.SHORT TERM...(THIS EVENING THROUGH FRIDAY NIGHT)

THIS MUCH ADVERTISED STORM SYSTEM HAD FINALLY PUSHED INTO THE
PACIFIC NORTHWEST THIS AFTERNOON. THE SURFACE LOW AHEAD OF THE
UPPER SYSTEM IS DEEPENING OVER CENTRAL WYOMING WITH THE ASSOCIATED
COLD FRONT IS SLOWLY PUSHING EAST ACROSS SOUTHWEST WYOMING AND
NORTHEAST UTAH AND APPROACHING THE UINTA BASIN AT 3 PM. MUCH OF
THE FOCUS FOR HEAVIER PRECIPITATION WILL BE FOCUSED NEAR THIS
FRONT AS WE AWAIT FOR THE STRONGER DYNAMICS ASSOCIATED WITH THE
MAIN SYSTEM. TONIGHT THIS INCLUDES THE NORTH UTAH AND COLORADO
MOUNTAINS AND AREAS OF THE NORTHWEST PLATEAU. TEMPERATURES
WILL QUICKLY FALL BEHIND THE FRONT AND FORCING FROM THIS LOW
LEVEL FEATURE IS EXPECTED TO HELP CHANGE RAIN TO SNOW DOWN TO NEAR
THE 6000 FT LEVEL. SNOW RATES SHOULD BE HEAVY ENOUGH TO IMPACT
AREA ROADWAYS IN OUR NORTHERN CWA THOUGH THE BEST SNOW AMOUNTS
LIKELY WILL REMAIN ON VEGETATION IN THE LOWER ELEVATIONS. THE
FLOW ALOFT WILL BE BACKING TO THE SOUTH DURING THE EARLY MORNING
HOURS AND THIS SHOULD SLOW THE PROGRESSION OF THE FRONT AND IT
APPEARS IT WILL HANG SOMEWHERE NEAR A VAIL PASS...BISECT THE
UNCOMPAHGRE PLATEAU...TO THE ABAJO MOUNTAINS IN SOUTHEAST UTAH.
MID LEVEL DYNAMICS AND FLOW OVER THE SURFACE STALLED FRONT WILL
FORCE AN AREA OF HEAVIER PRECIPITATION FROM SOUTHEAST UTAH TO THE
CENTRAL COLORADO MOUNTAINS. SOUTHERLY FLOW INTO THE SAN JUANS WILL
PRODUCE SOME SNOW OVER THE HIGH PASSES BUT WITHOUT THE COLD LOW
LEVEL AIR SNOW LEVELS LOOK TO STAY AOA 9000 FEET FOR MUCH OF THE
DAY. THAT SAID CONVECTION AND HEAVIER SHOWERS WILL DROP THAT LOWER
AT TIMES IN THE AFTERNOON. THE STORM WILL BE SETTLING SOUTHEAST OF
THE 4 CORNERS BY EARLY EVENING WHERE IT WILL STAY PARKED INTO
SUNDAY. THE COLDER AIR ARRIVING ALOFT WILL HELP FORCE THE COLD
FRONT THROUGH THE SOUTHERN ZONES OF OUR CWA AND SET THE STAGE FOR
HEAVIER PRECIPITATION IN THE SOUTH TO START THE WEEKEND. SNOW
LEVELS WILL CRASH INTO THE UPPER PORTIONS OF THE SOUTHERN VALLEYS.
CONFIDENCE STILL NOT HIGH ON PRECIPITATION TYPE ALONG AND SOUTH OF
THE HIGHWAY 160 CORRIDOR ATTM. ENSEMBLE GUIDANCE AND BUFKIT DATA
SUGGEST TEMPERATURES AND WET BULBS KEEPING PTYPE AT RAIN OR VERY
WET SNOW THAT MAY BE HARD TO ACCUMULATE ON ROADWAYS. WILL CONTINUE
TO EVALUATE HOW THE COLD AIR FILTERS IN DOWN SOUTH. STRONG
COOLDOWN WITH THIS FRONT AND TEMPERATURES FRIDAY AFTERNOON COULD
END UP SOME 15 TO 20 DEGREES COOLER THAN THE PAST FEW DAYS.
.LONG TERM...(SATURDAY THROUGH THURSDAY)
ISSUED AT 355 PM MDT THU APR 14 2016
WRAP AROUND MOISTURE IS STILL PROGGED TO TAKE AIM AT THE SOUTHERN
MOUNTAINS SATURDAY AS THIS SYSTEM BECOMES MORE VERTICALLY STACKED.
THIS WILL BE THE MAIN TIME OF HEAVY PRECIPITATION IN THE SOUTHERN
PART OF THE CWA AND WHEN SNOW RATES ARE LIKELY TO CAUSE PROBLEMS
ALONG MOUNTAIN ROADWAYS. IF THE DOMINANT PTYPE BECOMES SNOW IN THE
SOUTHERN VALLEYS IT COULD GET MESSY. ON THE MEAN TIME UP NORTH
WINDS WILL BEGIN TO INCREASE AS THE GRADIENT BEGINS TO TIGHTEN AND
THE NORTHERLY FLOW COULD LEAD TO SOME WIND ISSUES FROM NORTHWEST
COLORADO INTO EAST CENTRAL UTAH. AT THE MOMENT PRECIPITATION IS
NOT FORECAST TO BE HEAVY UP NORTH BUT WILL BE ANOTHER DECISION
ALONG THE WAY FOR ADDITIONAL HEADLINES AS COLD AIR WILL BE IN
PLACE UP NORTH AND SNOW IS THE LIKELY FORM OF PRECIPITATION. THE
LOW WILL BE OPENING UP LATE SATURDAY INTO SUNDAY MORNING AND THE
LOW WILL BE BEGIN TO WOBBLE AROUND WITH MANY DIFFERENT SOLUTIONS
LATE THIS AFTERNOON. FEEL THE HEAVIER WRAP AROUND MOISTURE WILL BE
FORCED NORTHWARD AND SPREADING ANOTHER SHOT OF HEAVIER SNOW RATES
ACROSS THE CENTRAL THEN NORTHERN MOUNTAINS THROUGH SUNDAY
AFTERNOON...WITH CONVECTIVE ACTIVITY FILLING IN ACROSS THE SOUTH
IN THE AFTERNOON. THEREFORE SNOW HEADLINES CONTINUE INTO SUNDAY
EVENING ATTM THROUGH SOME BREAKS ARE LIKELY BEFORE THEN. MODELS
HAVE SLOWED THE EJECTION OF THIS SYSTEM TO THE EAST AND UNSETTLED
WEATHER IS LIKELY TO STICK AROUND WESTERN COLORADO INTO MONDAY
EVENING AS THE BACK EDGE ENERGY ROTATES THROUGH. BEYOND THIS
WARMING AND DRYING SHOULD TAKE HOLD BY MIDWEEK.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z FRIDAY EVENING)
ISSUED AT 451 PM MDT THU APR 14 2016
A COLD FRONT WILL MOVE ACROSS NE UT AND INTO NW CO THIS EVENING
AND CONTINUE MOVING SOUTH AND EAST OVERNIGHT. THE FRONT SHOULD
STALL OVER THE SAN JUAN MTS FRI. EXPECT A LINE OF SHOWERS AND
ISOLD TO SCT THUNDERSTORMS ALONG THE FRONT.
EXPECT LOCAL MT TOP OBSCURATIONS THROUGH THE NEXT 24 HRS AND ILS
BREAKPOINTS WILL BE MET UNDER STRONGER SHOWERS AT MOST AIRPORTS.
