SEVERE WEATHER OUTLOOK:
Today's severe weather outlook has a shot of a few severe thunderstorms over a portion of Southeast Texas into the lower Mississippi Valley with an upper-level trough cross over the Central Plains with a surface low up in the Dakotas ... These storms for this afternoon and evening hours will be accompanied by LOCALLY DAMAGING WINDS and possible ISOLATED LARGE HAIL .. The Storm Prediction Center has issued a MARGINAL RISK for this highlighted region, please stay on alert and listen closely to updates on this forecast ... NATIONAL FORECAST: Today's outlook has a storm system with low pressure across the Northern Plains and Upper Midest bringing some widespread snow and strong winds as this upper-level trough and surface cold frontal boundary proceeds eastward through the Central portions of the Nation ... BLIZZARD CONDITIONS are expected from Southwestern North Dakota down across the majority of Central South Dakota and far Northern Nebraska gibven the expected high winds ... 1'+ is expected in the forecast, locally with this winter storm going through Tuesday before the system then begins to proceed towards the Eastern portions of the Nation ... Numerous BLIZZARD WARNINGS and WINTER STORM WARNING, along with WINTER WEATHER ADVISORIES and HIGH WIND WARNINGS are in effect from eastern Montana southward to Kansas and east to Wisconsin and northern Illinois .. The snowfall will spread to the Great Lakes, northern Ohio Valley and Northeast by midweek as the frontal boundary proceeds towards the Eastern Seaboard ... Along the trailing cold frontal boundary, scattered to widespread showers and thunderstorms will develop in the warm sector over the Central/Southern Plains to the Midwest as southerly flow from the Gulf of Mexico transports moisture on northward .. The swath of precipitation will spread on eastward into the Ohio and Tennessee Valleys and including the Gulf Coast and into portions of the Mid-Atlantic region .. Some locally heavy rainfall will occur, but right now the amounts DO NOT appear to be heavy enough to support much in the way of a flooding threat .. We will keep you posted! Gusty winds ahead of a cold frontal boundary and also behind it coupled with low relative humidities will maintain the threat for DANGEROUS FIRE WEATHER conditions .. The fire weather threat should tend to subside by Tuesday through as the winds begins to diminish .. Across the Western areas of the Nation, temperatures will start off cool, but with high pressure building in across the Intermountain West, some gradual moderation can be expected ... HAVE A GREAT MONDAY and REMEMBER to REMAIN WEATHER AWARE! Respectfully Yours, SEMCF/TRAPT Lead Forecaster and Lead Weather Analyst David L Saurer
