.KEY MESSAGES...
- Summer-like 90s return to the forecast soon and stick around for awhile.
- A condinued dry weather forecast will only exacerbate drought conditions and heighten fire danger as the week ensues.

.DISCUSSION... Issued at 1235 PM CDT Tue Sep 9 2025
One last nice, crisp, cool morning with 40s for lows will disappear for awhile now, as the warmup has commenced and shows no soon signs of abatement. Pattern evolution will see H5 heights rise toward 590 DM by week`s end, as a stout high pressure ridge aloft centers over the country`s mid-section. H8 temps more than double in that same time frame, translating to a movement into and thru the 80s starting today, pushing 90F as soon as tmrw, and firmly into/rising 90s heading into the weekend, when peaks in the mid 90s are expected. Dew points in the 40s this morning rebound thru the 50s this work week, struggling toward but having a hard time getting past 60F. An overall lack of moisture under the synoptic scale sink of the anti-cyclone will keep most pops at bay and silent, which will only exacerbate our current drought conditions and heighten fire danger with time as fuels dry out. Fortunately, the anti-cyclone also keeps winds generally at bay as well, and still abundant leafing coverage offers some mitigating shelter to boot.

.AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/... Issued at 1235 PM CDT Tue Sep 9 2025
A developing warm advection pattern will allow for some sensible weather influences despite the overall grip of high pressure strengthening and keeping mostly Visual Flight Rules as the prevailing forecast. Daytime heating may allow for genesis of FEW-SCT bases at 5-7K FT AGL, while time/height cross sections show condensation pressure deficits perhaps dropping just enough to support some mid-high level base potential as well, wrt the lifting wave seen on satellite nearby. About the only risk for flight restrictions will be in the form of short-lived daybreak MIFG (most probable at prone locales), as gradually rising dew points nibble into the still 4-5+F TDD spreads shown in 3 hour guidance.
