Rain and Thunder in Central and Eastern U.S., Cool in Northwest 09-12 to 09-14
Updated Sat Sep 12th 2026, 5:56am PDT

Get ready for a mix of rain and thunderstorms if you are in the Central to Eastern parts of U.S. this weekend as a strong cold front moves through. Meanwhile, the Northwest and Northern Rockies will experience cooler, wet conditions. Let's dive into the details and see what to expect in your area over the coming days.

Central and Eastern U.S.

Today and tomorrow, a defined cold front traveling from a big storm over Hudson Bay is making its way across the Central and Eastern U.S.. This means we can expect showers and thunderstorms from the Northeast to the Plains states. The most intense rain is set to drench areas in the Ohio Valley, Mid-Atlantic, and Northeast today and into tomorrow, as warm moist air moves in. With slow-moving storms, already wet ground, and urban areas in the path, there's a flash flood risk from Richmond, VA up through New York, NY.

Northwest and Northern Rockies

Tonight, a strong weather system coming in from the Pacific will bring much-needed rain to the Northwest. This will be followed by another front moving in tomorrow. The rain here is due to a low-pressure system and is expected to bring cooler weather to the Northern Rockies. Expect temperatures in the 60s and 70s, which should be a refreshing change!

Southern Rockies and Plains

Thunderstorms will persist daily across the Southern Rockies and Four Corners area. By tomorrow, a northward-moving front will interact with a strong low-level wind to trigger more showers and storms in the Plains, with potential flash flooding. While some areas cool down, the Southern Plains and Mid-Mississippi Valley will endure sweltering heat, as the front won't reach beyond the Oklahoma Panhandle.
