EVENT...UPDATE TO SPENES MESSAGE SENT THIS MORNING FOR HEAVY RAIN THREAT
CENTERED AROUND NW SC.
.
SHORT TERM OUTLOOK VALID 2030-0300Z...MEDIUM TO HIGH CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...THE PRIMARY FEATURES OF INTEREST FOR THE
EVENING AND OVERNIGHT HOURS INCLUDE A LOW LEVEL BOUNDARY DRAPED FROM
W CENT NC(JUST E OF CHARLOTTE) TO NE GA (E OF ATHENS) AND EMBEDDED
IMPULSES IN THE BACKING MID/UPPER LEVEL FLOW PER WATER VAPOR ANIMATION.
EARLIER IMPULSE/UPPER LEVEL SPEED MAX MOVING ACROSS THE S AND CENT
APPALACHIANS HELPED PROVIDE LIFT OVER THIS LOWER LEVEL BOUNDARY AND
INTO THE TERRAIN OF NW SC FOR ROUND OF LOCALLY VERY HEAVY RAINFALL THIS
MORNING WHICH HAS FINALLY DIMINISHED WITH DISTURBANCE NOW PASSING OVER
THE MID-ATLANTIC REGION. HOWEVER, INCREASINGLY MOIST CONVERGENT LOW LEVEL
INFLOW CONTINUES OFF OF THE ATLANTIC PER ANALYSIS AND ALSO DEPICTED IN
VISIBLE ANIMATION SHOWING CONVERGING CU BANDS OFFSHORE. DAYTIME HEATING
AND POCKETS OF GREATER INSTABILITY/CAPE HAS RESULTED IN SCATTERED
CONVECTIVE DEVELOPMENT OVER PORTIONS OF E GA AND CENT-SE SC WITH MOST
CELL MOTIONS GENERALLY TO THE N. WATCHING UPSTREAM DISTURBANCE MOVING FROM
MS INTO AL WHICH WILL LIKELY CONTINUE TO AID IN NEW CELL DEVELOPMENT AND
ISENTROPIC LIFT PRIMARILY ACROSS CENT TO NW SC/W CENT TO W NC DURING THE
EVENING/OVERNIGHT HOURS AS UPPER LEVEL FLOW CONTINUES TO BACK PER WATER
VAPOR ANIMATION. DEFINITELY VERY CONCERNED WITH THIS EVOLVING HEAVY RAIN
SITUATION OVERNIGHT WITH SE 850MB INFLOW OFF OF THE ATLANTIC ALREADY
TAPPING INTO PREEXISTING BAROCLINIC ZONE OFFSHORE. PRECIPITABLE WATER
VALUES ARE STEADILY INCREASING ACROSS THE REGION CENTERED OVER SC WITH
RECENT BLENDED TPW PRODUCT SHOWING AROUND 1.8" PRESENT. ADDITIONALLY,
HAVE SEEN RECENT RAP AND HRRR FORECASTS WHICH CONTINUE TO POINT TOWARD THE
CENT/W PORTIONS OF SC/NC AS THE FOCAL POINT FOR THE BETTER LIFT. FORECAST
FREEZING LEVELS WELL ABOVE 12,000FT SHOULD PROVIDE FOR A COMBINATION
OF STRATIFORM MODERATE/HEAVY AND EMBEDDED SHALLOW VERY EFFICIENT WARMER
RAIN PROCESSES IN THIS REGION...SEE GRAPHIC APPENDED TO TEXT PRODUCT ON
THE INTERNET OUTLINING THREAT AREA IN APPROX 10 MINUTES.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
