Local Area Aviation Weather Discussion

.AVIATION /03Z WEDNESDAY THROUGH SUNDAY/...
As of 800 PM Tuesday...

A brief interlude from thunderstorm activity opens up the TAF
period this evening. A weakened line of showers sailed through
the airspace not too long ago and the next line of potential
strong to severe thunderstorms still remains over a hundred
miles from the western extent of our forecast territory.
Estimated time of arrival for these storms appears to be
sometime after 2Z/3Z and will once again move through in a west
to east direction, bringing with it the possibility of damaging
wind gusts, hail, and a non-zero risk for tornadoes. Tailored
the forecast using tempos through late tonight to account for
post-sunset storms dashing overhead. 

In the wake of convection tonight, light showers and low stratus
will infiltrate the area, resulting in MVFR or worse flight
restrictions into the overnight hours. Should begin to see
improvements across the Ohio River Valley as a low pressure
system ventures eastward and a cold front undergoes an overhead
passage through the area. However, one last round of afternoon
thunderstorms aided by the boundary could be plausible for our
eastern terminals Wednesday afternoon. Opted to include VCTS at
EKN, CKB, and BKW for that reason.

Outside of strong thunderstorm winds, surface flow is
anticipated to be light out of the south/southeast this evening.
Winds begin to shift more southwesterly on Wednesday ahead of
FROPA, and could become breezy during the afternoon and evening
hours.
