Area Forecast Discussion National Weather Service Wilmington OH 1008 PM EDT Fri May 16 2025 .SYNOPSIS... Low pressure over the upper Midwest state and a trailing cold front will bring thunderstorms this evening. High pressure will offer breezy and mild conditions heading into the weekend. An upper level low will bring cloudy and cooler weather early next week. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... Scattered showers and thunderstorms will continue to push east across the region over the next few hours. We have seen an overall weakening trend in the intensity and coverage with the storms and expect this trend to continue as we head into the overnight hours and further stabilize. Lows tonight will generally be in the lower 60s. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/... Trailing surface cold front will push through the region Saturday morning. In its wake, westerly winds will gust to 25-35 mph at times. Mostly sunny skies will allow high temperatures to rise to the upper 60s in the northwest to lower-middle 70s in the southeast. && .LONG TERM /SUNDAY THROUGH FRIDAY/... Mid level ridge will translate into the area early in the period, but there are a number of models that show a weak short wave moving through the ridge which could result in some showers making into the Tri-State on Monday. The ridge will get pinched off as a low tracks east out of the central Plains on Tuesday. This low will get absorbed into another low retrograding across southeast Canada on Wednesday. The large merged low will then pivot eastward Thursday night into Friday. This evolution will lead to several days of wet weather, with some improvement late in the week. In addition, temperatures will be below normal with Thursday looking to be the coolest day with readings 10 degrees or more below normal. && .AVIATION /02Z SATURDAY THROUGH WEDNESDAY/... Scattered thunderstorms will continue to push off to the east over the next few hours. We should then be dry through the remainder of the night with mainly VFR conditions persisting. IN developing CAA on the back side of the cold front, expect gusty west winds in the 25 to 30 knot range during the day on Saturday and allow for sct-bkn VFR cu through the day. Th winds and cu will dissipate as we head into Saturday evening. OUTLOOK...No significant weather expected. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None. IN...None. && SYNOPSIS...
