NWS Wilmington, OH wrote its last area forecast discussion before the first event at May 26, 12:35 PM EST, 18 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Wilmington OH 135 PM EDT Sun May 26 2024 .SYNOPSIS... At least two rounds of showers and thunderstorms are expected across the region today into tonight as embedded mid level disturbances interact with an increasingly moist and unstable airmass ahead of low pressure and a cold front. That low pressure system and cold front will move across the Great Lakes and Ohio Valley on Monday, continuing a chance of showers and thunderstorms. A cooler airmass will then settle into the Great Lakes and Ohio Valley through mid week. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... For today, convective complexes extending from Illinois to Kentucky this morning were being aided by a mid level s/wv. These complexes will also likely result in the formation of one or more MCVs. The s/wv and MCVs are forecast to eject east into the middle Ohio Valley by this afternoon. Based on latest radar and model data, this estimated timing appears to be relatively accurate. This energy will couple with an advancing warm front which will bring a plume of MLCAPE values of 1000 to 1500 J/kg, occurring within a moderately sheared environment. As a result, various convection allowing models develop some type of MCS which will progress east/northeast through the area during the afternoon. Given shear and instability, some strong to severe storms will be possible with damaging wind and large hail being the main severe weather threats, although a spin up tornado can not be ruled out given the shear environment. Have gone with categorical PoPs. It appears that once this system moves through, there will likely be a period where pcpn chances will decrease substantially in the wake of this system, along with bringing a temporary decrease in overall instability due to rain cooled air and weak subsidence. Will talk about this more in the short term discussion. It will be humid with highs in the upper 70s to the lower 80s under a low level southerly flow pattern. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/... Models continue to advertise a secondary mid level s/wv moving into the region tonight. This feature will be associated with a stronger low level jet and stronger wind fields. The key to CAMs developing another MCS across the region will be how much of the area can recover with SB/MLCAPES to result in severe weather versus more convection that is elevated/decoupled from the surface. Right now, it appears that our southern/southwestern CWA will have the best chance to at least recover with some SB/MLCAPEs as thunderstorms develop in the low level convergent flow. As storms begin to share cold pools, the system will be pushed forward east/southeast with the 0-3 km shear vector. Damaging winds would be the main threat with isolated large hail, as well as isolated/few tornadoes possible on on individual bowing segments. Again have gone with likely to categorical PoPs. The airmass will be the most moist tonight with pwats in the 1.50 to 2.00 inch range. Thus, very heavy rain may fall in a short period of time which would pose a flood/flash flood threat. However, this should be limited if storms move at a steady pace. Will mention all hazards for today and tonight in the HWO. Pcpn is expected to taper off/diminish in area coverage late as the complex moves east/southeast. Lows tonight will fall into the lower to mid 60s. On Monday, a mean mid level trough will dig east into the Great Lakes and Ohio Valley. This will push surface low pressure and a cold front east through the region. Overall forcing appears weak with the best forcing occurring over the eastern half which is when the cold front will interact with some diurnal heating/instability. It will be locally breezy with highs ranging from the lower 70s northwest to the mid/upper 70s east. && .LONG TERM /MONDAY NIGHT THROUGH SUNDAY/... A couple of upper level disturbances will keep precipitation in the forecast at times from Monday night through the day on Wednesday. Dry conditions are then expected from Wednesday night through the day on Saturday. Saturday night the next chance for precipitation will occur. With the passage of the cold front prior to the long term time period, temperatures will be cooler. High temperatures in the 60s and 70s are expected with lows in the 40s and 50s. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... Aviation will be impacted this afternoon by a line of strong to severe thunderstorms. Gusts over 40 knots are likely at most sites, with visibilities down to IFR and ceilings MVFR. The duration of the will be around 1 to 2 hours at each TAF site, arriving at CVG and LUK near 18z, DAY and ILN 19z, reaching CMH and LCK around 21Z. A lull in thunderstorms is forecast for late this afternoon. Additional thunderstorms are forecast for this evening, though strength may be diminished compared to the initial round. Later tonight as storms diminish again, MVFR ceilings are expected to develop as the lower atmosphere approaches saturation. VFR is likely to return to CVG LUK DAY and ILN by 18z Monday. OUTLOOK...MVFR conditions possible Tuesday afternoon into Tuesday night. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
