DISCUSSION
VALLEY RAIN AND MOUNTAIN SNOW SHOWERS ARE ONGOING
THIS MORNING ACROSS PRIMARILY NORTHERN UTAH, LOCATED JUST BEHIND
A WEAK BOUNDARY ASSOCIATED WITH AN APPROACHING SHORTWAVE TROUGH.
THIS AREA OF SHOWERS, LIKELY BECOMING A BIT STRONGER WITH DAYTIME
HEATING, WILL LIKELY STALL THIS AFTERNOON ALONG A WEST-EAST
ORIENTED LINE ROUGHLY NORTH OF RICHFIELD AND SOUTH OF SALT LAKE
COUNTY BEFORE THE AFOREMENTIONED SHORTWAVE EJECTS ACROSS THE STATE
THIS EVENING, PUSHING THE LINE SOUTHWARD. ISOLATED THUNDERSTORMS
ARE POSSIBLE THIS AFTERNOON, WITH BRIEF PERIODS OF MODERATE-HEAVY
PRECIPITATION RATES GIVEN LINGERING LOW- TO MID-LEVEL MOISTURE.
BEHIND THE BOUNDARY, CONDITIONS WILL DRY OUT AND SKIES WILL BEGIN
TO CLEAR UP WITH SHOWERS LARGELY ENDING BY MIDNIGHT, OR EVEN
SOONER. MID- TO HIGH-LEVEL CLOUDS WILL CLEAR, RESULTING IN COOLER
TEMPERATURES OVERNIGHT WITH MANY VALLEYS DIPPING BELOW FREEZING.
AS SUCH, FREEZE WATCHES HAVE BEEN UPGRADED TO FREEZE WARNINGS. ONE
FORECAST PROBLEM IS THE EXTENT OF LINGERING LOW CLOUDS NEAR
HIGHER TERRAIN OVERNIGHT, WHICH COULD LIMIT THE DEGREE OF COOLING,
PARTICULARLY CENTRAL VALLEYS LIKE THE SANPETE AND SEVIER VALLEYS.
TOMORROW, ALTHOUGH TEMPERATURES WILL BEGIN TO INCREASE ACROSS THE
REGION, MANY VALLEYS ARE EXPECTED TO REACH FREEZING ONCE AGAIN BY
EARLY WEDNESDAY MORNING, WITH FREEZE WARNINGS EXTENDED
ACCORDINGLY.
CONDITIONS WILL LARGELY BE QUIETER FOR THE REST OF THE WEEK,
THOUGH MODESTLY CYCLONIC FLOW AND DAYTIME HEATING MAY RESULT IN
ISOLATED AFTERNOON MOUNTAIN SHOWERS ACROSS NORTHERN UTAH EACH DAY.
ON THURSDAY, AREAL COVERAGE OF THESE SHOWERS MAY EXPAND INTO
SOUTHERN UTAH AS A SHORTWAVE TROUGH SWINGS THROUGH THE REGION,
THOUGH MOISTURE WILL STILL BE PRETTY LIMITED OVERALL.
TEMPERATURES WILL STEADILY INCREASE THROUGH SUNDAY, PARTICULARLY
AS HIGH PRESSURE BUILDS THIS WEEKEND. FORECAST HIGHS WILL RISE
FROM 5-15 DEGREES BELOW NORMAL TODAY TO 5-10 DEGREES ABOVE NORMAL
BY SUNDAY. HOWEVER, MODEL GUIDANCE FAVORS MORE ACTIVE WEATHER
RETURNING AS EARLY AS MONDAY WITH OVERALL CONSENSUS POINTING
TOWARDS LOWERING 500-MB HEIGHTS NEXT WEEK.
