743 FXUS61 KILN 070502 AFDILN Area Forecast Discussion National Weather Service Wilmington OH 102 AM EDT Mon Sep 7 2026 .WHAT HAS CHANGED... No significant changes. && .KEY MESSAGES... 1) Tranquil weather to start the week. A cold front will then move through Wednesday night into Thursday. && .DISCUSSION... KEY MESSAGE 1) High pressure centered over the Great Lakes will keep a dry and cooler airmass in place throughout the day on Monday. By Tuesday, the high begins to shift east, bringing a return of southerly flow and a warming trend. Temperatures on Tuesday rise into the upper 80s, while low 90s are forecast for Wednesday. A short wave will track from the northern Plains across the upper Great Lakes, pushing a cold front into the area Wednesday into Thursday. Given how far removed ILN is from the warm sector of the system, moisture ahead of the front isn`t robust. However, as the front slowly sags down into the region, it looks to nearly stall out (or be very slow to progress) and PWATs along the front are forecast to be around 200% of normal. While, at this junction, severe weather doesn`t look overly likely, any training storms along the slow moving boundary would introduce a flash flooding threat. While exact timing on FROPA is a bit ambiguous, ensembles suggest that it will be passing through the FA on Thursday. Once this front passes through the region, cooler and drier air will once again filter in for the end of the work week. && .AVIATION /03Z MONDAY THROUGH FRIDAY/... No major changes from the previous TAFs. Northeast winds overnight will increase again on Monday and become more easterly. Patchy river valley fog is possible overnight, so have dropped LUK accordingly. Any fog will burn off shortly after sunrise and we`ll again have some patchy diurnal cu across the region. OUTLOOK...Thunderstorms possible Wednesday night into Thursday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None. IN...None. && $$ DISCUSSION...Aiena AVIATION...Aiena
