Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 220 AM EST Thu Nov 06 2025 Valid 12Z Thu Nov 06 2025 - 12Z Sat Nov 08 2025 ...Unsettled weather for the Pacific Northwest and Northern California, including areas of heavy rain for the coastal ranges and heavy snowfall over the higher elevations of the Cascades through early Friday... ...Some potential for severe weather will exist on Friday across portions of the Ohio and Tennessee Valleys on down to the central Gulf Coast... ...Dry conditions will continue across much of the Southwest U.S. through the Southern Plains... ...Much colder temperatures to arrive by late Friday and Saturday across the Upper Midwest... Across the continental U.S. through this Friday, the primary weather features will be a new quick-hitting atmospheric river in the Pacific Northwest and a new set of cold fronts moving through the Midwest/Great Lakes and into Eastern U.S. The unsettled weather across the Pacific Northwest and northern California will bring cooler temperatures and areas of heavy rainfall to the coastal ranges. Locally a few inches of additional rainfall is expected with this latest Pacific moisture surge, and while the rainfall is expected to largely be beneficial, there may be an isolated concern for some flooding. Meanwhile, areas of heavy accumulating snowfall are expected for the higher elevations of the Cascades and especially northern Washington where the high terrain may 12 to 18+ inches through early Friday. Some of this moisture will spill over into the upslope ares of the northern Rockies as the next Pacific front moves through the Intermountain Region, and this will bring some locally heavy snow here as well. High pressure will largely control the weather pattern across much of the Southwest U.S. and out across the southern Plains, resulting in pleasantly warm and dry conditions. Temperatures are expected to be above normal for this time of year. However, by Friday, a strong cold front moving in from Canada will allow for much colder temperatures to surge into portions of the Dakotas, and especially the Upper Midwest which will set the stage for a cold start to the weekend with below normal temperatures. Low pressure associated with the inclement weather across the West will be ejecting out across the northern Plains and Midwest by Saturday and this will set the stage for at least a swath of light snowfall north of the low track. Farther east, in the wake of low pressure exiting the Northeast, and a trailing cold front clearing much of the East Coast, high pressure will allow for cooler temperatures for Thursday with much of the Northeast U.S. in particular seeing temperatures below normal. However, on Friday, a new set of cold fronts will be crossing through the Midwest and moving quickly into the Eastern U.S. Returning moisture ahead of these fronts will set the stage for showers and thunderstorms to impact much of the Ohio and Tennessee Valley region on down to the central Gulf Coast. Rain will also overspread portions of the Great Lakes and the Northeast. There may be some severe weather focused across portions of the Ohio and Tennessee Valleys in particular, and the Storm Prediction Center has depicted a Slight Risk (level 2/5) of severe weather for south-central Kentucky through middle Tennessee where a threat for large hail may materialize. More regionally, there may also be some gusty winds with the stronger thunderstorms before the cold front advances through the area. These aforementioned fronts should arrive along the East Coast by early Saturday. Orrison/Hamrick Graphics available at https://www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
