SPOT FORECAST FOR SECOND DAM
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
219 PM MDT WED JUL 21 2010

.DISCUSSION...MOISTURE ACROSS THE AREA IS EXPECTED TO DECREASE FROM
THE WEST THIS AFTERNOON AS A DISTURBANCE BRUSHING BY TO THE NORTH
PUSHES DRY AIR INTO THE STATE. A WEAK BOUNDARY ASSOCIATED WITH THIS
DISTURBANCE WILL MOVE INTO NORTHERN UTAH OVERNIGHT.

ALTHOUGH THE BEST MOISTURE WILL BE PUSHED EAST OF THE
WILDFIRE LATER THIS AFTERNOON...THERE IS STILL THE POSSIBILITY THAT
ISOLATED STORMS WILL DEVELOP IN THE VICINITY OF THE WILDFIRE THIS
AFTERNOON. IF THESE STORMS DO FORM...WINDS MAY BECOME GUSTY AND
ERRATIC AT TIMES.

HIGH PRESSURE WILL BUILD INTO THE STATE OVERNIGHT...RELAXING WINDS
ENOUGH THAT HAZARDOUS FIRE WEATHER CONDITIONS ARE NOT EXPECTED TO
DEVELOP AGAIN THROUGH THE END OF THIS WEEK. THIS HIGH PRESSURE WILL
REMAIN PARKED OVER THE STATE THROUGH THE END OF THE
WEEK...PREVENTING A NORTHWARD SURGE OF MONSOONAL MOISTURE UNTIL
EARLY NEXT WEEK.
