.SYNOPSIS...
THE DEEP UPPER TROUGH OVER THE EASTERN CONTINENT WILL LIFT INTO
CANADA...BUT THE FLOW WILL REMAIN NORTHWESTERLY. WEAK SURFACE HIGH
PRESSURE WILL VISIT FOR WEDNESDAY...BUT FAST FLOW WILL BRING A
LOW PRESSURE SYSTEM AND RAIN SHOWERS THROUGH THE OHIO VALLEY AND
INTO THE AREA FOR THURSDAY. MORE WAVES OF LOW PRESSURE WILL PASS
JUST TO THE SOUTH OF THE STATE INTO THE WEEKEND. COLD CANADIAN AIR
WILL DROP DOWN OVER THE EASTERN CONUS FOR EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
BROKEN CLOUDS OVER THE NORTHERN TWO-THIRDS OF THE AREA WILL HOLD A
FEW SNOW SHOWERS IN THE NORTHERN TIER. ANY RETURNS ON RADAR TO THE
SE OF THE ALLEGHENY MTS MOST LIKELY NOT REACHING THE GROUND DUE TO
DRY SFC DEWPOINTS. CIGS ARE 5KFT OR HIGHER. CAN SEE SOME VIRGA OUT
THE WINDOW...AND FURTHER/BETTER DOWNSLOPING TO THE SE WILL KEEP
MOST OF THE MOISTURE/DROPS/FLAKES FROM REACHING THE GROUND.
STABILIZATION THIS EVENING WILL DECREASE THE WINDS BUT WILL
PROBABLY NOT CAUSE THEM TO GO ENTIRELY CALM - EXCEPT PERHAPS IN
THE SHELTERED VALLEYS IN THE SRN PART OF THE AREA. THE HILL TOPS
SHOULD REMAIN IN THE MID 30S. AREAS WHICH DO GET INTO THE L-M30S
LATE TONIGHT IN THE S WILL PROBABLY SEE SOME PATCHY FROST IN THE
COLD LOCATIONS LIKE KTHV...BUT A WIDESPREAD FROST IS NOT EXPECTED
AT THIS TIME. WILL THEREFORE JUST MENTION PATCHY FROST FOR NOW IN
THE S.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/...
HIGH PRESSURE FLOATS IN AFTER A COOL START ON WED. CLOUDS IN THE
NE EARLY WILL LIFT OUT AND LEAVE MOSTLY SUNNY SKIES. WARM
ADVECTION BRINGS 8H TEMPS TO 0C NE AND +4C SW BY SUNSET. THIS AND
GOOD MIXING IN ALMOST FULL SUN WILL BRING MAXES BACK CLOSER TO BUT
STILL 5-10F BELOW NORMALS WITH 60S IN THE SE AND U40S TO LOWER 50S
OVER THE SNOW-COVERED GROUND.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
NEXT STORM SYSTEM APPROACHES WED NIGHT WITH SFC LOW AHEAD OF UPPER
LOW MOVING THROUGH NW FLOW. CENTER OF SFC LOW SLIDES JUST SOUTH OF
PA...BUT SE/E FLOW DEVELOPS AHEAD OF IT BRINGING IN COOLER MARINE
AIR WHICH WILL INCREASE OVERRUNNING SURFACE. RAIN APPEARS LIKELY
THURSDAY ACROSS MAINLY THE SOUTHERN HALF OF CWA...WITH SCT
SHOWERS FURTHER NORTH IN DRIER AIR. TEMPS THU SHOULD APPROACH
NORMAL...BUT THICKENING CLOUDS AND INCREASED SE FLOW MAY RESULT IN
BELOW NORMAL HIGHS.

HIGH PRESSURE RIDGES NOSES IN FROM THE NW ON FRI BRINGING SLIGHTLY
BELOW NORMAL TEMPERATURES...BUT FRONTAL BOUNDARY STALLS E-W OVER
THE MID ATLANTIC STATES...PREPARING TO SLIDE BACK NORTHWARD THIS
WEEKEND. MODELS IN BETTER AGREEMENT TODAY THAN PREV RUNS...THOUGH
TIMING DIFFERENCES REMAIN BETWEEN ECMWF/GFS. ANOTHER SFC WAVE
RIPPLES ALONG THE FRONT FROM THE SOUTHERN PLAINS ON SAT...WHICH
WILL AGAIN FOCUS RAIN MAINLY ON SOUTHERN HALF OF CWA SAT INTO SUN.

BY MONDAY...FRONT CLEARS TO THE EAST AS SPRAWLING HIGH PRESSURE
AREA MOVES IN. DRY WEATHER WILL BE IN STORE MON-WED. MONDAY WILL
BE COOLER...WITH WARMING TEMPS TUE AND WED DURING THE DAY. NIGHTS
WILL BE NOTICABLY CHILLY WITH READINGS IN THE 20S LIKELY IN THE
NORTHERN AND PORTIONS OF CENTRAL MTNS.

&&

.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
CYCLONIC FLOW WILL KEEP LOTS OF LOW CLOUDS OVER THE NRN TERMINALS
INTO THE NIGHT. AFTER SUNSET...SOME OF THE CLOUDS ON THE SOUTHERN
FRINGE WILL DISSIPATE...BUT MUCH OF THIS SHIELD WILL REMAIN...AND
SLOWLY ERODE FROM SW TO NE. MVFR CIGS/VSBYS NEAR BFD WILL CONTINUE
AND COULD EXTEND INTO KIPT THIS EVENING. THE HEIGHTS START TO
RISE ALOFT AND COLD AIR GOES WITH IT IN THE EARLY MORNING. WILL
CLEAR THE SKIES AT THE SRN LOCATIONS IN THE LATE NIGHT OR
CERTAINLY SHORTLY AFTER SUNRISE.

A TIGHT PRES GRADIENT ON THE WEST SIDE OF THE LOW WILL PRODUCE
GUSTY NW WINDS INTO EVENING. WINDS WILL BECOME LESS GUSTY BUT
PROBABLY STAY AT LEAST 4-5KTS THROUGH THE NIGHT. HIGH CLOUDS
ADVANCE IN FROM THE WEST FOR WED EVENING AND RAIN MOVES IN FROM
THE W/SW LATER WED NIGHT. LOWERED CIGS AND VSBYS LIKELY WED NIGHT
AND THURS IN RAIN.
