DISCUSSION
AN AREA OF HIGH PRESSURE WILL STRENGTHEN OVER THE REGION
THROUGH THE NEXT SEVERAL DAYS, INCREASING THE PRESENCE OF
SUBSIDENCE INVERSIONS ACROSS UTAH. AS SUCH, VERY POOR MIXING AND
LIGHT SURFACE WINDS WILL BE THE RESULT, FAVORING POOR CLEARING
FROM MONDAY THROUGH AT LEAST WEDNESDAY. FLOW PATTERNS WILL
GENERALLY FAVOR DIURNALLY DRIVEN TRENDS, LIKELY HOLDING ONTO A
DOWNSLOPING COMPONENT LONGER DUE TO POOR MIXING. RIDGETOP WINDS
WILL FAVOR A NORTHERLY DIRECTION. THE NEXT POTENTIAL SYSTEM TO
MOVE THROUGH THE REGION WILL BE ON THURSDAY. IF THIS OCCURS IT
WILL MOST LIKELY BE A DRY COLD FRONT, BRINGING OVERALL BETTER
MIXING AND STRONGER WIND SPEEDS THAT MAY TEMPORARILY IMPROVE
CLEARING. UNTIL THEN, ANTICIPATE A STAGNANT, STABLE AIRMASS.
