PREV DISCUSSION... /issued 403 AM CDT Thu Jul 29 2021/
Presently, temperatures are into the mid to upper 70s with patchy
fog along the Tennessee River. Whitesnake sang it best, "Here I
go again..." telling you we have another Heat Advisory for all of
the Mid-South from 10am to 8pm. Temperatures in the mid to upper
90s with heat indices 105F-110F this afternoon.
For Friday, with the high pressure still parked over us temperatures
look to hit the century mark for at least parts of the Mid-South.
With heat index values climbing around the 110F mark some parts of
the area may need an Excessive Heat Warning. This is being watched
closely.
As we head into the weekend, amplification of the ridge over The
Rockies and the trough over the Great Lakes will return us to
northwest flow. A cold front will advance towards the region
Saturday evening. This cold front will do us all a solid by bringing
two things, 1. widespread rain through Sunday into the Monday and 2.
cooler temperatures and lower humidity behind the front. I can't
express in any written words how EXCITED I am at this prospect.
Temperatures only into the upper 80s and low 90s with overnight lows
in the upper 60s and low 70s. This pattern hangs around through
middle of next week, so rain and cooler temperatures look to stick
around through this timeframe.
