459 FXUS63 KIWX 080920 AFDIWX Area Forecast Discussion National Weather Service Northern Indiana 520 AM EDT Sat Jun 8 2024 .KEY MESSAGES... - Scattered showers today, more numerous near the Michigan border, ending tonight - At this time, the only chance for rain this upcoming week is Thursday night which includes a chance for showers and storms. - Cool today through Tuesday with highs in the 70s, becoming very warm Thursday into the following weekend with highs in the 80s. 90s possible late. && .DISCUSSION... Issued at 137 AM EDT Sat Jun 8 2024 An upper level system was just upstream from IL to far east KS. This system will move east today and bring showers to the area. Continued to keep thunder out given the lack of instability and insufficiency of larger scale lift. The GFS has been consistent with this system and still favors timing in about a 9 hour window from 18Z to 03Z early tonight per 305K isentropic analysis. The back/west side of the upper trof will remain over the region until upper level ridging builds into the area later in the week. Have kept the lone chance for showers/thunder Thursday night as a weak front moves southeast. There is an increasingly stronger signal for a hot pattern to develop just past the end of the forecast period as reflected in the latest CPC outlook (risk of excessive heat). Otherwise, highs will be in the 70s through Tuesday then highs in the 80s the rest of the week. Given 850 mb temperatures approaching 20C, highs in the lower 90s are possible just past the end of the forecast period. && .AVIATION /12Z TAFS THROUGH 12Z SUNDAY/... Issued at 520 AM EDT Sat Jun 8 2024 VFR conditions expected to give way to a period of MVFR cigs and scattered showers (best chances at KSBN) late this afternoon into this evening as a cold front sags south into northern IN. Southwest winds will pick up otherwise in advance of the front late this morning and afternoon with gusts near 20 kts. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...None. OH...None. MI...None.
