976 FXUS63 KIWX 151634 AFDIWX Area Forecast Discussion National Weather Service Northern Indiana 1234 PM EDT Wed May 15 2024 .KEY MESSAGES... - Showers diminishing today then a short dry period tonight. - More showers with scattered storms at times Thursday through the middle of next week. Locally downpours possible, but severe storms are not expected through Saturday. - Better chances for severe storms next week Monday through Wednesday. - Highs in the 70s to low 80s into the middle of next week. && .DISCUSSION... Issued at 150 AM EDT Wed May 15 2024 A cluster of smaller systems were associated with the upper low that was drifting east over the Ohio River. Part of the energy with this system was over the forecast area and had produced locally heavy rainfall over 2" yesterday into last night. SPC mesoanalysis showed precipitable water values values ranged from 1.25 to 1.35 inches which were close to the 95th percentile for this time of year. Saturation was near 100% per HRRR and GFS BUFKIT sounding up to 250 mb. The atmosphere will remain very efficient in producing rain, although the upper level system will continue to accelerate east in reaction to teleconnections energy upstream. The next upper level system will reach the area Thursday and is expected to produce local downpours into early Saturday will basically have same environment as today. An EML (Elevated Mixed Layer) should arrive Sunday ahead another system in the series of upper level trofs as the main/longwave trof lingers over western North America. While is is still quite a ways out, initial thoughts include an environment that may be favorable for severe storms next week Monday through Wednesday. && .AVIATION /18Z TAFS THROUGH 18Z THURSDAY/... Issued at 1234 PM EDT Wed May 15 2024 Mixout to a sct-bkn VFR stratocu field the story this afternoon as drier/subsident air is finally making inroads within northeast flow. Ridging through the column does work in tonight with clearing skies and lighter winds. This may allow for some BR formation at KFWA toward daybreak given lingering near sfc moisture. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...None. OH...None. MI...None.
