NATIONAL WEATHER SERVICE DENVER CO
400 AM MST FRI NOV 14 2008

.SHORT TERM...WATCHING A FEW BANDS OF LIGHT SNOW ON RADAR SWEEPING
S-SEWRD ACROSS NERN COLORADO AT THIS HOUR. OBSERVING SITES SUCH AS
FORT COLLINS...GREELEY AND AKRON REPORTED CIGS AS LOW AS 600 TO 800
FT AGL AND VSBYS AS LOW AS 1-2 MILES IN LIGHT SNOW/FOG AS THESE
SHOWER BANDS PASSED BY. SOUTHERN EDGE OF THIS PRECIP SHIELD NOW
REACHING THE DENVER METRO AREA...BUT THE HEAVIER SHOWER BAND STILL
UPSTREAM OVER CNTRL WELD AND ERN LARIMER COUNTIES. AT ITS PRESENT
SPEED SHOULD SEE THIS SNOW BAND MOVE THRU THE METRO AREA BETWEEN
11Z-13Z THIS MORNING. NOT LOOKING FOR MUCH IF ANY ACCUMULATION WITH
WARM GROUND TEMPS AND WITH THE SHALLOW DEPTH OF THE MOIST UPSLOPE
SURGE. SHOULD SEE MOST THE PCPN ON THE PLAINS CLEARING THE AREA BY
MID-MORNING AS BNDRY WINDS PICK UP IN SPEED AS THEY TURN TO A NWLY
COMPONENT. ACCORDING TO THE RUC AND NAM...SHOULD SEE CLEARING SKIES
BY MIDDAY IF NOT SHORTLY AFTER THAT WITH STG SUBSIDENCE MOVING OVER
THE AREA. AT THE SAME TIME SHOULD SEE A STEADY INCREASE IN WIND
SPEEDS WITH GUSTS APPROACHING 50 MPH ACROSS THE FAR NERN COUNTIES
AROUND MID-AFTERNOON. SPEEDS EXPECTED TO REMAIN BELOW HIGH WIND
CRITERIA...BUT WOULDNT RULE OUT A FEW REPORTS OF GUSTS TO +60 MPH
GUSTS NEAR THE NEBRASKA BORDER. OVERNIGHT SHOULD SEE A DRAMATIC DROP
OFF ON THE WINDS AND WITH CLEAR SKIES WILL SEE MINIMUM TEMPS BY DAWN
IN THE TEENS AND 20S. AS FOR TEMPS TODAY...SHOULD SEE TEMPS AS MUCH
AS 25 TO 30 DEGS BELOW THOSE OBSERVED YESTERDAY.

IN THE HIGH COUNTRY...ALSO SEEING AN INCREASE IN SNOWFALL IN THE
PAST COUPLE OF HOURS WITH THIS LAST WAVE OF MOISTURE MOVING THRU.
LOOKING FOR ANOTHER 2-4 INCHES OF SNOW BY LATE MORNING...MAINLY ON
NORTHWEST FACING MTN LOPES. OTHERWISE A POWERFUL N-NWLY ORIENTED
POLAR JET OVER THE CONTINENTAL DIVIDE AT THIS HOUR PROBABLY
RESPONSIBLE FOR THE IMPRESSIVE WIND GUSTS OBSERVED AT A NUMBER OF
HIGH MTN PEAK AND RIDGE TOP AUTOMATED WEATHER SENSORS. COUPLE HOURS
AGO...SAW A REPORT OF 113 MPH ATOP BERTHOUD PEAK JUST OUTSIDE OF
WINTER PARK. GRANTED THE REPORTING SITE IS UP NEAR 13000 FEET
MSL...POSSIBLY JUST BELOW THE JET CORE AT THE TIME. ANYHOW...LATEST
CDOT ROAD REPORTS STILL INDICATING SNOW AND BLOWING SNOW...AS WELL
AS SNOW PACKED AND ICY ROAD CONDITIONS ON MANY OF THE HIGH MTN
PASSES. SHOULD SEE A GRADUAL END TO SNOWFALL FROM NORTH TO SOUTH AS
THE MORNING PROGRESSES BUT STRONG N-NWLY WINDS SHOULD CONTINUE.
THEREFORE WILL CONTINUE THE WINTER WEATHER ADVISORY FOR MTN ZONES
31.33 AND 34 UNTIL 18Z/TODAY. HOWEVER THE ADVSY IN ZONE 31 MAY BE
DROPPED BEFORE THEN.

.LONG TERM...RIDGING ALOFT WILL BUILD ACROSS THE WEST COAST OVER THE
WEEKEND WITH A GRADUAL WEAKENING OF THE NORTHWEST FLOW PATTERN
ACROSS CO. WARMING TREND AND DRY CONDITIONS WILL PREVAIL THROUGH THE
WEEKEND. A WEAK FRONT WILL BACK DOOR INTO NERN CO SUN NITE/EARLY
MONDAY WITH SOME COOLING EXPECTED FOR MONDAY. GIVEN CURRENT GFS/NAM
TEMP PROFILES...WILL NEED TO LOWER TEMPS A BIT MORE FOR MONDAY.
COULD BE A STRATUS DECK ASSOCIATED WITH IT BUT UNCLEAR HOW EXTENSIVE
OR HOW FAR WESTWARD THE MSTR WILL GET. FOR NOW...WILL INCREASE THE
CLOUD COVER BUT NOT EXPECTING ANY PRECIP. THE RIDGE ALOFT WILL BUILD
EASTWARD AGAIN THRU TUESDAY WITH WARMER TEMPS AGAIN FOR TUESDAY WITH
READINGS AROUND 70 DEGREES ACROSS LOWER ELEVATIONS. GFS STILL
SHOWING A WEAK WAVE AROUND THE WED TIME FRAME SO COOLER TEMPS AGAIN.
WILL LEAVE DRY FOR NOW AS UNCLEAR HOW MUCH MOISTURE THIS WAVE WILL
ACTUALLY HAVE.

&&

.AVIATION...A COUPLE BANDS OF LIGHT SNOWFALL MOVING SOUTHWARD
THROUGH THE I-25 URBAN CORRIDOR WILL PASS OVER THE DENVER METRO AREA
BETWEEN 11Z AND 13Z. MVFR CIGS AND VSBYS DUE TO LIGHT SNOW AND FOG
WILL PREVAIL WITH LOCAL IFR CIGS AND VSBYS WITH THE PASSAGE OF THE
HEAVIEST SNOW BAND AROUND 12Z. AFTER 13Z...SHOULD SEE STEADY
IMPROVEMENT AS DRIER AIR MOVES IN ON GUSTY NORTH-NORTHWEST WINDS.
VFR CONDITIONS EXPECTED BY 15Z AT DENVER AREA AIRPORTS. CLEARING
