AS SHOWN IN PRECIPITABLE WATER VALUES ON SOUNDING...GOES...AND
ROOFTOP SENSOR...GENERALLY 1.1 INCH OR GREATER. SURFACE DEWPOINT
TEMPS ALSO HIGHER TODAY THAN YESTERDAY OVER THE ENTIRE AREA WHICH
SHOULD RESULT IN LOWER CLOUD BASES AND POTENTIALLY MORE RAIN MAKING
IT TO THE GROUND. YESTERDAY RAINFALL WAS WIDESPREAD BUT GENERALLY
LESS THAN .10 INCH. BETTER CHANCE TODAY FOR HIGHER AMOUNTS.
HOWEVER AIRMASS ALOFT IS STILL QUITE WARM AND INSTABILITY WILL BE
LIMITED. ALSO HAVING A TOUGH TIME FINDING A SPECIFIC FEATURE TO
FOCUS CONVECTION. THERE IS A WELL DEFINED DEFORMATION ZONE OVER THE
NORTH THAT WILL DRIFT NORTHWARD TO THE UT/ID BORDER THIS AFTERNOON
AND THAT WILL LIMIT THE NORTHERN EXTENT OF THE CONVECTION...BUT
OTHERWISE FEATURES ARE ILL DEFINED.
HAVE DECIDED NOT TO ISSUE FLASH FLOOD WATCH AT THIS TIME BUT INSTEAD
WILL MONITOR CONVECTION AND PRECIP AS IT DEVELOPS. LIMITED CAPE MAY
MEAN INTENSE PHASE OF STORMS WILL BE SHORT LIVED...LIMITING HEAVY
RAIN. WILL HAVE TO WAIT AND SEE HOW IT DEVELOPS.
UPDATED ALL ZONES FOR TODAY. INCREASED POPS IN WASHINGTON COUNTY PER
AZ STORMS THAT ARE HEADED THAT WAY RIGHT NOW. HAVE ALSO ACCELERATED
POPS FROM THE AFTERNOON INTO THIS MORNING GIVEN LIGHT SHOWERS THAT

&&
.FIRE WEATHER...SOMEWHAT HIGHER HUMIDITIES HAVE SPREAD INTO SOUTHERN
