Cold Blast and Nor'easter to Impact Central and Eastern U.S., 10-17 to 10-19
Updated Sat Oct 17th 2026, 10:05am PDT

Over the weekend, much of the central, southern, and eastern United States will experience significantly cooler temperatures, with frost and freezing conditions expected from the Plains to the East. A strong cold front will sweep across these areas, bringing a colder and drier air mass. In the Great Lakes and parts of the Northeast, especially higher elevations, there will be a mix of rain and snow early Saturday. This will occur as colder air aloft interacts with existing precipitation.

Nor'easter Brewing on the East Coast

This weekend, a developing coastal storm, known as a Nor'easter, will form near the Carolina coast. This system will cause unsettled weather along the Mid-Atlantic through Monday. Expect heavy rain, strong winds, and hazardous surf conditions. The potential for coastal flooding and beach erosion is significant, depending on the storm's path and strength.

Fire Weather Concerns in California

Meanwhile, in California, dry conditions and strong winds will increase the risk of fires through Sunday, especially in areas prone to Santa Ana winds. This is due to a strong pressure gradient in the region. Be cautious, especially in wind-prone areas.

Rainy Weather in the Pacific Northwest

In the Pacific Northwest, there will be light showers this Saturday, mainly in coastal areas and the northern Cascades, as a weak weather system approaches. Additional showers are possible in the Southwest through Monday, due to lingering disturbances.

Temperature Drop Alert
