Winter storm systems to hit both coasts in one-two punch, as West surveys wind damage

A cold front from Canada will keep temperatures chilly into next week

A two-tiered storm system is set to hit both coasts on the heels of a week of dangerous wind gusts and heavy rain

The low-pressure system will head east, tracking across Colorado's Rockies and the Plains as well as dusting widespread areas, according to the National Weather Service.

To the southwest, forecasters say several locations may receive a few inches of heavy snow, creating hazardous travel conditions, before the system moves into the lower Mississippi Valley on Sunday.

Moderate to heavy rainfall is also expected, potentially leading to flash flooding along the frontal boundary.

In the Midwest, a high-pressure system from Canada will move south, keeping temperatures frigid into next week, the Weather Service said.

Leeward areas can expect heavy lake-effect snow through Saturday evening, though more rain and a wintry mix will impact the Plains and Mid-Atlantic to the Northeast into next week.

California, which was battered by intense winds earlier this week, can anticipate rain in lower elevations and mountain snow.

On Sunday morning, a Pacific Northwest front will begin moving inland to the Great Basin. By afternoon, the system will cross Washington and Oregon into Northern California.
