.DISCUSSION...PRIMARY CONCERN FOR TODAY AND THE REMAINDER OF THE
WEEK IS ASSOCIATED WITH GUSTY WINDS. UPPER LEVEL TROUGH MOVING
SLOWLY INTO THE GREAT BASIN NUDGED A SURFACE COLD FRONT INTO
NORTHERN UTAH THIS MORNING. HOWEVER...THE FRONT WILL REMAIN NORTH
OF THE BURN AREA LEAVING SOUTHERN UTAH UNDER MOSTLY CLEAR SKIES
THROUGH WEDNESDAY. SOUTH OF THE FRONT GUSTY SOUTHWEST WINDS OF 20
TO 30 MPH WITH GUSTS TO NEAR 45 MPH ARE EXPECTED IN THE VICINITY
OF THE BURN AREA THIS AFTERNOON AND EARLY EVENING. WINDS WILL
DIMINISH BY LATE THIS EVENING BEFORE PICKING BACK UP DURING THE
LATE MORNING ON WEDNESDAY.

THE FLOW ALOFT WILL BE A LITTLE LIGHTER ON WEDNESDAY...ALTHOUGH
BREEZY SOUTHWEST WINDS OF 15 TO 25 MPH WITH GUSTS TO 30 MPH ARE
EXPECTED BY WEDNESDAY AFTERNOON. ALTHOUGH THE FLOW ALOFT IS NOT
AS STRONG AS TODAY...WINDS WILL REMAIN A CONCERN ON THURSDAY AND
FRIDAY ON WEST TO SOUTHWEST FLOW ALOFT. THE FRONT STALLS OUT ACROSS
THE STATE WHICH KEEPS THE WIND POTENTIAL IN PLACE ACROSS SOUTHERN
UTAH INTO THE WEEKEND. MIXING WILL BE EXCELLENT THROUGH THE PERIOD
WITH REASONABLY DEEP MIXING HEIGHTS AND VIGOROUS TRANSPORT WINDS.
HOWEVER...THESE EXCELLENT MIXING CONDITIONS WILL BE ASSOCIATED
WITH GUSTY WINDS AT THE SURFACE.
