While rain has moved out of South Texas it was just getting started in the Southeastern states on New Year's Day.
Enough rain will fall to slow travel and impact outdoor activities from Tallahassee and Jacksonville, Fla., to Savannah, Ga., Charleston, S.C., and Wilmington, N.C.
The bulk of the rain will fall from northern Florida to the coastal areas of the Carolinas, where a general 1 to 2 inches of rain is forecast with local amounts near 3 inches.
In a few cases, from the northeastern Gulf Coast to the southern part of the Atlantic Seaboard, the rain can lead to poor-drainage-area flooding. Much less rain is forecast to fall on the southern Appalachians and foothills that were soaked by the storm last weekend, so few new flooding problems are anticipated on streams and rivers.
A few showers will affect central Florida with very little rainfall likely in South Florida.
The moisture will sweep into a large and developing storm system in the Northeast that will unload heavy snow and produce blizzard conditions in some areas Thursday night into Friday.
As that storm strengthens and moves away Thursday night and Friday, gusty northwesterly winds will draw down colder air from the Midwest and Northeast. The winds in the region can lead to flight delays at area airports, including Atlanta and Charlotte, N.C. Meanwhile, the storm in the Northeast may also tie up aircraft and crews.
Temperatures will plunge from the 50s Thursday to the 20s Thursday night over much of the South. In most cases roads will dry off in Mississippi, Alabama, Georgia and the Carolinas. However, there could be a few icy spots developing.
Warmer air will return this weekend, ahead of another storm system that will bring a quick change back to cold during early next week.
