.DISCUSSION...PRIMARY CONCERN FOR TODAY AND THE REMAINDER OF THE
WEEK REVOLVES AROUND GUSTY WINDS. UPPER LEVEL TROUGH MOVING SLOWLY
INTO THE GREAT BASIN TODAY HAS PUSHED A COLD FRONT INTO NORTHERN
UTAH. THE FRONT WILL REMAIN NORTH OF THE BURN AREA LEAVING THE
BURN UNDER MOSTLY CLEAR SKIES THROUGH WEDNESDAY. HOWEVER...GUSTY SOUTHWEST
WINDS OF 20 TO 30 MPH WITH GUSTS TO NEAR 45 MPH ARE EXPECTED THIS
AFTERNOON AND EARLY THIS EVENING. WINDS WILL DIMINISH OVERNIGHT
BEFORE PICKING BACK UP IN THE LATE MORNING ON WEDNESDAY. AS THE
FLOW ALOFT DECREASES A BIT...WINDS WILL NOT BE QUITE A STRONG ON
WEDNESDAY NEAR THE BURN. HOWEVER...WINDS WILL STILL BE BREEZY WITH
15 TO 25 MPH AND GUSTS TO 30 MPH EXPECTED. MIXING WILL BE
EXCELLENT THROUGH THE END OF THE WEEK AS A RESULT OF DEEP MIXING
AND STRONG TRANSPORT WINDS. HOWEVER..THESE EXCELLENT MIXING
CONDITIONS WILL BE ASSOCIATED WITH GUSTY WINDS AT THE SURFACE.
