SATELLITE ANALYSIS AND TRENDS...WV LOOP SHOWS SHORTWAVE DROPPING OUT OF
THE GREAT LAKES REGION LAST NIGHT TOWARD THE MID ATLANTIC WHERE A SSW TO
NNE CONFLUENCE ZONE WITH EMBEDDED SHORTWAVES DOMINATED THE FLOW...SLOWING
THE SHORTWAVE... WHICH IN TURN AMPLIFIED IT.  THUNDERSTORMS HAVE DEVELOPED
ALONG IT AND TAKEN A CURLED APPEARANCE TO THE LINE TO MIMIC THE UPPER
LEVEL VORT...WITH A TURNING OF THE SOUTHERN PORTION OF THE LINE ACROSS S
NJ/DE/E MD WHERE THE LINE CONTINUES TO DEVELOP UPSTREAM WITH THE ENHANCED
WESTERLY FLOW ALOFT.  CURRENTLY...THUNDERSTORMS ALONG THE LINE CONTINUE
TO DEVELOP/INTENSIFY AS THE ONSHORE SEA BREEZES ARE ENHANCING LOW LEVEL
CONVERGENCE AND INCRAESED MOISTURE FLUX TO THE STORMS.  IR SHOWS A LARGE
AREA OF -50 TO -60C TOPS MELDING INTO A LARGER COMPLEX INDICATING MERGERS
WITHIN THE LINE. PWS OF 1.9 TO 2.0" HAVE BEEN MEASURED BY GPS NETWORK
AND EARLY MORNING RAOBS...SO BASED ON ALL THIS INFO...RATES IN EXCESS
OF 2.0"/HR ARE ESTIMATED ALONG THE LINE...BUT HIGHER AMOUNTS THAT WILL
ADD .5" TO THE TOTAL WHERE MERGERS HAVE OCCURRED SUCH AS SE BURLINGTON
COUNTY NJ AND SUSSEX COUNTY DE BECOME AREAS OF MOST CONCERN. THE SOUTHERN
PORTION OF THE LINE HAS ADDITIONAL ISSUES ACROSS S DE WHERE CONTINUED
REDEVELOPMENT OF THE LINE TOWARD THE WEST COULD LEAD TO SOME TRAINING
AS CELL MOTION IS PARALLEL AND VERY SLOW.
