DISCUSSION
THE FRONTAL BOUNDARY THAT HAS BEEN STALLED OVER
NORTHERN UTAH IS WEAKENING AND PUSHING EAST THIS EVENING WITH THE
ARRIVAL OF SOME SHORTWAVE ENERGY. THUS, COVERAGE OF PRECIPITATION
HAS DIMINISHED CONSIDERABLY, WITH ISOLATED SHOWERS CURRENTLY
FOCUSED OVER WESTERN UTAH IN ASSOCIATION WITH SOME WEAK EMBEDDED
SHORTWAVES. REMAINING STORMS AND MUCH OF THE ASSOCIATED CLOUD
COVER IS EXPECTED TO DIMINISH OVERNIGHT, ALLOWING TEMPERATURES TO
TUMBLE BELOW FREEZING FOR MANY VALLEYS AWAY FROM THE WASATCH FRONT
FOR TUESDAY MORNING. GOING FREEZE WARNINGS COVER THE CURRENT
THREAT WELL.
TEMPERATURES WILL BEGIN THEIR WARMING TREND TOMORROW, THOUGH MAXES
WILL AVERAGE 5F BELOW SEASONAL NORMALS. LINGERING COOLER AIR WILL
BRING MORE FREEZING TEMPERATURES TO THE UINTA BASIN AS WELL AS
CENTRAL AND SOUTHWEST UTAH VALLEYS. BY MIDWEEK, HOWEVER,
TEMPERATURES WILL RETURN TO NEAR NORMAL FOR THIS TIME OF YEAR,
SUBSTANTIALLY DECREASING THE THREAT OF FREEZING TEMPERATURES FOR
VALLEY LOCATIONS. CONTINUED UNSETTLED WEATHER WILL BRING A FEW
AFTERNOON SHOWERS TO THE HIGHER TERRAIN, FOCUSED OVER FAR NORTHERN
UTAH ON TUESDAY AND SPREADING THROUGH THE REMAINDER OF THE
NORTHERN AND CENTRAL MOUNTAINS ON WEDNESDAY, WITH MUCH OF THE
GUIDANCE SHOWING ANOTHER WEAK SHORTWAVE MOVING THROUGH.
CONFIDENCE IS STARTING TO INCREASE IN THE POTENTIAL FOR A MORE
SUBSTANTIAL BUT STILL RELATIVELY WEAK SHORTWAVE TO IMPACT THE AREA
THURSDAY. THIS SYSTEM WOULD TEMPORARILY CURB THE WARMING TREND AND
BUMP THE COVERAGE OF AFTERNOON CONVECTION OVER THE HIGHER TERRAIN
INTO THE SCATTERED RANGE, BUT OVERALL IMPACTS WOULD BE RELATIVELY
LIMITED.
BEHIND THAT TROUGH, CONFIDENCE IS HIGHER THAN USUAL IN THE RETURN
OF HIGH PRESSURE FRIDAY THROUGH AT LEAST THE UPCOMING WEEKEND.
THIS WOULD MOVE MUCH DRIER AIR IN AND BRING MORE SUBSTANTIAL
WARMING, WITH A HIGH CHANCE OF MAXES RUNNING 10F OR MORE ABOVE
SEASONAL NORMALS BY EARLY NEXT WEEK.
