930 AM UPDATE...
ONLY A FEW COSMETIC CHANGES TO HOURLY GRIDS...FORECAST IS STILL ON
TRACK. STILL EXPECT AT LEAST PARTLY CLOUDY SKIES FOR ALL LOWLANDS
BY EARLY AFTERNOON..WITH CLOUDS DISPERSING OVER THE MOUNTAINS BY
MID/LATE AFTERNOON.

UPDATE...
NO CHANGES TO THE FORECAST THIS MORNING.

PREVIOUS DISCUSSION...
STRONG LOW PRESSURE TRACKS UP THE EAST COAST PROVIDING A STRONG LATE
WINTER STORM OVER THE CAROLINAS AND VIRGINIA. MUCH OF THAT
PRECIPITATION IS RAIN...BUT WINTRY CONDITIONS DO LIE ON THE WESTERN
AND NORTHWESTERN EDGE OF THE SYSTEM...APPROACHING THE SOUTHERN
MOUNTAINS OF WEST VIRGINIA. PRECIPITATION/SNOW IS NOT MAKING IT INTO
BLF AT THIS TIME...WITH RADAR IMAGERY INCONCLUSIVE IN THE RNK
PORTION OF WEST VIRGINIA. WAS FORCED TO KEEP THE SLIGHT CHANCES OF
PRECIPITATION GOING ALONG THE EASTERN FRINGE OF THE CWA...BUT
CONFIDENCE IS LOW FOR PRECIPITATION THERE...LET ALONE MEASURABLE.

IN THE MEANTIME...JUST DEALING WITH THE HIGH LEVEL MOISTURE OF THIS
SYSTEM. OHIO RIVER COUNTIES SHOULD BE MAINLY CLEAR JUST AFTER
DAWN...WITH THE WEST VIRGINIA LOWLANDS TO FOLLOW IN THE EARLY
AFTERNOON. BY SUNSET...THE SKY WILL BE MOSTLY CLEAR...WITH CIRRUS
INFILTRATING ONCE AGAIN BY DAWN WITH A VERY WEAK TROUGH AXIS ALOFT
APPROACHING.

MILD CONDITIONS CONTINUE WITH LOWLANDS IN THE MID 50S TODAY...AND
MOUNTAINS IN THE LOW TO UPPER 40S.

.SHORT TERM /SATURDAY THROUGH MONDAY/...
WEST TO NORTHWEST FLOW ALOFT THIS WEEKEND INTO EARLY NEXT WEEK HAS
THE NORTHERN STREAM BEING DOMINANT. A WEAK NORTHERN STREAM SHORT
WAVE AND ASSOCIATED WEAK COOL FRONT DROPS ACROSS THE AREA SATURDAY
NIGHT. THE NAM IS AN OUTLIER IN AMPLIFYING THIS FEATURE AND SLOWING
IT SOMEWHAT...SO THE FASTER AND FLATTER GFS WAS USED FOR DETAILS.
WITH MILD TEMPERATURES AHEAD OF THE FRONT ON SOUTHERLY FLOW...SOME
LIGHT RAIN WILL ENTER SOUTHEAST OHIO AND NORTHWEST WEST VIRGINIA
LATER SATURDAY AFTERNOON...THEN SHIFT SOUTHEAST WITH THE FRONT
SATURDAY NIGHT. THE FRONT WILL BE EAST OF THE MOUNTAINS BY SUNDAY
MORNING...WITH ANY LINGERING RAIN OR HIGH ELEVATION MOUNTAIN SNOW
ENDING QUICKLY EARLY SUNDAY. ONLY A BRIEF AND MINOR COOL DOWN IS
EXPECTED SUNDAY UNDER DRY HIGH PRESSURE. THE HIGH SHIFTS EAST BY
MONDAY WITH SOUTHERLY FLOW RETURNING...WITH DRY WEATHER BUT A
WARMING TREND TO SLIGHTLY ABOVE NORMAL TEMPERATURES THROUGH TUESDAY.

&&

.LONG TERM /MONDAY NIGHT THROUGH THURSDAY/...
THE MIDDLE OF NEXT WEEK SHOWS A CONTINUED DIFFERENCE BETWEEN THE
EURO AND NOAM MODELS. EACH IS CONSISTENT WITH THEMSELVES IN THE THE
EURO SHOWS A MAJOR STORM DUE TO PHASING OF THE NORTHERN AND SOUTHERN
STREAM...WHILE THE NOAM MODELS SHOW LITTLE PHASING WITH A WEAKER AND
FASTER NORTHERN STREAM SYSTEM MOVING THROUGH. WILL TEND TO LEAN WITH
WPC AND THE EURO CAMP...BUT PRECIP WILL BE MAINLY RAIN WITH THIS
SYSTEM TIL MAYBE THE END WEDNESDAY NIGHT.
