Forecast Discussion:

Sky Harbor officially saw its first 100-degree F day of the year yesterday. In fact, the high temperature reached 102 degrees F, which tied the record high for the day. Ozone sat in the upper end of the Moderate Air Quality Index (AQI) category throughout the weekend. Now, let's talk about what's in store for this week...

Weather maps and satellite this morning reveal a large low pressure wave stretched along the West Coast. Over the few days, this wave will close into a circulation and slide southward along the California coastline. Then by Thursday, it will edge its way into Arizona. Another smaller wave will affect Arizona on Friday.

Weather-wise, this week will be a breezy one. The active weather pattern will support southerly or south-southwesterly winds each day, today through Friday. Temperatures will also back away from the 100-degree mark, with highs bottoming out in the upper 70s on Thursday. Skies should remain mostly or partly sunny.

Air quality-wise, the winds will have a plus and a minus. The plus is that winds are expected to help limit ozone levels, preventing any significant local build-up. Moderate ozone levels are possible on days with the lighter winds. The minus is that winds will be strong enough to cause dust. In particular, today and Thursday currently look to have the most widespread breezes and therefore, the greatest potential for dust.

Hourly forecast PM10 (dust) levels have thus been increased for the afternoons, particularly today and Thursday. Moderate PM10 levels will be possible several days this week. Industrial areas south/southwest of Phoenix will also likely see the highest AQI for PM10, since they often see elevated PM10 levels in the mornings.

Lastly, PM2.5 (smoke) levels should generally follow PM10 trends.

Check back tomorrow morning for the latest!

LAW ENFORCEMENT

Despite warnings, safeguard to prevent extremist training for law enforcement removed

In our latest coverage of so-called “constitutional sheriff” groups, AZCIR’s Isaac Stone Simonelli details a series of stark warnings from local and national civil rights groups sent to our state’s top government officials—and how those warnings ultimately failed to stop a rule change that opens a path for extremists to train Arizona law enforcement.

The new rule, as first reported by Isaac in 2022, shifts the responsibility of continuing education training oversight from the Arizona Peace Officer Standards and Training Board to law enforcement agency heads, including police chiefs and publicly elected sheriffs.

The change removes a longstanding safeguard for AZPOST to vet any continuing education training provided to Arizona law enforcement: In 2021, for example, AZPOST denied a training proposed by the Constitutional Sheriffs and Peace Officers Association, which has been labeled an extremist, anti-government organization by national experts.

In four separate letters to recipients ranging from Arizona Gov. Katie Hobbs to the U.S. Department of Justice, the civil rights and advocacy groups urged officials to prevent the rule change from taking effect on April 5. That deadline has since passed, and the rule is now active.

Find out what this means for Arizona, and what—if anything—our state is doing to address the change moving forward.

READ MORE: ‘Constitutional Sheriffs’ — An AZCIR series about an anti-government movement with roots in Arizona

Arizona ‘ground zero’ for extremist, anti-government sheriff movement

More than half of Arizona’s county sheriffs are at least partially aligned with a growing movement of so-called “constitutional sheriffs,” with an ideology that threatens to radicalize law enforcement by indoctrinating them with false legal theories about a sheriff’s authority over state and federal government, and a duty to nullify laws they interpret as unconstitutional.

Experts warn of extremist push to expand sheriffs’ role in elections

Election and domestic extremism experts warn that so-called “constitutional sheriff” groups are compounding problems created by disinformation campaigns and undermining public confidence in elections and law enforcement, setting the stage for situations that can lead to voter intimidation and ultimately subvert free and fair elections.

Rule change opens new path for ‘constitutional sheriff’ group to train Arizona law enforcement

A rule change by Arizona’s top law enforcement-certifying agency removes a safeguard against ‘extremist’ training for peace officers by allowing sheriffs and police chiefs more autonomy in determining what qualifies as mandatory continuing education credit.

How AZCIR identified Arizona’s ‘constitutional sheriffs’

Whether or not sheriffs adopt the core ideologies of the movement is more telling when it comes to how they approach their jobs—including how they interact with constituents and other government agencies—than whether they use the “constitutional sheriff” moniker.

Arizona-based sheriff group promotes members with ties to white nationalism

The Constitutional Sheriffs and Peace Officers Association has formally embraced some of its more radical members by promoting them into leadership positions. The public-facing change comes at a time of growth for the organization as it seeks to further expand its influence and ideology across the nation.
