ZONE SUGGESTIONS...
DROP WATCHES IN ALL BUT THE MID AND UPPER SUSQUEHANNA AND
NORTHERN MOUNTAINS.  SPECIFIC FLOOD WARNINGS FOR STREAMS WILL
CONTINUE IN AREAS WHERE RUNOFF TO LARGER STREAMS CONTINUES.

MODELS AGREE PRETTY WELL ON THE POSITION OF THE LOW OVER
SOUTHEAST PA AND KEEP MOST OF THE HEAVIER PRECIP CONFINED TO THE
NORTHEAST SECTION OF THE STATE.  88D HAS BEEN TRACKING THE PRECIP
NORTHWEST ACROSS THE AREA...AND MOST OF THE PRECIPITATION IS OVER
ACROSS THE LOWER SUSQUEHANNA AND AREAS OF SOUTH CENTRAL PA.
SATELLITE ALSO SHOWS DRYING IN THE MID AND HIGH LEVELS ACROSS
SOUTH CENTRAL PA WITH THE MULTI-LAYERED CLOUDS WRAPPED AROUND THE
TOP OF THE UPPER LOW FROM ERI SOUTHEAST TO ABE.  MODELS ALSO
CONCUR THAT UPPER CUT OFF LOW IS NOT GOING ANYWHERE FAST BUT WILL
GRADUALLY MOVE NORTHEAST OVER 48 HOURS. COORDINATED WITH PIT AND
PHL BY PHONE AND EXCEPT FOR SOME LAST MINUTE CHANGES CONSENSUS IS
TO KEEP THE WATCHES UP ACROSS UPPER SUSQUEHANNA AND PARTS OF
MIDDLE SUSQUEHANNA AND NORTHERN MOUNTAINS.

CONCURRED WITH PIT THAT GIVEN THE HISTORY...MOS TEMPS ARE TOO
WARM OVERNIGHT  AND SNOW SHOULD CONTINUE TO MIX WITH RAIN
ESPECIALLY ACROSS HIGHER ELEVATIONS.
