Overview
- A cold front brought cooler, drier air for many locations this weekend, producing lower humidity and seasonable highs that improved outdoor conditions.
- Forecast models show heat and humidity returning early next week as a western ridge strengthens and tropical or monsoonal moisture returns, with highs in the 90s and heat indexes above 100°F in parts of the country.
- Scattered afternoon and evening storms will occur this weekend in several regions, and repeated or training storms could produce locally heavy rain and isolated flash flooding.
- Tropical updates show Dolly has degenerated to an open tropical wave with heavy‑rain risks for the Leeward Islands and nearby Caribbean areas, while the eastern Pacific is unusually active with Lowell, Karina and other areas forecast to strengthen.
- Regional extremes persist: Southern California remains under extreme heat warnings with triple‑digit inland highs, Southeast Texas is rapidly worsening into moderate drought, and isolated weekend showers are unlikely to erase broader rainfall deficits.
