Area Forecast Discussion
National Weather Service Denver/Boulder CO
430 PM MST Fri Dec 16 2016

.SHORT TERM...(This evening through Saturday)
Issued at 425 PM MST Fri Dec 16 2016

A complex weather system will produce a variety of weather over
the next 12-24 hours. A warm and increasingly moist southwest flow
aloft in advance of an upper trough and low intensifying over Utah
will track east across Colorado overnight. This system has been
generating quite a bit of upright convection complete with
lightning and periods of intense precip across nrn utah sern
Idaho this afternoon. Over Colorado the moist and unstable flow
has been producing bands of moderate precip over the western
valleys and the northern/central mountain areas. West/southwest
winds along the Continental Divide have also been gusty this
afternoon with gusts in the 30-40 mph range. On the plains...an
arctic airmass has covered the area with temperatures in the teens
and 20s...but no precip yet. That will come later when the
forcing upstream over Utah passes over the region overnight. In
the high country... should see a rather rapid increase in snowfall
coverage and intensity with increasing QG ascent and mid-level
instability. This evening could see snowfall rates of 1-2 inches
per hour in the high country and as the main storm front and
associated convection moves through the area...could see local
snowfall rates approaching 3 inches per hour. Rates of this
magnitude are likely to last for not more than a few hours. Right
now this enhanced high country snowfall will occur sometime
between 10 pm-3 am MST. Travel in the high country will likely be
most impacted during this period.

At lower elevations...light snowfall overnight may appear in bands
and under the stronger south-to-northeast oriented bands...could
see snowfall rates of 1-2 inches hour. Difficult to pin down
where these bands will set up. Some of the models show a thick
band of moderate snowfall setting up just south of the Denver and
extending northeast across ern Adams...ern Arapahoe...Elbert...srn
Washington and nrn Lincoln Counties after midnight. A shift
either north or south could mean a big difference in accumulations
across a n area. Probably won't know where these bands set up
until just before they begin showing up on radar. As for overnight
temperatures...one word - cold! Sub-zero temperatures will
prevail even with overcast skies. In addition...gusty northerly
winds developing on the plains after midnight could produce
pockets of blowing snow and dangerously cold wind chills in the
15 to 25 below zero range. For that reason...a Wind Chill Advisory
has been issued for eastern portions of the CWA. Advisory runs
from midnight to noon Saturday. Not to forget...a Winter Storm
Warning remains in effect for the mtn zones 31...33 and 34.
Warning for heavy snow and blowing snow runs until noon mst
tomorrow.

On Saturday...the upper trough passes over the Front Range area
early in the morning providing additional lift for light snowfall
during the morning hours. By afternoon...drying aloft and a shift
to northwest flow aloft in the wake of the trough should cause a
fairly rapid reduction in snowfall from northwest to southeast
across the CWA. Should see very little warming tomorrow with near
zero and single digit temperatures the rule.

.LONG TERM...(Saturday night through Friday)
Issued at 425 PM MST Fri Dec 16 2016

The upcoming week will feature a return to drier conditions along
with a warming trend through the middle of next week. Behind
Saturday's storm system, the flow aloft will become a drier,
northwest flow. There will be occasional gusty winds in the
mountains and exposed east slopes on Sunday and Monday.
Temperatures will rise to near and slightly above seasonal
normals on the plains for Tuesday and beyond.

The next weak system in the flow aloft will move across the
mountains late Tuesday and Wednesday. Moisture looks limited so
just chance pops for now and continued dry over the plains. The
next major influx of moisture will move into the mountains late
Thursday and Friday.

&&

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 425 PM MST Fri Dec 16 2016

IFR conditions late this afternoon at denver area airport still
expected to deteriorate to ILS conditions with prevailing ceilings
below 1000 ft and visibilities less than a half mile at times in
light to moderate snowfall overnight. Snowfall is currently
expected to develop in the Denver area between 7 and 9 PM MST this
evening...with a peak in snowfall intensity sometime between 11
pm and 4 am MST as the upper trough/weather disturbance now over
Utah passes over the I-25 corridor. Snowfall rates under 1 inch
will be common overnight...it's possible we could see rates
approaching 1.5 inches per hour under the heavier bands of
snowfall extending northeast of the Front Range. Snowfall should
steadily diminish during the morning hours with little additional
accumulation expected at Denver area airports after 9 am MST.
Airports should see VFR conditions and drier northerly winds by
around 18z/Saturday.

&&

.BOU WATCHES/WARNINGS/ADVISORIES...
Winter Storm Warning until 11 AM MST Saturday for COZ031-033-034.

Wind Chill Advisory from midnight tonight to noon MST Saturday
for COZ042-044>046-048>051.

...WINTRY WEATHER FOR THE OUTLOOK AREA THROUGH SATURDAY...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHEAST AND NORTH CENTRAL
COLORADO.

.DAY ONE...TODAY AND TONIGHT

SNOWFALL WILL INCREASE IN THE HIGH COUNTRY THROUGH THE DAY AND
BECOME HEAVY AT TIMES THIS AFTERNOON AND OVERNIGHT. ACCUMULATIONS
BY LATE TONIGHT WILL RANGE FROM 6 TO 12 INCHES FOR MOST OF THE
MOUNTAIN AREAS...WITH UP TO TWO FEET UP ALONG THE CONTINENTAL
DIVIDE AND ON UPPER WEST FACING MOUNTAIN SLOPES. WINDS OF 20 TO
30 MPH WITH HIGHER GUSTS TO AROUND 55 MPH WILL PRODUCE BLOWING
AND DRIFTING SNOW IN THE HIGH COUNTRY. GUSTY NORTHERLY WINDS ON
THE PLAINS MAY ALSO PRODUCE AREAS OF BLOWING SNOW AS WELL AS
DANGEROUSLY COLD WIND CHILLS. THE MOUNTAIN VALLEYS AND FOOTHILLS
WILL SEE LIGHTER ACCUMULATIONS...WITH TOTALS ANYWHERE FROM 3 TO 8
INCHES BY SATURDAY MORNING. THE PLAINS WILL ALSO SEE LIGHT
ACCUMULATIONS WITH AMOUNTS RANGING FROM AN INCH OR TWO IN THE FAR
NORTHEAST CORNER TO UPWARDS OF 3 TO 6 INCHES NEAR THE FOOTHILLS
AND ON THE PALMER DIVIDE.

AN ARCTIC COLD FRONT WILL ALSO BRING MUCH COLDER TEMPERATURES TO
THE PLAINS TODAY WITH TEMPERATURES FALLING THROUGH THE DAY.
OVERNIGHT TEMPERATURES WILL BOTTOM OUT BELOW ZERO IN MOST AREAS
WITH WIND CHILLS WELL BELOW ZERO IN THE MOUNTAINS AND NORTHEAST
PLAINS.

THE WINTRY WEATHER WILL HAMPER TRAVEL AS MANY ROADS WILL BECOME
SNOW COVERED AND BLOWING SNOW MAY SIGNIFICANTLY REDUCE VISIBILITIES
PARTICULARLY OVER THE MOUNTAIN PASSES AND UP AROUND THE EISENHOWER
TUNNEL.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

LIGHT SNOW WILL CONTINUE EARLY SATURDAY MORNING BUT IT WILL DECREASE
FROM NORTH TO SOUTH ACROSS THE FORECAST AREA BY LATE MORNING.
THERE WILL BE A FEW LINGERING SNOW SHOWERS OVER THE HIGH
MOUNTAINS DURING THE AFTERNOON. ADDITIONAL ACCUMULATIONS WILL BE
UP TO 2 MORE INCHES OVER THE PLAINS AND UP TO 4 MORE INCHES OVER
THE MOUNTAINS. THE GREATER DENVER AREA COULD SEE UP TO ONE MORE
INCH.

DRY WEATHER IS EXPECTED THROUGH TUESDAY IN THE MOUNTAINS...AND
THROUGH THURSDAY OVER THE PLAINS. THERE WILL BE A CHANCE OF LIGHT
SNOW IN THE MOUNTAINS TUESDAY NIGHT AND WEDNESDAY.

AS FOR TEMPERATURES...AN ARCTIC AIRMASS WILL BE IN PLACE SATURDAY
AND SUNDAY. IT WILL MODERATE BY MONDAY AND TEMPERATURES WILL BE
NEAR OR A BIT ABOVE SEASONAL NORMALS MUCH OF NEXT WEEK.
