AREA FORECAST DISCUSSION National Weather Service Wilmington OH 942 AM EDT Sun Sep 19 2021

SYNOPSIS. High pressure will bring warm and dry conditions to the region today. As the high moves east tonight, return flow from the Gulf of Mexico will bring abundant moisture back to the area. There will be an increasing chance for showers and thunderstorms Monday through Tuesday ahead of an approaching cold front. Behind the front, a much cooler airmass will settle into the region through the second half of the week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. An upper level ridge in place across the upper Ohio Valley this morning will begin to shift off to the northeast this afternoon as short wave energy lifts up across the Tennessee Valley. This will result in an increase in mainly high level clouds from the south through the day. It will be warm again this afternoon with highs generally in the 85 to 90 degree range.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/. High pressure will move east tonight. Return flow on the back side of the high will bring deeper moisture northward from the Gulf of Mexico. An embedded disturbance in the mid level flow, along with a modest low level jet, will bring an increasing chance of showers to western locations during the overnight period. Highest probability will be across the far west. Overall, clouds will increase and thicken. It will be warm with lows only bottoming out in the mid to upper 60s.

Aforementioned disturbance will pivot northward into Michigan on Tuesday. This feature will be followed by some sheared out energy in the mid level flow. These pieces of energy will keep the threat for showers and a few thunderstorms going for western locations. Eastern locations will just see a chance of showers. Although it will be humid, temperatures will be kept down due to clouds and pcpn. Highs will range from the upper 70s to the lower 80s.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/. A decrease in rain chances is expected to occur Monday overnight as scattered shower activity becomes isolated as shortwave energy north of the area moves away. Enough lower level convergence and moisture will be present that storms may linger through the period, but organized activity will not given the position of the cold front staying along a Chicago-St. Louis line by daybreak Tuesday. The front approaches from the northwest Tuesday and activity will see a marked increase through the day. The h7 trough and surface front will be well ahead of the upper level trough. The surface front makes a good progression from the northwestern CWA at midnight to the southeastern CWA before daybreak Wednesday. Stratification of the moisture plumes ahead of the upper low that will be trailing and located along the IL/IN border by daybreak will promote a very potent moisture transport system for prolonged moderate to heavy rainfall over the region.

Cold air rushes in on Wednesday and the upper low positions itself over eastern IN, promoting a cold and continuous rain, and maybe some afternoon embedded thunder in the eastern CWA. Precip ends quickly in the evening though the persistence of some models continuing a chance overnight and into Thursday does appear to put a bit of question into the odds of more shower activity beyond the daytime hours Wednesday.

High pressure settles over the area and return flow sets up as early as Friday, but temperatures will not see any real recoveries as another upper trough is progged to cross Saturday. Model uncertainty increases heading into the end of the period, though the overall pattern supports an eastern U.S. long wave trough and below normal temperatures for the Ohio Valley.

AVIATION /14Z SUNDAY THROUGH THURSDAY/. High pressure at the surface and aloft will extend across the region through today. Some high level clouds will spill across the area from the southwest. Diurnal cumulus clouds are also expected after 16Z. Winds will be from the east/southeast around 5 knots.

For tonight, mid level ridge will move off to the east. Deeper moisture will begin to be lifted northward into the Ohio Valley as low level flow becomes southerly. An embedded mid level disturbance, along with a modest low level jet, will bring a chance of showers to western terminals between 00Z and 12Z. Ceilings should lower but remain VFR. However, a few pockets of MVFR visibilities may occur in heavier showers. Winds will be from the south/southeast around 5 knots.

OUTLOOK . MVFR ceilings, visibilities, and thunderstorms possible Monday and Tuesday. MVFR/IFR ceilings and visibilities likely Tuesday night into Wednesday.
