Line of Storms Splitting Apart, Severe Storms In South Alabama
Showers and thunderstorms are currently over the northwestern part of the state in Lauderdale, Limestone, Colbert, Franklin, Lawrence, Marion and Winston Counties. The rest of the heavy storm activity is located along and west of the I-65 corridor south of I-20.
A Severe Thunderstorm warning is in effect for eastern Lowndes County until 5:00 PM, and for northern Crenshaw and northeastern Butler counties until 4:45 PM.
As expected, these storms have grown in intensity as we have reached and passed the most intense heating of the day. The SPC has actually removed sections of the state from the “Slight Risk” for severe weather for the rest of tonight, but much of southwest Alabama is still included.
Instability values are higher across the southern half of the state, with some CAPE readings in the 1500-3000 J/kg range. Values are much lower for areas north of the I-20 corridor. Shear values are still relatively low across the state, with much of the higher values still off to the west in Mississippi.
Looks like most of the storm activity will stay below the I-20 corridor with this round of storms, as the former line has broken apart, and the part to the north will be exiting the state to the northeast soon.
Almost the rest of the state is still under a “Marginal Risk” indicating isolated severe storms possible, but limited in duration, coverage, and intensity.
