.DISCUSSION /Through Thursday/...
Issued at 1144 PM MST Thu Feb 26 2026

Upper level ridging will continue through the start of the weekend
keeping highs in the mid 60s to near 70 degrees for Friday and
Saturday. Strong 700mb NW winds will remain near the area Friday
and Saturday leading to continued breezy winds in the mountains
and portions of the plains in the afternoons. For Friday, wind
gusts around 20 to 40 mph are expected across the plains, with the
highest winds coming off the Cheyenne ridge into our northern
counties. For Saturday, winds should be a bit weaker and more
confined to our northern most counties.

A strong surface high pressure will push a backdoor cold front into
the area Saturday into Sunday. On Sunday, behind the front, we`ll
see highs drop around 5 to 15 degrees compared to Saturday. The
easterly winds behind the front will also bring in higher
dewpoints and RH values, bringing an end to our string of near
critical to critical fire weather conditions. The increased
moisture and some weak upper lift could be enough to get some
showers going over the mountains Sunday into early Monday. There
is also a low chance (240-242>245-248-249.
