SATELLITE ANALYSIS AND TRENDS...LATEST WV IMAGERY SHOWS SLOW MOVING
UPPER LOW S OF LONG ISLAND WITH DOWNSTREAM E ATLANTIC BLOCK SUGGESTING
SLOW MOVEMENT TO CONTINUE THROUGH THE NIGHT AND INTO TOMORROW.  A STRONG
SHORTWAVE TROF WAS ROTATING AROUND UPPER LOW AND APPEARED TO BE CROSSING
70W.  HAVE NOTED AN INCREASE IN CONVECTION BETWEEN DOWNSTREAM WCB AND
UPPER LOW AND THIS SUGGESTS THAT INSTANT OCCLUSION TYPE CYCLOGENESIS
SHOULD CONTINUE WITH ADDITIONAL PRESSURE FALLS LIKELY AS SECONDARY WCB
DEVELOPS AND ROTATES NW TOWARDS NEW ENGLAND.  SATELLITE INTERPRETATION
WOULD SUGGEST THAT LOW PRESSURE HAS LIKELY DEVELOPED IN A SYSTEM RELATIVE
SENSE TOWARDS TIP OF COMMA HEAD BUT IR IMAGERY WAS ALSO INDICATING A
NUMBER OF MESOLOWS EMBEDDED WITHIN THE LARGER SCALE CIRCULATION.  ONE SUCH
MESOLOW WAS LIFTING NW TOWARDS E TIP OF LONG ISLAND AND WAS AIDING
ENHANCED AREA OF CONVECTION BEGINNING TO AFFECT THIS AREA.  BLENDED PW
ANALYSIS WAS INDICATING DEEP STREAM OF TROPICAL MOISTURE GETTING PULLED
N OUT OF CARIBBEAN AHEAD OF SYSTEM AND INCREASINGLY ANOMALOUS E FLOW TO
THE NE OF SYSTEM WAS TRANSPORTING THIS MOISTURE BACK TOWARDS NEW ENGLAND.
.
SHORT TERM OUTLOOK VALID 0100-0700Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...AS LEAD SHORTWAVE TROF CONTINUES LIFTING NE
THROUGHOUT THE EVENING FLOW SHOULD CONTINUE BACKING OVER MOST OF E
PORTIONS OF NEW ENGLAND HELPING TO INCREASE DIFFLUENCE AND DEEP LAYER
LARGE SCALE FORCING.  THE LOW LEVEL RESPONSE SHOULD BE INCREASINGLY
ANOMALOUS EASTERLY FLOW AND MOISTURE TRANSPORT INTO NEW ENGLAND.  THERE
WERE SOME INDICATIONS ON THE LATEST SURFACE ANALYSIS OF VEERING WINDS
E OF A HYA TO MVY AXIS WHICH COULD INDICATE DEVELOPING COASTAL FRONT.
0Z SOUNDING WAS INDICATING SOME WEAK INSTABILITY ALONG THIS AXIS WITH
STRONGLY VEERED PROFILES IMPLYING STRONG WAA.  THIS WOULD ALL SUGGEST
THAT HEAVY RAINFALL SHOULD CONTINUE TO DEVELOP WITHIN INCREASING E FLOW
AS LOW CONTINUES TO DEVELOP OVERNIGHT.  LARGE SCALE FORCING AND THERMAL
RIDGE AXIS WOULD TEND TO SUGGEST INCREASING RAINFALL OVER PORTIONS OF
MA/CT/RI/LI DURING THE EARLY PART OF THE NIGHT AND SHIFTING NE TOWARDS
SE NH/COASTAL ME TOWARDS THE END OF THIS TIME PERIOD AND BEYOND.
