215 FXUS63 KLOT 141840 AFDLOT Area Forecast Discussion National Weather Service Chicago/Romeoville, IL 140 PM CDT Sat Sep 14 2024 .KEY MESSAGES... - Dry conditions and summer-like warmth will persist through at least next week. && .DISCUSSION... Issued at 139 PM CDT Sat Sep 14 2024 Have maintained dry conditions in the forecast through at least the upcoming week and potentially through next weekend. Little low and mid-level cloud cover today speaks to the lack of moisture throughout the column as the area remains situated between a mid-level wave lifting northeastward toward Minnesota and the remnants of Post Tropical Cyclone Francine over the mid-Mississippi River Valley. Correspondingly, the chance for sparse mid-level showers brushing the western CWA tonight continues to diminish. With another tropical system poised to develop off the Carolinas early next week before drifting N/NNW across the Mid- Atlantic, the overall flow across the east half of the CONUS will remain blocked. This should keep our area firmly situated on the western extent of an expansive and persistent surface ridge. Daytime highs in the mid to locally upper 80s and lows in the upper 50s to mid 60s will be common amid southeast to easterly winds. Worsening drought conditions will be the main focus through the forecast period with nearly our entire forecast area in D0 (abnormally dry) status and a couple small areas now in D1 (moderate drought) status. Kluber && .AVIATION /18Z TAFS THROUGH 00Z MONDAY/... Issued at 1208 PM CDT Sat Sep 14 2024 No forecast concerns through the TAF period as high pressure will remain over the Great Lakes. East-southeast winds are expected to prevail through Sunday afternoon with speeds generally in the 5 to 10 kt range during the day and 4 to 5 kt range overnight. Though, a lake breeze will move through GYY this afternoon resulting in a more northeast wind direction. Otherwise, expect some SCT to BKN VFR cirrus to linger overhead through the period.
