SATELLITE ANALYSIS AND TRENDS...MICROWAVE ANALYSIS THIS MORNING
SHOWED CHARACTERISTIC FRONTAL SIGNATURE/BOUNDARY IN 89/85GHZ CHANNEL
IMAGERY THAT HAS DROPPED SOUTH PAST 24HRS ALONG THE SE COAST TO CURRENT
POSITION CENTERED OVER FAR NE FLORIDA.  HIGH PW MOISTURE OF NEAR 2.0
INCHES HAS POOLED ALONG THE BOUNDARY CLOSE TO THE COAST.  EARLIER AMSU
MICROWAVE RAIN RATES JUST BEFORE 12Z SHOWED A MAX RAIN RATE OF OVER 1.2
INCHES PER HR JUST OFF THE COAST...WHILE SSMI 1251Z PASS HAD SIMILAR
RATES CLOSE TO THE COAST.  NESDIS GOES HYDROESTIMATOR HAD BEEN GIVE
3-4 INCH PER 3HR RATES TO BLOB OF COLD TOP CONVECTION JUST OFFSHORE.
IN THE PAST 1-2HRS...CLOUD TOPS OFFSHORE HAVE SLOWLY WARMED...BUT AT
THE SAME TIME OUTFLOW BOUNDARY HAS NUDGE INTO COASTAL AREAS CENTERED ON
DUVAL...SO WILL BE CONCERNED WITH THIS COUNTY INITIALLY FOR LOCAL FLOOD
POTENTIAL...ESPECIALLY WITH NEW COOLING OCCURRING OVER E DUVAL.
WILL ALSO HAVE TO KEEP AN EYE ON ADJOINING COUNTIES TO THE NORTH AND
SOUTH ALONG THE COAST FOR CONVECTIVE PENETRATION THERE...BUT FOR NOW
SEEMS MOST OF THE ENERGY IS GOING INTO MAINTAINING POTENT MESOSCALE
CONVECTIVE BAND OVER DUVAL.
NOTING THE SHARP PW GRADIENT ALONG THE SE COAST THIS MORNING FROM
MICROWAVE DATA...THE DISTANCE BETWEEN 0.75 INCH PW VALUES ALONG THE NC
COAST AND THE 2.0 INCH PW VALUES ALONG THE N FL/EXT SE GA COASTS WAS
200 MILES.
WILL CONTINUE TO MONITOR...
