Arizona Lapse Rates Ignite 80 MPH Desert Gust Threat — SevereWX

Arizona's steep midlevel lapse rates and rich moisture are fueling a severe wind threat across southern and central deserts.

The Storm Prediction Center's Mesoscale Discussion 1606 highlights deepening cumulus fields in southeast Arizona, alongside ongoing thunderstorms along the Mogollon Rim. MLCAPE nearing 1000 J/kg signals robust destabilization, priming higher terrain for new storm development through the afternoon.

Midlevel easterly flow at 20-30 knots will steer these storms off the terrain and into lower desert elevations by evening. While activity remains isolated, organized clusters could unleash damaging gusts of 65-80 mph--enough for severe thunderstorm criteria.

Trends are under close watch, with a 60% probability of a severe thunderstorm watch in the next 1-2 hours covering parts of southern/central Arizona. The event runs until around 8 PM MST.

Residents in Phoenix metro and surrounding deserts should monitor radar closely as cells propagate westward. Power outages, downed trees, and hazardous travel are possible with any stronger outflows.

Preparedness Tip: Secure outdoor items, avoid flooded roads, and have multiple alert sources ready--like NOAA Weather Radio or SevereWX.net updates--to stay ahead of gust fronts.
