NWS Wilmington, OH wrote its last area forecast discussion before the first event at Jul 2, 2:57 PM EST, 31 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Wilmington OH 357 PM EDT Tue Jul 2 2019 .SYNOPSIS... Warm and humid conditions will continue through the holiday week, with a chance for thunderstorms each day. affect the region, bringing the chance of thunderstorms each day. The best chance for more widespread and organized storms will be Wednesday. && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... Convection firing this afternoon as the region sits between an upper ridge to the SW of the forecast area and an eastern Great Lakes shortwave pushing through NE Ohio, and the associated weak frontal boundary. Plenty of instability to work with and DCAPE values from 1-1.3K favoring some storms to contain severe winds. Minimal significant forcing or shear to speak of so gusts will be pulse in nature. Heat indices will remain in the mid- upper 90s for the next several hours. Expecting convection to die down somewhat with loss of daytime instability, diminishing in coverage after 10pm, though isolated storms possible through much of the night, especially in central Ohio. Overnight lows with lingering cloud cover will be near 70 to lower 70s. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/... Similar pattern on Wednesday, though increased low level moisture and the lingering surface boundary serving as a focus again for afternoon convection, an expectation of more widespread storms. With the weak upper level NW flow and very little steering winds, along with the potential for regenerating storms and outflow boundary interaction in increased low level convergence. This will result in an increased risk of heavy rain and isolated flash flooding, in addition to potential for damaging winds. Daytime highs will be slightly lower with increased clouds, with highs in the upper 80s to approaching 90 in some locations. && .LONG TERM /THURSDAY THROUGH MONDAY/... Thursday through Sunday will see a continuation of a summertime pattern with daily chances of showers and thunderstorms. Increased precipitation chances slightly on Thursday and Friday as it looks like there is a little better forcing on those days. As is typical this time of year with this sort of pattern, with storms that develop during this time there will be the potential for some pulse severe. Damaging winds are expected to be the primarily threat. High temperatures will generally be in the middle and upper 80s. Dewpoints are expected to primarily be in the 70s. This combination will lead to heat index values around the middle 90s at times. Although cannot rule out a stray shower or storm beyond Sunday, it looks like there will be a break in the thunderstorm activity for Sunday night into Monday. In addition there will be a brief break with some of the higher dewpoints as well as dewpoints are expected to be in the 60s. && .AVIATION /19Z TUESDAY THROUGH SUNDAY/... Thunderstorms developing across the region, but not expected to be more than isolated in coverage until about 21z-00z. Have brought in a tempo group for KCMH/KLCK in this timeframe, but have otherwise kept VCTS for all other sites. Ceilings and visibilty should still remain VFR, but in thunderstorms MVFR visbilities possible. OUTLOOK...Thunderstorms possible through Saturday, with the activity peaking each afternoon. MVFR visibility possible in thunderstorms. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None. IN...None. && SYNOPSIS...JDR NEAR TERM...JDR SHORT TERM...JDR LONG TERM...Novak AVIATION...JDR
