EVENT...MOISTURE AND HEATING FOR FF THREATS MOSTLY WEST AND CENTRAL...
.
SATELLITE ANALYSIS AND TRENDS...LATEST MICROWAVE AND BLENDED TOTAL PW
LOOP SHOWED CONCENTRATION OF MOISTURE WITH FRONTAL BOUNDARY STILL OVER THE
ISLAND...BUT  DEFINITELY HIGHER VALUES THE FURTHER WEST ACROSS THE ISLAND.
DAYTIME HEATING AND MOUNTAIN CONVERGENCE/OROGRAPHIC LIFT HAS HELPED THIS
AFTERNOON'S STORMS GET GOING WITH LATEST MERGER COOLING TOP TO -46C OR
TO 225MB.  THIS STILL BELOW THE EQUILIBRIUM LEVEL TEMP FROM 12Z FO 161MB
OR -60C...SO THAT SHOULD ALSO BE A GUIDE TO CRITICAL FF THREAT IF TEMP
STARTS GETTING CLOSE TO THAT FIGURE NEXT 1-2HRS.  AND THAT MAY ALREADY
BE HAPPENIGN IN MOROVIS/CIALES BECAUSE SATELLITE SENSOR RESOLUTION CAN
NOT PICK UP THE FULL INTENSITY OF LATEST MERGER CELLS OVER CENTRAL PART
OF THE ISLAND.  BOUNDARIES AND WHERE THEY INTERSECT WILL ALSO PLAY A
BIG ROLE IN FF THREAT IN WESTERN HALF OF ISLAND NEXT FEW HRS...WILL KEEP
AN EYE ON THAT AS HIGH PW MOISTURE IN A MESOSCALE SENSE CAN POOL TOWARD
THESE INTERSECTING BOUNDARIES.
