Showers and thunderstorms are possible Wednesday for portions of Central and Northern Florida. Rain will change to snow across the Mid Atlantic, Northeast, and New England. Light to moderate snow will fall across the Upper Mississippi Valley, Snow continues for the Rockies.

Central into Northern Florida and the Southeast: Low pressure system will continue to develop over the Southeast states into early Wednesday, allowing for continued showers and non-hazardous thunderstorms along with localized flash flooding.

Mid-Atlantic, Interior Northeast and into New England: Low pressure mentioned above will and will track rapidly northeastward into the Mid-Atlantic and eventually the Northeast and New England by Wednesday evening. Precipitation will start as rain for a majority of the region that is not mountainous, but will then change to snow as colder air filters into the area later in the day. As with any system tracking up the East Coast, the track of the low will determine where the heaviest snow accumulations occur and which areas remain mostly rain. Finer details still need to be sorted out, however last evening’s model runs began trending farther west with the track of the low, which would result in some healthy snow totals (locally up to 1 foot) for inland locations. Nevertheless, major travel problems are anticipated over the region on the busiest travel day of the year.

Upper Mississippi Valley: The clipper system will continue to dive southeastward, and will generate light snowfall across the Upper Mississippi Valley on Wednesday. Moisture will still be lacking, therefore major accumulations are not likely and there will be rain mixed with snow at times cutting down accumulations.

Rocky Mountains: Continued snowfall is expected across the region on Wednesday, though amounts will be somewhat lighter than on Tuesday. Higher elevations will likely see another 8 to 12 inches of accumulation, with lower elevations experiencing 4 to 8 inches.
