More storms move through Saturday
The next wave of scattered showers and storms is moving in from the west this morning. The storms will spread from west to east across the Tennessee Valley through midday, and some of these could be strong to severe again.
The Storm Prediction Center has North Alabama and Southern Tennessee outlined with a *SLIGHT* risk of severe storms for the day ahead. The most likely impacts will come from damaging winds up to 60+mph and large hail. We can’t rule out the threat of a weak tornado at this point, but it is still a low risk.
The stalled front that is helping to initiate the storms this weekend will weaken Saturday and Sunday, leading to lower storm chances each day. On Sunday we’ll see a similar pattern as Saturday, but the storms won’t be as numerous.
Any storms that develop either day could get heavy quickly, with frequent lightning, heavy downpours, and gusty winds. Make sure any plans you make for the weekend will allow you to seek shelter quickly if a strong storms develops. If thunder roars, go indoors!
Still hot, still a few storms next week: Without a cold front to sweep out the humidity or a strong ridge to suppress afternoon storms, each day will have at least a chance of a few spotty downpours next week. Expect highs in the 90s, lows around 70ºF, and a 10-20% chance of some showers or storms.
We are anticipating an upper level ridge to build in the center of the country next week, which will help to suppress much of the thunderstorm activity over north Alabama and southern middle Tennessee. A stray shower cannot be ruled out, but otherwise expect hot and dry conditions Monday through Friday of next week!
