A strengthening mid and upper level trough currently over Texas and Oklahoma will shift eastward into Mississippi and Alabama by this afternoon with a cold front surging east from Louisiana and Mississippi.    This storm will deepen and move north-northeastward across Alabama and Georgia.  Dewpoints ahead of this cold front are already in the 65 to 70 degree range with very buoyant air present.  The net result of these factors will be the potential for a significant tornado outbreak today.

Severe Weather is currently taking place across parts of Alabama, Georgia and Florida and a Tornado Watch is in effect until 10 AM EST.  Cluster of severe storms remain from the overnight hours and the storm environment remains favorable for supercell development.  A few tornadoes are likely and they could be intense.  Damaging winds and Large hail are also possible with these storms.

Additional watches should be expected during the day today.

While the current storms across Georgia are present, the main risk does not occur until later this morning, when thunderstorm activity will begin again over Southern Alabama and the Florida panhandle.  These storms will the spread east-northeast across Florida and Georgia through the day.  Long tracked, strong tornadoes will be possible in fast moving supercells, in addition to damaging winds and large to very large hail.  The severe risk will spread northeastward into the Carolinas this evening as the system moves toward the Southern Appalachians.  Tornadic supercells could continue to occur in south Carolina and Southern North Carolina during the overnight hours.

Further South, the cold front will reach the remainder of Florida later this evening and overnight and bring the risk of severe thunderstorms and a few tornadoes.

Any and all preparations for this event should be concluded by early this afternoon.   This will be a very dangerous situation for many people.   Please be prepared and ready at a moments notice.   We here at Firsthand Weather will do our best to be with you every step of the way this afternoon but keep your weather radios handy and pay attention to your local news broadcasts for updates on warnings that occur.    Facebook likes to prevent you from seeing our page if we post a lot of posts, as we likely will this afternoon.   To see what we are writing, you will need to go directly to our facebook pages and website, please do not count on your newsfeed to give you our information.
