703 AM MDT MON JUN 1 2009

.DISCUSSION...LIGHT SHOWERS ARE INCREASING ACROSS THE PARK THIS
MORNING WITH CLOUD BASES NEAR 12000 FT ABOVE SEA LEVEL. THIS IS
SEVERAL THOUSAND FEET ABOVE THE MOUNTAIN TOPS IN THE PARK. AN
AREA OF HEAVIER SHOWERS AND THUNDERSTORMS IS OVER SOUTHERN NEVADA
AT THIS TIME AND WILL BE SPREADING INTO SOUTHWESTERN UTAH BY LATE
MORNING. THE CLOUD BASES WITH THESE WILL LIKELY BE LOWER AND
COULD OCCASIONALLY OBSCURE THE MOUNTAIN TOPS. RAINFALL FROM THESE
SHOWERS COULD ALSO GENERATE ISOLATED FLASH FLOODING OF THE
SMALLER DRAINAGES. FLOODING IS NOT LIKELY ALONG THE MAIN STEM OF
THE VIRGIN RIVER FROM THESE STORMS ALTHOUGH RISES OF A FOOT OR
TWO ARE POSSIBLE. GUSTY ERRATIC WINDS ARE ALSO LIKELY WITH THE
HEAVIER SHOWERS. THE THREAT OF SHOWERS AND THUNDERSTORMS WILL
CONTINUE INTO TONIGHT BEFORE ENDING. DRIER AIR IS EXPECTED TO
SPREAD INTO THIS AREA TUESDAY AND ANY CLOUDS AND SHOWERS WILL BE
MUCH HIGHER BASED. THIS WOULD BRING A BETTER CHANCE OF GUSTY
ERRATIC WINDS WITH ANY SHOWERS HOWEVER.
