444 FXUS61 KILN 250221 AFDILN Area Forecast Discussion National Weather Service Wilmington OH 1021 PM EDT Sat May 24 2025 .SYNOPSIS... Mostly dry and cool conditions will remain in place through the weekend. More widespread rain chances will return on Tuesday while below average temperatures persist through most of the upcoming week. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... Quiescent night. Mid and high clouds will increase late tonight. Winds will remain light. Forecast lows look reasonable. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/... A midlevel S/W will track through the region during the short term period within the broad NW flow aloft, resulting in an increase in mid/high level moisture through the daytime. While very dry air will remain entrenched within the LL profile, efforts to saturate the profile may eventually lead to a few sprinkles or spotty light SHRA through the daytime. Confidence in this occurring is quite low given the antecedent depth of dry air near the sfc, but suppose that a slight chance of light SHRA cannot be ruled out, particularly near/S of the OH Rvr by mid to late afternoon. By early evening, a better push of dry air will begin to once again settle into the area, overspreading from the N through the night into Monday morning. This should keep the area dry for the daytime Monday, too. Temps on Sunday will be a few degrees cooler than will be the case today, owing to more widespread cloud cover and the patchy sprinkles or very light SHRA. Highs will generally top out in the mid to upper 60s before bottoming out in the upper 40s to lower 50s into Monday morning. && .LONG TERM /MONDAY THROUGH SATURDAY/... Monday will be a transition day as upper level ridging is shunted east as a digging trough over the Great Plains develops into a closed low. As such, clouds increase and thicken on Monday and temperatures become a tad warmer, rising into the low 70s (still 5- 10 degrees below average). However, we should remain dry through most of the daylight hours. Precipitation from the low pressure to our west begins to overspread the region Monday evening. We remain on the northern side of the surface low and the more robust pool of instability remains well to our south, so, for now, have excluded thunder from the grids during this time. Rain showers continue on Tuesday, with some weak instability building in during the afternoon hours as the low pushes north and the warm front moves into the region. Broad brush QPF suggests a tight precip gradient spanning from lesser amounts (0.25-0.5 in) along and north of I-70 to higher amounts along the Ohio River and farther south (0.75 to 1+ inch), with locally higher amounts likely where heavier pockets of rainfall occur. Foliage throughout the area has come in by now so this should help with runoff, but cannot rule out some isolated flooding concerns where storms train. Highs on Tuesday are cooler thanks to the thick cloud cover and rain cooled air, only reaching the mid 60s. Guidance gets a bit more muddled as we head into mid-week and beyond. The upper level closed low will remain over the Great Lakes/ Mid Atlantic region, slowly progressing east toward Quebec through the end of the working week. Closer to the surface, however, there are weak/ loosely forced signals for on and off rain as impulses travel through the southwesterly flow. Have kept episodic chances for rain showers in the forecast heading into the weekend. Right now, ensemble guidance suggests that temperatures rise back to near normals (perhaps a tad below) from mid-week into the weekend. && .AVIATION /02Z SUNDAY THROUGH THURSDAY/... VFR will continue. Remaining cumulus will dissipate early in the period. Beyond that there will be a mix of mid and high clouds which will evolve into a fairly solid mid deck on Sunday. Winds will become light and then increase to 7 to 10 kt out of the northeast on Sunday. OUTLOOK...MVFR to IFR ceilings and visibilities are likely Tuesday into Wednesday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None. IN...None. && $$ SYNOPSIS...KC NEAR TERM...
