419 am MST Tuesday Feb 9 2016

Short term...(today and tonight)
issued at 419 am MST Tuesday Feb 9 2016

Moderate...dry...and warmer northwest flow aloft will persist
across Colorado. This will bring sunny skies and above normal
temperatures to the forecast today. The warmest readings will be
along the Front Range where downslope warming will offset snow
cover. This is where we should add on about 10 degrees from highs
observed yesterday...while farther east about another 5 given the
deeper snow cover and less downslope contribution there. Breezy
conditions expected to continue across the higher peaks and down
the Front Range foothills and Park County with sufficient Cross
Mountain component...as well as the northeast plains where
gradient is stronger.

Tonight will feature quite mild readings along the Front Range
with continued downslope and warm advection. Inversions should be
able to set up farther east across the plains but some wind to
keep things more mixed on the ridges. Stronger inversion likely to
hold in Grand County valleys.

Long term...(wednesday through monday)
issued at 419 am MST Tuesday Feb 9 2016

Strong upper ridging is forecast over the western U.S. Through the
end of the week with dry and moderate northwesterly flow aloft
over Colorado. Dry and mostly sunny conditions will result with
temperatures peaking for the week on Wednesday afternoon. Lee
troughing across eastern colroado on Wednesday is going to be
replaced by a weak surface high pressure ridge
Thursday...accounting for the cooling in temperatures. Through the
rest of the week and into the weekend...the upper ridge will
weaken as a short wave trough comes out of the Pacific northwest
and brushes across northern Colorado. The bulk of energy with this
trough will affect Wyoming...but enough moisture...orographics and
instability will develop over the mountains for some light snow to
develop. Sunday morning through Monday morning will be the best
chance for light snow in the mountains. The plains will remain dry
through the forecast period with temperatures also warmer than
normal.

Wednesday night may see a period of gusty winds in the foothills
as the nose of a passing upper jet sets up a wind profile that is
favorable for the amplification of a mountain wave for 6 to 10
hours. Cross sections indicate that gusts of 40 to 60 miles per hour will be
possible in the normally windy locations. The winds should develop
early in the evening and then gradually dissipate after midnight.
The strength of the flow does not seem to be enough to warrant any
highlights at this time.

Aviation...(for the 12z tafs through 12z Wednesday morning)
issued at 419 am MST Tuesday Feb 9 2016

Nearly cloud free skies expected through tonight. Southerly surface
winds around 10 knots at kapa and kden expected to become variable
around 6 knots by 18z. May be some trend to north/northeast
thereafter but snow cover usually keeps winds light and variable
in these cases. Then winds go back to south/southwest at 8-12
knots toward 00z Wednesday and hold there overnight. Kbjc could
see a few westerly gusts to around 20 knots from time to time due
to weak mountain wave...but overall lighter winds should prevail
there as well.
