FIRST ALERT: Flood threat continues overnight, with periods of rain and possible storms

First Alert Weather 9p 2-19-19

BIRMINGHAM, AL (WBRC) - MORE RAIN OVERNIGHT: Rain and the chance of thunderstorms will continue across our area tonight as a warm front slowly lifts north into Alabama. We may see some additional small hail producers tonight but that threat will be more isolated. Rain amounts are already topping the three inch mark in many locations to the north and flooding will be a concern along the 278 corridor. The Cullman County schools will have a two hour delay start time on Wednesday.

The temperature has leveled off in the 40s and we will see a slow rise in temperatures through tomorrow. It’s still going to be very chilly in the morning; however, temperatures will be rising into the 50s and 60s during the day.

FIRST ALERT FOR A MARGINAL SEVERE RISK WEDNESDAY: The warm front will reach our southern counties tomorrow afternoon and there will be enough instability for a marginal severe risk, especially in areas to the southwest. This threat will mainly be between lunchtime and 7 p.m. Highs will range from milder 60s over southwest areas to cooler 50s further northeast.

The threat of flooding will continue to be an issue across the entire area through tomorrow night. I would plan on more rainy periods in the morning and especially during the afternoon and evening. The axis of steadier rain will slowly drift south tomorrow night and then return north again on Thursday. So this will mean more rainy weather, along with the possibility of a thunderstorm.

THE REST OF THE WORK-WEEK AND WEEKEND: The stalled front over the region will lift north on Thursday and this will continue to be a focal point for steadier rain. I’m thinking the axis of heaviest rain may lift far enough north at times on Friday and Saturday, to allow for some breaks in areas along and south of I-20. It’s actually going to feel quite nice as we head into the weekend, with temperatures in the 70s.

STORMS LATE SATURDAY? The colder air will be on the move again by late Saturday so the chance of rain and storms will be on the increase. We will also need to keep an eye out for a threat of stronger storms Saturday afternoon and evening. This system looks to exit our eastern areas by sunrise time on Sunday morning, with highs in the 60s. So we should catch another break in the wet weather. However, this won’t last long because forecast guidance is showing another rainy setup by the middle of next week. Stay weather alert as we continue to monitor this active pattern. A flood watch is in effect for our area until late Thursday. We will be sending out lots of updates on our FREE WBRC First Alert Weather App.
