SCTD TSTMS DVLPG ALONG THE COLD FRONT IN PA. NOT SURE IF THEY WILL HOLD
TOGETHER AS THEY HEAD E DUE TO THE CLOUDS AND OCEAN FLOW HELPING KEEP
THE BLYR STABLE. HOWEVER...IF THE CLOUDS AND BREAK FOR AN HOUR OR TWO
ALLOWING SUNSHINE...THEN THE TSTMS WOULD CONT TO DVLP AND PSBLY INCR IN
INTENSITY TOO. CURRENTLY, I THINK ACTIVITY SHOULD REMAIN SCTD. ALSO,
THE ONLY TSTMS THAT WOULD HAVE STRONG WINDS IN THE FCST AREA WILL
PROBABLY DVLP UPSTREAM.

BY MIDNIGHT...ALL PCPN SHOULD BE GONE, WITH CLEARING BY MRNG. SOME
CU/STRATOCU DVLPS FROM HEATING SUN...OTHERWISE MOSTLY CLEAR SKIES
THROUGH SUN NIGHT. MON...ALL MODELS INDICATE THE JET STREAM LIFTING N
AND THE FCST AREA UNDER THE INFLUENCE OF A CLOSED UPPER LOW TO THE W.
THIS SHOULD ALLOW MOISTURE AND THEREBY CLOUDS TO INCREASE DURING
MONDAY...ESPECIALLY SOUTH. FOR NOW...I WILL GO FOR INCR CLDS S BUT KEEP
MOSTLY SUNNY NORTH.

TEMPS...MET GUIDANCE GENLY LOOKS GOOD.

SOME PATCHY FOG COULD DVLP TNGT SINCE IT RAINED TODAY AND WITH THE
CLEARING SKIES TEMPS SHOULD DROP TO THE DEWPTS. HOWEVER...WITH THE CAA,
THERE MAY BE ENOUGH LINGERING GRADIENT TO PREVENT ITS FORMATION, SO I
WILL LEAVE IT OUT FOR NOW.

.PHI...
DE...NONE.
MD...NONE.
NJ...NONE.
PA...NONE.
MARINE...NONE.
