The severe threat will primarily be damaging winds, along with frequent to continuous lightning heavy rainfall / downpours which may cause flooding and hail.
At this time 6:10 AM EDT 7/20/2012 the main feature with this system has entered North Alabama and Georgia moving in a south southeast direction. This Mesoscale Convective System is already responsible for a couple Special Weather Statements being issued at this early hour where the primary threat has been winds of 40 to 50 MPH and pea sized hail in North Alabama and Georgia.
This activity will continue for much of the day and may increase during daytime heating. The area affected is generally the same as yesterday that being, Mississippi, Alabama, Georgia, North and South Carolina and Tennessee during early morning. Whether or not the storms will intensify later depends greatly on how much the area destabilizes and the possible interaction with outflow boundaries being pushed south southeast ahead of the main complex.
Here’s today’s early morning outlook from the Storm Prediction Center highlighting the Slight Risk of Severe Storms area. The next scheduled update from The SPC is expected around 9 AM EDT. At that time I will also post an update if warranted. Click Image to Enlarge
