalachians into Central New England ... Be aware of this and report the flooding to the National Weather Service ... A sharp temperature gradient is being monitored in the wake and ahead of the powerful frontal boundary with 24 hour temperatures swings of 20 to as much as 49 degrees expected, greatest concentration will be a cross the Northern locations ... The transition to colder temperatures will be co-located with the rainfall changing to freezing rain, sleet, and eventually snowfall for the majority of the Ohio and Tennessee Valleys into the interior sections of the Mid-Atlantic region and the Northeast today and tonight ... It appear locations along the I-95 corridor along and WEST will likely see some sort of frozen precipitation from this system between Wilmington DE to Boston .. Heaviest concentration of snowfall is expected from northwestern Pennsylvania into far northern New York where upwards of snowfall accumulations to a foot is expected by Saturday AM ... The northern Plains are expecting to see another brutally cold day with high temperatures at or below zero for the majority of today's outlook with the anomalous cold stretching down to the Central Gulf Coastal region ... Forecast high temperatures will be in the 40s for Southern Louisiana for today through the weekend, mainly about 25 degrees BELOW mid January standards ... Finally, light to locally moderate snowfall is in the forecast for the higher terrain from the Washington Cascades into the Central and Northern Rockies tied to a weakening Pacific frontal system and resulting upslope lift through Saturday AM ... Rain showers will stay in the forecast for the Pacific Northwest, but mainly confined to mostly coastal regions of Washington through Saturday with partial clearing expected by the afternoon hours as the upper-level ridging builds over the Western portions of the Nation .... HAVE A GREAT FRIDAY and REMEMBER to REMAIN WEATHER AWARE! Respectfully Yours, Lead Forecaster and Lead Weather Analyst David L Saurer Good Morning ... I would like to apologize, firsthand. I unexpectedly lost my internet services back in December due to financial hardship ..

Isolated to some widely scattered showers and thunderstorms are possible for this afternoon and evening across portions of the Gulf Coastal region through the Mississippi Valley ... We could also see a few isolated thunderstorms across portions of the Carolinas and the Mid-Atlantic with the warm sector and southerly winds ahead of a strong storm system out of the Plains .... Instability will be limited to allow anything severe ... NATIONAL FORECAST: Today's outlook has a very powerful cold frontal boundary with the backend of the frontal boundary having the surge of Arctic air will proceed through eastward from the Plains through the Mississippi Valley for today's outlook .. Late tonight into Friday, this frontal boundary is expected to proceed into the Ohio and Tennessee Valley in addition to the Southeast ... Finally, by Friday evening and overnight through Saturday AM, the cold frontal boundary will approach the Eastern Seaboard and linger into New England for Saturday night ... Precipitation is expected to follow in the wake of the frontal boundary over the next few days -- and with temperatures falling rapidly, wintry mix along with the snowfall will be a strong possibility. For today's forecast, the heaviest mixed precipitation along with the ice will occur along the western edge of the Ohio and Tennessee Valleys with the heaviest snowfall axis in the Upper Midwest / Upper Great Lakes in addition to portions of the Ohio Valley ... Wintry mix will spread the axis into the interior New England and Northeast along with Central portions of the Ohio and Tennessee Valleys for Friday's outlook ... In addition to this, heavy snowfall can be expected along the Lower Great Lakes ... This winter storm system will proceed into New England for Saturday's forecast by having the bulk of the wintry mix and snowfall in the region ... Travel is expected to be very hazardous through the Plains to the Northeast with the icy conditions in the forecast .. Rainfall and embedded thunderstorms are possible in the Southeast to the Mid-Atlantic ahead of the system for the next few days as this frontal system proceeds throughout the regions ... Many winter weather alerts in effect, check with your local National Weather Service pages on social media or website for the details (weather.gov) A Pacific storm system with an associated frontal boundary is approaching the Pacific Northwest for today's forecast -- bringing along an increasing chance for precipitation throughout the region along with the Northern Rockies ... This activity will continue into early Friday morning due to the Pacific onshore flow; however, it is expected to lighten up by tomorrow evening ... Heavy snowfall is expected across the higher elevations of the Washington Cascades and the Northern Rockies ... Some of this precipitation is expected to linger Friday night into Saturday's forecast -- thus lighter amounts of higher elevation snowfall could be expected as well ... By Saturday evening, the conditions are expected to improve with tampering of the precipitation shield. Finally, the last agenda of today's outlook has the very frigid conditions following the wake of the cold frontal boundary with another Arctic invasion ... High temperatures are expected to be below zero throughout the Northern Plains for today's outlook .. and temperatures below freezing across the Central Plains and Upper Midwest ... These temperatures are almost 30 degrees below standards for mid January .. Consequently, WIND CHILL ADVISORIES are in effect for portions of the Northern High Plains and Northern Plains as the wind chill factor are forecast to reach 30 below zero values ... In contrast, areas to the East of the Mississippi Valley will experience temperatures almost 35 degrees above mid January standards ... By Saturday, the majority of areas in the Eastern portions of the Nation will be near or below average, with the exception of the Mid-Atlantic and Coastal New England ....

Today's Severe Weather threat is NON EXISTENT for the Lower 48 ... NO THUNDERSTORMS are in the forecast for the Lower 48 ... NATIONAL FORECAST: Today's outlook has warm and dry conditions dominating the Western half of the Nation and will persist for the remainder of the week ahead with varying threats in the wildfire conditions ongoing across Southern California ... While current winds have weakened some compared to last week's readings, very low relative humidities values will continue to impact the region bringing ELEVATED FIRE DANGER CONDITIONS ... An upper-level disturbance expecting to proceed southward on Thursday will allow for a re-strengthening of the high pressure out in the West and that will bring the gusty Santa Ana Winds back into place along with the low relative humidities levels, that will increase the fire risk to DANGEROUS LEVELS on Thursday across Southern California .... The departure of the coastal low that impacted New England overnight and this morning with a wintry mix, cold and breezy conditions will be left in its wake, especially across the Northeast where highs are expected to struggle to get out of the teens and 20s for locations inland ... In fact, the majority of the Eastern Seaboard will see temperatures of 10 to 15 degrees below normal for Mid December standards, with near 20 degrees below normal across portions of the interior Northeast ... Lake effect snowfall will continue in the downwinds of the Great lakes through Friday, but there will be enough shifting of the wind direction to prevent the majority in the way of heavy snowfall ... A quick-proceeding clipper system is expected to proceed through the Central Great Lakes region for today's forecast bringing accumulating snowfall to portions of Lower Michigan into portions of Ohio and Pennsylvania .. Anywhere from 3 - 6" with locally higher amounts possible and expected in these locations through Thursday AM ... Finally, a weak system is expected to proceed across the Central Plains during the course of the day on Thursday to bring light snow showers, possibly mixing with some rain, but any snow accumlations are expected to be very light for now ...

Today's Severe Weather threat is NON EXISTENT for the Lower 48 ... NO THUNDERSTORMS are in the forecast for the Lower 48 ... NATIONAL FORECAST: Today's outlook has a strong ridge of high pressure over the Western portions of the Nation that is expected to gradually weaken and help out with the wildfire situation in Southern California, but will be keeping the warm temperatures in place ... Gusty winds and low relative humidities will continue to pose an ELEVATED FIRE DANGER today, and will diminish in threat for Wednesday .... An area of low pressure is organizing and strengthening over the Lower Great Lakes for today's forecast, dragging a reinforcing cold frontal boundary across the Eastern Seaboard ... Much colder temperatures are expected to filter in behind the frontal boundary for the Eastern portions of the Nation for tonight through Wednesday with highs almost 25 degrees below mid December standards from Florida to the Great Lakes ... Meanwhile, as the low pressure storm center continues to wrap up for tonight into Wednesday morning over New England, moderate snowfall is in the forecast for portions of Upstate New York into the interior New England with a wintry mix expected possible in central Massachusetts to the coastal regions of Maine ... WINTER STORM WARNINGS and WINTER WEATHER ADVISORIES are in effect for these locations through Wednesday AM given the anticipation of deteriorating conditions .... Colder air filtering in behind the strong cold frontal boundary across the Great Lakes will continue to produce lake enhancement snow showers with the greatest snowfall accumulations through Thursday across Southwestern Lower Michigan and east of Lake Eries and Ontario where local totals will be over a foot in some spots ... Finally, the north-central portions of the Nation and the Upper Mississippi Valley is expected to see a series of weak clipper systems proceeding the region for tonight and Wednesday PM ... In advance of the first clipper, downslope winds will generate high temperatures across the Central and Northern High Plains in the 50s and 60s, well above average for mid December standards ... Colder temperatures will reside farther North and East in this pattern with the clipper systems generating light snow showers or a wintry mix across the Eastern Dakotas into Minnesota, but any accumulations are expected to be generally an inch or less ...

NATIONAL FORECAST: Today's outlook has a good ridge of high pressure beginning to finally weaken this week as the upper-level pattern is undergoing a transition ... However, dry conditions with above normal temperatures will continue across a majority of the Western / Southwestern portions of the Nation into the Central Great Plains ... Strong, gusty Santa Ana winds continues in Southern California and while winds are gusting, they are expected to finally weaken by midweek, ELEVATED FIRE DANGERS continues for another couple days in Southern California as well ... A clipper system is proceeding to track from the Upper Mississippi Valley into the Great Lakes for today and tonight's forecast bringing some light snow showers and a renewed surge of colder air ... High temperatures for the forecast on Tuesday are only to be in the teens in Wisconsin and lower Michigan which is almost 20 degrees below average for mid December ... In addition, northwesterly winds in the wake of the clipper system will set up for heavy lake enhanced snowfall for the downwinds of Lakes Superior and Michigan ... Finally, as the storm system proceed into the Northeast on Tuesday, light to moderate snowfall will overspread upstate New York into the interior portions of New England for the early afternoon ... The surface low is expected to strengthen into Tuesday PM as it proceeds to track through Maine ...

NATIONAL FORECAST: Today's outlook relatively quiet weather for the majority of the Nation as a winter storm system is finally proceeding away from the Northeast, this morning ... A quick proceeding and moisture starved upper-level disturbance is bringing an opportunity for a few light snow showers to the Northeast for today and tonight's forecast, but the greatest snowfall accumulations will be EAST of Lakes Erie and Ontario due to lake enhancement where local accumulations up to a FOOT in the forecast through Monday ... Be on Alert! Heavy lake enhanced snowfall will also be a possibility across the Upper Peninsula of Michigan for Monday Night into Tuesday behind an quick proceeding Alberta Clipper system .. This Clipper system is expected to drop a quick one to as much as three inches , to Northern Minnesota and Wisconsin by Monday afternoon ... Temperatures along the Eastern Seaboard are expected to remain BELOW normal up to 20 degrees below mid December standards with some moderation possible for Monday's forecast ... Majority of the Plains will remain above normal up to 30 degrees through Monday with westerly to northwesterly downslope winds at the surface ... Winds will be gusty at times, especially for Monday after the passage of a cold frontal boundary tied to the aforementioned clipper system ... These winds will generate drier conditions leading to an ELEVATED FIRE RISK extending into Central and Southern High Plains through Monday's forecast ... Be aware of this factor ... Finally, the greater risk of wildfires are continuing across Southern California through, where CRITICAL FIRE WEATHER CONDITIONS continue through at least Monday giving the strong forecast of Santa Ana winds and very low relative humidities ....

As this low finally proceeds farther north, snowfall will taper off, should end by Sunday PM ... Looking ahead to the Upper Midwest and the Great Lakes, we have a series of upper-level disturbances for the next few days ... This is going to be bringing a reinforcing shot of colder air over the Great Lakes and that will result in moderate to locally heavy snowfall in the downwinds of the Great Lakes ... For today's forecast, the heaviest snowfall is expected to occur along the UP of Michigan and the Eastern Shores of Lake Michigan as one disturbance proceed the region ... The lake enhanced snow event will shift to the Lower Great Lakes on Sunday ... By Monday AM, another disturbance will proceed southward over the Upper Midwest ... With the cold shot in place, the precipitation is expected with this system in the form of all snow ... Finally, upper-level ridge continues to be centered over the Western sections of the Nation, this is not good news at all keeping the warm and dry airmass that has been giving Southern California tons of issues battling the horrific wildfires ...
