NATIONAL WEATHER SERVICE GRAND JUNCTION CO
1001 PM MST SUN FEB 2 2014
.UPDATE...
ISSUED AT 614 PM MST SUN FEB 2 2014
UPGRADED THE WINTER STORM WATCHES TO WARNINGS FOR OUR CENTRAL AND
SOUTHERN MOUNTAIN ZONES OF WESTERN COLORADO AND THE MOUNTAINS OF
SE UTAH. THIS WAS MAINLY DONE BECAUSE THE ONSET TIMES FOR SNOWFALL
WILL OCCUR DURING THE FIRST PERIOD...LATER TONIGHT. FORECAST
SNOWFALL AMOUNTS FOR THE WARNED MOUNTAIN ZONES STILL SEEM
REASONABLE.
WILL NEED TO TAKE A LOOK AT SOME OTHER ZONES WHERE WE PRESENTLY
HAVE BORDERLINE ADVISORY CRITERIA SNOWFALL AMOUNTS IN THE
FORECAST.

.SHORT TERM...(TONIGHT THROUGH MONDAY NIGHT)

TWO WEATHER SYSTEMS BLEND TOGETHER TO FORM THE NEXT WINTER STORM
TO IMPACT THE REGION. IN THE NEAR TERM...THE CIRCULATION OVER
CENTRAL CALIFORNIA IS PROGGED TO DROP SOUTHEAST INTO ARIZONA ON
MONDAY. A DEFORMATION ZONE DEVELOPS OVER WEST CENTRAL COLORADO
WHERE THE NRN AND SRN STREAM MEGRE. HIGH CLOUDS SPREAD FROM THE
SOUTHWEST THIS EVENING WITH THE MID LEVEL MOISTURE ARRIVING LATE
TONIGHT. THE RAP MODEL SHOWS THE THREAT OF SNOW IN THE WESTERN
SLOPE MOUNTAIN BEGINNING AFTER MIDNIGHT...BUT DYNAMICAL ASCENT
DOES NOT REACH SOUTHWEST COLORADO UNTIL MONDAY MORNING. SNOW
EXPANDS AND ENCOMPASSES THE MOUNTAIN AREAS BY NOONTIME MONDAY.
STATIC STABILITY IS LOW WITH MODEL DATA DEPICTING SOME CAPE
VALUES. THIS SUGGESTS THAT DEVELOPING SNOW CLOUDS WILL HAVE SOME
UPDRAFTS THAT SHOULD ENHANCE THE OROGRAPHIC AND DYNAMICAL
COMPONENTS. SURFACE PROGS SHOWS A BROAD AREA OF LOW PRESSURE
CENTERED OVER SOUTHWEST COLORADO. GIVEN THESE FACTORS...BELIEVE
THAT HOISTING THE WINTER STORM WATCH IS THE PRUDENT THING TO DO.
HIGH COUNTRY QPF VALUES SUPPORT AREAS OF WARNING CRITERIA BEING
REACHED BY TUESDAY AFTERNOON. EXPECT SOME SNOW TO EXPAND INTO THE
LOWER VALLEYS AND LATER SHIFTS MAY NEED TO CONSIDER ADDING WINTER
WEATHER ADVISORIES.
.LONG TERM...(TUESDAY THROUGH SUNDAY)
ISSUED AT 308 PM MST SUN FEB 2 2014
AN AMPLIFIED EASTERN PACIFIC/ALASKAN RIDGE IN THE WEST AND A STRONG
BERMUDA HIGH OVER THE CARIBBEAN WILL KEEP A BROAD...ACTIVE TROF
ACROSS MUCH OF THE CONUS THIS WEEK. THE PACIFIC JET IN THE BASE OF
THIS TROF WILL DIVE FROM THE PACIFIC NORTHWEST INTO THE DESERT
SOUTHWEST BEFORE ARCING BACK INTO THE UPPER MIDWEST THROUGH MUCH OF
THIS PERIOD. MORE ORGANIZED PIECES OF ENERGY MOVING THROUGH THE FLOW
WILL FORCE THE JET TO BECOME MORE CYCLONICALLY CURVED NEAR THE 4
CORNERS AT EACH END OF THE NEW WORK WEEK...WHICH WILL ADD SOME
ADDITIONAL ASCENT OVER OUR REGION. WITH THE JET TO OUR
SOUTH...COLD TEMPERATURES WILL BE IN PLACE. THIS COULD LEAVE HIGH
TEMPERATURES SOME 20 DEGREES BELOW NORMAL ACROSS PORTIONS OF THE
CWA. PIECES OF UNORGANIZED AND ORGANIZED ENERGY AND PACIFIC
MOISTURE PUSHED ALONG WITH THE JET WILL ALSO BRING PERIODS OF
SNOW...HEAVY AT TIMES...TO OUR CWA MOUNTAINS WITH VALLEYS LIKELY
TO SEE SOME WHITE STUFF AS WELL.
TUESDAY MORNING THE FIRST OF THE MORE ORGANIZED SYSTEMS WILL BE OVER
THE CWA. THE PACIFIC WAVE WILL HAVE MOVED INTO THE SOUTHERN PLAINS
BY SUNRISE...BUT THE UPSTREAM ARCTIC WAVE WILL BE SWINGING ACROSS
THE WYOMING AND NORTHERN COLORADO ROCKIES THROUGH THE DAY. 290K
MOISTURE TRANSPORT VECTORS SHOW THIS WAVE BRINGING IN ADDITIONAL
MOISTURE AND PWAT TOPS OUT AT NEAR .25 INCH. THIS IS HALF OF LAST
WEEK BUT WITH STRONGER INSTABILITY IN PLACE...IT SHOULD BE ABLE TO
CONTINUE THE THREAT OF MODERATE TO HEAVY MOUNTAIN SNOW SHOWERS
THROUGH THE DAY. CROSS SECTIONS SHOW NEG EPV NEAR MOUNTAIN LEVEL
WITH WESTERLY OROGRAPHICS HELPING TO RELEASE THIS INSTABILITY.
MODELS ALSO SUGGEST THIS WAVE WILL BE GIVING THE TRUE ARCTIC FRONT
A SHOVE SOUTHWARD INTO NORTHWEST COLORADO THROUGH THE AFTERNOON.
TEMPERATURES COULD VERY WELL BE DROPPING THROUGH THE MID TEENS
NORTH OF HIGHWAY 40 AFTER MID DAY. THIS FRONT WOULD ALSO SERVE AS
ADDITIONAL LOW LEVEL FOCUS FOR SNOW IN THE NORTHERN VALLEYS WHERE
DENDRITIC TEMPERATURES WILL BECOME MORE FAVORABLE FOR LOW DENSITY
SNOW PRODUCTION.
A SHORT LULL CAN BE EXPECTED LATE TUESDAY NIGHT INTO WEDNESDAY
MORNING IN THE WAKE OF THIS WAVE. THETA SURFACES REVEAL PACIFIC
MOISTURE ENTRAINING IN THE FLOW OVER THE GREAT BASIN. FAVORABLE
OROGRAPHICS THROUGH A SATURATED DENDRITIC LAYER OVER THE HIGH
COUNTRY LOOKS TO KEEP LIGHT SNOW PROCESSES GOING...WITH AFTERNOON
INSTABILITY BOOSTING RATES AT TIMES. IT COULD BE A PROLONGED PERIOD
OF LIGHT SNOW FOR MANY AREAS BUT AT THIS TIME UNSURE OF IMPACTS
SUITED FOR WINTER HEADLINES. LARGE SCALE ASCENT...MOISTURE AND
INSTABILITY ALL GET A STRONG BOOST BY FRIDAY AS AGAIN WEST COAST
ENERGY MERGES OVER THE ROCKIES. THIS STORM HAS THE POTENTIAL TO
BRING ANOTHER ROUND OF SIGNIFICANT SNOW THE REGION THROUGH GOING
INTO THE WEEKEND. THIS STORM IS MUCH COLDER AND NOT AS MOIST BUT
TEMPERATURES SUGGEST THE LOWER DENSITY SNOW WILL BE EASIER TO PILE
UP. THERE IS ALSO A DEEPER FOCUS FOR ASCENT WITH A COLD FRONT
PUSHING THROUGH THE CWA FRIDAY EVENING...STAY TUNED.
