The Storm Prediction Center in Norman, Oklahoma and the National Weather Service in Huntsville, Alabama have expired all watches and warnings for north Alabama.
A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms to occur. For this evening, the main impacts from the severe storms would be damaging wind gusts as high as 60-70 mph.
While we don’t necessarily think of severe weather in the month of June, the reality is that the summer months are prime for “mesoscale convective systems”, which is the scientific term used to describe large thunderstorm complexes that roar through numerous states.
Right now, the Storm Prediction Center has portions of the Tennessee Valley under a *SLIGHT RISK* of severe thunderstorms Friday, with the main impacts being damaging winds.
The caveat is that it’s not 100% guaranteed that we will see severe storms today — it all depends on whether or not the thunderstorm complexes moving through the Midwest this afternoon slide south into the Tennessee Valley this evening. Timing out the storms is dependent on the atmospheric conditions within the storm systems themselves, which can be difficult for short-term forecast models to resolve.
For Saturday, another round of thunderstorm complexes may impact the region. For that reason, the Storm Prediction Center has portions of the Tennessee Valley under a *SLIGHT RISK* of severe thunderstorms Saturday.
These MCS’s or complexes can produce large swaths of damaging winds, and unfortunately, forecast data indicates that a thunderstorm complex may move south from the Midwest into the Tennessee Valley.
Wind gusts as high as 60 mph are possible with these storms, though the wind gusts may be greater if the storms congeal into a line. Check the radar if you are traveling out of town Friday afternoon through early Friday evening.
