...SUMMARY...
ORGANIZED SEVERE STORMS ARE NOT EXPECTED OVER THE CONTIGUOUS UNITED
STATES TONIGHT.

...S-CNTRL/SERN AZ...
SCATTERED PULSE-TYPE CONVECTION MAY YIELD STRONG WIND GUSTS WITHIN
EMBEDDED MICROBURSTS THROUGH THIS EVENING. 00Z TUS RAOB SAMPLED
LITTLE CHANGE FROM YESTERDAY WITH A MODESTLY UNSTABLE AND DEEP-MIXED
BOUNDARY LAYER...BUT WITHIN EFFECTIVE SHEAR OF ONLY AROUND 10 KT.
VWP DATA FROM KIWA CONFIRMS THE WEAK 0-6 KM SHEAR ENVIRONMENT
EXTENDS NW TO THE PHOENIX METRO. WHILE THE LARGEST SURFACE
TEMPERATURE/DEW POINT SPREADS PERSIST WITHIN THIS AREA...THE WRN
EXTENT OF CONVECTIVE DEVELOPMENT IN VISIBLE SATELLITE IMAGERY ALONG
THE AZ/SONORA BORDER IS SOMEWHAT LESS THAN ON SUN EVENING. WHILE A
HIGHLY LOCALIZED DAMAGING WIND EVENT IS NOT ENTIRELY
NEGLIGIBLE...THE SMALL PROBABILITY OF THIS OCCURRING APPEARS TOO LOW
TO WARRANT CONTINUING A MARGINAL RISK DELINEATION.
