...WINTRY WEATHER MIX POSSIBLE FOR MID WEEK...

THE COMBINATION OF A COLD ARCTIC AIR MASS WITH LOW PRESSURE MOVING 
ALONG A FRONTAL BOUNDARY WILL BRING THE CHANCE OF A WINTRY WEATHER 
MIX FOR MID WEEK TO PARTS OF THE AREA.  AN EAST/WEST STATIONARY 
FRONT WILL BECOME ESTABLISHED ACROSS THE MID ATLANTIC REGION BY 
TUESDAY...PROBABLY A LITTLE SOUTH OF THE MASON-DIXON LINE. THEN A 
RE-ENFORCEMENT OF COLD ARCTIC AIR IS FORECAST TO PUSH IN FROM THE 
NORTH ON WEDNESDAY.  MEANWHILE...A LOW PRESSURE WAVE DEVELOPING 
ALONG THE FRONT OVER THE OHIO VALLEY WILL SPREAD PRECIPITATION 
EASTWARD INTO THE MID ATLANTIC AREA ON TUESDAY NIGHT AND WEDNESDAY.

THE RESULT OF ALL THIS WILL LIKELY BE A WINTRY MIX OF PRECIPITATION 
OVER PARTS OF EASTERN PENNSYLVANIA AND NORTHERN/CENTRAL NEW JERSEY. 
RAIN ON TUESDAY NIGHT MAY CHANGE OVER TO FREEZING RAIN WEDNESDAY 
MORNING AND THEN TO SLEET OR SNOW WEDNESDAY AFTERNOON AND NIGHT. 
PRECIPITATION COULD CHANGE BACK TO RAIN ON THURSDAY AS THE COLD AIR 
RETREATS NORTH. THE TIMING OF THESE CHANGEOVERS IS UNCERTAIN FOR 
NOW. AREAS NORTH AND WEST OF THE CITY OF PHILADELPHIA ARE MOST 
LIKELY TO SEE SOME KIND OF FREEZING OR FROZEN PRECIPITATION.

STAY TUNED TO NOAA WEATHER RADIO, OR YOUR LOCAL MEDIA OUTLET FOR
FURTHER UPDATES.
