.SYNOPSIS...
PRECIPITATION SHOULD COME TO AN END THIS EVENING...ALTHOUGH THERE
WILL BE A BRIEF PERIOD OF GUSTY WINDS AS A COLD FRONT COMES THROUGH.
EXPECT CALM WEATHER FOR CHRISTMAS DAY BEFORE RAIN MOVES BACK IN FOR
FRIDAY AND SATURDAY.

&&

.NEAR TERM /THROUGH THURSDAY/...
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

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.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
ECMWF/GFS HAVE COME INTO BETTER AGREEMENT WITH THE COLD FRONTAL
PASSAGE...BRINGING THE FRONT ACROSS EASTERN OHIO SUNDAY MORNING...AND
ACROSS WESTERN PA SUNDAY AFTN. HAVE RAISED POPS TO LIKELY WITH THE
FRONTAL PASSAGE. PRECIP WILL DIMINISH SUNDAY NIGHT IN THE WAKE OF
THE FRONT...WITH DRY AND SEASONABLE CONDITIONS FOR EARLY NEXT WEEK.

CHANCE OF MAINLY SNOW SHOWERS.

&&

.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
NUMEROUS/WIDESPREAD SHOWERS ARE CROSSING THE REGION THIS
AFTN AS A COLD FRONT APPROACHES. THE FRONT WILL CROSS EASTERN
OHIO IN THE NEXT FEW HRS...AND CROSS WESTERN PA THIS EVENING.

CONDITIONS IMPROVING TO LOW END VFR TONIGHT. SOUTHERLY WINDS ARE
BEGINNING TO INCREASE AHEAD OF THE FRONT. WITH THIS INCREASE IN
SURFACE WINDS...LOW LEVEL WIND SHEAR THREAT WILL DIMINISH. WINDS

ALONG/BEHIND THE FRONT INCREASING TO 20-25KT WITH GUSTS TO 30-35KT.
WINDS WILL DIMINISH OVERNIGHT/EARLY CHRISTMAS MORNING. HIGH PRESSURE
