...Updated Aviation Discussion...

.SHORT TERM (Now through Saturday Night)...
Issued at 323 PM EDT Fri Sep 23 2016

Overall, not much change in the weather pattern in the near term.
Ridging at the surface and aloft will keep the weather dry and very
warm over the next 36 hours.  A diurnal Cu field will give way to
mostly clear skies tonight with lows in the lower-middle 60s. Highs
Saturday will likely warm into the upper 80s to lower 90s once
again.  Lows Saturday night look to cool into the middle to lower
60s.

.LONG TERM (Sunday through Friday)...
Issued at 252 PM EDT Fri Sep 23 2016

We will have one more hot day on Sunday under the upper level ridge
before a pattern change finally brings cooler weather. Highs on
Sunday will continue to be in the upper 80s to lower 90s with lows
Sunday night in the mid to upper 60s.

From Monday into Tuesday a strong trough will dig into the Lower
Ohio Valley. A cold front will sweep through the region on Monday.
Scattered showers and storms will accompany this front as it swings
through. It looks like the best chance of rain right now will be
Monday afternoon as the front is moving through. Monday`s highs will
be a bit tricky as they will depend on how fast the front moves
through as well as cloud and precipitation coverage.

Much cooler air will begin to build in Monday night. Lows should
drop into the 50s areawide with highs only in the lower to mid 70s
on Tuesday. High pressure will build back in for the remainder of
the week bringing dry weather and slowly warming high temperatures.
The coldest mornings will be Wednesday and Thursday mornings with
some locations dropping into the 40s.

.AVIATION (00Z TAF Update)...
Issued at 700 PM EDT Fri Sep 23 2016

VFR conditions will continue this evening and for the first portion
of the overnight hours. Some fog is expected to develop tonight. The
best chance for fog will be at BWG. Dewpoints there have remained
higher than at other sites and guidance is most pessimistic.
Visibilities could occasionally be reduced below 1 mile. Will also
mention light fog at SDF and LEX towards dawn. After the fog
dissipates tomorrow, winds will be light and variable under mostly
clear to partly cloudy skies.
