.DISCUSSION...

Issued at 1229 PM CDT Thu Jun 26 2025



Rest of Today through next Wednesday...A mix of clouds and sun 

this afternoon as a 591mb high pressure over the region continues 

to move towards the northeast, allowing for a mid-lvl low to 

migrate towards the west along the periphery of the ridge. Cloud 

cover from morning convection will provide some relief from the 

afternoon heat and humidity; however; heat indices could still 

reach greater the 105 degrees in areas receiving more sun than 

clouds. As a result, the heat advisory will continue through this 

evening. As the low progress westward, afternoon heating with an 

unstable airmass in place is expected to promote some organized 

convected this afternoon and evening. A "Marginal" (1 out of 5) 

risk for severe storms is in place across the CWA and damaging 

winds are the primary hazard of concern.



Heading into the weekend: the ridge is expected to start flatten 

over the southeast CONUS and a longwave trough will settle across 

the northern CONUS. Afternoon showers/t-storm chances will continue 

through the extended period as a frontal boundary is expected to 

stall north of the area and the airmass remains unstable. In 

addition to the stalled boundary, northwest flow may usher in some 

shortwave disturbances throughout the week. Widespread rain chances 

are expected (35-65% PoPs with best PoP chances east of I-55). 

Temperatures aren't expected to be as oppressive as dewpoint ranges 

in the lower 70s and highs reaching the lower 90s. Depending on 

cloud cover/rainfall received, heat indices could reach 105 degrees 

or greater. /SW/

.AVIATION...

(18Z TAFS)

Issued at 1229 PM CDT Thu Jun 26 2025



Flight categories will predominately remain at VFR categories 

through the 18Z forecast period. The only "flies in the ointment" 

will be the potential for scattered convection during the 

afternoon and early evening hours, and the potential for patchy 

ground fog and/or low stratus at a few TAF sites toward day break 

Friday morning. If any of these are observed on station, flight 

categories could be reduced to MVFR/IFR statuses for a short 

duration. Winds this afternoon will be from the southeast between 

5- 8 knots. These will subside to light to calm tonight, and will 

become southwesterly around 5 knots by late Friday morning. /19/
