TUESDAY, CURBING THE WARMING TREND AND BRINGING A VERY LOW

DISCUSSION
HIGH PRESSURE REMAINS IN PLACE OVER UTAH THIS
EVENING, THOUGH SLIGHTLY FLATTENED DUE TO A TROUGH CROSSING THE
IDAHO PANHANDLE AND HEADING INTO MONTANA. THE HIGH PRESSURE WILL
REBOUND OVER UTAH OVER THE WEEKEND, WITH GREATEST HEIGHTS ON
SUNDAY. PATCHY HIGH CLOUDS WILL CONTINUE CROSSING THE REGION
THROUGH SATURDAY, OTHERWISE DRY AND STABLE CONDITIONS CAN BE
EXPECTED UNDER THIS PATTERN. TEMPERATURES WILL VERY GRADUALLY
TREND WARMER THROUGH SUNDAY.
ON MONDAY, THE RIDGE AXIS WILL SHIFT EAST AS A WEAKENING TROUGH
MOVES INTO THE GREAT BASIN. THIS TROUGH IS EXPECTED TO CROSS UTAH
MONDAY NIGHT INTO TUESDAY. EXPECT GENERALLY LITTLE IMPACT FROM
THIS TROUGH. LATEST MODELS CONTINUE TO TREND LOWER ON QPF. THE NBM
75TH PERCENTILE HAS MOSTLY 0 QPF ACROSS UTAH WITH THIS TROUGH,
WITH LESS THAN 0.05 INCHES OVER THE UINTAS. TEMPERATURES SHOULD
DROP SLIGHTLY BY TUESDAY. HIGH PRESSURE IS THEN PROGGED TO BUILD
BACK INTO THE AREA FOR THE SECOND HALF OF NEXT WEEK.
SOUTHWEST FLOW MAY INCREASE NEXT WEEKEND AHEAD OF A POTENTIALLY
DEEPENING TROUGH. HOWEVER, WHILE THE MAJORITY OF GLOBAL ENSEMBLES
DEPICT SOME SORT OF TROUGH MOVING INTO UTAH LATE NEXT WEEKEND OR
EARLY NEXT WEEK, CLUSTER ANALYSIS OF GLOBAL ENSEMBLES CURRENTLY
SHOW APPRECIABLE MODEL SPREAD IN TERMS OF THE STRENGTH AND TIMING
OF ANY SUCH TROUGH.
