Cool and Dry in the East; Turning Stormy in the Northwest

Much cooler temperatures behind a cold front will bring a feeling of fall to the East Coast today. In addition, an active fall storm pattern developing in the Pacific Northwest this week will bring areas of heavy rain and high elevation snow. Northern California will benefit from rainfall this week that will aid firefighters given the recent large wildfires. Read More >

The pleasant autumn weather will continue. After a cool start to the morning, temperatures will reach the 70s by early afternoon. The humidity will remain low. South winds will gradually return, but wind speeds will remain light.
The surface high that has kept the area cool will slowly drift east away from the region, allowing for the return of south breezes 10 to 15 mph and highs in the upper 70s and 80s each day. Humidity will slowly be on the rise, with a fast moving system by Friday bringing a few showers and thunderstorms to the area. No severe weather is expected, though occasional lightning strikes will pose a hazard for outdoor activities.
There will be a low potential for showers and a few thunderstorms on Saturday, mainly across eastern zones. The better threat for more organized thunderstorms will be late Saturday into Sunday. A few storms will have the potential to be strong with gusty winds, hail, and lightning right along a strong cold front. We'll continue to refine the storm hazards as we get closer to the coming weekend.
