Area Forecast Discussion...UPDATED
National Weather Service Peachtree City GA
930 AM EST Mon Dec 11 2017

No changes to the forecast for today. Increased the winds some
for Tuesday due to a rather strong pressure gradient with the
next cold front.



PREV DISCUSSION... /Issued 637 AM EST Mon Dec 11 2017/ 

SHORT TERM /Today through Tuesday/...

Cool and dry conditions will continue through the short term. Weak 
high pressure over the state will give way to a dry cold front 
expected to move through the area Tuesday. For now we are still only 
expecting increased cloud cover with this frontal passage but the 
models continue to show deeper moisture increasing across north GA 
with every run. The models still keep the better moisture well north 
of the region but will continue to keep a close eye on how this next 
system develops over the next 24 hours. The good news with this 
frontal passage is it moves through the state during the day time 
hours Tuesday so if we do get any precip from will be mainly 
in the form of rain. 

As for temps they will stay on the cool side with highs in the 40s 
and 50s and lows mainly in the 30s.


LONG TERM /Tuesday Night through Sunday/...

No significant changes through the extended forecast period from
previous forecast trends. Medium-range models continue to be in 
fairly good agreement through the period. Two mainly dry short waves
and associated cold fronts sweep through the region during the
workweek. Cold start to the period Tuesday night/Wednesday behind 
the first system. Models indicate temperatures should rebound 
quickly heading into the end of the workweek ahead of the next system
Friday. Marginal moisture available with this late week system, and 
mainly confined to the southern and eastern portions of the forecast 

Much more vigorous system moves in at the end of the period. Much
warmer and more moist air mass sweeps into the region with this
system bringing much better chances for precipitation and minimizing
any chances for wintry precipitation types. 



12Z Update...
VFR ceilings with no precipitation or restrictions to VSBYS
expected. Winds will stay out of the W to SW at 10kt or less
today and tonight. As winds shift to the NW by 12z Tuesday wind 
speeds will increase into the 10-15kt range gusting to 25kt 
through 18z Tue. 

//ATL Confidence...12Z Update...
High confidence on all elements.
