.
SATELLITE ANALYSIS AND TRENDS...WV LOOP SHOWS DUMBBELL VORT SHAPE WITH
UPPER LOW OVER C NC.  THE EASTERN LOBE HAS BEEN SWINGING NORTHWARD WITH
GOOD VORT ADVECTION WITH GOOD BROAD SCALE ASCENT.  AT THE SFC SIGNIFICANT
MST CONVERGENCE ALONG THE BAND HAS LEAD TO SIGNIFICANT DEEPENING WITH
COOLING IR TOPS TAKING ON A WEAK WEDGE APPEARANCE ACROSS SE VA (SUFFOLK
CITY) TO PASQUOTANK COUNTY ACROSS ALBEMARLE SOUND INTO THE ALLIGATOR
RIVER/W DARE COUNTY.  THESE CELLS HAVE TOPS TO -45C WHICH IS QUITE
IMPRESSIVE WITH THE LOW EL DUE TO UPPER LOW...A SPINE OF OVERSHOOTING TOPS
ALONG THIS LINE SHOWS THE VIGOR.  WITH PWS OF 1.0-1.2" BEING ESTIMATED
BY MICROWAVE PW ANALYSIS FIELDS...AND VERY HIGH FLUX DUE TO THE STRONG
COVERGENCE...WOULD EXPECT RATES WELL OVER 1.5"/HR ALONG THIS LINE WITH
ISOLATED 2-2.5" RATES WITH MERGERS AS THE LINE CONTINUES TO EXPAND.
THIS LINE HAS REMAINED STATIONARY FOR WELL OVER THE HOUR OVER PASQUOTANK
COUNTY AND WITH PRIOR STORMS DEVELOPING (SEE 1045Z AND 1145Z IMAGES)
OVER THE AREA AND SHIFTING NW INTO VA GATES COUNTY...TOTALS OVER 3" ARE
VERY LIKELY WITH ISOLATED 4" TOTALS WITHIN THE LAST 3 HOURS.  THIS LINE
IS NOT GOING TO MOVE VERY MUCH OVER THE NEXT HOUR OR SO AS THE WESTERN
LOBE OF VORTICITY APPEARS TO BE LEADING THE OVERALL UPPER LOW CIRCULATION
TOWARD THE WEST...LEAVING THE DISCUSSED AREA WITHIN PROLONGED STRONG
SFC MOISTURE CONVERGENCE ALONG THE BAND AND SOUTHWARD TO THE PAMILICO
SOUND AND OCRACOKE ISLAND.
