SATELLITE ANALYSIS AND TRENDS...FOR THE PAST FEW HRS..CLOUD TOPS HAVE
BEEN STEADILY COOLING/EXPANDING OVER THE DISCUSSION AREA INDICATING AN
INCR IN COVERAGE AND INTENSITY OF RAINFALL. GOES WV IMAGERY ANIMATION
SHOWS SIGNIFICANT SHARPENING OF SW-NE SHORT WAVE EXTENDING FM VORT MAX S
OF 3HT TO NV. THE CLOUD TOP COOLING HAS COINCIDED WITH THE SHARPENING OF
THE SHORT WAVE WHICH IS PROVIDING INCRG LIFT/UPWARD MOTION OVER THE
DISCUSSION AREA.  AT THE SAME TIME..COPIOUS LOW LEVEL MOISTURE IS BEING
ADVECTED INTO THE REGION BY PERSISTENT SERLY FLOW WITH DEW POINTS IN THE
50S AND PW VALUES RANGING UP TO 0.8" OR MORE.

HOWEVER..HAVE NOTED IMPRESSIVE RAIN RATES REPORTED AT BYG OF 0.74" AT
1541Z. WITH CLOUD TOPS STILL ON A COOLING AND EXPANSION TREND..AND TAKING
INTO ACCOUNT CURRENT CORRESPONDING RAINFALL REPORTS FM BYG AND OTHER
STATIONS..LIKE GCC..EVEN HIGHER RAINFALL RATES CAN OCCUR LATER THIS
MORNING/THIS AFTERNOON..LEAVING OPEN THE POSSIBILITY THAT SOME LOCATIONS
MAY EXPERIENCE.
