Area Forecast Discussion
National Weather Service Pueblo CO
1208 PM MDT Wed Oct 18 2017

.SHORT TERM...(Today and tonight)
Issued at 338 AM MDT Wed Oct 18 2017

Current water vapor imagery is indicating moderate westerly flow
aloft across the region, with an embedded short wave translating
across the Northern Rockies at this time. Water vapor and IR
satellite imagery also indicating some embedded moisture within the
flow supporting mountain wave clouds across the Front Range at this

Today and tonight...No big changes to current forecast, as westerly
flow aloft across the region this morning, moderates and becomes
more southwest through tonight with the Northern Rockies wave
continuing to push east, as Eastern Pacific energy digging across
the Pacific Northwest Coast, starts to move into the Great Basin.
The passing Northern Rockies short wave sends a dry backdoor cold
front across Eastern Colorado later this morning, with generally
weak upslope flow developing across the plains through the
afternoon.  This, along with bouts of wave clouds across the area
through the afternoon, will lead to temperatures at to slightly
cooler than yesterday`s readings, though still above seasonal
levels, with highs in 70s to lower 80s across the lower elevations,
and mainly 50s and 60s across the higher terrain. Clearing skies
expected through the afternoon and evening, with lows generally in
the 30s to lower 40s.

.LONG TERM...(Thursday through Tuesday)
Issued at 338 AM MDT Wed Oct 18 2017

...Cooler weather for the weekend...

A couple of troughs will move across the region during this long
term period. The first trough is relatively weak and will move
across the region Thursday night/Friday morning and will bring
some light showers to the contdvd during the aforementioned time
period. A second stronger trough will move across the region
Saturday and will bring some light accumulating snows mainly to
the west slopes of the contdvd and possibly some showers
elsewhere. This second trough will also bring cooler air to the
region for the weekend.

Next week NW mid level flow will prevail with a couple of very weak
disturbances in the flow moving across the area. Expect mainly dry
weather with slightly above seasonable temperatures. /Hodanish
