AREA FORECAST DISCUSSION National Weather Service Wilmington OH 641 AM EDT Sun Jun 13 2021

SYNOPSIS. A weak cold front will pass across the region today offering a chance for thunderstorms into the afternoon. A second threat for showers and thunderstorms will occur Monday afternoon as a cold front moves through the area. Cooler and drier air will then work in for mid week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Strong mid level ridge remains to our west over the Plains and the Rockies -- placing the Ohio Valley in a northwest flow pattern. Shortwave and associated surface cold front to drop south through the Ohio Valley this afternoon. Debris clouds from last evenings convection spilling south through Southern Ohio/Northern Kentucky have kept fog in check.

Scattered showers and thunderstorms will re-develop today in the unstable airmass ahead of the weak cold front as it moves southeast across thru the area today. Lapse rates steepen with SB CAPE values of 2500 to 3000 J/KG. This instability ahead of the cold front will fuel the development of a few strong to severe storms over ILN/s southeast counties. Forecast soundings continue to show some analogs for large hail. Also, DCAPE values approach 1200 J/KG -- which supports the potential for strong to damaging winds. The timing of front moving thru the area will limit the potential for severe weather to ILN/s southeast counties with the threat ending by mid afternoon. Will continue to mention this threat in the HWO product. Expect warm highs in the mid and upper 80s.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/. In the wake of the front some drier air will filter into the region as weak ridging works into the area tonight. This will allow skies to clear. Lows will fall back into the upper 50s to lower 60s.

Mid level shortwave to drop thru the Great Lakes Monday with a surface cold front moving thru the area during the afternoon into early evening. Flow is better with effective shear of 30 to 35 kts. This shear combined with moderate instability could lead to a few strong to severe storms over ILN/s eastern counties. Will mention this threat in the HWO product for portions of Central Ohio.

Highs to range from the lower 80s northwest to the upper 80s southeast.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/. Any lingering pcpn from the s/wv trough will dissipate by late Monday evening. Flow aloft will begin to shift more towards the northwest as the H5 trough over the eastern CONUS becomes more amplified and digs further south into the lower Ohio Valley. Concurrently with the upper trough, surface high pressure will start to build in on Tuesday out of Canada. There is some evidence that without a strong influence of the surface high just yet, our far eastern counties in west-central Ohio down through the lower Scioto Valley could see an isolated shower/storm Tuesday afternoon around the time of peak daytime heating. Dry air advection will limit the overall potential, but introduced a 20% PoP for now.

Tuesday night through Thursday night will offer dry and seasonable conditions as the surface high slides further southeast into the Upper Midwest. Surface dewpoints will take a huge dip back into the upper 40s to lower 50s for Wednesday and Thursday - making for pleasant outdoor conditions. Additionally, many locations will observe highs in the upper 70s, which would be near or just below seasonal norms for this time of year.

Come Friday, an upper-level s/wv trough will eject the surface high pressure eastward and provide the next best opportunity for showers and storms to develop. A series of shortwaves will continue to move through on Saturday and appear to keep chances for showers/storms in the forecast - although not likely as widespread as Friday. This pattern appears to continue for much of the weekend, but high temperatures will at least be near seasonal values.

AVIATION /12Z SUNDAY THROUGH THURSDAY/. Strong mid level ridge remains to our west over the Plains and the Rockies. This places the Ohio Valley in a northwest flow pattern. Shortwave and associated surface cold front to drop south through the Ohio Valley today.

VFR debris clouds from convection last evening has mitigated the development of widespread fog. A brief period of MVFR vsbys at KLUK and KLCK will improve quickly this morning.

Scattered showers and thunderstorms will re-develop today in the unstable airmass ahead of the weak cold front as it moves southeast across the area today. Will mention VCTS at KCVG and KLUK. KILN and KCMH/KLCK into early afternoon. Thunderstorm threat will diminish as drier air filters in from the northwest through the remainder of the afternoon.

Weak surface high pressure will build into the area tonight. Although winds will be light and skies clear, fog should be limited to MVFR toward sunrise at KLUK due to the drier air.

Light southwest winds will shift to the northwest to north at 10 kts or less today.

OUTLOOK. No significant weather expected.
