.SHORT TERM (Now through Thursday Night)...
Issued at 250 PM EDT Wed Sep 21 2016

Dry, hot weather continues as a strong upper level ridge continues
to control the region.  As sfc conditions continue to get drier each
day and the ridge continues to strengthen, temps will continue to
climb a little higher.  Most locations will at least reach the upper
80s tomorrow afternoon with more locations hitting 90 or a little

Low temps will continue to creep up as well with lows in the low to
mid 60s expected both tonight and Thu night.

.LONG TERM (Friday through Wednesday)...
Issued at 310 PM EDT Wed Sep 21 2016

Friday - Sunday...

Hot weather continues!  The upper ridge axis will maximize over the
Ohio Valley this weekend which will encourage high temps to reach
the lower 90s over many locations Fri-Sat-Sun.  Lows will remain in
the 60s.  The one relieving factor to this weather pattern will be
the drier air mixing down each afternoon helping conditions feel
a little better.

Monday - Wednesday...

A strong upper low entering the central CONUS Sun will create a very
low confidence forecast for next week.  Long range models vary
greatly on how this feature will oscillate over the central CONUS
next week and when exactly a strong cold front associated with it
will cross the Ohio Valley.  For now will start low POP chances late
Mon, but rain chances look more likely for the Tue-Thu time period.
Although the cold front timing is in question, it is clear that a
good cool down awaits us behind the front by some time mid week next


.AVIATION (00Z TAF Update)...
Issued at 653 PM EDT Wed Sep 21 2016

The large ridge will remain in place through this TAF period
bringing mainly VFR conditions. The exception will be some light fog
at BWG tomorrow morning. Similar to this morning, visibilities may
jump around for a couple of hours ranging from VFR to IFR or lower.
Winds tonight will be light out of the northeast. They will shift to
more easterly or southeasterly tomorrow afternoon.
