NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1157 AM MST TUE NOV 13 2012

.DISCUSSION...HIGH PRESSURE IS IN PLACE OVER THE SOUTHWESTERN UNITED
STATES FOR THE BEGINNING OF THIS WEEK...LEADING TO LIGHT WINDS
AND POOR MIXING. SOUTHERLY WINDS WILL INCREASE A BIT FOR THURSDAY
AHEAD OF A STORM SYSTEM OVER THE WEST COAST...BUT CLEARING
INDICES AT THE BURN SITE ARE CURRENTLY EXPECTED TO BE IN THE
300-400 RANGE FOR THURSDAY AFTERNOON.

MIXING AND WINDS SHOULD BOTH INCREASE SIGNIFICANTLY FOR FRIDAY AS
A WEAK STORM SYSTEM MOVES THROUGH THE AREA...WITH CLEARING
INDICES LIKELY NEAR 1000. MOISTURE WILL ALSO INCREASE WITH THIS
STORM...LEADING TO HIGHER RELATIVE HUMIDITY VALUES AND A CHANCE
FOR PRECIPITATION. ANY PRECIPITATION IS CURRENTLY FORECAST TO BE
LIGHT...WITH NO SIGNIFICANT SNOW ACCUMULATIONS EXPECTED. SIMILAR
MOIST AND UNSETTLED CONDITIONS ARE LIKELY FOR SATURDAY AND SUNDAY
AS WELL. THE BEGINNING OF NEXT WEEK IS SOMEWHAT UNCERTAIN AT THE
MOMENT...BUT GOOD MIXING IS POSSIBLE FOR MONDAY AND TUESDAY.
