DISCUSSION

Issued at 142 PM CDT Sun Sep 6 2026

Looking at increasing northeast winds today with sfc high pressure centered over the Great Lakes. Even with the cold front just south of the area this afternoon, the cooler and drier air is lagging behind a bit. Therefore a Heat Advisory is in effect till 8 PM for areas south of a line from Greenville, MO to Murray, KY for one more day of heat indices over 100 degrees. Tomorrow (Labor Day) still looks like the best day with highs right around 90 and dew points in the mid-upper 50s. However, the upper ridge to the west looks to shift and build back over the region and brings us a warming trend for Tuesday and Wednesday unfortunately.

Tuesday and Wednesday look to be uncomfortably hot again with highs in the mid to upper 90s Tuesday, and highs in the upper 90s to 100 in a few places Wednesday. Dew points back in the mid-upper 60s are expected both days. This puts heat indices back into the 100-105 degree range on Wednesday afternoon. The ridge breaks down to weaker zonal flow by Wednesday morning and allows a cold front to swing through Wednesday night into Thursday. NBM PoPs have increased in the north this run to 70% up north and closer to 30% down south Wednesday night. Thursday morning most of the Quad State is under 50- 70% PoPs with chances diminishing in the afternoon and evening. QPF has also increased across the north with now around 0.75" up to 1.25" (this high end being more localized) from Wednesday night through Thursday.

The weak zonal flow aloft continues through the weekend allowing for some messy 15-25% PoPs each day. However, temperatures will be more pleasant and hover right around or just above normal.

AVIATION /00Z TAFS THROUGH 00Z TUESDAY/

Issued at 545 PM CDT Sun Sep 6 2026

VFR conditions expected through the period as high pressure over the Great Lakes produces dry northeasterly flow across the region. Winds should remain elevated overnight, generally staying in the 4-5 kt range before increasing to around 6-8 kts during the day on Monday. Mainly clear skies are expected aside from a FEW high cloud.
