9/7: Quick Warmup before Mid-Week Storms and Much COOLER Blast

Good Sunday,

Talk about a "cooler" Sunday we experienced here in Middle TN with Highs only in the Upper 70°s before late afternoon Sunshine made a peek.

Slightly above Average Temps will make a Return though as Ridging will develop from the South and spread Mid-Upper 80°s across the region.  I do think Wednesday could be the 'Warmer' day with highs creeping in Upper 80°s-Lower 90°s with Humidity building back in.
*NOTE* the Much cooler Air surging from the High Plains into the 50's/60's in some spots.  Light SNOW is possible up in Wyoming, Montana and maybe South Dakota
NAM FORECAST TEMPS ON WEDNESDAY

STORM CHANCES on Thursday?
A sharp Cold Front will blast farther South towards the Ohio and Tennessee valleys with chances of Strong to Severe Storms, but right now it looks to be Small Hail and High Winds as the greatest risk.  Timing is still hard to tell, but from Late Morning to Early Evening Thursday is the best Time-frame when the Storms should drop through. 

GFS Precip at 1PM Thursday

BEHIND the Front, Frost is possible in the Northern Plains/Great Lakes, but ahead of it is will be the potential of Strong Storms from the Northeast down towards the ArkLaTex.













EARLY FALL for MiddleTN?

Long Range models may suggest that after Wednesday, that could be our LAST 90°+  Day, but as how Climate changes, we can't just assume right now. However, below average Temps about 5-10° are likely beginning Thursday once the Front drops. GFS/EURO Models suggest anywhere from 74-79° for daytime Highs ~ OPEN A/C! We will see how the trends continue through the week with the Temps and any Storm Threat for MiddleTN.
