IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.
DISCUSSION
A BROAD AREA OF HIGH PRESSURE WILL REMAIN IN PLACE
ACROSS CENTRAL UTAH THROUGH THE NEXT SEVERAL DAYS, LEADING TO DRY
AND STABLE CONDITIONS. STABLE CONDITIONS WILL BRING POOR CLEARING
THROUGH THE WEEK DUE TO LIMITED MIXING HEIGHTS AND WEAK TRANSPORT
WINDS OVER THE BURN AREA. AS HIGH PRESSURE DOMINATES THE AREA,
LIGHT WINDS WILL BE PREVALENT EACH DAY, FAVORING TERRAIN DRIVEN
FLOW PATTERNS. THERE IS GENERALLY HIGH CONFIDENCE THAT THIS AREA
OF HIGH PRESSURE WILL REMAIN IN PLACE THROUGH THE NEXT 7 TO 8 DAYS
AT LEAST, KEEPING A SIMILAR TREND OF POOR CLEARING AND NO
PRECIPITATION THROUGH THIS PERIOD.
