Severe Thunderstorm Watch Until 3 AM



So I totally missed the earlier round of severe thunderstorms, but see that it produced some wind damage and several large hail reports (including golfball-sized) around North Alabama. Probably will not stay up to post updates on this tonight much. But figured I'd post the watch. Long-term I think I'll just use this to practice forecasting and leave the radar and watch/warning map up on the main site. The real-time updates take more energy and time than I have anymore, for a total volunteer effort. 


Here is a preliminary look at the storm reports from earlier this afternoon. All the tornado reports appear to be from Indiana, which was what was expected, that general vicinity, and then down here, a lot of straight-line wind damage reports in thunderstorms. And it looks like the hail overperformed for several places, making it up to golfball size. 

This watch for tonight does mention that wind gusts up to 70 mph are likely. 

If you get a Severe Thunderstorm Warning from your NOAA Weather Radio tonight, best place to get is a small interior room or hallway on the lowest floor of a sturdy house. But at minimum, stay inside away from windows or anything that easily conducts electricity. If you've got trees around, take that into account. If one fell in the wind, what would the safest place be in your home . . . that's the sort of thing you have to consider. 

After tonight, no organized storms for a while, just going to have a lot of heat and a chance for very scattered storms, heat will really ramp up on Thursday and Friday beyond whatever we get by Wednesday. 




9:12 PM - Guess I can do a few updates. The NWS Birmingham is emphasizing that these storms moving into Marion and Lamar Counties are dangerous and have been doing widespread wind damage in Mississippi. There was an earlier warning for Muscle Shoals and places up that way, but it has been let go since the storms weakened below severe limits. The air appears to be more unstable a little further south, Marion and Lamar Counties. 




10:04 PM - Good news as of right now, the storms appear to be weakening, no warnings currently in effect. 




10:06 - And the National Weather Service offices are starting to cancel this watch out already. It does remain in effect for Cullman County. Also for Blount, Walker, Winston, Marion, Lamar, and Fayette. 

What you see up there where the TN counties are still included is false - the graphic is out of date, and there's nothing that I can do about that. But understand that Giles, Lawrence, and Wayne counties were cleared from the watch by the National Weather Service in Nashville. 




10:23 - All right, and as these storms move into Cullman and Walker Counties, they are expected to stay under severe limits but still be strong thunderstorms that could include wind gusts up to about 50 miles per hour and some small hail. 

And I'm running my laptop on battery power as a precaution against the lightning, just in case, because I'm starting to see flashes and hear thunder. You have to use good sense even when you get some organized summer storms . . . 




10:29 - Note from the Weather Service in Huntsville that these storms have reinvigorated with especially a lot of lightning. 



 
10:42 - And the cluster of strong thunderstorms continues to pass through places like Cullman and Sipsey...
