DISCUSSION
A BROAD AREA OF HIGH PRESSURE WILL REMAIN IN PLACE OVER THE
EASTERN GREAT BASIN REGION THROUGH AT LEAST TUESDAY OF NEXT WEEK,
FAVORING DRY AND STABLE CONDITIONS OVER THE BURN AREA. PERSISTENT
INVERSIONS ARE LIKELY TO LEAD TO DRY DAYTIME RH FOLLOWED BY POOR
RECOVERY DURING THE OVERNIGHT HOURS, A TREND THAT IS ANTICIPATED
THROUGH AT LEAST TUESDAY AS WELL. BETTER CLEARING INDEX VALUES AND
RH RECOVERIES CAN BE EXPECTED FROM ABOUT WEDNESDAY THROUGH FRIDAY
AS PERSISTENT INVERSIONS WILL BE ALLEVIATED. THAT SAID, ARE
STILL STRUGGLING WITH THE DEPTH OF THE NEXT STORM THAT WILL PASS
THROUGH NORTHERN UTAH, WHICH WILL INFLUENCE HOW MUCH RELIEF FROM
INVERSIONS (AND POOR OVERNIGHT RECOVERY) ARE SEEN ACROSS THE
SOUTH. NO PRECIPITATION IS EXPECTED WITH THIS STORM.
BEYOND THE NEXT STORM, THERE IS GENERALLY HIGH CONFIDENCE THAT
HIGH PRESSURE WILL REMAIN IN PLACE ACROSS THE SOUTHWEST WHICH WILL
HELP TO MAINTAIN DRY AND STABLE CONDITIONS OVER THE BURN AREA.
CURRENT GUIDANCE IS SUPPORTIVE OF THIS AREA OF HIGH PRESSURE
BREAKING DOWN BY AROUND THE 23-25TH OF DECEMBER, POTENTIALLY
INTRODUCING WIDESPREAD MOISTURE INTO THE REGION. UNTIL THEN,
ANTICIPATE DRY CONDITIONS.
