ECMWF broadens high pressure across the U.S. centered on the Great Plains later this month. Support from other models is favoring this solution although some AI models re-cool the East. The sensible weather is widespread anomalous warmth and increasing Great plains hot weather risk. The Southwest U.S. encounters early season clouds/thundershowers.

The updated Climate Impact Company summer 2026 outlook indicates a hotter than normal summer season across much of the U.S., especially the Northwest to California and Gulf States while wet climate suppresses anomalous heat risk in the Midwest. Drought expands northwestward in the West and develops Mid-south to Texas later in the summer season.
