Despite largely dry weather across the U.S., a pair of weather systems will create a few problematic spots of weather on Wednesday.
One low pressure system will drift to the northeast farther into eastern Canada on Wednesday. However, there will still be plenty of moisture lingering over the Northeast throughout the day.
This will translate to wet snow or a rain/snow mix for most of New York into Vermont, New Hampshire and most of Maine. There could also be some snow showers in central portions of the Appalachians, generally early in the day.
At the same time, a second low pressure will move across the West. Associated with this low pressure, a warm front will attempt to lift across the north-central U.S. ahead of the low, while a cold front slices through the Rockies and Great Basin.
Showers and thunderstorms are possible across the central Plains, mainly in the afternoon and evening. A few stronger thunderstorms also cannot be ruled out. Be on the lookout for damaging winds, large hail and perhaps a brief tornado or two.
Precipitation will become increasingly likely across the Rockies, northern Plains and Great Basin. Most areas will just see rain showers, but wet snow is likely for the northern Rockies. The tallest peaks in Colorado will also likely see snowflakes flying.
Isolated rain showers are a possibility for the Northwest and California, while dry weather prevails for the Desert Southwest and the south-central U.S. It should also be a quiet day in the Southeast and most of the Mid-Atlantic.
The coldest areas on Wednesday will be the northern Rockies as well as the Northeast. Highs will generally be in the 30s and 40s, though the highest elevations could only see temperatures in the 20s. Fifties and 60s will be common across the Northwest, most of the central/southern Rockies and the northern Plains into the Great Lakes, Midwest and Mid-Atlantic. The mercury climbs into the 70s and 80s for most of California, the Great Basin and Desert Southwest into the central/southern Plains, Deep South and Southeast. Nineties will also be scattered throughout some of the Southwest and far southern Plains.
