SATELLITE ANALYSIS AND TRENDS...05Z SFC ANALYSIS INDICATES SFC LOW
PRESSURE OVER NRN NJ LIFTING NEWD ALONG THE NEW ENGLAND COASTLINE. NRN
PART OF THE SYSTEM HAS BECOME SLIGHTLY NEGATIVELY TILTED DUE TO THE PUSH
OF A CLOSED UPPER LOW AND A 100KT STLT DERIVED JET STREAK EWD ACROSS THE
OH VLY/MID-ATLANTIC REGION..PUSHING THE CENTRAL PORTION OF THE MOISTURE
AXIS QUICKLY OFF THE ATLANTIC SEABOARD. MOST RECENT MICROWAVE DATA SHOWED
A POOL OF RICH MOISTURE OFF THE COAST OF MD/DE/NJ AS OF 0202Z WHICH
HAS MOVED NEWD TWDS COASTAL NEW ENGLAND. PW VALUES WITHIN THIS POOL OF
MOISTURE WERE BETWEEN 1.5-1.9" DOWN TO THE VA/NC BORDER WHERE A SMALL
BREAK IN THE RICHEST MOISTURE MOISTURE OCCURRED..BEFORE CONTINUING FROM
OFF THE CENTRAL NC COAST SWWD. AREAL AVG MICROWAVE RAINRATES AT THAT
TIME WERE 0.1-0.2"/HR WITH A PIXEL OR TWO OF 0.25"/HR BUT CONSIDERING
THE AMOUNT OF CLOUD TOP COOLING THAT HAS OCCURRED SINCE 02Z..EXPECT THAT
RAINFALL RATES HAVE ALSO INCREASED STEADILY AS WELL. AUTOMATED STLT
ESTIMATES INDICATE MAX RAINFALL RATES OF 0.5-0.6"/HR IN THE STRONGER
CELLS MOVING NWD TWDS/ACROSS RI/ERN MA/ERN NH/WRN ME. CLOUDS TOPS S OF
RI/ERN MA HAVE COOLED TO TEMPS OF -55 TO -58C AND ARE WITHIN THE LLJ
AXIS WHICH LOCAL VWP'S INDICATE IS AT 40-50KTS FROM THE SSW. SHOULD BE
A SLIGHT ROTATION OF LLJ OVER THE NEXT 3-4 HRS TO BECOME SRLY/SSERLY
AS SOME ADDTL NEGATIVE TILTING SHOULD TAKE PLACE ALLOWING FOR FOCUS OF
HEAVIEST RAIN TO REMAIN ACROSS ERN MA/ERN NH/SW ME/AND PERHAPS EVEN RI.
