Outside of a few light showers, the heavy rain and storms North Alabama saw earlier today has come to an end. Additional showers are expected to redevelop overnight but will not be of any severe weather concern. Lows tonight are mild in the upper 50s.
Tuesday looks to be the transition day between systems. Showers and maybe one or two storms will be possible tomorrow morning. The best focus for any activity Tuesday should be just off to our south.
Wednesday still has the potential to bring high impact severe weather to North Alabama. We have some clarity on how the day could evolve Wednesday, but we will not know some specifics until the event is already taking place. Here's a rough timeline of how we expect Wednesday to play out.
-A warm front will move through North Alabama Wednesday morning. Along it, scattered showers and storms will be possible, but the severe threat will be low. How far north into Tennessee this warm front goes will play a huge role in how the rest of the day unfolds. In short, the further north the front goes, the better ingredients we will have for severe weather. Here is a snapshot of future radar at 11 AM Wednesday.
-We should see a brief lull during the late morning-early afternoon.
-By mid to late afternoon, the environment becomes primed for severe weather. Data sources are hinting at some supercells developing in central Alabama and moving into our region Wednesday evening. Should this supercell threat materialize, our tornado risk will be higher. Large hail would also be a concern too. The severe weather window will likely open around 1 - 3 PM Wednesday. Here's future radar noting the supercell potential at 7 PM Wednesday night.
-Later in the evening, a squall line will develop to our west and race eastward. With this line, damaging winds, isolated tornadoes, and heavy rain would all be expected. The line clears our eastern counties after Midnight, ending our severe threat. Here's one last future radar image showing the line racing through North Alabama at 11 PM Wednesday.
While it looks as though the best severe weather potential is just off to our south in central Alabama and Mississippi, everyone in North Alabama could and likely will see some severe weather Wednesday afternoon and evening. All modes of severe weather remain possible. Damaging winds, tornadoes, large hail, and flooding will all be possible throughout the day Wednesday and Wednesday evening.
Thankfully, the pattern turns much quieter and cooler heading into the weekend.
