Area Forecast Discussion

National Weather Service Flagstaff AZ

945 AM MST Fri Dec 12 2025



.SYNOPSIS...High pressure will continue to bring well above 

normal temperatures and dry weather to the region into next week.



&&



.DISCUSSION...For today, an anomalously strong high pressure 

system will remain in place across northern Arizona, leading to 

another round of dry weather and near record warmth. High 

temperatures are expected to be between 10-20 degrees above 

average. Yesterday, a high temperature of 68 degrees was observed 

at the Flagstaff Airport. This tied the daily record set in 1950.

Flagstaff may tie or break today's daily high temperature record 

of 64, set all the way back in 1921.



This unusually strong high pressure system will largely dominate

northern Arizona's weather through next week, with fair weather

and near record warmth forecast to continue. On Sunday and 

Monday, high temperatures may dip a couple of degrees due to 

passing high clouds and influences associated with a weak 

shortwave trough forecast to overtop the ridge. Otherwise, light 

winds are forecast through Tuesday. On Wednesday, the ridge 

flattens, resulting in breezier southwest winds with speeds in the

10-20 mph range.
