NWS Wilmington, OH wrote its last area forecast discussion before the first event at Aug 16, 8:09 AM EST, 4 hours 6 minutes earlier.
Area Forecast Discussion National Weather Service Wilmington OH 909 AM EDT TUE AUG 16 2016 .SYNOPSIS... Low pressure in Michigan will exit the region to the northeast and trail a weak cold front through the Ohio Valley. This front will wash out this evening and then a weak upper level trough will cross the Great Lakes and northern Ohio Valley late Wednesday. Weak high pressure will then settle over the region for the end of the work week in a continued moist airmass. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... Scattered showers are lifting northeast across northern portions of our fa this morning. Once these move out of our area later this morning we may then see a bit of a lull in the pcpn. However, as the frontal boundary off to our northwest sags slowly southeast into our area and we begin to destabilize, expect scattered thunderstorm development through this afternoon along a low level convergence boundary out ahead of the front. Low to mid level shear profiles will remain just strong enough to support a low end severe threat with any stronger storms later this afternoon. Also with PWs up around 2 inches, locally heavy rainfall will be possible yet again. Expect temperatures ranging from the upper 70s northwest to the upper 80s southeast. && .SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/... The cold front washes out this afternoon and is not discernible in the pressure fields after 0z tonight. Any lingering thunderstorms along the remnants of it will die out as daytime heating wanes, but more than one of the models continues to produce thunderstorms along it through the overnight hours. Have not gone with any higher than chance overnight and expect these storms to be waning, but did not remove the threat entirely. While Wednesday will be in a relative lull with a nebulous surface pattern, some storms may still be present in the southeast with drier air pushing in from the northwest through the day. Overnight Wednesday into Thursday has just a slight chance of storms over the region given weak flow and a somewhat favorable moisture profile that could pop an isolated shower or thunderstorm. Tuesday night lows will range from the upper 60s in the northwest to the lower 70s in the south. Wednesday highs will range from 80-85 under cloudy skies and overnight lows will dip to the upper 60s. Thursday will see readings a degree or two warmer than Wednesday in a somewhat drier airmass and a little less cloud cover. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... Although can not rule out an isolated thunderstorm, have opted to keep Friday dry with mid level ridge building over the region ahead of long wave trof. Better threat for showers and thunderstorms returns Saturday as long wave trof and associated surface cold front approach from the west. Have continued high chance pops late Saturday/early Sunday with the passage of a cold front. Surface high pressure to build in early next week, providing dry weather and cooler temperatures. && .AVIATION /12Z TUESDAY THROUGH SATURDAY/... Scattered light showers continue to work up through srn IN into wrn OH early this morning, bringing some very light VFR shra to KDAY. SHRA will become more widespread and will move into the wrn tafs later this morning as a sfc low lifts ne, pulling a weak cdfnt into the tafs. With the heating of the day the shra should transition to tsra by afternoon due to the building instability in the very moist airmass. It looks like there will be enuf coverage in the afternoon to add a tempo group to the wrn tafs to cover mvfr conditions in the pcpn. Right now wasn't confident enuf to add a tempo group to the ern tafs. South winds will pick up during the mid morning hours with gusts in the 20 to 25 knot range. Convection coverage will begin to decrease around 00Z with the loss of heating. MVFR cig development is expected aft 00Z. OUTLOOK...MVFR/IFR conditions possible Tuesday night into Wednesday morning. Thunderstorms possible Tuesday night into Wednesday evening, and then again on Saturday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
