Good Morning! We’ve had a wet week so far with heavy rains and flooding across parts of the region, but an upper-level ridge and surface high pressure system should decrease our rain chances for the weekend.

Of course with temperatures nearing 90 degrees today and dewpoints in the 70s, there should be no lack of instability and mugginess in the air. Don’t be surprised to see scattered storms pop-up from midday on, similar to yesterday.

With the available parameters in place, we have the possibility of seeing a few storms meet severe criteria. The SPC has placed all of south central Kentucky in a Slight Risk for severe weather this afternoon and evening:

Main threats with this particular setup will be torrential rainfall, along with damaging winds.  Although not significant, we’ll have a marginal possibility of seeing a tornado or two develop.


 

Saturday 7/11 – Sunny; Iso’d Afternoon Storms – High 92˚ / Saturday Night – Partly Cloudy – Low 73˚

Much of this weekend looks to be a broken record forecast – hot and humid during the day and a chance of hit-and-miss storms in the afternoon. High temperatures will be a tad warmer Saturday and Sunday as southerly winds pull warm, humid air up from the Gulf. And you know what that means?

Yep, you guessed it. More storm chances on Saturday afternoon with forecasted CAPE values (storm energy) between 2000-4000 j kg-1, or in other words, very unstable air favorable for storm development.

Don’t expect too much to change for Sunday. You’ll probably want to keep cranking your AC.


Sunday 7/12 – Sunny; Iso’d afternoon storms – High 92˚ / Sunday Night – Partly Cloudy – Low 73˚

(See above) But really, Sunday looks to be a repeat of Saturday with more of the same muggy weather. High temperatures will likely be in the low 90s and dewpoints in the 70s again.  Heat index values will flirt with 100˚!

I’m not sure what I’d rather have – endless rain or super uncomfortable heat. Either way, find a way to stay cool on Sunday whether it’s by the pool or in front of the air conditioner. I won’t judge.
