DISCUSSION

Issued at 100 AM CDT Fri Aug 14 2026

Strong high pressure keeps us baking thru the weekend. Highs yesterday were largely in the mid-upper 90s, with some lower 90s northeast, and HI's topped out in the 102-113 degree range, with most sites settling in the 105-110 degree range. We should see similar output this weekend, with maximum air temperatures AOA yesterday's numbers, reaching around 100 degrees even (SEMO Ozarks) as dew points hover in their same ballpark. The prolonged duration Extreme Heat Warning thus continues for all localities thru the weekend.

Any near term weekend pops will be glancing blow pops, from the upstream action to our north that tops the ridge and spills down toward I-70. Further south down here, a 12-13C cap at H7 will be tough to overcome with little/no forcing offered til the actual front drops into the picture. Its Sunday night passage is when pops pick up with a little bit more earnest and the stifling air mass is turned over as northerlies draw in some (relative to the extreme heat) cooler/drier air to begin the new work week, ceasing our headlines with a return to more climatologically 'normal' temperatures and humidity.

Another front's mid week passage leads to an additional pops spike by Wednesday night. This one results in a nice, reinforcing shot of cooler and drier air that might well bring some pleasantry in the form of highs in the 80s again as dew points drop into, and possibly? thru the 60s, if all pans out as it looks now.

AVIATION /06Z TAFS THROUGH 06Z SUNDAY/

Issued at 100 AM CDT Sat Aug 15 2026

In this high pressure dominated forecast, there will be little in the way of clouds excepting FEW diurnal bases and/or FEW-SCT mid or high debris cloud blow-off. Isolated storm chances look to remain low enough and far enough away from the terminals such as to preclude their mention at this writing.
