.Short Term...(Today through Saturday)
Issued at 240 AM EST Fri Nov 24 2017

Mostly sunny skies are expected today with a warm up in temps in
return flow.  Afternoon temps should warm nicely into the mid 50s to
around 60 degrees.

Late tonight a cold front will pass through the region bringing
shallow low level moisture.  There may be just enough moisture and
forcing to produce a few sprinkles as the front passes through
during the overnight hours into Sat morning.  Went ahead and kept
the sprinkle mention in the forecast.  Low temps should hold in the
lower 40s tonight.

For Saturday, expect partly cloudy skies during the morning hours to
become mostly sunny Sat afternoon behind the front.  The cold air
will lag behind the front giving temps the chance to reach the mid
to upper 50s Sat afternoon.

.Long Term...(Saturday night through Thursday)
Issued at 250 AM EST Fri Nov 24 2017

Saturday Night - Tuesday...

Slightly colder air will arrive Sat night/Sun behind the
aforementioned cold front.  Expect highs on Sun to drop back into
the upper 40s/lower 50s.

However, another warm swing in temps will begin by Mon/Tue as upper
ridging builds into the Ohio Valley. Expect highs back into the
lower 60s by Tue!

Wednesday - Thursday...

Forecast confidence remains low regarding the next chance for rain
with a few different disturbances progged to move through during the
latter half of the week.  Most long range models indicate a chance
for rain in the Wed/Thu time frame due to a quick moving upper
shortwave trough.  However models vary on timing by as much as 12-18
hrs still.

Also with the 0Z model runs, a second stronger upper trough is being
progged to quickly move in behind the first potentially prolonging
light rain chances into Fri.   Rainfall amounts vary greatly with
this secondary trough.  Temps should remain near or slightly above
normal Wed/Thu.
