Overview
- Showers and isolated thunderstorms return in waves this weekend, with several markets noting a mostly sunny Saturday before new rain arrives late Sunday into Monday.
- The Storm Prediction Center highlights a slight to marginal severe risk along and south of I-80 this weekend, and a 15% severe probability Monday for parts of southeast Nebraska, Iowa, and Missouri, with large hail, 65 mph gusts, an isolated tornado, and localized flooding possible.
- A more dynamic Pacific storm moving ashore will tap an upper low from the Gulf of Alaska and deliver heavier West Coast rain, where 1 to 2 inches are expected and up to 4 inches could fall in coastal ranges.
- Marine conditions on the California coast worsen Saturday as thunderstorms may produce gusts strong enough to capsize small boats, so anglers are urged to plan quick access to safe harbor.
- A marked warm-up follows for many regions next week, with highs in the 70s and even low to mid-80s in places like the Northeast and Upper Midwest, which will boost instability and support more thunderstorms Monday and Tuesday.
