400 AM MST TUE FEB 18 2014

.SHORT TERM...MODEL DEPICTIONS SHOW THAT THE LEADING EDGE OF THE
PACIFIC JET STREAM IS JUST MOVING OVER NORTHERN COLORADO IN THE
PAST COUPLE HOURS. THE PLATTEVILLE PROFILER SHOWS WESTERLY WINDS
OF 55 KNOTS DOWN TO 650 MB...NEAR RIDGETOP LEVEL OVER THE
MOUNTAINS. FAVORABLE VERTICAL SHEAR PROFILES SHOULD REMAIN IN
PLACE FOR A FEW MORE HOURS...JUSTIFYING THE HIGH WIND WARNING OVER
THE MOUNTAINS AND FOOTHILLS. OVER THE PAST HOUR AND A HALF THE
DOPPLER RADAR HAS BEEN SHOWING THE MOUNTAIN WAVE SIGNATURE
DESCENDING OVER THE FRONT RANGE FOOTHILLS. MESONET OBSERVATIONS
FROM THE FOOTHILLS WEST OF BOULDER AND GOLDEN ARE SHOWING WIND
GUSTS TO 55-75 MPH WHILE 35-45 MPH GUSTS ARE BEING RECORDED FROM
EASTERN BOULDER EASTWARD TO ERIE. WINDY CONDITIONS SHOULD CONTINUE
THROUGH ABOUT MID-MORNING BEFORE TOO MUCH VERTICAL SHEAR DEVELOPS
AND THE MOUNTAIN WAVE BEGINS TO BREAK DOWN. THE RUC AND RAP MODELS
SHOWBREEZY CONDITIONS SPREADING ACROSS THE PLAINS THROUGH EARLY
AFTERNOON DUE TO STRONG VERICAL MIXING OF WINDS ALOFT DOWN TO THE
SURFACE. SPEEDS ON THE PLAINS ARE NOT EXPECTED TO REACH HIGH WIND
CRITERIA...SO NO HIGHLIGHTS ARE ANTICIPATED OUT THERE.

THE WINDY CONDITIONS THIS MORNING HAVE KEPT TEMPERATURES MILD
ACROSS THE COUNTY WARNING AREA...AND SHOULD ALLOW TEMPERATURES TO
WARM TO THEIR MAX READINGS BY ABOUT THE NOON HOUR. OTHER THAN THE
WIND AND WARM TEMPERATURES...INCREASING HIGH CLOUDS BY AFTERNOON WILL
BE THE ONLY OTHER SENSIBLE WEATHER ELEMENT TO WORRY ABOUT. WINDS
WILL CONTINUE DECREASING TONIGHT AS PRESSURE GRADIENTS RELAX AND
THE UPPER JET MOVES NORTH OF THE STATE.

.LONG TERM...AN UPPER LEVEL TROUGH WILL MOVE ACROSS THE AREA WED AFTN
INTO WED NIGHT AND THEN BE EAST OF THE AREA BY THU MORNING.
MOISTURE WILL INCREASE IN THE MTNS AS THE SYSTEM APPROACHES WITH
THE FLOW SWITCHING FM SWLY TO NWLY BY EARLY WED EVENING AS THE
TROUGH MOVES ACROSS. WITH DECENT LAPSES RATE AND MDT QG ASCENT IN
THE MID LVLS THERE WILL LIKELY BE A PERIOD OF HEAVIER SNOW IN THE
00Z-06Z TIMEFRAME. AT THIS TIME IT LOOKS LIKE AN ADVISORY TYPE
EVENT IN MOST PLACES WITH GUSTY WINDS AS WELL. AT LOWER ELEVATIONS
SFC LOW PRES WILL INTENSIFY OVER ERN COLORADO DURING THE DAY AND
THEN MOVE EAST AS A CDFNT MOVES INTO NERN CO WED EVENING. AHEAD OF
THE FNT WILL SEE ANOTHER MILD DAY WITH READINGS IN THE 55 TO 60
DEGREE RANGE. AS THE CDFNT MOVES ACROSS WED EVENING WILL SEE A
BETTER CHC OF PCPN OVER NERN CO AS THE MAIN UPPER LEVEL TROUGH
MOVES ACROSS. SOUNDINGS SHOW RAIN WILL CHANGE TO SNOW AFTER 03Z SO
A FEW PLACES COULD PICK UP A QUICK INCH OR SO WITH PCPN DECREASING
AFTER 06Z.

ON THU DRIER AIR WILL SPREAD ACROSS THE AREA HOWEVER THERE WILL
STILL BE SOME LINGERING SHALLOW MOISTURE IN THE MTNS WHICH MAY LEAD
TO SOME OROGRAPHIC DRIVEN LIGHT SNOW.  OVER NERN CO IT WILL BE DRY
HOWEVER IT WILL BE WINDY AS BNDRY LYR WINDS WILL BE IN THE 35-40 KT
RANGE.  THUS AS MIXING OCCURS WILL PROBABLY SEE SOME GUSTS UP TO 50
MPH OVER THE PLAINS.  AS FOR HIGHS WILL KEEP HIGHS MOSTLY IN THE
UPPER 30S TO LOWER 40S AS STG CAA WILL OCCUR.

FOR THU NIGHT THROUGH FRI NIGHT STG NWLY FLOW ALOFT WILL BE OVER THE
AREA AS A FEW DISTURBANCES MOVE ACROSS.  MOISTURE WILL INCREASE IN
THE MTNS WITH FAVORABLE OROGRAPHICS AND DECENT LAPSE RATES BY FRI
ALONG WITH SOME QG ASCENT.  THUS SHOULD SEE PERIODS OF SNOW IN THE
MTNS.  AT LOWER ELEVATIONS THE THREAT FOR HIGH WINDS WILL INCREASE
IN AND NR THE FOOTHILLS THU NIGHT INTO FRI MORNING AS CROSS MTN FLOW
INCREASES TO 65-70 KT.  OTHERWISE FOR FRI THE LOW LVL FLOW WILL BE
NWLY SO DO NOT EXPECT ANY PCPN OVER THE PLAINS.  AS FOR HIGHS WILL
KEEP READINGS IN THE LOWER TO MID 40S OVER NERN CO.

BY THE WEEKEND THE FLOW ALOFT WILL REMAIN MAINLY NWLY.  THE ECMWF
SHOWS MORE MOISTURE THAN THE GFS FOR SAT WHICH ALLOWS FOR A BETTER
CHC OF SNOW IN THE MTNS.  FURTHERMORE THE ECWMF SHOWS A CDFNT MOVING
INTO NERN CO ON SAT WHILE THE GFS KEEPS IT FURTHER NORTH OVER SERN
WY AND THE NE PNHDL.  AS A RESULT THE ECWMF SHOWS SOME UPSLOPE FLOW
DEVELOPING BY AFTN OVER NERN CO WITH A CHC OF PCPN ESPECIALLY SAT
NIGHT WHILE THE GFS SHOWS NO PCPN DUE TO HAVING THE FNT AND BETTER
MOISTURE FURTHER NORTH.  FOR NOW WILL MENTION AT LEAST A SLIGHT CHC
OF PCPN OVER NERN CO FOR SAT NIGHT.  FOR SUN BOTH THE ECMWF AND GFS
SHOW LIMITED MOISTURE IN THE MTNS AND OVER NERN CO THUS WILL ONLY
MENTION LOW POPS IN THE MTNS WITH DRY CONDITIONS OVER THE PLAINS.
LATEST 850-700 MB TEMPS WOULD KEEP READINGS MAINLY IN THE LOWER
TO MID 40S OVER NERN CO.

FOR EARLY NEXT WEEK THE ENDLESS PATTERN OF NWLY FLOW WILL CONTINUE.
THE ECMWF SHOWS ANOTHER CDFNT MOVING INTO NERN CO ON MON WHILE THE
GFS KEEPS IT FURTHER NORTH.  FOR NOW WILL KEEP HIGHS OVER NERN CO IN
THE MID 30S TO LOWER 40S WITH THE COLDER READINGS ALONG THE WY-NE
BORDER.  NEITHER MODEL SHOWS A LOT OF MOISTURE SO WILL JUST HAVE LOW
POPS IN THE MTNS AND ACROSS THE PLAINS.

&&

.AVIATION...WITH ALL OF THE WESTERLY FLOW COMING OVER THE
MOUNTAINS...ONE WOULD EXPECT WESTERLY WINDS AT THE AIRPORTS... AND
AT TIMES WE HAVE SEEN THAT. AT OTHER TIMES...SOUTHERLY DRAINAGE
WINDS HAVE DEVELOPED AT KDEN AND EVEN A BRIEF EASTERLY WIND HAS
OCCURRED AT KBJC. AFTER THE SUN COMES UP...WINDS SHOULD BECOME ALL
WEST AS DAYTIME HEATING MIXES LOW LEVEL WINDS DOWN TO THE SURFACE.
THE STRONGEST WINDS SHOULD BE OBSERVED THROUGH ABOUT 17Z WITH A
GRADUAL DECREASE THROUGH THE AFTERNOON. TYPICAL DRAINAGE WINDS ARE
EXPECTED TONIGHT. CEILINGS AND VISIBILITIES SHOULD BE UNLIMITED
ALL DAY.
