A challenging forecast is now unfolding with the first of several rounds of severe storms today. The storms are surging northeast at between 40 and 50mph. In some cases, these storms are over 50,000ft tall. Storms this morning and through at least 8am will mainly produce heavy rain, gusty winds, and large hail. Expect some pretty good noise makers during the morning hours. The tornado threat with the first round of storms should remain on the lower-end. A severe thunderstorm watch remain in effect areas along and south of I-20 until 9am.
6AM - Noon: Severe storms will continue to develop as warm and unstable air moves northward across the state. These storms will mainly be hail and damaging wind producers. The tornado risk is low, but not zero. The best chance for a tornado to form will be along and south of the warm front after 8am.
Noon - 4pm: Storms will begin impacting West Alabama ahead of the main front. These storms will move west to east across the state. Expect damaging winds and very large hail. It is possible we could see some tornadoes during this time frame.
4pm - 8pm: Severe storms will begin impacting areas east of I-65. This is where some of the strongest and most severe storms could form. Models continue to show the highest tornado parameters in East Alabama extending in Georgia.
Primary Impacts: Very large hail (2-3" size possible), damaging winds over 70mph, and stronger and possibly longer track tornadoes. Greatest tornado potential will be east of I-65 and especially close to the Alabama/Georgia border based on current data. Be prepared for some power outages and good idea to park vehicles in a garage if possible.
