NWS Wilmington, OH wrote its last area forecast discussion before the first event at Jul 30, 12:42 PM EST, 1 hour 8 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Wilmington OH 142 PM EDT Tue Jul 30 2019 .SYNOPSIS... A cold front will move into the area late today and then slowly cross the region tonight and Wednesday before finally pushing off to the east on Wednesday night. High pressure will build into the Great Lakes for the end of the week into the weekend. && .NEAR TERM /UNTIL MIDNIGHT TONIGHT/... Scattered shower activity with a general uptick in coverage expected this afternoon will see some thunderstorms, but only the stronger cells will be strong enough to lay out this thunder and heavier rainfall. Temperatures haven't been changed for today - within a degree or two of 80 - and this is not indicative of strong enough boundary layer heating to initiate any more than the scattered to isolated thunderstorms we are expecting, and right around the convective temperature of 81. Activity will markedly decrease this late day and evening as the upper forcing moves east and whatever heating is suspended with nightfall. && .SHORT TERM /MIDNIGHT THROUGH 6 PM WEDNESDAY/... Mid level trough across the region will not start to move out until Wednesday. Meanwhile at the surface, a cold front will enter the region from the west at the beginning of the period and take until near the end of the period before exiting out of the eastern counties. Precipitation should diminish through the evening. But additional showers and thunderstorms will develop on Wednesday, particularly in eastern counties. Temperatures will drop into the lower to mid 60s tonight with highs getting back into the lower 80s on Wednesday. && .LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/... A weather system will be exiting the region at the start of the long term time period. The potential for a few thunderstorms across the lower Scioto Valley will come to an end Wednesday night. Although an isolated shower or storm cannot be ruled out, expect generally dry conditions for the remainder of the long term time period. Made only minor adjustments to the blend for temperatures. High temperatures through the long term will mostly be in the 80s and low temperatures will be in the 60s. Increased cloud cover from the blend during the daytime hours as the blend tends to underestimate cu development. && .AVIATION /17Z TUESDAY THROUGH SATURDAY/... Scattered shower activity with isolated thunderstorms this afternoon will become a little more active with insolation and then trail off in the later afternoon and evening. Some clearing tonight may favor the development of some low stratus or at least some fog, particularly south of the Ohio River and in the eastern CWA. Showers and a possible thunderstorm may occur tomorrow afternoon but the coverage of any storms will be less than 10% and will be best amended into the forecast when and if they occur. MVFR vsbys and some possible lower cigs in fog will be possible at most locations towards daybreak given some lingering low level moisture and a good shot of colder air coming in to help stratify the boundary layer. OUTLOOK...No significant weather expected. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None. IN...None. && SYNOPSIS... NEAR TERM...Franks SHORT TERM... LONG TERM...Novak AVIATION...Franks
