SYNOPSIS
HIGH PRESSURE WILL BRING DRY CONDITIONS WITH A STEADY
WARMING TREND THROUGH THANKSGIVING DAY. UTAH AND SOUTHWEST WYOMING
WILL SEE MORE UNSETTLED CONDITIONS FRIDAY THROUGH THE WEEKEND WITH
THE POTENTIAL FOR SNOW.
DISCUSSION
SEEING MOSTLY CLEAR SKIES AND LIGHT WINDS ACROSS
UTAH AND SOUTHWEST WYOMING THIS AFTERNOON UNDER THE INFLUENCE OF
HIGH PRESSURE CENTERED OFF THE CALIFORNIA COAST. THE GRAZING STORM
SYSTEM HAS MOVED WELL EAST OF THE AREA, BUT HAS BROUGHT A MODEST
COOLDOWN WITH HIGHS RUNNING NEAR SEASONAL NORMALS ACROSS THE AREA. THE
RIDGE WILL BE THE DOMINANT WEATHER FEATURE ACROSS THE AREA FOR
MUCH OF THE WEAK. IT IS EXPECTED TO SLOWLY SHIFT EAST, WITH THE
AXIS MOVING OVERHEAD ON THANKSGIVING DAY, FORECAST TO BE THE MOST
MILD DAY OF THE WEEK WITH MAXES AVERAGING 10F ABOVE SEASONAL
NORMALS.
CONFIDENCE IS HIGH THAT THE RIDGE WILL MOVE EAST OF THE AREA
FRIDAY AS A PACIFIC NORTHWEST STORM SYSTEM MAKES ITS WAY ONSHORE.
ABOUT THE DETAILS, HOWEVER, CONFIDENCE LOWERS SIGNIFICANTLY. THIS
AFTERNOON, THE MOST COMMON SOLUTION SHOWS THIS INITIAL SYSTEM
MOVING ACROSS NORTHERN PORTIONS OF THE AREA LATE FRIDAY INTO EARLY
SATURDAY AS A GRAZING SYSTEM, RESULTING IN A SMALL CHANCE OF LIGHT
SNOW FOR THE MOUNTAINS OF NORTHERN UTAH. ENSEMBLE SPREAD INCREASES
FURTHER WITH THE TRAILING SYSTEM BEHIND THE INITIAL WAVE. A CUT
OFF OVER THE DESERT SOUTHWEST FOR SUNDAY IS MOST FAVORED, BUT A
SOLUTION WHERE THIS WAVE MOVES ACROSS NORTHERN UTAH IN A MUCH MORE
WEAKENED STATE HAS GAINED SOME POPULARITY. OVERALL, GUIDANCE IS
MOVING AWAY FROM SOLUTIONS THAT WOULD PRODUCE MORE SIGNIFICANT
ACCUMULATIONS, SO FORECAST SNOW TOTALS HAVE GONE DOWN
SIGNIFICANTLY. HIGH PRESSURE IS THEN LIKELY TO RETURN EARLY NEXT
WEEK.
