SATELLITE ANALYSIS AND TRENDS...LATEST VIS IMAGERY SHOWS THE REMNANTS
OF AN MID-LVL CYCLONIC CIRCULATION SPINNING ACROSS S NV AND ALONG WITH
DAYTIME HEATING..WILL LIKELY BE THE FOCAL POINT FOR THIS AFTERNOONS
HVY RAINS.  SOME CU ARE ALREADY BEGINNING TO BUILD ACROSS S NV/N AZ/SW
UT AT THIS HR.  GOES WV ANIMATION SHOWS ADDITIONAL MID-LVL MOISTURE
SURGING NWD OUT OF NW MEXICO AND INTO S AZ/SW CA.  THIS SAME SURGE OF
HIGHER MOISTURE IS ALSO BEING SEEN AT LLVLS PER GOES SOUNDER PW VALUES
(1.5-1.6" OVER NW MEXICO).  THIS ADDITIONAL MID-LVL MOISTURE IS EXPECTED
TO CONTINUE TO BE DRAWN NWD..BRINGING IT CLOSER TO THE MID-LVL CIRCULATION
OVER S NV WHERE IT WILL ONLY COMPOUND THE THIS ANTICIPATED HVY RAINFALL
THREAT THIS AFTERNOON.
.
AT THE SFC..OBJECTIVE ANALYSIS OF THETA-E SHOWS THE AXIS NOSING INTO
PORTIONS OF SW NV/S UT.  ADDITIONALLY..AREA OF BEST SFC MOISTURE
CONVEGENCE IS ANALYZED AT 18Z TO BE ACROSS SW UT.  CURRENT THINKING
IS THAT GREATEST LIKELIHOOD WHERE HVY RAINS ARE EXPECTED TO BE
THE MOST WIDESPREAD ARE ACROSS PORTIONS OF TULANE/INYO COUNTIES IN
CA.. NYE/LINCOLN/CLARK COUNTIES IN S NV..MOHAVE/N COCONINO COUNTIES IN
NW AZ..WASHINGTON/KANE/IRON/GARFIELD/BEAVER/PIUTE/WAYNE COUNTIES IN S UT.
