Area Forecast Discussion

National Weather Service Tucson AZ

1252 PM MST Fri Dec 12 2025



.SYNOPSIS...



Dry and warm weather will continue through the end of 

next week. High temperatures will be well above normal, with some 

locations approaching record levels through the weekend.



&&



.DISCUSSION...



Anomalous mid-level heights amid stout ridging over the western 

United States will dominate the upper level pattern into next 

week. While the second half of the coming week should see a less

amplified pattern, high pressure will remain over the desert

southwest and keep the warm and dry conditions in place. High

temperatures will be well above normal with forecast highs

currently 10-15 degrees above normal through the coming seven day

period.



The only other notable weather during this stretch will be a

switch in the wind direction Sunday into Monday as the ridge axis

transitions to our east and winds become easterly. 10-15 mph

sustained winds with gusts to 25-30 mph are likely Sunday

afternoon, mainly in locations exposed to easterly winds. The

strongest east to southeast winds are expected through the upper

Gila River Valley near Safford, across eastern Santa Cruz/western

Cochise counties, and in the Tucson metro area.

.FIRE WEATHER...



Dry conditions are expected through the end of next 

week, along with high temperatures 10-15 degrees above normal. 20-

foot winds will generally be 15 mph or less and terrain driven the 

next seven days, except Sunday into Monday when east-southeast winds 

of 10-15 mph and gusts to 25-30 mph are expected. Minimum RH values 

at all elevations will generally be in the 15-25 percent range into 

the middle of next week, with the potential for a slight increase 

into the 20-35 percent range across eastern areas (Cochise, Graham 

and Greenlee counties) on Monday.
