KEY MESSAGES

- A prolonged duration Heat Advisory remains in effect thru Friday for daily heat indices 100-110 degrees.

- A small chance of showers and thunderstorms Friday and Saturday will help transition toward an end to the prolonged duration heat.

DISCUSSION

Issued at 1212 PM CDT Mon Aug 31 2026

Strong high pressure at the surface and aloft remains locked in here this week, pumping up the heat and humidity in the process. Our prolonged duration Heat Advisory running the course of the week looks to survive with ease, with all sites reaching into the triple digits daily. Pushing past 105 degrees will be more hit and miss, and tops the whole week looks to be near but not in excess of 110 degrees, at least by means of the current data. Wednesday-Thursday play the hottest, with most sites settling somewhere from 103-106 degrees, though there may be sporadic local exceptions slightly higher or lower.

Longer-range modeling still brings a chance of pcpn in toward the week's end, namely Friday-Saturday; but the chance is small, smaller than it was yesterday, and as such, if the trend continues, it's possible the headline gets lengthened into Saturday. We won't jump on that this early, but it bears watching as the week goes on.

AVIATION /18Z TAFS THROUGH 18Z TUESDAY/

Issued at 1212 PM CDT Mon Aug 31 2026

Strong high pressure will keep minimal cloud and wind within a predominantly Visual Flight Rules forecast regime. The only exception might be patchy fog late in the night or during the early pre dawn hours that might offer temporary vsby restrictions, but the chance is low enough to preclude from the forecast at this writing.
