Thunderstorm Watch Issued For Eastern Phoenix Metros to Tucson As Storms Forming Off High Terrain Move Downward This Evening Along With Storms At Hoover Dam; Details


Arizona Weather Force has issued a Thunderstorm Watch. Storms are expected to form over the high terrain, including Flagstaff today (where it did not yesterday).  These storms will move off the Mogollon Rim and impact communities in the Eastern half of Maricopa County, or the Eastern Phoenix Valley zones, extending down through Tucson.  Another focus is the system out of Las Vegas so read on for details.

Instability this morning is not strong like it was yesterday to the north/northwest of Maricopa County, so the odds of another repeat for Prescott are low.  This is due to the debris clouds (mid/upper-level cloud deck) covering the area from storms north of the region overnight.  This hampers instability with less heating at the surface for parcels to rise quicker.  The sky is much clearer from Payson and Phoenix southward to South/Southeast Arizona.  This will be the main focus spot today so I’ll talk about that.  Instability is already high across those areas.  Storms forming from the Gila County to Safford areas will be one of the outflow boundaries to make it westward through Eastern Maricopa County down through I-10 and to Tucson today/this evening.  So while not the major damaging wind event a couple to a few days back, it will be a ‘mini’ version with up to 40 mph wind gusts (isolated 50) being possible, thus it is a magenta shade on the article map for isolated severe storm dynamics, mostly larger hail.

The other outflow boundary will be from storms south of the international border.  This would shove outflow northward through Santa Cruz and Cochise County into the Tucson areas where the outflow from the east would meet.  Tucson’s forecast area proper stands the best chance at stronger storms as a result of this double outflow collision.  Colliding outflows can also bring a brief tornado spin-up.

The last area is the overnight focal spot with storms out of Las Vegas (Clark County).  These storms will cross the CO River Valley and affect areas around Bullhead City to Kingman, maybe even down near Havasu, so don’t be surprised of a light show there.

Arizona Weather Force is a custom weather alert service that began in September 2019 off of Southern California Weather Force and is regarded as the most accurate weather service in the state, offering custom alerts, maps, and models to help save life and property.  The work done here is never 100% accurate, but it comes pretty close.  Arizona Weather Force runs on zones, so if an event happens in a zone that is 10 miles from the border of your zone, the forecast is still valid to activate your zone’s alert system.  A company quote to the public is that of “The Joker” and tells other agencies in weather this all the time… “This world deserves a better class of meteorologist… and I’m gonna give it to them”… out-forecasting even the National Weather Service with lead-time and precision, which makes this service a focus of ridicule and envy in the weather community due to having such accuracy. Alerts issued here are issued custom from this office and this office alone. You may not even hear it elsewhere, but if one is issued near or in your area, listen up because “if you do not wish to die in weather, follow, it’ll save your life one day.”
