the forecast calls for a cold but dry weekend. The chance for 
rain returns to the forecast Monday night and continues through 
the rest of the week. Temperatures will begin to warm up 


Near term /through Sunday/... 
made minor adjustments to the sky cover and dewpoint grids for 
this update. Upper level clouds over the southern portion of 
the County Warning Area have some density to them. Upper level moisture will 
continue to advect into the region in west-northwest flow aloft into the 
evening, but drier air in the mid levels is arriving as well as 
surface pressure rises. This will continue to help to suppress 
thicker clouds and precipitation to the south as low pressure 
crosses the Tennessee Valley. The forecast remains dry locally. 
Overnight lows will be similar to last night's values. Sunday 
should be mostly sunny with only some passing high clouds. 
Despite sunshine, winds out of the east and north will keep 
temperatures below normal, near today's values. 


Short term /Sunday night through Tuesday/... 
surface high pressure will continue to build across the eastern 
Great Lakes along with an upper level ridge. This should allow 
dry conditions to persist into Monday evening before 
precipitation spreads east from low pressure over the plains. 
Have slightly expanded likely pops Monday night into Tuesday. 
Models are hinting at the possibility that some locations could 
have precipitation begin as freezing rain thanks to some warmer 
air aloft. However, the period of freezing rain potential looks 
to be limited with highs expected to climb into the upper 40s 
and lower 50s in most locations. 


Long term /Tuesday night through Saturday/... 
there was little change to the extended forecast, with a slow 
moving cold front still dominating the extended forecast. Most 
locations should receive rain Tuesday night into Wednesday 
before differing model solutions result in only chance pops in 
the forecast. The chance of showers will linger all the way into 
Friday night before the front pushes out to the Atlantic Ocean. 
Temperatures will warm towards seasonal norms, meaning that most 
precipitation should fall as rain, even at night. 


Aviation /00z Sunday through Thursday/... 
VFR conditions are expected through the forecast period. 
Expansive high clouds this evening will give way to clearing 
from the north Sunday. Light northerly surface flow will 
gradually veer to easterly and increase through Sunday. 

the next chance of general restrictions may arrive by Tuesday 
with a cold front.
