Southwest U.S. Braces for Severe Storms and Critical Fire‑Weather Outlook June 26

The Storm Prediction Center issued an Extremely Critical fire‑weather outlook for central and southwestern Utah, northwest Arizona and southeastern Nevada, citing 40‑55 km/h southwest winds and humidity of 5‑15 % that could spark new ignitions and worsen existing wildfires. The agency also placed much of Utah, eastern Nevada, northern Arizona and surrounding areas in a Critical fire‑weather zone.

A severe thunderstorm watch was released for Colorado’s eastern plains, where forecasters expect large hail, damaging winds over 65 mph and a low tornado risk as storms move from the mountains eastward. Similar severe thunderstorm concerns were noted for Indiana, with heavy rain, flash‑flood threats and damaging wind forecasts for the southern part of the state, while heat and humidity are set to rise next week.

Additional hazardous weather includes gusty outflow winds up to 55 mph across central, western and northern New Mexico, and a meso‑scale discussion highlighting possible wind gusts up to 60 mph in central Virginia and the Delmarva region. A seasonal outlook predicts an above‑average monsoon for Utah that may ease fire danger by late July, though drought conditions are expected to persist through the summer.
