AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
313 PM MST TUE FEB 11 2014

.SHORT TERM...THE RAP...NAM AND GFS MODELS ALL INDICATE A SHORT
PERIOD OF SNOW IN THE NORTHERN MOUNTAINS THIS EVENING. RADAR DATA
FROM SALT LAKE CITY HAS SHOWN AN INCREASE IN ECHOES OVER THE PAST
HOUR OR TWO. A WEAK DISTURBANCE EMBEDDED IN THE NORTHWEST FLOW
ALOFT WILL APPARENTLY BE JUST ENOUGH TO GENERATE THE SNOW SHOWER
ACTIVITY. PREVIOUS FORECASTS HAVE MENTIONED UP TO A COUPLE INCHES
OF SNOW WITH THIS FEATURE...SO WILL NOT MAKE ANY CHANGES NOW.
BREEZY CONDITIONS OVER THE MOUNTAIN PEAKS AND FOOTHILL AREAS WILL
BE THE OTHER CONCERN WITH THE FORECAST. GUSTS OF 30 TO 40 MPH WILL
BE POSSIBLE OVER THE FOOTHILLS AND UP TO 55 MPH OVER PARTS OF THE
CONTINENTAL DIVIDE. NORTHWESTERLY JET LEVEL WINDS UP TO 120 KNOTS
WILL BE DRIVING THE WINDS OVER THE HIGH TERRAIN. MODEL CROSS
SECTIONS KEEP THE STRONGEST WINDS IN THE MOUNTAINS WITH ONLY A
BRIEF PERIOD WHERE THE MOUNTAIN WAVE COMES DOWN OVER THE
FOOTHILLS. ON THE PLAINS...SKIES WILL CLEAR OUT DURING THE
EVENING...ALLOWING TEMPERATURES TO DROP TO THE LOWER 20S. THE
AIRMASS HAS BEEN WARMING TODAY UNDER THE BRISK NORTHWEST FLOW
ALOFT...SO THE VERY COLD OVERNIGHT TEMPERATURES APPEAR TO BE A
THING OF THE PAST.

.LONG TERM...MODELS HAVE PRETTY STRONG NORTHWESTERLY FLOW ALOFT OVER
THE CWA WEDNESDAY NIGHT THROUGH FRIDAY NIGHT. THE JET MAXIMUM IS
PROGGED TO BE JUST TO OUR NORTH AND NORTHEAST THOSE FIVE PERIODS.
THE QG VERTICAL VELOCITY FIELDS HAVE VERY LITTLE UPWARD MOTION FOR
ANY OF THE FORECAST AREA WEDNESDAY NIGHT THROUGH FRIDAY NIGHT.
MOST OF THE TIME WEAK DOWNWARD ENERGY IS PROGGED. FOR MUCH OF THE
TIME THE BOUNDARY LAYER FLOW LOOKS TO BE DOMINATED BY DOWNSLOPING
WINDS. CONCERNING MOISTURE...MODELS SHOW FAIRLY DEEP MOISTURE OVER
THE MOUNTAINS WEDNESDAY NIGHT INTO FRIDAY...AT LEAST ON THE GFS.
THE ECMWF HAS CONSIDERABLE LESS DURING THAT TIME. THE NAM IS
SOMEWHERE IN THE MIDDLE. MOISTURE IS LIMITED OVER THE PLAINS
THROUGH FRIDAY NIGHT ON ALL THE MODELS. THE QPF FIELDS DO SHOW
LIMITED AMOUNTS OF MEASURABLE SNOWFALL OVER THE HIGH MOUNTAIN ZONES
ALL FIVE PERIOD. SO CONCERNING POPS AND THE MOUNTAINS HIGHLIGHTS
...MOISTURE IS GOOD ON THE GFS...POOR ON THE ECMWF. THERE IS WARM
AIR ADVECTION MUCH OF THE TIME AND TEMPERATURES ARE WARMER THAN
THEY SHOULD BE FOR OPTIMUM CRYSTAL GROWTH IN THE HIGH COUNTRY.
THERE IS PRETTY DECENT WIND SPEEDS AND DIRECTION TO AID IN
OROGRAPHIC ENHANCEMENT HOWEVER. THERE IS LITTLE HELP IN THE
SYNOPTIC SCALE ENERGY DEPARTMENT AND THE MOISTURE IS SOMEWHAT
QUESTIONABLE. QPF FIELDS POINT TO ADVISORY AMOUNTS...MAYBE.  WILL
LEAVE WATCH HIGHLIGHTS ALONE AT THIS TIME. WILL NEED ZERO POPS FOR
THE PLAINS. CONCERNING TEMPERATURES...THURSDAY'S HIGHS LOOK TO BE
3-5 C WARMER THAN WEDNESDAY'S. FRIDAY'S HIGHS ARE A TAD COOLER ON
FRIDAY. FOR THE LATER DAYS...SATURDAY THROUGH TUESDAY...FAIRLY
STRONG WESTERLY FLOW ALOFT IS PROGGED SATURDAY AND SUNDAY. ON
MONDAY AND TUESDAY...THE FLOW ALOFT DECREASES A BIT AND IS MOSTLY
WESTERLY. THERE IS SOME ALPINE MOISTURE SUNDAY AND SUNDAY NIGHT
...BUT NOTHING GREAT. THE REST OF THE DAYS ARE PRETTY DRY...
ESPECIALLY OVER THE PLAINS. TEMPERATURES LOOK TO STAY ABOVE
SEASONAL NORMALS ALL FOUR DAYS.

&&

.AVIATION...NO AVIATION IMPACTS EXPECTED THROUGH THE NEXT 24
HOURS. SOUTH AND SOUTHWESTERLY WINDS ARE EXPECTED TO CONTINUE
OVERNIGHT AND WEDNESDAY. CEILINGS WILL REMAIN HIGH AND
VISIBILITIES SHOULD REMAIN UNLIMITED.

&&

.BOU WATCHES/WARNINGS/ADVISORIES...
WINTER STORM WATCH FROM WEDNESDAY AFTERNOON THROUGH THURSDAY
EVENING FOR COZ031-033-034.
