BIRMINGHAM, Ala. (WBRC) - At the time of this update, most locations were experiencing a much needed break in the rain. However, radar was showing lots of shower activity to the far southwest. This wet weather will be tracking to the northeast and it may hold together, with impacts later tonight; a flash flood watch is in effect until 10 p.m.

An upper level disturbance is responsible for this rainy and stormy pattern. In fact, you can see this system spinning across Mississippi and Alabama on the regional satellite and radar. The disturbance will keep things very unsettled on Wednesday. Plan for the possibility of wet roads and low visibilities in the morning. Isolated showers and storms will be possible during the morning hours, in addition to patchy dense fog.

We will have periods of rain free weather during the day, with highs in the middle 80s. The chance for scattered storms will continue in the afternoon. The main concern will be localized flooding. Parts of our area have received over 20″ of rain since June 1.

THE REST OF THE WEEK: Rain chances will remain in our forecast for the rest of the workweek and weekend. However, the timing for the rain will become more limited to the afternoon and evening. A more typical July setup will return, with highs nearing 90º, and heat activated pop-up storms after lunchtime. The setup for next week will feature even lower rain chances by Monday, with the possibility of highs in the middle 90s.
