.Forecast Update...
Issued at 840 AM EST Wed Nov 22 2017

Have a patch of upper-level clouds at about 300 mb, just ahead of a
short-wave at that level. Bumped up sky cover for the next several
hours as that disturbance crosses the region. Otherwise, a good
holiday weekend travel day is in store for today.

.Short Term...(Today through Thursday)
Issued at 215 AM EST Wed Nov 22 2017

Breezy conditions were accompanying the cold front passing through
the region early this morning.  With the front just past the area
now, will see NW wind gusts diminish toward sunrise.

While a few clouds may linger this morning, most of the day will be
sunny.  The colder airmass ushered in by the overnight cold front
passage will pull high temps back into the low to mid 40s today.

Sfc high pressure will be in place tonight and for Thanksgiving Day
resulting in dry conditions and mostly clear skies.  Temps should
drop off quite a bit tonight under good rad cooling with lows
ranging through the 20s.  As we enter return flow Thanksgiving Day,
temps should warm some back into the mid 40s to around 50 for highs.

.Long Term...(Thursday night through Tuesday)
Issued at 215 AM EST Wed Nov 22 2017

Friday - Saturday...

Friday continues to look sunny and warmer.  High temps will range
through the 50s.  Fri night into Sat morning a cold front will pass
through the region bringing a slight chance for a sprinkle or shower
over southeast IN/northern Bluegrass in KY.  However, the model
consensus remains dry so will keep the forecast dry as well.

Saturday will be partly cloudy especially during the morning hours
closer to the frontal passage.  The cold air behind the front will
lag behind quite a bit so Saturday`s high temps still look to range
through the 50s.

Sunday - Tuesday...

The cold air behind the Sat morning front will finally arrive early
Sun resulting in a chilly start in the upper 20s/lower 30s.  Highs
on Sun will fall back into the 40s.

Continued dry weather looks likely for the start of the work week as
sfc high pressure moves through Mon and then return flow starts
again Tues.  Temps will be on a warming trend through mid week ahead
of a deep low pressure system and strong cold front that could bring
showers/storms to the Ohio Valley by mid week.

.Aviation...(18Z TAF Issuance)
Issued at 1233 PM EST Wed Nov 22 2017

VFR is forecast for this TAF period as high pressure controls the
region. A steady, but light, north wind will prevail today with just
a few upper clouds and a few afternoon cumulus possible. Otherwise,
winds will go calm or light and variable tonight, with a light S
wind taking hold on Thanksgiving Day.
