NWS Wilmington, OH wrote its last area forecast discussion before the first event at Jul 20, 7:21 PM EST, 2 hours 26 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Wilmington OH 821 PM EDT Wed Jul 20 2022 .SYNOPSIS... Hot and humid conditions persist this evening ahead of a weak cold front. Showers and thunderstorms are possible late this afternoon and evening ahead of the cold front with some strong storms possible. Hot and dry weather returns for the second half of the work week before rain chances return this weekend. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... Strong instability with ML CAPE values of 2500-3500 J/kg has developed in the warm airmass late afternoon into early evening. A weak CAP and lack of forcing has inhibited convective thru most of the day. Main mid level short wave is passing through the Great Lakes. As mid level height falls push across the area and a weak region of pre-frontal confluence drops across the area expect widely scattered to scattered storms to develop. A few of the storms could support strong to damaging wind gusts thru the evening. The best chance for storms will be across Central Ohio thru about 10 pm. The storms threat ends by midnight tonight after the weak front pushes thru the area. With the loss of heating heat indices will beginning to drop below 100. Therefore, the heat advisory has been allowed to expire. Although conditions will slowly improve, hot and muggy conditions will persist thru most of the evening. Although the weak front moves thru the area temperatures don't drop much behind the boundary with winds shifting toward westerly. Forecast lows are in the upper 60s to around 70. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/... The Ohio Valley will be in between weather systems for Thursday and Thursday night. Low pressure remains off in eastern Canada and high pressure stays anchored off the southeast coast. Hot dry conditions persist. Forecast highs are in the upper 80s and forecast lows are in the upper 60s under partly cloudy skies. Westerly winds around 10-15 mph on Thursday relax to around 5 knots out of the southwest Thursday night. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... Sub tropical ridge to extend from the Southern Plains across the Gulf states with a west-northwest flow across the Ohio Valley and Great Lakes. This will act to keep the active MCS track a bit north of the area at the end of the week. Expect above normal temperatures with highs in the upper to lower 90s on Friday. A weak embedded mid level shortwave may lead to a few showers or thunderstorms across the far north Saturday. Confidence is low on this precipitation potential Saturday with the most favored chance north of ILN/s area. Otherwise...expect hot and dry conditions with highs of 90 to 95 Saturday. Mid level trough to settle south into the Great Lakes late this weekend into early next week. This will allow a frontal system to drop south and stall out across the area. Precipitation chances will begin to increase Sunday -- as the front slips south into the area. With the front stalling across the Ohio Valley, this will keep a chance of thunderstorms in the forecast -- with the best chance across the south Monday and Tuesday. On the warm side of the front, highs to range from the upper 80s north to the middle 90s south Sunday. Temperatures to drop back closer to normal with highs Monday and Tuesday ranging from the lower 80s north to the upper 80s south. With the westerlies settling south into the Ohio Valley, models indicating the development of a surface wave along this boundary. Expected model solution differences on strength, timing and location exist at this time frame but this low should enhance shower and thunderstorm chances Wednesday. && .AVIATION /00Z THURSDAY THROUGH MONDAY/... Strong instability with ML CAPE values of 2500-3500 J/kg has developed in the warm airmass this afternoon. A weak CAP and lack of forcing has inhibited convective development. As a weak region of pre-frontal confluence pushes across the TAFs early this evening expect widely scattered to scattered thunderstorms to develop. A few of the storms could support strong wind gusts. Also, a brief reduction to IFR conditions are possible in a storm. Due to limited coverage of storms have only mentioned VCTS at this time. Weak front pushes east across the TAF sites later this evening and shower/storm chances end behind the front. VFR conditions to persist overnight into Thursday. The exception is KLUK valley where fog is possible toward sunrise. Southwesterly winds around 10 kts shift to westerly after FROPA tonight and relax to 5-10 knots through 1800z Thursday. OUTLOOK...Thunderstorms will be possible Sunday into Sunday night. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
