Special Weather Statement (TN)



Looks like this strongest storm in the line is staying under severe limits, but producing some gusty winds and small hail along with a lot of lightning.  



2:28 AM - Even though it's the wee hours of the morning, the air is pretty soupy, dewpoints up in the upper 60's. And we'll see if any of these storms tap into that and the wind shear, which is not a ton, but is sufficient to support a few severe thunderstorms, if all the other ingredients come together at the right time. 



3 AM - Still just seeing gusty winds and heavy rain with parts of this line, and of course a good bit of cloud to ground lightning. The threat of more severe weather is low, but still on a night like this, good to keep an eye on the radar in case anything tries to get out of hand again. For now the storms are behaving. 



3:19 AM - If we do see anything else go severe within this line, it should stay isolated. Even out in Arkansas and Louisiana, they are not going to issue any more watches right now, the chance for severe storms is so low. It sure did get active for a while though earlier in the night, more than expected around here, or at least the timing was a little ahead of schedule. 



3:35 - Nonetheless we have to remain alert for the isolated problems. This storm back in Mississippi has reached severe limits and prompted a warning. 



And it is showing enough broad rotation that the text of the warning advises people in the path (back around Tupelo) to remain alert for a possible tornado that could develop quickly from this severe thunderstorm. 

So the night is not over yet. 

The Storm Prediction Center just posted a mesoscale discussion for us. So I'm going to make a separate post for that.
