A cold front will move slowly through Alabama on Sunday. Ahead of the front, a moderately unstable airmass will be in place, setting the stage for strong thunderstorms.
CAPE values will be in the 1,000 to 2,000 j/kg range, and possibly higher. Lifted indices will push -7.
This will provide fuel for strong storms. The front will be the spark.
Damaging winds will be a real threat. Lightning and torrential rains will also be a problem.
So, we want everyone to pay careful attention to the latest weather information Sunday afternoon and into the evening hours.
NOTE FROM THE TROPICS
Arthur is still a tropical storm tonight despite being inland over the Yucatan Peninsula. It is moving westward and should stay inland or hug the coastline of the southwestern Gulf as it does. It should be a depression by morning and stay there until it dissipates in about three days. The Gulf will be nervous over the next two weeks with the possibility of further development later in the week ahead.
