Usual Heat & Humidity Build, Few Weekend Thunderstorm Complexes Possible

Posted on by Marilee Caldwell

Today

Up to 87 today, but reduced humidity compared to yesterday.

A few pop-up showers will be around, but you probably won’t get one. Maybe a few of you will. One could sprout between 1pm-10pm. A thunderstorm is possible, but unlikely.

HRRR model from 1pm-10pm today

Coming Soon (aka The Rest of The Week)

Thursday should be sunny skies with afternoon highs approaching 90. Rain is not expected but we cannot totally rule it out. No cool breeze. Humidity will be about the same, but still:

Friday Into The Weekend

Rain and/or storms are possible this weekend as heat and humidity build. More moisture, more heat, means afternoon/early evening storms may sprout Friday, Saturday, and/or Sunday. NWS-Nashville is talking about two potential thunderstorm clusters — not pop ups but organized systems — that models think will

move southeast across the area, especially Saturday night and Sunday, then again on Sunday night into Monday.

These thunderstorms don’t have reliable ETAs. Models think the MCS (mesoscale convective system) will bring heavy rain at times, plus lightning, but otherwise probably not severe. That “T-storms Likely” line on your app is referring to this for Sunday afternoon. If we had to guess, that’s the most likely time to get a storm this weekend.

And don’t forget about the Saharan Air Layer!
