LARGE SHIELD OF PRECIPITATION CONTINUES TO MOVE NEWD ACROSS THE OH
VALLEY. 1-2 IN/HR SNOWFALL RATES HAVE BEEN REPORTED...WITH HRLY
LIQUID EQUIVALENTS BETWEEN 0.05-0.15 INCHES. GIVEN DEEPENING OF
SURFACE LOW AS IT MOVES NEWD...AND CONTINUED STRONG MOISTURE
ADVECTION OFF THE SURFACE...EXPECT HEAVY SNOW RATES TO BE MAINTAINED
AS LARGE SCALE LIFT SHIFTS NEWD INTO WRN PA BY LATE EVENING. IT IS
QUITE APPARENT FROM RADAR TRENDS AND MULTIPLE MODELS THAT HEAVIEST
SNOW RATES WILL EXIST OVER SERN OH INTO SWRN PA.

FARTHER S INTO ERN WV...NWRN VA...AND WRN MD...A MIXTURE OF SLEET
AND SNOW IS EXPECTED DUE TO STRONG WARMING ALOFT. 00Z GSO SOUNDING
SHOWS WARMING TEMPERATURES NOW ABOVE FREEZING BETWEEN 750-800
MB...AND THIS WILL ADVECT NEWD INTO ERN WV AND WRN MD WHERE
PRECIPITATION SHOULD START OFF AS SNOW BUT WILL LIKELY CHANGE TO
SLEET BY 06Z.
