As indicated in a post early this morning, there is a risk of severe weather later this evening and especially tonight across portions of the Deep South. The latest outlook from the SPC in Norman, OK is shown below. The primary severe weather threat lies within the yellow outlined area:
Moisture is flowing Northward into the region from the Gulf of Mexico this evening, which is resulting in an increase in the instability in the lower levels of the atmosphere. Thunderstorms are forecast to develop along and either side of a stationary frontal boundary this evening and tonight. Thunderstorms will be rather isolated to widely scattered this evening, and will increase in coverage overnight as an upper-level weather disturbance moves in from the West.
The greatest threat with severe storms this evening and tonight will be in the form of large hail and damaging wind gusts, however a few isolated tornadoes also cannot be ruled out.
If you live across this region, make sure that you have a way of being warned of any impending severe weather during the overnight hours. A programmable NOAA Weather Radio is the best bet. There are also services available that will send a warning to your smartphone, some free of charge. I'm working on a post that will feature some of the best smartphone warning apps, but for now a quick Google search should give you some ideas...
The threat of severe weather will not end tonight. Much of the same region (as well as some adjacent areas) will be under a threat of severe weather both Saturday...
...and Sunday (primarily late Sunday and into Sunday night):
Large hail, damaging winds and isolated tornadoes are possible with any severe storms in the above indicated areas over the weekend.
