000 FXUS61 KILN 241511 AFDILN Area Forecast Discussion National Weather Service Wilmington OH 1111 AM EDT TUE MAY 24 2016 .SYNOPSIS... High pressure will push east across the region through this afternoon, resulting in another sunny and warm day. Above normal temperatures will continue through the weekend as a series of upper level disturbances push through the region. This will bring a chance of showers and thunderstorms from time to time through the end of the week. && .NEAR TERM /UNTIL 6 PM THIS EVENING/...
-- Changed Discussion --
Surface high pressure will remain in place across the region through this afternoon. Outside of a few high level clouds pushing up over the ridge and a few diurnal cumulus, mostly sunny skies are expected. As the airmass continues to modify, expect highs a bit warmer than what we saw on Monday, with highs in the upper 70s to the lower 80s.

&& .SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/... As the surface high moves off to the east tonight into Wednesday, some return flow will develop as the low level southwesterly flow begins to increase. The combination of a weak mid level impulse moving through the lower Ohio Valley and some developing waa could lead to isolated to scattered shower and possibly thunderstorm development off to our southwest later tonight. If this does develop, it will lift northeast toward our area late tonight into early Wednesday morning. Will therefore allow for some lower chance pops to work into our southwest late, but with little if any instability progged across our area, will keep any pcpn as just showers through Wednesday morning. In continued southwesterly low level flow and waa, we should push up into the lower 80s through Wednesday afternoon. This will allow for us to destabilize through the day and with another mid level short wave lifting northwest across the area Wednesday afternoon into Wednesday night, expect scattered shower and thunderstorms to develop. We will destabilize once again through the day on Thursday as we warm back up into the lower 80s. However, with a little bit of mid level ridging possibly redeveloping across the region, think thunderstorm development will be more limited so will keep pops in the lower chance category through Thursday afternoon. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... The H5 ridge continues to build up over the east coast into the weekend. This will lock the summer pattern in for the extended. Highs will be in the lower to mid 80s each day. Scattered diurnal convection will also be the rule. Went with only chance pops each day...tapering off overnight. Low temperatures should be mild through the period, as they will generally be in the 60s. && .AVIATION /15Z TUESDAY THROUGH SATURDAY/... Surface high pressure will be centered southeast of the area today, providing dry conditions and light southwesterly winds. A few fair weather cu will be possible this afternoon, but otherwise SKC conditions expected until a band of cirrus spreads in from the west later this afternoon. A mid-level disturbance may trigger some shower activity over the lower Ohio Valley after 00Z Wednesday that could drift into our area towards daybreak Wednesday. Not overly confident in the rain potential at this time given the limited moisture and forcing, but do expect an increase in low/mid level clouds. OUTLOOK...Thunderstorms possible Wednesday afternoon through Saturday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
