.PREV DISCUSSION... /Issued 1036 PM EST Wed Dec 13 2017/ 

Forecast is on track with no major changes needed this late


PREV DISCUSSION... /Issued 304 PM EST Wed Dec 13 2017/ 

SHORT TERM /Tonight through Thursday Night/...

No forecast hazards or chc for precip expected in the short term 
period. 12Z model guidance and adjacent office forecasts in good 
agreement today.

Temperatures in the near term this afternoon about on track but 
dewpoint temps several degrees below forecast likely due to deep 
mixing. Humidity quite low and near fire weather criteria but with 
cool temps and winds less than 10kts have held off on issuing any 

High clouds should increase Thurs night but any chc for precip will 
hold off until Friday, if it were to occur. Temps should remain near 
normal with slightly above normal daytime temps.


LONG TERM /Friday through Wednesday/...

Latest model runs do not warrant adjusting much in the way of the
previously thought pops/weather. There continues to be rather
large discrepancies between the GFS and Euro for early next week
with the evolution of the upper trough energy and interacting
moisture field. The GFS continues to be a much less progressive
solution. Still potential for a thunderstorm threat Monday to
parts of the south given a nose of potential instability in a
highly sheared environment so will watch with future updates.
Previous discussion follows...


PREV DISCUSSION... /Issued 330 AM EST Wed Dec 13 2017/ 

LONG TERM /Thursday Night through Tuesday/...

No significant changes made to the long-term forecast trends.
Medium-range models remain somewhat static in the large scale pattern
but fairly progressive concerning the smaller-scale features through
the majority of the period. Also continue to see fairly good
agreement between models through the beginning of next week. Some
divergence as we head into the middle of next week. All-in-all,
period starts out cool but dry. Short wave sweeps through Friday, but
better moisture and precipitation remains generally south of the
forecast area. Shift to a persistent southwesterly upper flow pattern
over the weekend brings in a milder and wetter period by Sunday
through late Monday, tapering off some as we head into the middle of
next week. 



06Z Update...
VFR Ceilings...No precip...No restrictions to VSBYs expected again
today. Winds will stay out of the West to Northwest at 10kt or
