Area Forecast Discussion

National Weather Service Flagstaff AZ

117 PM MST Sat Mar 21 2026



.SYNOPSIS...Summer-like high pressure will continue into next week,

with temperatures reaching up to 25 degrees above normal. Please 

exercise appropriate precautions if you are planning on any 

outdoor activity. Breezy southwest winds and low humidity are also

expected.



&&



.DISCUSSION...A trough moving across the northern part of the

country will flatten out our record breaking ridge over the next

couple days which will drop our temperatures back about 5 degrees.

However despite this minor cooldown, we are still in record

breaking territory for the next week with temperatures warming up

again midweek as the ridge starts flexing back north. Unfortunately

no precipitation is in sight for the next week. Low humidity 

continues to dry out our fuels in the national forests but luckily

the winds have been staying light enough that we're not reaching 

any Red Flag criteria at this time. Having said that, with the 

higher amount of people using the forest and fleeing the lower 

desert heat at this time, please use caution with any type of open

flame activities at the campgrounds.
