Severe T-Storm Watch



 The squall line is moving through Memphis. An isolated supercell or two could develop out ahead of it, large hail and damaging winds being main threats, tornado risk low with this setup.

2:02 Pm - A flood watch has also been posted overlapping these same basic areas. 


2:07 - Even got a storm producing a tornado in Calloway, Marshall, and Trigg counties in Western Kentucky on the Northern end of this squall line. The other warnings have been for large hail and damaging thunderstorm winds, further to South within line. 

2:19 - Looks like Arkansas got off with just a few severe thunderstorm reports last night, more hail than winds I think. Missouri and Illinois had some more tornado damage I believe, know I heard of some deaths from a tornado in Southeast Missouri last night. Decided not to keep up with it play by play like the Friday event. Looks like after today/tonight, basically the whole country gets a break from any severe storms for a while, at least roughly a week. And you never know how a severe season will play out. In 2021 I believe it was, we had two High Risk days for tornadoes around here about a week apart. And then nothing to compare with that the rest of the season, just a few lower-end threats and a lot of times without severe weather potential. This season might have already done its worst, but we don't know. Our main severe weather season does run through the end of May, although things tend to settle down the further we get into May most years. April is usually the worst, and we'll have to watch things closely with some times of unseasonably warm temperatures, see if that interacts with a storm system later on, like in the next few weeks. 




2:32 - At the moment not seeing any more severe thunderstorm warnings around here, the blue polygons are Special Weather Statements being issued for winds of about 40 mph or so, enough to break tree limbs and blow stuff around, but under severe limits, and for small hail up to about a half-inch in diameter.


2:36 - Way up in Western Kentucky, there is a Severe Thunderstorm Warning affecting several counties that mentions that a tornado is possible within the larger swaths of damaging thunderstorm winds along the squall line. 

2:41 - Looks like that tornado that hit Glen Allen, Missouri overnight has been rated a high-end F-2 (or EF-2 if you wanna' be anal about it) for the time being. Five people were killed in the storm.




2:58 - Got a severe thunderstorm warning for Hickman, Humphreys, and Perry Counties up in Middle Tennessee. One of the communities mentioned in the warning is called Bucksnort. Anyway we have a few showers moving through mainly Colbert and Franklin Counties in Northwest Alabama, but staying well under severe limits, and really not seeing much lightning.




3:34 PM - Got a strong thunderstorm moving through Waynesboro, but even in the squall line back in Mississippi, the storms are staying under severe lmits for now. Still may be producing gusty winds and small hail. 




3:43 - And now we have a Severe Thunderstorm Warning for Wayne, Lawrence, and Lewis Counties in Southern Middle Tennessee. 




3:57 - The wind really does look rough in that storm.




4 PM - And SPC is not expecting to have to issue another watch further downstream. Storms are expected to weaken as they move further into Alabama.

4:02 - This storm affecting places from Waynesboro to Gordonsburg to Henryville is capable of half-dollar sized hail and wind gusts of 60 miles per hour. Warning continues until 4:15.

4:11 - John Tune, TN had a wind gust of 56 knots/64 mph. The city of Nashville is included in a Severe Thunderstorm Warning now. That was the John Tune Airport.
