.SHORT TERM /THROUGH THURSDAY/...
Issued at 1241 PM MDT Wed Aug 5 2026

Currently...Stratus has been fairly persistent across the far
eastern plains this morning, but cleared quickly along the I-25
Corridor. This has made for a very nice day for most areas, with
temps in the 70s and 80s as of 1230 PM. A few meager CU are
starting to develop over the ridges. As for the upper pattern,
an upper ridge remains over the Four Corners, while brisk W-NW
flow aloft persists across the northern Rockies.

Tonight and tomorrow...little change to the overall pattern. Showers
and thunderstorms will have the best chance along the southern
border late this afternoon and evening, with the main storm threat
expected to be gusty winds. Overnight lows are expected to cool into
the 40s to around 50F for the high valleys, and mid 50s to lower 60s
for the plains, and low clouds overnight are not forecast. Warmer
and more dry conditions are anticipated for tomorrow, and combined
with afternoon wind gusts, will produce critical fire weather
conditions along the Continental Divide through the afternoon. More
spotty fire danger will be possible as well across the San Luis
Valley and across Fremont County along the Arkansas River Valley,
but coverage does not look large enough to warrant a highlight for
those areas. Isolated showers and perhaps a thunderstorm or two will
be possible by mid-afternoon, mainly over the higher terrain and
along the southern border. Plan on highs in the 90s for most
locations, and nearing 100F for the eastern plains.

&&

.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
Issued at 1241 PM MDT Wed Aug 5 2026

Friday through Sunday...Upper ridge amplifies over the Four Corners
for Fri and Sat, and hot, dry conditions settle in. High temps each
day are expected to climb into the upper 80s to lower 90s for the
high valleys, and mid 90s to low 100s for the plains. By Sunday the
high pressure begins to flatten out, and the center of the ridge
shifts slightly to the west. Long range models are trending towards
a gradual increase in moisture for the higher terrain, but the
plains will remain dry. Given how hot it will be, spotty critical
fire weather conditions will definitely develop. Currently, wind
gusts seem to be the limiting factor and will restrict areal
coverage.

Monday through Wednesday...Monday still looks to be a very hot day
regionwide, with afternoon readings similar to the weekend. However,
around 5 degrees of cooling is then forecast for Tuesday and
Wednesday, likely in response to increasing precipitation chances
and cloud cover. Shower and thunderstorm chances jump up
considerably for the start of the next work week, mainly over the
higher tarrin but also spilling over across the I-25 Corridor.
Unfortunately, the far eastern plains stay dry at this time. If this
precip forecast persists, look for max temp forecasts to start
cooling even more over the next few days. Moore

direction, with a brief period of gusts to around 20 KT this
afternoon.
