Showers and heavy thunderstorms will spread eastward along the southern Atlantic Seaboard on Thursday, raising the risk of flash flooding and localized damage.

Twelve people were evacuated from a school in Coffeeville, Alabama, on Wednesday due to flooding. The school is at the corner of Highway 84 and Miller Howze road.

There were also reports of water rescues in Thomasville, Alabama near Limestone Circle.

In the Florida Panhandle, severe thunderstorms rumbled through late Wednesday, knocking down trees and power lines in some of the same areas that were affected by Hurricane Michael last October.

Rain is forecast to advance eastward into Thursday. A general 1 to 1.50 inches of rain is forecast with local amounts between 2 and 3 inches.

During Thursday, the rain will focus from the eastern Carolinas to the Florida Peninsula.

Since much of this rain may fall in 12 hours or less, there is the potential for street, highway and other urban-style flooding.

Areas of fog and breezy conditions are also in store with the storm.

The combination of rain, fog and a breeze can make for poor travel on the roads and lead to airline delays.

A few locally severe thunderstorms may develop across the Florida Peninsula and eastern North Carolina on Thursday. The main risks from the storm will be for flash flooding and brief gusty winds. However, a brief spin-up tornado cannot be ruled out.

In the immediate wake of the storm, cooler air will spread to the Southeast for Thursday and Friday.

As the cold air catches up with the back edge of the rain, there can be a brief period of wet snowflakes and ice pellets across the lower Mississippi and Tennessee valleys into Wednesday night.

More persistent snow showers can leave minor accumulations in the North Carolina mountains into Thursday morning.

"Even where no wintry weather makes an appearance, any lingering puddles can turn icy over these regions on Wednesday night as temperatures plummet below freezing," according to AccuWeather Senior Meteorologist Kristina Pydynowski.

Cold into Sat 1.24 AM

However, another batch of Arctic air will follow from Thursday to Friday over the South Central states and Friday to Saturday over the southeastern corner.

Temperatures are likely to plunge 20 degrees after the midweek surge.

Highs within a few degrees of 40 and lows in the 20s are in store for Atlanta on Friday.
