Area Forecast Discussion

250 AM MDT Tue Oct 24 2017

.SHORT TERM...(Today and tonight)
Issued at 220 AM MDT Tue Oct 24 2017

Northerly 140-150kt jet stream flow just east of the state this
morning will gradually translate eastward through the day. Some
of this high altitude momentum will likely mix down to the ground
across the nern corner of the CWA with dispersion of the morning
sfc based inversion late this morning. Should see n-nwly winds of
15-25 mph and peak gusts of 35-40 mph in the area roughly east of
a Cheyenne-to-Limon line. The gusty sfc winds should quickly
subside by early this evening with decoupling from the stronger
flow aloft. Otherwise, expect another dry day with just a few
stratus clouds along the foothills before sunrise, the product of
weak n-nely upslope flow overnight. Then just thin cirrus clouds
throughout the day. High temps today should be a few degs lower
than those yesterday with the last of the cold air advection
slowing the morning warmup. Tonight...the CWA will still be under
a moderate northwest flow aloft, but the typical drainage flow
should be light. Low temps tonight will be anywhere from 3-8 degs
warmer, with warmest readings along the base of the foothills the
result of a slightly enhanced downslope flow late tonight.


.LONG TERM...(Wednesday through Monday)
Issued at 220 AM MDT Tue Oct 24 2017

Wednesday will be dry and warm under a weak to moderate northwest
flow aloft. A cold front and upper level trof will move across
Colorado on Thursday with increasing north to northeast low level
flow. Best chance of measurable precip will be over the Front
Range foothills and higher east slopes during the day as snow
levels lower between 5000-6000 feet. Could see a few inches of
snow mainly in the higher foothills. Temperatures will be much
colder behind the front with readings on Thursday only in the 40s
along with windy conditions. Behind the trof, there will be a
continued moderate north to northwest flow aloft with breezy
conditions in the mountains through the weekend. There will also
be a warming trend as well. Very little change to upcoming
forecast.

.AVIATION...(For the 06Z TAFS through 06Z Tuesday night)
Issued at 220 AM MDT Tue Oct 24 2017

Winds will be generally light northerly before sunrise, then light
south-southwesterly from sunrise through around 17z, then back to
a north-northwest wind of 7-12 mph during the afternoon. After
sunset, should see our typical southerly drainage flow pattern set
up with speeds generally under 10 kts. Otherwise, dry today and
tonight with VFR conditions CIGs and VSBYs.
