SPOT FORECAST FOR HENRIE KNOLLS
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
840 AM MDT MON JUN 1 2009

.DISCUSSION...HIGH PRESSURE OVER THE AREA IS WEAKENING...AND WILL
MOVE OFF TO THE EAST OVERNIGHT. MOISTURE IS STILL IN PLACE OVER MOST
OF THE STATE...AND MORE AFTERNOON SHOWERS AND THUNDERSTORMS ARE
EXPECTED TODAY. THESE STORMS WILL DEVELOP OVER THE HIGHER
TERRAIN...AND THEN MOVE OVER ADJACENT AREAS. BECAUSE WINDS UNDER THE
HIGH PRESSURE ARE LIGHT...STORMS WILL MOVE SLOWLY. THIS WILL
INCREASE THE CHANCE OF WETTING RAIN FOR THOSE AREAS THAT SEE
CONVECTIVE DEVELOPMENT. WINDS AT THE BURN SITE WILL BE LIGHT AND
TERRAIN DRIVEN. HOWEVER...IF THUNDERSTORMS PASS THROUGH THE
AREA...WINDS WILL BECOME GUSTY AND ERRATIC.

LOW PRESSURE OFF THE CALIFORNIA COAST IS BEGINNING TO MOVE ONSHORE.
THIS WILL RESULT IN A SOUTHWEST FLOW ACROSS THE AREA BEGINNING
TUESDAY. THIS SOUTHWEST FLOW WILL BRING STRONG WINDS AND A DRYING
TREND BEGINNING TUESDAY AND LASTING THROUGH MOST OF THE WEEK.
