.
SATELLITE ANALYSIS AND TRENDS...S NV...SINCE 03Z..CONVECTIVE CLOUD TOPS
HAVE BEEN COOLING/EXPANDING OVER SRN LINCOLN/N CLARK COUNTIES. WHILE NRN
EXTENT OF CLOUD TOPS HAVE BEEN SPREADING NWWD PER SERLY UPPR FLOW..SRN
EDGE OF CNVTN OVER N CLARK COUNTY HAS SHOW LTL MOVEMENT. IN FACT..WARM
TOP IR ENHANCEMENT CURVE DOES SHOW SOME CLOUD TOP COOLING/BUILDING TWD
THE SE. AT THE SAME TIME..WARM TOP CELLS OVER S CENTRAL/SW CLARK COUNTY
HAVE BEEN INCRG AND DRIFTING SLWLY NWD. THE CONCERN GOING FORWARD..PER
STLT TRENDS..IS THAT ADDITIONAL CNVTN MAY FILL IN BETWEEN THESE TWO
AREAS. IF THIS TURNS OUT TO BE THE CASE..SOME LOCATIONS COULD EXPERIENCE
SOME CELL MERGING. ALSO OF PSBL CONCERN FOR CLARK COUNTY IS THE EFFECT
OF THE OUTFLOWS FM AZ MCS..AS GOES STLT WINDS SHOWS S TO SERLY FLOW
OVER OVER AZ AND SRN NV. THIS COULD FURTHER ENHANCE THE CNVTN OVER SRN
NV DURING THE OVERNIGHT HRS.
.
GOES SOUNDER DPI IMAGERY SHOWS PW'S RANGING FM 1"PLUS OVER SRN NV TO WELL
1.5" PLUS OVER SW/W/S AZ. DPI ANIMATION INDICATES INCREASINGLY HIGHER
PW'S WILL BE DRAWN INTO S NV. THIS..ALONG WITH STLT TRENDS MENTIONED
ABOVE..RAISES THE POTENTIAL FOR HVY RAINFALL AMOUNTS OVER PARTS OF CLARK
AND SRN LINCOLN COUNTIES OVERNIGHT. SOME LOCATIONS CAN EASILY PICK UP
ADDITIONAL AMOUNTS OF 1-2" IF THIS SCENARIO PLAYS OUT.
.
SW/W AZ...OVERALL INTENSITY OF MCS HAS DECRD..PER CLOUD TOP
WARMING. HOWEVER..A FEW STRONG TSTMS STILL PERSIST OVER N YUMA AND LA
PAZ COUNTIES. THESE STMS HAVE BEEN MOVG. HOWEVER..IMAGERY ANIMATION HAS
SHOWN MERGERS OCCURRING. THUS..STLT RAINFALL ESTIMATES HAVE BEEN AT LEAST
IN THE 1-1.5" RANGE IN AN HOURS TIME..AND WOULD EXPECT THIS CONTINUE TO
BE THE CASE OVER THE NEXT COUPLE OF HRS AS NEW CELLS FORM AND MERGE.
.
CA...WITH OUTFLOW FM MCS PUSHING WWD ACRS AZ/SE CA BORDER..POTENTIAL
EXISTS FOR SOME TSTMS TO FORM OVER ACRS THE BORDER.
