.NEAR TERM /Now Through Wednesday/...Zonal flow over the 
Southeast will see a building ridge over the Southern Plains and a 
shallow trough forming over eastern portions of the Southeast as an 
upper level shortwave trough digs south over the eastern Conus. A 
weak cold front will move south over the southeast this afternoon 
through tonight, eventually stalling near the northern Gulf Coast 
early Wednesday morning. A very dry airmass is present over majority 
of the Southeast, with little rain indicated by radar stretching in 
a band from northwest Louisiana across central Mississippi to 
northern Alabama reaching the ground. 

For the forecast, with the dry airmass in place over the forecast 
area, any significant rain reaching the ground is expected to be 
confined to northernmost portions of the forecast area and points 
north, in a band of higher Gulf moisture stretching across this 
area. Temperatures over most of the forecast area are expected to 
rise to well above seasonal norms this afternoon, topping out in the 
upper 60s to around 70 over most of the forecast area, the exception 
will be a band across northern-most portions of the forecast area 
seeing increased cloud cover and a bit of evaporational cooling, 
with temperatures rising into the low 60s these portions of the 
forecast area. Tonight, low temperatures around seasonal norms are 
expected, with a bit below along and north of Highway 84 and a bit 
above south. Low temperatures mainly in the 40s across the forecast 
area are expected. Wednesday, cooler air will move south across 
portions of the Southeast, with areas along and north of Highway 84 
affected the most over the forecast area. Any residual rain will 
have moved off with the passing upper shortwave system. High 
temperatures ranging from around 60s along and north of Highway 84 
to upper 60s closer to the coast.
