Area Forecast Discussion National Weather Service Wilmington OH 105 PM EDT Thu May 8 2025 .SYNOPSIS... After a chance for thunderstorms across southern Ohio, northern Kentucky, and eastern Indiana this afternoon and evening, cool and dry weather arrives for Friday and Saturday. Warmer air returns by the second half of the weekend. The chance for showers and storms returns on Tuesday to accompany the warmer weather. && .NEAR TERM /THROUGH TONIGHT/... Surface observations and SPC mesoanalysis reveals a cold front along I-70 slowly dropping south early this afternoon. North of the front, dry conditions persist with northerly winds limiting temperatures to the 50s and 60s. Some lower clouds are also aiding in keeping temperatures down north of the front. For areas south of the front in southern Ohio, eastern Indiana, and northern Kentucky temperatures have risen into the 60s and 70s along with some sunshine in spots. In these areas, the chance for showers and thunderstorms will increase through the afternoon especially along and south of the Ohio River as instability grows. The severe risk remains low as there is limited shear and DCAPE is minuscule. Limited wind flow could support isolated flooding issues as storm motion is likely to be slow. Shower and storm chances end for everyone this evening after FROPA. Northerly winds usher in cooler, drier air for the overnight. && .SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/... High pressure builds in from the northwest Friday through Friday night. For the daytime, mostly sunny skies with breezy northeasterly winds are expected. Forecast highs are in the middle to upper 60s. Winds drop off overnight as high pressure moves closer to the Ohio Valley. Dry, clear, calm conditions allow lows to drop off into the lower 40s for most locations. Some upper 30s are possible in sheltered areas. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... Surface high pressure will shift east across the Great Lakes Region through the weekend and off the East Coast by Monday. This will provide for dry conditions through at least Sunday. As we start to get into return flow on the back side of the high, we will also see a warming trend into early next week. Highs on Saturday will be in the low to mid 70s, increasing to highs in the upper 70s to lower 80s by Monday. An upper level low over the lower Mississippi Valley will open up as it lifts northeast across the Ohio Valley through midweek. This could lead to few showers sneaking into our south later Monday, but the better chances for showers and thunderstorms associated with this will be on Tuesday and Wednesday, with likely some diurnal component to the pcpn chances. Pcpn chances should then taper off heading into Thursday as the weakening trough axis moves off to the northeast. Decreasing heights and some pcpn on Tuesday will keep temperatures down a bit, with highs mainly in the mid 70s. We should then trend back up in temps through the rest of the long term period with highs by Thursday into the low to mid 80s. && .AVIATION /17Z THURSDAY THROUGH MONDAY/... A cold front will drop through the area this afternoon. KDAY, KCMH, and KLCK are already post frontal so rain chances are limited to none. While storms are not a threat to the northern sites, patches of scattering MVFR ceilings are being observed behind the front and may impact the sites early this afternoon. For the southern sites, the chance for showers and storms exists this afternoon into the early evening especially at KCVG and KLUK. After 0000z, FROPA is expected which brings a gradual end to rain chances for the Cincinnati sites. VFR ceilings may persist after FROPA although MVFR ceilings in the post frontal environment cannot be ruled out. Northeasterly winds from 10-15 knots persist for the northern TAF sites. Eventually, light and variable winds at the southern sites turn to the northeast to line up with the northern sites this evening after FROPA. OUTLOOK... Thunderstorms are possible on Monday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
