Spot Forecast for Cottonwood Peak Fire...US Forest Service
National Weather Service Salt Lake City UT
129 PM MST Tue Nov 11 2025

Forecast is based on forecast start time of 1300 MST on November 11.
If conditions become unrepresentative...contact the National Weather
Service.

.DISCUSSION...For the next couple of days conditions over the fire are expected
to be warm and dry as high pressure remains in control of the
region. An increase in southwesterly winds will spread over the
area from Wednesday through Friday, with Thursday marking the peak
for wind speeds. Gusts on Thursday are expected to range from 30
to 35 mph during the afternoon hours, with gusts of upwards of 40
mph on higher exposure terrain. In addition to the uptick in
winds, afternoon min RH will still bottom out around 20-25 percent
on Wednesday and 25 to 30 percent on Thursday before finally
increasing by upwards of 20 percent on Friday as our next storm
system starts moving into the area.

As far as precipitation potential goes with this upcoming storm,
there is still quite a bit of uncertainty. Current model forecasts
suggest anywhere from about 0.05 inches of liquid equivalent to
0.65 inches of liquid equivalent (25th to 75th percentile). Snow
potential ranges from a trace to 2-3 inches. On the extreme ends
(10% chance), if the storm comes in much stronger then expect
upwards of 5 inches of snow with around 1 inch of liquid
equivalent... but on the weaker side expect nothing in terms of
precipitation (storm continues to track farther south). Timing-
wise, anticipate precipitation to begin on Friday morning, peaking
Friday afternoon, then fading through Friday night and Saturday
morning. Even if we end up with little to no precipitation, cooler
temperatures and higher RH will be overall trend through the
weekend.
