Update: Arizona, South Carolina Storms Evolve Under Persistent Slight Risk Today — SevereWX

Folks, as we flagged earlier with scattered moisture sparking isolated severe potential across the Southwest and Southeast, the situation is evolving just as expected. The Storm Prediction Center (SPC) has maintained its Slight Risk for Sunday, July 12, now zeroing in on Arizona and South Carolina specifically. Looking ahead, Vermont enters the Slight Risk zone on Tuesday, July 14.

A Slight Risk means there's a chance for isolated severe thunderstorms—nothing widespread, but enough to warrant caution in these spots. We're talking potential for damaging wind gusts up to 60 mph or more, isolated large hail around quarter-size, and a very low-end tornado possibility where storms intensify.

In Arizona, monsoon moisture and daytime heating are fueling pulse storms, particularly over southern areas, capable of packing those gusty winds as they spill out toward lower elevations this evening. South Carolina faces similar isolated thunderstorm development amid humid conditions, with wind the main concern. By Tuesday, cooler instability over Vermont could trigger rogue severe cells.

If you're in these areas, stay tuned to your local National Weather Service office for the latest advisories. Have a severe weather safety plan ready—know where to go if storms rumble through.
