The core of the strongest winds aloft are shifting east of the
divide this morning and most mountain areas have dropped well
below advisory criteria. A few localized gusts over 50 mph will
still be possible in the high country through the afternoon but
overall conditions will be improving. Light showers along the
Wyoming border will be dropping into the northern Colorado
mountains through the day as a cold front progresses through the
region. Still expecting any accumulations to be near and above
timberline though snow should be falling as low as 8500 feet.
Temperatures cooler across the state today but especially the
north where high temperatures have been met for the day and will
continue to fall or stay steady.
.SHORT TERM...(Today through Tuesday)

The current IR satellite image is showing mostly clear skies
around the area this morning with some high clouds in place over
Northeastern Utah and Northwestern Colorado. Breezy conditions
are lingering around the area this morning as a surface boundary
continues to sag south into Eastern Utah and Western Colorado.
This surface boundary will cool temperatures down around the area
today. On average most locations will see afternoon high
temperatures ranging between 5 to 10 degrees cooler than those
observed on Sunday. The coolest temperatures will be north of
I-70. Along with the cooler temperatures showers will be a
possibility today for the northern portion of the CWA as the
surface boundary moves south.
.LONG TERM...(Tuesday through Sunday)

Another piece of the strong polar jet and upstream energy will
drop into the Pacific Northwest Monday evening and approaches our
region by mid to late afternoon. The trend of this passing system
continues to be a weakening one in the major models. This seems
mainly due to minimal moisture advection from the northwest.
Instability and general upward lift appears to be better focused
over our northern zones through Tuesday evening but again snow
amounts look on the light side. Significantly cooler air moves in
behind this wave and temperatures look to end up on the low side
of normal for at least Wednesday before we begin another dry and
warm stretch. The jet stream retreats well to the north to end the
week with a dominate ridge building in across the west.
Temperatures should return to above normal Friday and persist
through at least the weekend.
.AVIATION...(For the 12Z TAFS through 12Z Tuesday morning)
Issued at 515 AM MDT Mon Oct 17 2016
Another windy day with strong gusts is expected today as a
surface front pushes south into Utah and Colorado. Otherwise VFR
conditions are expected to prevail through the next 24 hours.
