AREA FORECAST DISCUSSION

218 PM EST FRI MAR 7 2014

.SHORT TERM...-- Changed Discussion --(THIS EVENING THROUGH SATURDAY NIGHT)
ISSUED AT 218 PM EST FRI MAR 7 2014

A MID/UPPER LEVEL RIDGE WILL PROGRESS ACROSS THE AREA OVER THE NEXT
24 HOURS...PROVIDING MAINLY CLEAR SKIES INTO TOMORROW. WITH THE RIDGE
POSITIONED OVERHEAD TONIGHT...TEMPERATURES ARE EXPECTED TO PLUMMET
THROUGH THE NIGHT REACHING THE LOWER TO MIDDLE 30S BY MORNING. THE
COLDEST READINGS WILL RESIDE IN THE VALLEYS...WHERE A FEW UPPER 20S
CANNOT BE RULED OUT. WITH DEWPOINTS RUNNING ABOVE 32 AT THE
MOMENT...IT LOOKS LIKE WE COULD SEE SOME POTENTIAL FOR FOG TONIGHT AS
TEMPERATURES DROP THROUGH THE MID AND LOWER 30S. WILL PLAN TO MENTION
FOG MAINLY IN THE VALLEYS. A SHORTWAVE TROUGH WILL THEN PUSH QUICKLY
ACROSS THE AREA SATURDAY NIGHT. THIS SYSTEM WILL NOT HAVE MUCH
MOISTURE TO WORK WITH...ESPECIALLY EARLY...AND MAY BE WEAKENING AS IT
CROSSES THE AREA. THUS...HARD TO GO WITH ANYTHING HIGHER THAN CHANCE
POPS WITH THIS FEATURE. THE NAM REMAINS THE MOST AGGRESSIVE WITH
PRECIPITATION WHILE THE GFS AND ECMWF ARE MUCH WEAKER WITH THE SYSTEM
AND ASSOCIATED PRECIPITATION. WE COULD SEE PRECIPITATION MANIFEST
ITSELF AS MORE OF A DRIZZLE BY LATE SATURDAY NIGHT WITH MOST OF THE
MOISTURE LOCATED ABOVE -5C IN THE COLUMN. WITH CLOUDS AND POSSIBLE
PRECIPITATION...TEMPERATURES WILL BE A BIT MILDER WITH LOWS INTO THE
MID 30S. WE MAY SQUEEZE OUT SOME UPPER 20S IN THE NORTH AS SLIGHTLY
COLDER AIR SPREADS IN BEHIND THE DEPARTING TROUGH.

.LONG TERM...(SUNDAY THROUGH FRIDAY)
ISSUED AT 218 PM EST FRI MAR 7 2014
