AREA FORECAST DISCUSSION National Weather Service Wilmington OH 135 PM EDT Thu Sep 16 2021

SYNOPSIS. High pressure will extend across the eastern Great Lakes today. The high will move east tonight while a weak frontal boundary pushes into the western Great Lakes. This frontal boundary will then move farther east and southeast across the remainder of the Great Lakes Friday into Saturday. High pressure will establish itself over the region for the second half of the weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Surface analysis this morning depicts the center of high pressure across the eastern Great Lakes, while a surface boundary weakens to the southeast.

Have allowed dense fog advisory to expire as planned as fog is dissipating and visibilities are improving. Moisture should then eventually manifest itself as a scattered, locally broken, cumulus deck by the early to mid afternoon hours. Temperatures will be near seasonal normals in the upper 70s to the lower 80s.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/. The center of high pressure will move off to the northeast tonight while a weak frontal boundary begins to push east into the western Great Lakes. Skies for the most part should be mostly clear, although there are some signals of potential cloud development late as a weak return flow ensues. Lows will range from the lower to mid 60s.

On Friday, the weak frontal boundary will continue to make its way east/southeast into the Great Lakes while weak mid level ridging occurs across the Ohio Valley. Weak return flow out ahead of the front will bring an increase in pwats to the region. This deeper moisture will combine with diurnal heating to bring a low chance of a pop up shower/storm from mid to late afternoon. It will be warm and humid with highs in the lower to mid 80s.

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/. A surface front will approach the region from the northwest and dissipate when it does reach the area. Scattered to isolated showers may see enough instability from diurnal heating to keep a thunderstorm sparked in the early evening. These showers will be hit and miss through the overnight and into Saturday as mid level shortwave energy crosses, weakening later Saturday as an upper ridge builds over the Ohio Valley. This ridge will hold sway until upper low pressure energy over arklatex gets shunted northeast into the region late Sunday and moreso Monday. Primarily showers are expected but some insolation may permit some cores to support thunder in the later part of the day. Being this far out, do not have thunder in the forecast but do not doubt the possibility. This lingering upper energy and a continued southerly feed of moisture will necessitate the inclusion of showers through Wednesday, ending overnight from west to east, likely earlier than later for a dry Thursday.

Temperatures do not show large potential swings until Wednesday and overnight. Until then, expect highs in the mid 80s to begin dropping to the lower 80s Tuesday, near 80 Wednesday, and upper 70s Thursday. Overnight lows should be fairly static in the low to mid 60s until Wednesday night when some upper 50s get thrown into the mix and then prevail on Thursday night.

AVIATION /18Z THURSDAY THROUGH TUESDAY/. Low clouds that have been slow to dissipate are lingering at ILN and LCK, while remainder of sites have become VFR. Once MVFR ceilings lift at ILN and LCK, VFR should persist through the evening and into tonight, until BR reduces visibilities later tonight under clear and calm conditions. VFR returns Friday morning. Isolated thunderstorms may not impact TAF sites on Friday afternoon.

OUTLOOK . No significant weather expected.
