SPOT FORECAST FOR GREEN HILLS PILES
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
513 AM MDT MON APR 26 2010

.DISCUSSION...HIGH PRESSURE WILL CONTINUE TO BUILD ACROSS THE
AREA TODAY...LEADING TO WARMING TEMPERATURES AND MOSTLY CLEAR
SKIES. WINDS FOR TODAY AND TONIGHT WILL PRIMARILY BE LIGHT AND
TERRAIN DRIVEN...WITH UPSLOPE/UPVALLEY WINDS DURING THE DAY AND
DOWNSLOPE/DOWNVALLEY WINDS AT NIGHT...BUT THESE NATURAL FLOWS MAY
BE ENHANCED SLIGHTLY BOTH TODAY AND TONIGHT...LEADING TO
SUSTAINED WINDS AS STRONG AS ABOUT 10 MPH.

SOUTHERLY WINDS WILL INCREASE DRAMATICALLY ACROSS THE STATE
ON TUESDAY AHEAD OF AN APPROACHING COLD FRONT. SUSPECT THE
SHELTER PROVIDED BY OGDEN VALLEY WILL MAKE WINDS SOMEWHAT WEAKER
AND MORE SOUTHWESTERLY AT THE BURN SITE ON TUESDAY. THAT BEING
SAID...THE POTENTIAL FOR STRONG GUSTS STILL EXISTS ON TUESDAY
AFTERNOON...WITH GUSTS IN THE 40S OR EVEN 50S POSSIBLE AT THE
BURN SITE BY LATE TUESDAY AFTERNOON. THE COLD FRONT SHOULD ARRIVE
EARLY WEDNESDAY MORNING...SWITCHING WINDS TO THE NORTHWEST AND
LIKELY BRINGING WETTING RAIN AND SNOW TO THE BURN SITE...WITH
SNOW LEVELS QUICKLY DROPPING BELOW 5000 FEET.
