An upper-level low located over the Great Basin produced cooler than normal 500 mb temperature of between -9 and -10C and also some upper-level diffluence with a 50-60 kt jet at upper-levels. Moisture levels were also above normal with precipitable water values between 1.0-1.3 inches. The combination of all of these factors resulted in sufficient instability with MLCAPE values approaching 1000 J/KG while DCAPE values were approaching 1500 J/KG. Thunderstorms began to develop during the early to mid-afternoon hours across most of southern and central Arizona, with strong to locally damaging winds as well as dense blowing dust being the main hazards along with locally heavy rainfall. One of the damaged areas came just northwest of Stanfield, where there were multiple downed power poles as well as a rolled over RV. There were also visible photos from social media as well as from seasoned storm chasers of a couple of landspouts, one near damaged area just northwest of Stanfield and another over Buckeye. With respect to the landspout that developed just northwest of Stanfield, there was no confirmation that it was responsible for the damage observed, which most likely was due to downburst wind. No injuries were reported with these thunderstorms.

Reported by: Storm Chaser

Multiple storm chaser photos show a landspout tornado developed northwest of Stanfield. It appeared to be moving northeast along a thunderstorm outflow through open farm fields. The exact location, timing, path length, and width were all estimated based on the photos and radar. It is unknown if the landspout caused any property or crop damage and no damage survey was conducted. An RV did flip and around 50 power poles did fall in this area, but these reports were attributed to downburst winds due to nearly all power poles falling to the north. No injuries were reported.

Multiple reports from storm chasers and local media of multiple downed power poles, trees, flipped irrigation pivots, and a rolled RV along and just east of SR-347, northwest of Stanfield. The local utility company reported around 50 downed power poles across the area, most of which were blown toward the north. There was a confirmed landspout in the general area as well, however, there was no evidence that it was the cause of any of the damage.
