DISCUSSION
A FEW SHOWERS ARE LINGERING THIS EVENING UNDER
OVERALL CYCLONIC FLOW ACROSS THE WESTERN US. AS SHOWERS DWINDLE
OVER THE NEXT FEW HOURS, SKIES WILL CONTINUE TO CLEAR, ALLOWING
TEMPERATURES TO DROP BELOW FREEZING ONCE AGAIN ACROSS SEVERAL
VALLEYS ACROSS THE STATE, NAMELY IRON-BEAVER-MILLARD-JUAB
COUNTIES, SANPETE AND SEVIER VALLEYS, AND THE WESTERN UINTA
BASIN. THIS WILL LIKELY BE THE LAST DAY FOR THESE AREAS TO REACH
BELOW FREEZING FOR AWHILE, AS A WARMING TREND IS EXPECTED THROUGH
AT LEAST THIS WEEKEND.
BROAD CYCLONIC FLOW WILL REMAIN IN PLACE ACROSS THE INTERMOUNTAIN
WEST THROUGH FRIDAY. WITH SOME LINGERING MOISTURE, DAYTIME
HEATING, AND WEAK SHORTWAVE TROUGHS ROTATING THROUGH THE FLOW,
EXPECT CHANCES FOR SHOWERS AND ISOLATED THUNDERSTORMS EACH
AFTERNOON, PRIMARILY OVER HIGHER TERRAIN. INSTABILITY LOOKS TO BE
HIGHEST ON THURSDAY AS THE MAIN COLD CORE SHIFTS OVERHEAD, WITH
THE HIGHEST COVERAGE OF SHOWERS AND THUNDERSTORMS EXPECTED
THURSDAY AFTERNOON, PARTICULARLY ACROSS HIGHER TERRAIN. AS THESE
SHOWERS WILL BE HIGH-BASED, THE MAIN THREAT WILL BE GUSTY AND
ERRATIC OUTFLOW WINDS. ADDITIONALLY, AS RIDGING BUILDS INTO THE
INTERIOR NORTHWEST, EASTERLY FLOW WILL DEVELOP ACROSS NORTHERN
UT/SOUTHWEST WY, POTENTIALLY PRODUCING EASTERLY CANYON WINDS ALONG
THE NORTHERN WASATCH FRONT AND CACHE VALLEY. MODEL GUIDANCE ISN'T
TERRIBLY EXCITED ABOUT ANY DOWNSLOPE WINDS DEVELOPING, THOUGH
LOCAL GUIDANCE SUGGESTS A 10-20% CHANCE OF STRONGER WINDS
DEVELOPING.
OVER THE WEEKEND, HIGH PRESSURE WILL BUILD ACROSS THE AREA,
RESULTING IN EVEN WARMER TEMPERATURES REACHING 5-10 DEGREES ABOVE
NORMAL. HOWEVER, MOISTURE COULD START TO INCREASE AHEAD OF THE
NEXT SYSTEM AS EARLY AS SUNDAY, PERHAPS BRINGING ISOLATED SHOWERS
TO HIGHER TERRAIN SUNDAY AFTERNOON.
NEXT WEEK, OUR ATTENTION TURNS TO A STRONG CLOSED LOW DEVELOPING
OFF THE WEST COAST. TYPICALLY, CLOSED LOW TRACKS CAN BE DIFFICULT
TO FORECAST, BUT MODEL GUIDANCE GENERALLY SUGGESTS THIS LOW TRACKS
INLAND EARLY NEXT WEEK AND ACROSS UT/AZ. THIS SYSTEM DOESN'T
APPEAR TO BE AS COLD AS RECENT STORMS, WITH SNOW LEVELS REACHING
DOWN TO SOMEWHERE BETWEEN 7000-9000FT AS MORE PRECIPITATION
ARRIVES EARLY NEXT WEEK.
