Flash Flood Watch In Effect Until Monday Afternoon

This afternoon’s storms produced a few downed trees and limbs, and some localized flooding. Those storms have departed south and east down I-24.

More Storms Tonight?

From around 4 PM to 6 PM, the rain should switch “off.” The HRRR model predicts more rain beginning around (maybe before?) 7 PM, and continuing for at least a few more hours.

The strength of tonight’s rain/storms is in question. This afternoon’s storms squeegeed a lot of our moisture, but “forcing” will be strong as these storms approach; hence the uncertainty. The HRRR model thinks tonight’s event will be just rain, but other models think there still may be enough juice left to fire up more thunderstorms.

The Storm Prediction Center still has us in its severe weather outlook, mostly for damaging straight-line wind potential.

This looks like a low-end severe concern. We’ll be tweeting it tonight.

A lot of rain has fallen. The purple indicates radar estimates of 1.5″ to 2″ or more:

Rain should continue overnight, and may even continue through lunch Monday.

At 547 PM, NWS-Nashville issued a Flash Flood Watch because “heavy rainfall from a slow moving front this evening, tonight, and Monday could cause flash flooding issues.”

Monday thru Wednesday: Less Humid

A cold front arrives Monday, and will scour away the humidity. It’ll still be hot, but you’ll love Monday – Wednesday, with no rain forecast.

Humidity returns Thursday through the weekend, and with it, another chance of typical-summery afternoon rain/thunderstorms, with maybe another cold front to create another rain/storm event next weekend.
