.DISCUSSION...
Issued at 255 PM CDT Tue Jul 7 2026

Through Wednesday night: For this afternoon at least, the forecast
area is getting a temporary reprieve from the active convective 
pattern, but a semi-organized convective cluster over north MS is
developing southward, and outflow from this system this should 
increase thunderstorm chances along the Hwy 82 corridor as we 
approach early evening. Any storms that develop should diminish 
later this evening with mostly quiet weather conditions overnight.
Going into Wednesday, we may see greater diurnal storm coverage 
with the continuation of cyclonic upper level flow associated with
the LMV trough.

Thursday through the weekend: Rain chances will diminish for Thu-
Fri as the subtropical ridge rebuilds over the forecast area. 
Accompanying the building ridge will be an increasing heat danger 
risk with H850 temps approach 21 deg C and low level flow
developing a more westerly component. For now, we will message 
this threat with a heat danger graphic, but expect that a heat 
advisory will eventually be needed for portions of the area.

Early next week: Global models have a had a strong signal for a
shortwave trough rotating around the ridge and sending a boundary
toward our area in the Mon-Tue time frame, and this could support
a significant round or two of convective rainfall. Along with
this, the heat would diminish to below dangerous levels. /EC/

.AVIATION...
(18Z TAFS) Issued at 255 PM CDT Tue Jul 7 2026

Altogether expect VFR conditions across the area today. Showers and 
thunderstorm coverage will diminished over the center of the CWA,
with a thin field of storms spread over the periphery. A small 
chance exists for shallow short lived fog to develop in low- lying
areas which receive rainfall this afternoon. /OAJ/
