Arizona weather forecast: Phoenix weather cooling trend brings wind and high fire danger this weekend

Comfortable temperatures coming to Arizona thanks to northern storm system

Sunday's temperatures hovered in the mid 90s in the Valley, as strong wind gusts swept across the state. A storm system to the north is bringing the slight cooldown to Arizona.

PHOENIX - After an unusually warm start to the week, the region is wrapping up the week with "cooler" temperatures this weekend.

Sunday:

Sunday was a warm, sunny and windy day across Arizona.

Temperatures cooled down compared to previous days, but the winds turned up. In northern Arizona, wind gusts reached 40 to nearly 50 mph Sunday evening, and the winds will stay breezy through the overnight hours. The Valley saw gusty winds in the afternoon and evening as well, and the winds will eventually lighten overnight.

Wind advisories remain in effect for far western Arizona through 11 a.m. Monday morning, as the winds will gust up to 60 mph overnight for areas including Lake Mead, Lake Havasu and Lake Mohave. There is high fire danger across the state, thanks to the wind, dry air and dry ground.

Critical fire weather is in place for much of northern Arizona due to gusty winds and low humidity.

Phoenix weather cooldown brings high fire danger

A new weather system lowers weekend temperatures in Phoenix but raises wildfire risks across Arizona due to high winds.

Looking Ahead:

For most of the state, Monday will not be as windy as Sunday, but there will still be noticeable breezes up to around 30 mph. It will be cooler for all, with temperatures dropping into the 60s and 70s in the high country, and into the upper 80s in the southern deserts, including the Valley.

Temperatures will warm back to near-normal highs and lows by mid-week, and slightly above average by next weekend.

What Happened This Weekend:

Saturday was a hot start to the weekend with Phoenix hitting a high of 100 degrees, which is 6 degrees above average.

Incoming weekend storm to bring cooler temperatures

While the Valley hit a Saturday high of 100 degrees, we will trend toward below-average temperatures as a large weather system moves in from the West.

Phoenix hit a high of 98 degrees on Friday, which is just four degrees above normal.
