NWS Wilmington, OH wrote its last area forecast discussion before the first event at May 23, 2:46 PM EST, 1 hour 24 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Wilmington OH 346 PM EDT Thu May 23 2019 .SYNOPSIS... Scattered showers and thunderstorms will be possible this evening as a cold front moves south through the region. The cold front will then stall near the Ohio River by Friday morning. This front will slowly move back to the northeast as a warm front Friday afternoon into Friday night. The upcoming Memorial Day Weekend will be warm and humid with chances for showers and thunderstorms increasing through the period as another cold front slowly moves south toward the region. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... A weak disturbance in the zonal mid level flow aloft will combine with a southward moving cold front to bring scattered showers and thunderstorms to the southern CWFA into this evening. Moderate bulk shear and moderate instability will favor a few storms to become severe with damaging winds and large hail the primary severe weather threats. However, decent low level SRH may allow some storms to rotate, posing an isolated threat for a tornado. As the disturbance moves east later this evening, coverage should wane, and will then only leave a low chance of showers and thunderstorms with the boundary as it settles south of the Ohio River. By late tonight, weak return flow above the western part of the boundary may induce a shower/storm toward morning. Skies will clear north, with skies becoming partly cloudy south. Drier, cooler air will allow temperatures across the north to drop into the mid 50s to the lower 60s. More humid air will linger along and south of the Ohio River where lows will drop into the mid and upper 60s. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/... Another disturbance may ride a slowly building mid level ridge into the Ohio Valley Friday morning. This feature, along with weak return flow up and over former boundary which should be laying west to east near the Ohio River Friday morning, may keep a chance of a shower/storm going across the southern/western CWFA. As the day wears on, we will lose the weak overrunning forcing as the boundary begins to move northeast as a warm front. Chances for showers/storms may wane by late in the day across the west as mixing and weak forcing do not provide a favorable environment for sustained convection. The boundary slicing across the region, highs will vary. They will range from the mid 70s north to the mid 80s southwest. For Friday night, the warm front will slowly move northeast through the remainder of our area. Can not rule out a small chance of a shower/storms (10 percent), but this will result in a dry worded forecast given the small chance. Skies will be partly cloudy. Lows will range from the mid to upper 60s. && .LONG TERM /SATURDAY THROUGH THURSDAY/... Active weather pattern this weekend with a front oscillating through the area. Chances for thunderstorms will continue Saturday around the periphery of the mid level ridge. The best chance looks to be across ILN/s northern counties closer to the frontal boundary. Warm temperatures to continue with high temperatures Saturday from the mid 80s north to the upper 80s south. A better threat for storms continues to be focused on Sunday as the northern portions of the mid level ridge flatten and the surface front sags back south into the Ohio Valley. Sundays high temperatures look to range from near 80 north to the mid/upper 80s south. The mid level ridge builds over the area Monday with the front lifting back north as a warm front, keeping the threat for thunderstorms in the forecast. Generally, expect highs of 80 to 85 on Monday. Model solutions in a little better agreement with the mid level ridge in place and surface front positioned to our north across the southern Great Lakes Tuesday. This should work to limit pcpn chances but can not rule out isold activity in the warm sector. Expect warm readings with Tuesdays highs from the lower/mid 80s north to near 90 far south. Although timing differences exist - regarding mid week frontal passage - models are generally in better agreement with the front coming thru late Wednesday/early Thursday. Moisture and instability increase Wednesday ahead of this front as mid level ridge shifts east and the flow backs. Will allow pops to increase to likely during the day. Temperatures will depend on front/pcpn timing - with highs expected to range from the upper 70s northwest to the upper 80s southeast. Westerly mid level flow develops with initial frontal passage followed by a secondary front. This will keep a low pop chance of a shower or thunderstorm Thursday. Temperatures to turn cooler with Thursdays highs from the mid 70s northwest to 80 southeast. && .AVIATION /20Z THURSDAY THROUGH TUESDAY/... A cold front will move southeast into our region this afternoon and evening. An embedded disturbance in the mid level flow aloft will combine with the advancing front and diurnal instability to bring scattered showers and thunderstorms. Activity is expected to wane this evening. VCTS/CB has been placed at all sites for a period except KDAY. Brief MVFR ceilings and IFR visibilities can be expected with storms. For the overnight period, although the front will eventually lay out west to east along the Ohio River, weak return flow aloft will occur up and over the boundary late. This will bring a low chance of a shower/storm west of KCVG/KLUK late. On Friday, a mid level ridge will slowly build northward into the Ohio Valley. Old frontal boundary will slowly pivot northeast as a warm front during the day. There could be a low chance of a shower/storm across the western forecast area through early afternoon near the advancing boundary. Thereafter, mixing may reduce the weak ascent, allowing convection to wane, despite peak heating.
