765 FXUS61 KILN 231539 AFDILN Area Forecast Discussion National Weather Service Wilmington OH 1039 AM EST Sun Feb 23 2025 .SYNOPSIS... High pressure will bring dry weather and a slow moderation of temperatures through Monday. Several chances for light precipitation return by early Tuesday as a warmer weather pattern develops through midweek. The best chance for widespread precipitation looks to be Wednesday evening into Thursday, but amounts should still be rather light. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... West-northwest flow with a weak mid level shortwave dropping from the Upper MS Valley across the Great Lakes today. Mid and high level clouds spill into the area - thickest across the north today. Most of the area will see abundant sunshine with some moderation to temperature. Highs will warm up with readings topping out from the upper 30s north to the middle 40s south. Light southwest winds are expected at 5 to 10 mph. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/... Skies should once again be trending clearer by/past sunset, with additional mid/high level moisture/clouds returning by the day Monday. Lows tonight generally dip into the mid to upper 20s, with warmest conditions in EC IN and WC OH where steady SW sfc flow should be maintained through the night, particularly toward daybreak as the pressure gradient tightens. The coldest spots will be sheltered/low-lying locales in the lower Scioto Valley and NE KY. The afternoon will feature some filtered sunshine, but temps should still top out in the upper 40s to lower 50s, likely the warmest day the area has seen in more than 2 weeks. This will be accompanied by breezy conditions, with SW winds of 25-30 MPH expected by the afternoon. && .LONG TERM /MONDAY NIGHT THROUGH SATURDAY/... On Monday evening, southwesterly flow will still be in place across the Ohio Valley, with broad surface high pressure drifting off the southeast US coast. The northern jet stream will become a bit more active through the rest of the week, with a few chances for rain. The first will be early Tuesday morning, though computer models have generally not been very robust with this system. PoPs will be kept in the 20-30 percent range, mainly for the northern half of the ILN forecast area. The southerly to southwesterly flow will mean that temperatures will continue to increase slightly on Tuesday and Wednesday. Highs will be in the upper 40s to upper 50s on Tuesday, and mid 50s to lower 60s on Wednesday. After the warm conditions in the daytime hours on Wednesday, another shortwave will approach the area in the WNW upper flow. This wave will also bring an associated surface cold frontal passage Wednesday night, which will bring cooler temperatures through the rest of the week. Total precipitation amounts from the Wednesday/Thursday system will likely remain well below an inch, with no significant weather impacts expected. High pressure will move back into the area for the end of the week, with a gradual warming trend (40s and 50s) expected by Saturday. Confidence is low regarding the timing for the next chance for precipitation, as there is not much model agreement in specifics as the pattern turns more amplified going into the weekend. && .AVIATION /16Z SUNDAY THROUGH THURSDAY/... VFR conditions are expected through the TAF period as some mid/high level moisture filters back into the region during the daytime, particularly for nrn sites. Skies should trend clearer once again toward 06z Monday area-wide before thick cirrus overspreads the area toward/beyond the daybreak Monday. SW winds around 5kts will increase to around 8-10kts during the daytime before subsiding once again to around 5kts past 00z. SW winds will gradually increase to around 10kts at KDAY again by the end of the period as the pressure gradient tightens. OUTLOOK... MVFR conditions possible Tuesday and Wednesday. MVFR ceilings possible Thursday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None. IN...None. && $$ SYNOPSIS...AR NEAR TERM...AR SHORT TERM...KC LONG TERM...Hatzos AVIATION...KC
