FIRST ALERT: Expect waves of rain overnight and Friday morning

BIRMINGHAM, Ala. (WBRC) - We can expect period of rain tonight and overnight - especially south of I-20. The visibility at times will decrease to around one mile so use caution when driving late tonight and early tomorrow.

Rain will likely continue south of I-20 through at least noon. Temperatures will reach the mid 50s during the day, but expect a rapid drop through the evening thanks to a clearing sky and north wind. Overnight lows will fall into the lower 30s.

Saturday will be mostly sunny with highs in the mid to upper 50s. We will see rain return to the forecast on Sunday afternoon and evening. Highs Sunday will reach the upper 50s.

A stronger system will impact us on Monday. Right now, we are seeing indications for enough instability and wind shear to result in some stronger thunderstorms. At this point, I can’t rule out severe storms developing during the afternoon and early evening. The risk looks marginal, but not zero. I will know more this weekend as higher resolution data arrives. We will share updates on our WBRC First Alert Weather app.
