.SYNOPSIS...
PRECIPITATION WILL END THIS EVENING AS A COLD FRONT MOVES ACROSS
THE REGION. WINDS WILL GUST OVER 40 MPH IN MOST LOCATIONS EARLY
TONIGHT WITH GUSTS OF 50 TO 55 MPH IN THE RIDGES. EXPECT CALM
WEATHER FOR CHRISTMAS DAY BEFORE RAIN MOVES BACK IN FOR FRIDAY AND
SATURDAY.

&&

.NEAR TERM /THROUGH THURSDAY/...
FORECAST UPDATE FOR ISSUANCE OF A WIND ADVISORY FOR INDIANA,
WESTMORELAND AND FAYETTE COUNTIES IN PA, PRESTON AND TUCKER COUNTIES
IN WV AND GARRETT COUNTY IN MD FROM 9 PM THIS EVENING TO 5 AM
THURSDAY. REST OF FORECAST UNCHANGED AT THIS TIME.

ALTHOUGH TEMPERATURES WERE VERY STUBBORN TO RISE
IN SOME LOCATIONS THIS MORNING...ALL LOCATIONS ARE NOW WELL ABOVE
FREEZING. RAINFALL SHOULD COME TO AN END DURING THE EVENING AS THE
COLD FRONT SWEEPS THROUGH THE AREA...WITH SOME LOCATIONS NORTH OF
I-80 RECEIVING UP TO AN INCH OF SNOW AT THE END OF THE STORM.
ALTHOUGH THERE HAVE NOT BEEN MANY WIND GUSTS ABOVE 30 MPH ACROSS
OHIO...MODELS INDICATE THAT AS THE COLD FRONT PASSES...THERE
SHOULD BE A BRIEF PERIOD OF STRONG GUSTS CWA WIDE. ALTHOUGH AN
ISOLATED LOCATION IN THE HIGHER TERRAIN MIGHT SEE GUSTS TO WIND
ADVISORY CRITERIA...FEEL THAT GUSTS AT 30 MPH IN MOST PLACES AND
40 MPH IN THE HIGHER TERRAIN SHOULD BE SUFFICIENT. THERE SHOULD AT
LEAST BE SOME PARTIAL CLEARING TONIGHT INTO THURSDAY AFTERNOON AS
HIGH PRESSURE BRIEFLY BUILDS INTO THE REGION.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
NEXT WEATHER MAKER WILL BE LOW PRESSURE DEVELOPING ACROSS THE
PLAINS. WARM FRONT EXTENDING WELL ACROSS THE SOUTH WILL MOVE NORTH
FRIDAY INTO FRIDAY NIGHT. RIGHT NOW IT APPEARS THAT MANY LOCATIONS
COULD SEE A BRIEF 2-3 HOUR PERIOD OF FREEZING RAIN BEFORE WARMER AIR
MOVES IN AND CHANGES ALL PRECIPITATION TO RAIN. INCREASED POPS
SOMEWHAT...BUT RAGGED NATURE OF THE FRONT MAKES IT HARD TO PINPOINT
THE EXACT TIMING OF WHEN PRECIP COULD OCCUR. THERE SHOULD BE A BRIEF
LULL IN RAIN AFTER THE WARM FRONT MOVES THROUGH FRIDAY NIGHT AND THE
COLD FRONT COMES IN FOR SATURDAY. WITH WARM ADVECTION OUT OF THE
SOUTH...TEMPERATURES SHOULD EASILY CLIMB INTO THE 50S ON
SATURDAY...AND SOME LOCATIONS TO THE SOUTH COULD MAKE IT INTO THE
60S.

PASSAGE...BRINGING THE FRONT ACROSS EASTERN OHIO SUNDAY MORNING...AND
