First warning headlines

· First alarm weather day for tonight and Thursday.

· Heavy rain returns overnight and tomorrow morning.

· Dries out slowly over the weekend.

Overview of first warning

Good afternoon, Peeks of sunshine will help highs climb to around 80 degrees. Closer to sunset our next round of rain starts to arrive. As showers become heavier and more numerous tonight, we have posted a First alarm weather day.

Three elements are working together to cause this abundance of moisture tonight and Thursday. Onshore flow from the Atlantic, as well as Rafael’s moisture from the Gulf, is being carried into the Midlands thanks to an approaching cold front.

These rounds of heavy rain will lead to totals of 2 to 5 inches across parts of the Midlands. The highest rainfall amounts will occur across the CSRA.

On Friday, the front line moved towards the coast. This will reduce our chances of rain, although a stray shower or two cannot be ruled out over the weekend. High temperatures will drop into the low 70s.
