Radar at 4:15 pm CDT continues to show the most widespread storms in SW AL. We had some cloud cover this morning in parts of central and east AL (see satellite picture below from 10:45 am CDT and current temps), which has held temperatures down a bit, in the mid 80s. But, in west Alabama, without clouds, temps soared into the lower 90s. This temperature contrast has set up a thermal boundary, or miniature front, in SW AL. These boundaries create something similar to a sea-breeze flow, helping initiate clouds and storms on the warm side. That may be what’s going on today.
But, the air in the BHM area is still unstable, so additional thunderstorm development is possible.
