EVENT...INCREASING HEAVY RAIN THREAT
.
SATELLITE ANALYSIS AND TRENDS...LATEST WATER VAPOR IMAGERY DEPICTS A
VORT MOVING NORTHWARD ACROSS FRONTAL BOUNDARY IN N GULF AT THIS TIME
THAT HAS HELPED INCREASE UPPER LEVEL DIVERGENCE/LIFT LAST FEW HOURS.
IR IMAGERY AT THIS TIME HAS SHOWN DEEPEST CONVECTION OFFSHORE BUT THERE
HAS BEEN SOME CELL DEVELOPMENT INVOF DIXIE COUNTY WHERE SFC OBS HAVE
SHOWN RATES AS HIGH AS 1.5"/HR. PLENTY OF MOISTURE ACROSS THE DISCUSSION
REGION WITH PWATS AT OR ABOVE 2.2" AND EVEN SOME 2.5" MAXES WEST OF
DISCUSSION REGION OVER THE GULF PER NESDIS BLENDED TPW PRODUCT. WITH SPC
MESOANALYSIS PLACING 1000-1500 J/KG OF BEST CAPES ACROSS N GULF COUPLED
WITH SFC BOUNDARY WOULD EXPECT SHOWER ACTIVITY TO CONTINUE NEXT 3 HOURS
WITH RATES OF 1-2"/HR IN DEEPEST CORES/CONVECTION. WOULD EXPECT RAIN
THREAT TO INCREASE TOWARDS END OF OUTLOOK PERIOD AS DAY TIME HEATING
WILL HELP INCREASE INSTABILITY. COORDINATION WITH WPC METWATCH HAS BEEN
ONGOING WITH THIS EVENT.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 0930-1230Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...EXPECT INCREASED SHOWER ACTIVITY ACROSS DISCUSSION
REGION WITH RATES AS HIGH AS 1-2"/HR POSSIBLE IN BEST SHOWERS. WITH 3
HR FFG AT OR ABOVE 4" WOULD NOT EXPECT MORE THAN A MEDIUM THREAT FOR FF
ISSUES IN THE SHORT TERM. HOWEVER IT IS ANTICIPATED THAT SLOW MOVING
SHOWERS COULD POSE A THREAT TOWARDS END OF OUTLOOK AS SHOWER ACTIVITY
IS EXPECTED TO BECOME BETTER ORGANIZED LATER THIS MORNING.
