Modest rain showers is expected for Coastal Washington and more snowfall for the Cascades and Olympics ranges ... In between the two systems, temperatures are expected to remain mil for the end of November with 40s and 50s North that is about 20 - 25 degrees above the standards ... Southern Rockies to the Southeast will also be seeing some mild temperatures up to 20 degrees above standards ... For your Friday's outlook, the system in the Pacific Northwest will proceed quickly eastward into the Plains with very little in the way of precipitation ... Another mild day will be in store for the Dakotas throughout the Central Plains ... For Washington and Oregon, another low pressure Pacific system will proceed into the region with more rainfall and another round of fresh accumulating snow for the mountains ... Elsewhere, only light to scattered rain showers are possible in the Upper Peninsula of Michigan and in the Southeast as the cold frontal boundary expected to stall out over Northern Florida and Southern Georgia ....
