SPOT FORECAST FOR STEEP CREEK
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
710 PM MDT SUN JUL 19 2009

.DISCUSSION...A RIDGE OVER THE AREA IS BEGINNING TO
FLATTEN...ALLOWING UPPER LEVEL MOISTURE TO MOVE INTO THE AREA.
HOWEVER...WITH DRY AIR STILL PRESENT NEAR THE SURFACE...THIS
MOISTURE IS EXPECTED TO RESULT IN HIGH BASED THUNDERSTORMS THIS
EVENING....ESPECIALLY OVER THE HIGHER TERRAIN. BECAUSE OF THE
DRY LOWER LEVELS...LITTLE PRECIPITATION IS EXPECTED TO REACH THE
GROUND WITH THESE THUNDERSTORMS. INSTEAD...THE MAIN THREAT WILL BE
DRY LIGHTNING WITH STRONG GUSTY AND ERRATIC WINDS IN THE VICINITY
OF THUNDERSTORMS. THIS MOISTURE IS EXPECTED TO LINGER THROUGH THE
WEEK...WITH THE LOW LEVEL MOISTURE INCREASING DURING THE EARLY
WORK WEEK. AS THE LOW LEVEL MOISTURE INCREASES...THE CHANCE OF
WETTING RAIN WILL INCREASE.
