NWS Wilmington, OH wrote its last area forecast discussion before the first event at Jul 11, 2:29 PM EST, 2 hours 23 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Wilmington OH 329 PM EDT Sat Jul 11 2020 .SYNOPSIS... Chances for showers and thunderstorms will increase tonight into Sunday as a low pressure system and cold front move into the region. High pressure will then build into the Ohio Valley by Monday, bringing a return to dry weather. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... A weak embedded disturbance in the northwest flow aloft will ripple southeast into the region this evening/early morning. CAMs have been mixed on how widespread convection will become to our northwest before it shows some weakening as it moves away from the better instability advecting east ahead of it. For now, have allowed for a chance of thunderstorms, mainly for the Tri-State region this evening/early morning. SPC SWODY1 has placed this area in a Marginal Risk for an isolated severe storm. Have updated the HWO to indicate this threat. For the remainder of the overnight hours, models are muddled on how much additional convection will develop well ahead of the next short wave/cold front to our northwest. As a result, believe a broad brush approach is the way to go until models can latch on better forcing mechanisms to indicate higher confidence in PoPs. Lows will fall into the lower to mid 60s. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/... A stronger short wave in the northwest flow aloft will accompany weak low pressure and a cold front on Sunday to bring an increasing chance of showers and thunderstorms. Best coverage should coincide with the mid to late afternoon hours as moderate instability develops. As a result, could see a few strong perhaps severe storms. Damaging winds will be the main threat with perhaps some isolated large hail across the southern half of the CWFA. Highs will be mainly in the lower 80s. For Sunday night, the entire weather system will push east/southeast, allowing pcpn to taper off from northwest to southeast. Drier air will then filter into the region overnight. Lows will generally bottom out in the lower 60s. && .LONG TERM /MONDAY THROUGH SATURDAY/... High pressure will be in place for Monday and move east of the forecast area for Tuesday. With northerly flow, expect Monday to be the coolest of the long term with high temperatures ranging from the upper 70s to the middle 80s. High temperatures on Tuesday will be near normal in the low to middle 80s with continued dry conditions. The heat and humidity will begin to build for Wednesday and the remainder of the week. Multiple systems will move through during this time allowing for daily thunderstorm chances. Heat index values across at least a portion of the area are expected to reach into the middle to upper 90s beginning on Wednesday. There will be the potential late week for some heat index values to reach near 100. Due to uncertainty in exact thunderstorm timing this far out and the impact on temperatures, decided to hold off on heat mention in the HWO at this time. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... Scattered cumulus clouds will prevail the rest of the afternoon. Winds will be from the west/northwest between 10 and 15 knots with some gusts in the lower 20 knots. For tonight, a weak embedded disturbance in the northwest flow aloft will ripple southeast into the region. This feature will at least bring a chance of thunderstorms, mainly toward the KCVG/KLUK during the evening hours/early morning hours. Have placed a VCTS/CB at these terminals. Otherwise, models are muddled on additional convection once this first disturbance ripples by. Have broad brushed the terminals with VCSH. There is some indication of MVFR ceilings developing across the west toward morning. Have went ahead and placed some MVFR ceilings at KDAY where confidence is the highest. On Sunday, a more robust disturbance will rotate southeast into the Ohio Valley. This will be associated with a weak cold front. The best dynamics appear poised across the southern half of the CWFA where showers and thunderstorms should become numerous during the afternoon hours. Aviators can expect at least MVFR conditions with thunderstorms with possible brief pockets of IFR visibilities in heavier rainfall. OUTLOOK...Thunderstorms to linger into Sunday evening. Thunderstorms possible Wednesday night into Thursday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
