The episode as NWS PAH wrote it up.
During the first week of the month, two storm systems moved out of the southern Plains. Scattered showers and thunderstorms brought around an inch of rain on average, while a few locations received up to 2.5 inches. Rises on the Ohio River were sufficient for some minor flooding in a few areas.

Area Forecast Discussion National Weather Service Paducah KY 554 PM CDT Wed May 11 2022 .UPDATE... Updated aviation section for 00z taf issuance && .SHORT TERM...(Tonight through Friday night) Issued at 239 PM CDT Wed May 11 2022 An unseasonably strong 500mb ridge is parked overhead today with its axis stretching from the Great Lakes to the western Gulf Coast. This is resulting in another day of record/near record high temperatures with 2 PM readings ranging from 87-91 degrees. Dew points in portions of southeast MO and southern IL are in the mid 70s, which is at or above the 99th percentile for May. This is resulting in heat index readings in the upper 90s to around 100. Slightly lower values are observed further to the east, but still rather unusual for this early in the season. An isolated shower or storm still can't be ruled out across the east half of the region the rest of this afternoon, but chances appear quite low given the ridge overhead. The upper ridge will gradually break down over the next couple of days as a large scale upper low off the southeast coast slowly churns westward to the southern Appalachian region by later Friday. Thursday will feature more of an easterly flow across our region, which will bring in much drier air that is currently located over far east KY. This airmass may struggle to make it more than half way through our region by Thursday afternoon though. Thus while temperatures will be within 5 degrees from west to east, dewpoints will be upwards of 15-20 degrees lower in the Evansville Tri-state and Pennyrile region of west KY compared to southeast MO. End result will be a much more pleasant day across our eastern counties. An isolated shower or storm can't be completely ruled out over southeast MO during the afternoon, but chances are once again quite low so have left PoPs silent for now. Much of the daytime hours on Friday may end up dry, but some convection may seep into the region from the west as westerly flow begins to increase in conjunction with shortwave energy across the Northern Plains. Guidance is hinting at the best chance being Friday night though, and especially across the west half of the region. .LONG TERM...(Saturday through Wednesday) Issued at 239 PM CDT Wed May 11 2022 There is moderate confidence in a typical summer-time pattern developing for the weekend and into next week. The upper ridge will finally give way on Saturday as troughing from the southeast lifts north and westerly flow impinges on the area from the Plains. The surface pattern will be weak, so convection will likely be diurnal and isolated to scattered in coverage. Given weak wind fields individual storms will be short-lived. There continues to be considerable spread in the medium range ensemble guidance with respect to the strength and southwestward extent of a upper low/trough pushing into Ontario Sunday and then into the Great Lakes vicinity Monday. The NBM brings an associated cold front through the area Sunday into Sunday night, but has just low chance PoPs. While there does seem to be an increasing trend toward the region drying out for Monday, there is likely to be a more organized area of convection along and ahead of the front Sunday. The NBM PoPs seem underdone, and if some better mid and upper flow can catch up to the front, a few strong to severe storms are not out of the question. Assuming that the boundary clears the area Sunday night, Monday should be dry, with cyclonic west northwest flow aloft over the region. Unfortunately, we are rapidly approaching summer and northwest flow is rarely clean and dry for very long. Impulses in the rather progressive flow could bring showers and storms back into the region Tuesday and/or Wednesday. Temperatures will generally remain a bit above normal through the period. && .AVIATION... Issued at 554 PM CDT Wed May 11 2022 Areas of scattered diurnal cumulus clouds will dissipate with loss of daytime heating around 00z. Light southeast winds will become nearly calm. The overnight hours will be clear. A little patchy fog cannot be ruled out around sunrise, mainly in srn Illinois and se Missouri. On Thursday, scattered cumulus clouds will again form by midday west of the kevv and kowb taf sites, including kmvn and kpah. Winds will become east to southeast at 5 to 10 kt. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None. IN...None. KY...None. && SHORT TERM...SP LONG TERM...DRS AVIATION...MY
