AREA FORECAST DISCUSSION National Weather Service Wilmington OH 417 PM EDT Thu Jul 29 2021

SYNOPSIS. Strong to severe thunderstorms possible through late evening Thursday. Cold front swings through tonight, providing cooler and drier into Friday and Saturday. A slight chance for showers exists Sunday, but an extended period of below average temperatures is expected into the beginning of the next work week.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/. A severe thunderstorm watch has been issued for all of our counties with the exception of our northern three (Hardin, Auglaize and Mercer) until 10 PM EDT. A cluster of storms tracking southeast through western Ohio and central Ohio have already produced a number of severe reports - mainly for hail greater than 1" in diameter. While strong, damaging winds and large hail will continue to be the primary threat, several supercells have formed and will keep the threat for isolated tornadoes present with these storms. Additionally, some storms have begun training in central Ohio, which may lead to localized flooding issues.

More favorable 0-6km effective shear remains across our eastern counties in central Ohio where closer to 40 kts is present. These values drop off to near 25 kts towards our western counties. SPC mesoanalysis shows MLCAPE near 2000 J/kg where these storms are located in west-central Ohio. A very moist and unstable environment will remain in place through the evening, keeping strong to severe thunderstorms present for the time being. Our northern counties in central Ohio will have the severe threat end by this evening as storms push further south over the next couple of hours. After about 10pm, the severe threat will begin to diminish, with only some scattered showers possible overnight as the cold front swings through. There could be some river fog development as well - especially further south towards the Ohio River where the moisture will remain higher the longest.

SHORT TERM /6 AM FRIDAY MORNING THROUGH 6 PM FRIDAY/. Drier air filters in on Friday as northwesterly flow persists aloft and surface winds shift out of the north. Some post- frontal stratus clouds will linger during the early morning hours before lifting. Still expecting scattered cu development during the day with weak instability present, but surface high pressure building in from the upper Midwest will offer drier conditions across the fa. Additionally, a relief from the heat and humidity will be felt as dewpoints drop to near or just below 60 (compared to low to mid-70s on Thursday) with high temperatures topping off in the middle 70s to lower 80s.

LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/. Surface high pressure will be across the region on Saturday. Under a northwest flow aloft, a disturbance will pass by to our southwest. It looks like pcpn with this system will stay mostly out of our area, so we are expecting dry conditions. Highs will range from 75 to 80.

A broad mid level trough will dig southeast across the Great Lakes Saturday night into Sunday. This will push a weak cold front east through the area, bringing a low chance for a shower or thunderstorm. It will remain a little cool for the beginning of August.

For the reminder of the forecast, Monday through Thursday, broad mid level troughing will remain with weak high pressure across the Ohio Valley at the surface. It should stay mainly dry through the period with very low chances of pcpn perhaps by late in the week. It will continue a little below normal early week, then closer to normal later in the week.

AVIATION /20Z THURSDAY THROUGH TUESDAY/. Scattered storms expected to develop this afternoon and linger into the late evening hours. Some of these storms will be strong to severe. Have included a tempo group at every taf site to indicate potential timing of TSRA based on latest model guidance. Heavy downpours will lead to reduced vsbys and some MVFR CIG reductions - IFR reductions are less likely but could happen briefly in stronger storms. Strong wind gusts and large hail will be the primary threats with these storms. Included an increase in wind gusts to near 25 kts in the tempo group, but will monitor trends and amend if stronger gusts are expected with thunderstorms.

Thunderstorm threat diminishes this evening from north to south, but a few storms could linger until about midnight for our southern taf sites. Afterwards, a number of sites will observe MVFR CIG and vsby reductions overnight with the passing cold front. Surface winds will shift towards the north-northwest, but remain fairly light below 10 kts overnight.

May have held onto MVFR CIGs longer than needed, but CIG improvement to VFR is expected around sunrise on Friday. Prevailing VFR expected the remainder of the taf period on Friday with light northerly winds.

OUTLOOK. MVFR ceilings and visibilities are possible Saturday night into Sunday.
