South
The South is a region of contrasts today. Much of the South will start off with fog, particularly near the Gulf Coast and in the Mississippi and Tennessee River Valleys, but that's where the similarities end. East of the Mississippi River, near record warmth will continue for another day. Several record highs were set on Monday were set across the region, and there's the potential for more to occur today. But the unseasonably warm weather is coming to an end as a frontal boundary drops across the region and cools temperatures closer to seasonal averages on Wednesday and Thursday. Rain will also move into the area Thursday and Friday. By Friday and through the weekend, a rebound in temperatures will occur as temperatures climb back into the 60s and 70s. Along the East Coast of Florida, there's a moderate risk of rip currents again from Cocoa Beach southward to Key Largo, and around Florida Bay (including the north side of the Florida Keys). Temperatures across Florida are expected to remain in the 70s through the weekend. West of the Mississippi River, and particularly in West Texas today, changes are on the way that will affect the whole South through the remainder of the week. A developing winter storm over the Four Corners will start to affect West Texas and Western Oklahoma today with the potential for a significant snow and ice event in places like Amarillo and Lubbock, Texas. Winter and ice storm warnings are in effect for parts of the Texas and Oklahoma Panhandles today and tonight. Where temperatures are above freezing, heavy rain is possible across the Red River Valley (the Texas/Oklahoma border) and portions of North Texas. Another shot of cold air is on tap for the Southern Plains over the weekend as a storm system that's forecast to come ashore in the Pacific Northwest tomorrow and Thursday dives southeastward and brings another chance of precipitation towards the weekend as well as cooler temperatures by then.
Midwest
The Midwest is also a region of contrasts today. West of the Mississippi River in the Northern and Central Plains, the day should start off nice with plenty of sunshine and above average temperatures, but clouds will be on the increase as the day progresses. Tonight, wintry precipitation starts up in portions of Kansas and Nebraska and spread north and eastward into South Dakota, Southern Minnesota, and Western Iowa by Wednesday. A winter storm watch has been posted for tonight through Wednesday for much of the Plains states. Where temperatures remain above freezing, heavy rain is possible for Wednesday, including Eastern Kansas and Western Missouri. East of the Mississippi River, a beautiful December day is on tap with above average temperatures again for today. Rain chances will increase on Wednesday near the Mississippi River and spread across the region towards the Great Lakes on Thursday and Friday. Snow will be possible over portions of Wisconsin and Michigan on Friday and Saturday. Temperatures are expected to remain above average through the remainder of the work week and through the weekend.
Northeast
In the Northeast, a dose of December temperatures hits today. After unseasonably warm temperatures over the last several days, and a few record highs on Monday, temperatures will be back to near seasonal averages for today. With the exception of a stray flurry across Upstate New York and Northern New England, it should remain dry across the region. Temperatures are expected to rebound by Friday back above average once again. The next chance of rain comes in on Saturday and into Sunday.
