SPOT FORECAST FOR WILLOW CREEK
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
352 PM MDT SAT MAY 30 2009

.DISCUSSION...HIGH PRESSURE OVER THE AREA WILL GRADUALLY WEAKEN
BEFORE MOVING TO THE EAST EARLY NEXT WEEK. LIGHT WINDS AND
RELATIVELY MOIST AIR WILL PERSIST WHILE THE HIGH PRESSURE REMAINS
OVERHEAD. THIS MOISTURE WILL RESULT IN AFTERNOON SHOWERS AND
THUNDERSTORMS THAT DEVELOP OVER THE HIGHER TERRAIN. BECAUSE OF THE
LIGHT WINDS...THUNDERSTORMS WILL MOVE SLOWLY...INCREASING THE CHANCE
OF WETTING RAIN OVER THE AREAS THAT SEE CONVECTIVE DEVELOPMENT.
WHILE WINDS WILL BE GENERALLY LIGHT AND TERRAIN DRIVEN THROUGH
MONDAY... A THUNDERSTORM IN THE AREA WOULD PRODUCE STRONG...GUSTY
WINDS.

BEYOND THIS...A STRONGER SOUTHWEST FLOW IS EXPECTED TO BEGIN TUESDAY
MORNING...BRINGING A DRYING TREND TO THE REGION.
