THE FLOW MOVE ACROSS THE AREA. THE STRONGEST DISTURBANCE WILL MOVE
INTO SD THIS EVENING. A FRONTAL BOUNDARY WILL MOVE ACROSS THE AREA
TODAY RESULTING IN COOLER TEMPERATURES THAN THE LAST SEVERAL
DAYS...BUT TEMPS WILL STILL BE ABOVE NORMAL FOR THIS TIME OF YEAR.
SOME MID LEVEL MOISTURE WILL MOVE OVER THE AREA TODAY AND WILL KEEP
A CHANCE OF SNOW ACROSS CARBON COUNTY. THE SNOWY RANGE WILL LIKELY
PICK UP A FEW INCHES OF SNOW BY EVENING. FOR TONIGHT...THE SW FLOW
WILL CONT ALOFT AS AN UPPER TROUGH DEEPENS ACROSS THE WESTERN U.S.
WITH THE NORTHERN AND SOUTHERN BRANCHES BECOMING IN PHASE WITH EACH
OTHER. ON FRI...SW FLOW WILL CONT ALOFT AS ANOTHER DISTURBANCE
MOVES ACROSS THE CWA. THE MAIN UPPER TROUGH AXIS WILL EXTEND FROM
WRN MT TO SRN CA. PRECIP WILL START WEST OF THE LARAMIE RANGE IN
THE MORNING AND WILL SPREAD EAST OF THE LARAMIE RANGE BY AFTERNOON.
PRECIP WILL BE IN THE FORM OF RAIN EAST OF THE LARAMIE RANGE FRIDAY

LONG TERM...SATURDAY THROUGH WEDNESDAY...
SATURDAY WILL BRING AN END TO THE WEEK-LONG PERIOD OF ABOVE

THE COAST OF SAN FRANCISCO IS WRAPPED EASTWARD AND INTO THE LARGER
SCALE TROUGH CURRENTLY OVER BRITISH COLUMBIA. THESE TWO FEATURES
WILL MERGE ALONG THE FRONT RANGE OF SOUTHERN WYOMING AND NORTHERN
COLORADO EARLY SATURDAY WITH SURFACE CYCLOGENESIS OCCURRING ACROSS
EASTERN COLORADO. THIS WILL SUPPORT INCREASED PRECIPITATION
CHANCES ACROSS THE FORECAST AREA SATURDAY WITH THE MID-LEVEL LOW

ARE EXPECTED TO REACH THE UPPER 30S AND LOWER 40S...SO MOST AREAS
CAN EXPECT ANY PRECIPITATION TO MIX RAIN AND SNOW AT LEAST BRIEFLY

DURING THE SATURDAY PERIOD IN THE HIGHER TERRAIN OF THE SNOWY AND
SIERRA MADRE RANGES.
THE EUROPEAN AND GFS MODELS CONTINUE TO SHOW GOOD AGREEMENT SUNDAY
WITH A RETURN TO NEAR NORMAL TEMPERATURES EXPECTED. THE WARMER
TEMPERATURES WILL RESULT FROM A SHORT-WAVE UPPER LEVEL RIDGE WHICH
WILL MOVE OVER WYOMING. THIS FEATURE WILL DEVELOP AHEAD OF THE
NEXT BATCH OF UPPER LEVEL ENERGY WHICH WILL IMPACT THE REGION
EARLY NEXT WEEK. THE NEXT STORM SYSTEM IS CURRENTLY LOCATED OVER
THE BERING STRAITS AND APPEARS TO BE WELL MODELED BY THE GFS AND
EUROPEAN MODELS. THIS WILL LEAD TO A COOLING TREND AND INCREASED
PRECIPITATION CHANCES ACROSS THE AREA MONDAY AND TUESDAY. TUESDAY
WILL BE THE COOLEST DAY OF THE PERIOD WITH NORTHERN AND WESTERN
PORTIONS OF THE AREA STRUGGLING TO REACH THE FREEZING MARK FOR
HIGH TEMPERATURES. HAVE GENERALLY INCREASED PRECIPITATION CHANCES
DURING THE MONDAY AND TUESDAY PERIODS TO REPRESENT GREATER THAN
CLIMATOLOGICAL CHANCES FOR PRECIPITATION. HAVE ALSO INCREASED
PRECIPITATION CHANCES CLOSER TO CLIMATOLOGICAL VALUES FOR
WEDNESDAY...ALTHOUGH MODEL SOLUTIONS SIGNIFICANTLY DIVERGE. THE
GFS INDICATES A RETURN TO NORTHWEST FLOW ALOFT AS A RIDGE BUILDS
ALONG THE PACIFIC COAST...WHILE THE EUROPEAN MODEL SUGGEST A
CONTINUATION OF AN OVERALL TROUGH OVER THE WESTERN UNITED STATES.
