Area Forecast Discussion
National Weather Service Pueblo CO
359 AM MST Tue Jan 23 2018

.SHORT TERM...(Today and tonight)
Issued at 359 AM MST Tue Jan 23 2018

Currently...Latest satellite imagery shows mt wave clouds
dissipating and eroding to the north, under northwest flow aloft.
Thin cirrus was filtering in across the northwest quad of the state.

Today and tonight...Models indicate that northwest flow aloft will
relax and transition to a more westerly flow over the next 24 hours,
as a ridge of high pressure gradually slides east and approaches
Colorado. Expect generally lighter diurnal winds with dry conditions
and slightly warmer temps. Highs are forecast to be in the 30s to
near 40F for the high valleys, and in the 40s across the plains.

.LONG TERM...(Wednesday through Monday)
Issued at 359 AM MST Tue Jan 23 2018

Wednesday and Thursday...A ridge of high pressure will slide across
the Great Basin and Four Corners through Thursday ahead of the next
weather system, shifting the flow aloft to a more southwest
direction by Thu. Dry conditions and warming temps are expected.
Increasing winds on Thu may create some spotty near-critical fire
weather conditions along the I-25 corridor and eastern plains Thu
aftn. Look for high temps in the 40s for the high valleys and 50s
for the plains on Wed, then 40s to lower 0s for the high valleys and
60s for the plains on Thu.

Friday...A broad upper low pressure trough will cross the Rockies
late Thu night through Fri, bringing snow to the higher terrain.
Snow will begin along the Continental Divide and especially the
central mts soon after midnight Thu night, then continue through the
day Fri before tapering off early Sat morning. A dry cold front will
push south across the eastern plains Fri aftn, bringing about 5 to
10 degrees of cooling to all areas.

Saturday through Monday...Save for a few lingering snow showers over
the central mts under northwest flow aloft early Sat morning, dry
and warming conditions are expected. Look for highs in the 40s for
most locations on Sat, 40s for the high valleys and 50s for the
plains on Sun, then mid 40s to mid 50s for the high valleys and mid
50s to lower 60s for the plains on Mon. Moore
