A cold front coming ashore in the Pacific Northwest will bring wet weather to the region today. Locally heavy rainfall is possible along the western Oregon and Washington coast with onshore flow bringing Pacific moisture inland. Snow levels will begin fairly high and lower through the afternoon as colder air filters in behind the cold front. Moderate to heavy accumulations will be possible across the Northern Cascades. As the storm system moves inland snow levels will lower across the northern Rockies where some light accumulations area possible. Strong southwesterly flow ahead of the front across much of the western U.S. will allow temperature to rise much above normal for Thanksgiving Day. Portions of the Northern Plains could see high temperatures today as much as 30 degrees above normal while much of the western U.S. will see temperature 10 to 20 degrees above normal. The warmth will spread eastward for Friday with much of the central U.S. enjoying high temperatures 10 to 20 degrees above normal. The eastern U.S. will be relatively cool today with temperature slightly below normal. A lingering frontal boundary across Florida will be a focus for heavy rainfall today.
