Area Forecast Discussion

National Weather Service Flagstaff AZ

145 AM MST Fri May 9 2025



.SYNOPSIS...An area of high pressure will bring above normal

temperatures and mostly dry conditions through the weekend.

However, there is a very slight chance for high elevation showers

on Saturday. A larger storm system will bring cooler and gustier 

conditions next week.

.DISCUSSION...A strong ridge is over much of the Southwest,

resulting in above normal temperatures and mostly dry conditions.

Expect daytime highs to land 5-10 degrees above normal through the

weekend, with mostly light winds. There is a chance a smidge of

moisture will creep into the state on Saturday, as the ridge is

more centered across western Arizona. Even with the potential weak

moisture push, activity will likely be limited to higher terrain.

And of this activity, we could see an isolated thunderstorm or two

due to the daytime heating combined with any orographic lifting. 



A large area of low pressure is forecast to push down the

California Coast by the beginning of next week, weakening the

previously mentioned ridge. As a result, daytime highs will 

slowly drop to below normal and winds will increase out of the 

southwest. We could see gusts between 35-45 mph, with locally

stronger gusts across downslope areas. Dry conditions are expected

during this timeframe, but with the recent moisture, fire weather

concerns are minimal. Model guidance suggests that we'll remain 

under a deep trough pattern through much of next week, but 

moisture appears to stay north of our state. There's still time 

for things to change, but for now, expect cooler and windier 

conditions moving into next week.
