SPOT FORECAST FOR SANTA CLARA VEG PILES
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
207 PM MST WED FEB 4 2009

.DISCUSSION...THE RIDGE OF HIGH PRESSURE THAT HAS BEEN OVER THE
REGION THE LAST FEW DAYS WILL MOVE EASTWARD DUE TO A TROUGH OF LOW
PRESSURE MOVING IN THURSDAY. THIS SYSTEM WILL BE WEAKENING AS IT
MOVES INTO UTAH BUT IT WILL BE SUFFICIENTLY STRONG ENOUGH TO SCOUR
OUT MOST VALLEYS. DESPITE PINE VALLEY BEING SOMEWHAT OF A BOX CANYON
BELIEVE THERE WILL BE ENOUGH TURBULENT MIXING FOR YOUR PROJECT TO
HAVE A CLEARING INDEX GREATER THAN 1000. HOWEVER...IT WILL LIKELY
TAKE UNTIL 1300 TO 1400 MST BEFORE THE WINDS DOWN TO THE VALLEY
FLOOR. UNSTABLE CONDITIONS WITH A GOOD CLEARING INDEX ARE EXPECTED
FOR FRIDAY.
