Heat Returns Across U.S. as Weekend Storms Bring Local Flood Risk

A strengthening western ridge will push heat and humidity eastward, threatening triple‑digit heat‑index values for some communities.

Overview

  • After a brief cool, drier period behind a cold front, heat and humidity will surge back this weekend and persist into next week with many highs in the 90s and some locations feeling like triple digits.
  • Scattered, mesoscale‑driven storms are forecast each afternoon and evening, and where storms train or concentrate they could drop locally 2 to 3 inches of rain and produce isolated flash flooding.
  • The Northeast will enjoy a short respite of cooler, less humid weather for the weekend before warmth and higher humidity return early next week.
  • Parts of the Southwest remain under official extreme‑heat products with near‑record daytime highs, very warm overnight lows that limit nighttime relief, and continued public‑safety warnings.
  • NOAA drought updates show worsening conditions in Minnesota and the NWS has issued Red Flag Warnings for north‑central Washington, creating heightened risks for wildfire spread, smoke impacts, and water stress.
