.DISCUSSION... Issued at 1229 PM CDT Wed Sep 10 2025
Broad cyclonic flow over the Great Lakes region continues to lead to subsidence and and overall dry weather pattern over the quad-state. All moisture for rain of any significant remains shunted well to the south over the Gulf. Surface dewpoints have crept up just a little over the last 24-48 hours with afternoon mixing only reducing them into the low 60s and we saw a few sprinkles this morning over Owensboro/Evansville but abnormally/dry drought conditions look to remain in place by and large through the next 7 days. The broad cyclonic flow to our northeast advances southeastward a bit leading to increasing surface ridging over GA/NC/VA that further cuts off moisture return from the east. 500mb heights increase slightly and afternoon maximum temperatures follow suit as we should head above 90 in most locales tomorrow and stay that way for the next several days.
By the weekend we get just a whisper of deeper low-level return flow but it still looks insufficient for appreciable rainfall and strong mid level subsidence and surface heating will likely mix out any sensible increase in low level humidity/moisture that would lead to higher heat index values or precip chances. GFS/ECMWF deterministic and ensemble members point towards the overall 500mb troughing shifting more to the west by day 7-10 that could result in a little different pattern, but for the most part it looks like a safe bet to count on it being more dry than not for the foreseeable future.

.AVIATION /00Z TAFS THROUGH 00Z THURSDAY/... Issued at 605 PM CDT Wed Sep 10 2025
Patchy ground fog may develop late tonight. This may be slightly more likely in the OWB/EVV areas which received some light rain earlier today and their cross-over temperatures are higher. Otherwise, just some SCT mid and high cloud through the period. Calm winds overnight will become light and variable tomorrow afternoon, generally remaining under 5 kts.
