575 FXUS63 KIWX 240540 AFDIWX Area Forecast Discussion National Weather Service Northern Indiana 140 AM EDT Thu Sep 24 2026 .KEY MESSAGES... - Slightly below normal temperatures (coolest on Friday) continue into the weekend with a return to slightly above normal temperatures in the early to midweek period next week. - An extended period of dry weather is expected today through Tuesday, with next rain chances not until the middle of next week. && .DISCUSSION... Issued at 132 AM EDT Thu Sep 24 2026 Our upper low that`s brought moisture into the area continues to move southeastward slowly today so that it resides in the Mid-Atlantic and Southeastern States by this evening. Vorticity continues to dampen across the area today and with east winds, a thin layer of cloudiness is expected to reside across the area. This is until an area of dry air advection pushes through this evening. RAP time sections from last night which showed this erosion of moisture below 850 mb last evening and hanged onto low stratus, but it certainly makes sense that this boundary coming through this evening would erode the thin layer of lingering stratus. Following that, another vigorous upper shortwave dives southward along the eastern coast of Lk MI later Fri. However, enough dry air resides across the area that it should be a dry passage. Additionally, with it being on the front edge of a surface high pressure system edging into the area, gradient winds look to stay weak. During this late week period, low teens Celsius at 850 mb could be tapped into to, with the best chance of this happening today south of US-30 and west of US-31, where the better low level lapse rates reside. Otherwise, Friday appears to have weaker low level lapse rates allowing for sub-70F degree highs. Highs surpassing 70F appear to edge into the area for the weekend as the shortwave dampens over Lk MI and the vorticity from the strong nor`easter across the Northeast backs westward. Lows are expected to be securely in the 40s from Friday night through Sunday night so it`ll feel cool at night then. More substantial warm advection finally works its way into the area between Tuesday night and Wednesday as a Pacific trough deepens and works northeastward. There`s some question on timing of arrival of the warmer air so highs between Tuesday and Wednesday still have some uncertainty. Increasing confidence of highs surpassing 70F area-wide on Wednesday and perhaps Thursday as 20 to 30% chance for highs >79 degrees occur from White county to Jay county. Thunderstorms could be possible between Tuesday night and Thursday depending on the timing of the system into the area. && .AVIATION /06Z TAFS THROUGH 06Z FRIDAY/... Issued at 132 AM EDT Thu Sep 24 2026 A thin layer of stratus continues to remain across the area until a theta-e boundary between moist and dry air swings through pushing drier air into the area later today into tonight. As such, expect MVFR CIGs to prevail until then. Light rain and drizzle appears to have subsided with the better moisture depths having shrunk compared to last night. Otherwise, expect a continue east wind component with times of oscillation between north and south. Given the weaker pressure gradient and slower low level lapse rates, sustained winds to 10 kts will be possible, but gusts will be fewer and further between. && .IWX WATCHES/WARNINGS/ADVISORIES...
