Discussion... 


A reinforcing cold front located across the northern part of the 
midsouth will push through the remainder of the midsouth overnight. 
Drier and cooler air will filter in on northerly winds behind the 
front as high pressure builds in. Friday will be much cooler with 
highs in the 70s along with very comfortable humidities. Made a 
few minor tweaks to the sky conditions otherwise forecast looks good.

Skies are mostly sunny across the forecast area this afternoon 
with temperatures ranging from the lower 70s to lower 80s. A cold 
front is moving through north Mississippi at this time and should 
be south of the forecast area later this afternoon. Behind the 
front drier air is moving into the region making for a very 
comfortable afternoon. 


High pressure will build into the region tonight which will keep 
skies mostly clear and diminish winds. With clear skies and light 
winds temperatures will drop into the 50s. With high pressure 
still in place on Friday and winds remaining from the north 
temperatures will be rather cool with highs in the low to middle 70s. 
Friday night will be even cooler than tonight with many locations 
in the eastern half of the forecast area seeing temperatures in 
the 40s by early Saturday morning. 


By Saturday...winds will be shifting to a more southerly direction 
which will start to bring warmer air to the region. A warm front 
will lift north toward the forecast area with some isolated 
thunderstorms possible over extreme northern sections after 
midnight. By Sunday...the warm front will be just south of the 
forecast area with a slight chance of thunderstorms expected. 
Temperatures Sunday will be back to normal levels with highs in 
the low to middle 80s. 


The frontal boundary is forecast to stall across the forecast and 
gradually weaken Monday and early Tuesday with some thunderstorms 
possible. By Tuesday night...the front should be gone with a 
return of dry weather for Tuesday night through Wednesday night. 
A new cold front will move into the plains states on Thursday with 
some isolated thunderstorms possibly moving into the region ahead 
of the front. Temperatures from Monday through Thursday will 
slowly warm up with highs on Thursday in the middle to upper 80s.
