.
SATELLITE ANALYSIS AND TRENDS...STLT IMAGERY ANIMATION HAS SHOWN  A
FEW   SIGNIFICANT TRENDS IN THE 2-3 HRS. FIRST..SUBSYNOTPIC SCALE WAVE/
BAROCLINIC LEAF HAS BEEN RAPIDLY EVOLVING AS IT MOVES ACRS THE AREA FM ERN
NY AND MUCH OF NEW ENGLAND. COVERAGE HAS BEEN EXPANDING AND CLOUD TOPS
HAVE BEEN COOLING OVER E NY/MA/VT/NH. THIS AREA LIES WELL E OF SFC COLD
FRONT..N OF WARM FRONT OVER SRN NEW ENGLAND..PER SFC DATA/ANALYSIS. AT THE
SAME TIME..SMALL BUT INCR SW-NE BAND OF CNVTN EXTENDING FM CENTRAL/NRN
NJ TO SE NY IS MOVG EWD. WITH WV IMAGERY ANIMATION SHOWING SOME BACKING
OF FLOW OUT AHEAD OF SHARPENING AND EWD MOVG GREAT LAKES/OH VALLEY
SHORT WAVE..WOULD EXPECT THIS LINE OF TSTMS TO MOVE NEWD TWD SRN NEW
ENGLAND. FURTHER STRENGTHENING IS LIKLEY..AS OBJECTIVE ANALYSIS SHOWS
SFC CONVERGENCE BULLESYE CENTERED OVER CT/RI  WITH GENERAL AREA OF SFC
CONVERGENCE ENCOMPASSING THE AREA FM S VT/NH/ME THRU LI/NE NJ.
.
ALTHOUGH MOVEMENT OF SYSTEMS MENTIONED ABOVE WILL PRECLUDE PROLONGED
HEAVY RAINFALL INTENSITIES..HVY DOWNBURSTS OF 0.5-1" IN LESS THAN AN HR
IS LIKELY. PW'S ARE ARE AOA 2" INVOF SRN NEW ENGLAND/LI/SE NY..WHICH WILL
CONTRIBUTE TO HVY RAIN RATES.  WHILE PROGRESSIVE MOVEMENT OVER NYC/LI WILL
HOLD DOWN RAINFALL TOTALS..SITUATION WILL BE SOMEWHAT DIFFERENT FURTHER
N...WHERE A COUPLE OF ROUNDS OF HVY PRECIP WILL BE CHANNELED..AFFECTING
CT/RI/MA/SE NH/S MA. DO NOT SEE HVY TOTALS TO BE WIDESRPEAD..BUT BASED
ON STLT TRENDS CAN SEE POSSIBILITY OF PARTS OF MA/CT/RI RECEIVING AN
ADDITIONAL 1-2".
