Southern Arizona Storms Intensify for 55-70 MPH Evening Wind Threat

Storms are firing up along the Gila and White Mountains in southern Arizona, poised to deliver severe wind gusts of 55-70 mph late this afternoon through evening. The Storm Prediction Center highlights an 80% chance of a Severe Thunderstorm Watch as these storms deepen and push southwest into southeast and south-central Arizona.

Hot, moist air near the surface combines with steep lapse rates, fueling MLCAPE values of 1000-1500 J/kg. Easterly winds aloft at 4-6 km will aid cold pool organization, boosting downburst potential. Expect hail up to 1.25 inches too.

This setup taps into the monsoon flow on the edge of a stubborn upper high over Utah and Colorado. Radar and satellite show early cumulus towers building now, with coverage and intensity ramping up over the next 2-3 hours.

Areas from the mountains toward Tucson and lower deserts could see damaging winds disrupt power, topple trees, and scatter debris. Stay tuned to local NWS updates.

Preparedness: Secure outdoor items, avoid flooded roads, and have multiple alert sources ready. Monitor radar closely this evening.
