Check the forecast before you set up for any cookouts this Fourth of July holiday. Dangerously hot weather threatens parts of the Southwest and the Pacific Northwest, while severe thunderstorms pose a risk in the Midwest.

The mid-Atlantic and Southeast can also expect storms — a continuation of the “unsettled weather” the region has seen lately, in the words of the National Weather Service. And while extreme heat has eased its grip on much of the Southeast, heat advisories continue in parts of North Carolina and Florida.

The past few weeks have been grueling for vast swaths of America. A heat dome brought brutal temperatures to areas including Texas and the South. High humidity made the heat particularly dangerous, and in some cases, deadly.
