325 AM EST SUN DEC 6 2009

.SHORT TERM (TODAY AND TONIGHT)...
A FEW CLOUDS ARE HANGING IN OVER THE EXTREME NORTHEAST PORTIONS OF 
THE CWA THIS MORNING...BUT SHOULD BE GONE BY SUNRISE. EXPECT THAT 
FOG WILL DEVELOP NEAR AREA LAKES THAT ARE STILL RELATIVELY 
WARM...BUT DO NOT THINK IT WILL BE WIDESPREAD ENOUGH TO MENTION. 
WITH TEMPERATURES WELL INTO THE 20S AND SOME AREAS WITH WET 
GROUND...BLACK ICE WILL BE A POSSIBILITY THIS MORNING. WILL CONTINUE 
THE SPS TO ADDRESS THIS. THE AIR MASS OVER THE REGION WILL REMAIN 
DRY THROUGH TONIGHT. THERE IS A WEAK UPPER LEVEL SHORTWAVE TROUGH 
THAT PASSES BY TONIGHT...BUT THIS SHOULD JUST BRING SOME HIGH CLOUDS.

.LONG TERM (MONDAY THROUGH SATURDAY)...A WEAK FRONT TRACKS THROUGH 
THE AREA ON MONDAY. MOISTURE IS LIMITED SO KEPT ONLY SLIGHT CHANCE 
POPS FOR MONDAY. ANOTHER FRONT ENTERS THE REGION ON TUESDAY AND 
LINGERS INTO WEDNESDAY. WITH DECENT MOISTURE ADVERTISED...WILL KEEP 
LIKELY POPS FOR TUESDAY NIGHT AND CHANCE FOR WEDNESDAY. MODELS 
INDICATING PRECIPITATION SHOULD BE ALL LIQUID NOW ON BOTH TUESDAY 
NIGHT AND WEDNESDAY. WITH COLDER AIR FILTERING BEHIND THE 
FRONT...MAY STILL SEE SNOW DEVELOPING ON WEDNESDAY NIGHT WITH THE 
BEST CHANCE FOR ACCUMULATION ACROSS THE HIGHER ELEVATION. HIGH 
PRESSURE RETURNS BRINGING DRY WEATHER FOR THURSDAY. ANOTHER FRONT 
MOVES INTO THE REGION ON FRIDAY NIGHT AND SATURDAY. WITH STILL 
UNCERTAINTY ON TIMING...WILL KEEP ONLY SLIGHT CHANCE POPS GOING FOR 
NOW. STAYED NEAR MEX/HPC GUIDANCE FOR TEMPERATURES.
