EVENT...AREA OF MODERATE TO HEAVY RAIN EXPANDING IN COVERAGE AND SPREADING
NORTHWARD ACROSS THE MIDDLE ATLANTIC REGION.
.
SATELLITE ANALYSIS AND TRENDS...SATELLITE IMAGERY SHOWS CLASSIC LARGE
COMMA SHAPED SYSTEM ACROSS EASTERN US. INITIAL SHOT OF WARM ADVECTION
RAIN SPREADING NORTHWARD FROM NC INTO VA/DC METRO AREA HAS INCREASED
IN COVERAGE AND INTENSITY (PER COMPOSITE RADAR LOOP) OVER THE PAST
COUPLE OF HOURS AS STRONG LOW LEVEL SOUTHERLY FLOW OVERRUNS WEST-EAST
ORIENTED WARM FRONT WHICH IS DEPICTED WELL IN LOW CLOUD PATTERN OFF THE NC
COAST. EARLIER MICROWAVE DATA AND MORE CURRENT GOES DERIVED PRECIPITABLE
WATER DATA SHOWED A PATCH OF 1.0-1.25" VALUES ACCOMPANYING THIS WARM
FRONT WHICH IS INDICATIVE OF UNSEASONABLY HIGH MOISTURE. IN ADDITION
TO THE ATLANTIC MOISTURE SOURCE, THE SYSTEM ALSO HAS A GULF OF MEXICO
MOISTURE CONNECTION WITH AT LEAST 1.5" PW VALUES FEEDING NORTHWARD INTO
THE SOUTHEAST AHEAD OF COLD FRONT. HAVE NOW NOTED SOME OBS OF HEAVY RAIN
(OVER .5"/HR TO NEAR 1.0"/HR) MOVING THROUGH THE RICHMOND/WAKEFIELD VA
AREA WHICH IS EMBEDDED IN THE AFORMENTIONED GROWING RAIN SHIELD THAT IS
ON TRACK TO SPREAD NORTH AND NORTHEASTWARD THROUGH THE WASHINGTON METRO
AREA AND EVENTUALLY CENT TO E PA/NJ/NY/NEW ENGLAND. FOLLOWING A BIT BEHIND
THAT SHOULD BE ANOTHER SLUG OF MODERATE TO HEAVY RAINFALL ASSOCIATED WITH
THE NEGATIVELY TILTED MID/UPPER LEVEL SYSTEM AND SFC COLD FRONT. GIVEN
THE WINTER SOIL CONDITIONS ESPECIALLY IN SPOTS FARTHER TO THE NORTH
(E PA TO SE NEW ENGLAND) CERTAINLY WILL HAVE TO MONITOR THE HEAVY RAIN
SITUATION FOR HYDRO ISSUES AS THE DAY PROGRESSES FOR AREAS EAST OF THE
SFC FREEZING LINE.
