.
SATELLITE ANALYSIS AND TRENDS...NORTHEASTERN PORTIONS OF NEW ENGLAND WHICH
INCLUDE NH AND ME ARE SHOWN TO BE LOCATED IN A REGION OF BEST UPPER LVL
DIVERGENCE AS A RESULT OF LEFT-EXIT REGION AND RIGHT-ENTRANCE REGION JET
DYNAMICS AIDING IN THE ENHANCEMENT OF UVVS FROM TWO 300MB JET STREAKS.
STLT WINDS INDICATE A JET STREAK ORIENTED SW-NE POSITIONED S OF LONG
ISLAND WITH THE SECOND JET STREAK NNW OF ME/NH ORIENTED SSE-NNW.
MID-LVL TROUGH AXIS THIS MORNING IS NEGATIVELY TILTED SE-NW ACROSS
WEST VIRGINIA THRU PA/OH PER WV ANALYSIS.  LLVL FACTORS ARE ALSO IN
LINE THIS MORNING FOR CONTINUED MOD/HVY RAINS TO CONTINUE ACROSS THE
NORTHEAST TODAY.  LLVL WINDS HAVE REMAINED OUT OF THE SSE SINCE 02Z
ACCORDING TO PROFILER DATA SUGGESTING CONTINUED MOISTURE TRANSPORT INTO
THE NORTHEAST TODAY WITH TPW STILL ABOVE 200 PERCENT OF NORMAL.

IR IMAGERY HAS A DISTINCT BACK EDGE OF COLDER-TOP CLOUD JUST MOVING NE
OUT OF NH AND INTO ME AT 1215Z..POTENTIALLY SUGGESTING THAT THE HVY RAINS
WILL BEGIN TO SUBSIDE..HOWEVER FIRST FEW VIS IMAGES OF THE DAY PAINT A
SLIGHTLY DIFFERENT STORY. VIS IMAGERY REVEALS THAT ADDITIONAL MOD/HVY
RAIN IS FOUND ASSOCIATED WITH WARM-TOPPED CLOUDS..WITH SOME   CLOUD TOP
COOLING SEEN IN LAST FEW IMAGES IN IR..ARE EXPECTED TO ROTATE AND BECOME
MORE SE-NW ORIENTED THROUGHOUT THE DAY IN RESPONSE TO THE MID-LVL TROUGH
BEING NEGATIVELY TILTED..HELPING TO PROLONG THE EVENT.  THE COMBINATION
OF RELATIVELY HIGH MOISTURE STILL EXPECTED TO BE DRAWN IN AT LLVLS FROM
THE S..ENHANCED UVVS FROM THE MID-LVL TROUGH TO THE WEST AND MOD/STRONG
UPPER LVL DIVERGENCE SHOULD KEEP THE RAIN AROUND FOR NH AND ME INTO THE
LATE AFTERNOON.  PORTIONS OF NE ME SHOULD EXPECTED TO HOLD ONTO THE RAIN
A BIT LONGER..LINGERING INTO EARLY EVENING.

CURRENT THINKING IS MOST OF ME AND EXTREME E NH SHOULD RECEIVE AROUND
0.25" WITH POSSIBLE HIGHER AMOUNTS OF 0.50-1.0" CENTERED OVER CENTRAL
AND SOUTH-CENTRAL ME OVER THE NEXT 6-HRS.  THE 1.0" SWATH IS DUE TO THE
FACT THAT THE HVY RAINS FROM THE COLD CLOUD-TOP SHIELD WILL REMAIN OVER
CENTRAL AND E ME THIS MORNING AND THEN THIS AFTERNOON RAIN FROM THE
WARM-TOP CLOUDS WILL ROTATE THROUGH.
