Arizona Clusters Charge Toward 80 MPH Desert Wind Hammers

Isolated thunderstorm clusters are organizing across southern and central Arizona this afternoon, primed to deliver severe wind gusts up to 80 mph as they spill off higher terrain into the lower deserts.

The SPC's Mesoscale Discussion 1606 highlights deepening cumulus over southeast Arizona and ongoing storms along the Mogollon Rim. Steep midlevel lapse rates, rich midlevel moisture, and MLCAPE near 1000 J/kg are fueling further destabilization. Midlevel easterly flow at 20-30 knots will steer these storms southwestward through evening.

Organized clusters could pack the most punch, with the most probable peak gusts at 65-80 mph. A severe thunderstorm watch issuance probability stands at 60%, potentially needed within the next 1-2 hours for parts of the region.

This setup echoes classic Arizona monsoon microburst potential, where outflows can slam desert valleys with little warning. Trends are being closely watched.

Stay prepared: Monitor local NWS updates, secure outdoor items, and have a plan for sudden high winds. Avoid travel under storms and seek sturdy shelter if gusts intensify.
