A Winter Storm Warning remains in effect for Northwest Indiana and the northern suburbs while much of the Chicago area has been downgraded to a Winter Weather Advisory.

The National Weather Service tailors its winter warnings based on what’s considered “disruptive weather” for each region of the U.S.

A reinforcing shot of Arctic air will accompany a fast-moving clipper system this weekend, spreading a wintry mix, bursts of heavy lake-effect snow, and gusty winds that could reach to 70 mph across parts of the region.

For the West Slope Northern Sierra Nevada, including Blue Canyon, a winter weather advisory is also in effect to 10 a.m. Friday. Snow totals are expected to reach three to six inches south of Highway 50, with 12 to 18 inches at the highest peaks. Gusty winds up to 50 mph are also expected.

The National Weather Service said 8 to 10 inches of snow could fall by Monday morning. Chicago has activated more than 250 salt spreaders to keep roads clear for the morning commute.

AROUND 3,000 were left without power after Storm Claudia hit the country with high winds and heavy rain. And Ireland has now been warned to brace for possible SNOW, with forecasters warning

Winter storm warnings spanned Mono County, as well as the Sierra Nevada from Yosemite National Park to Tulare County.

Storm Claudia has caused chaotic weather across the country, and a cold snap is on the way, potentially bringing snow. The storm, named by the Spanish meteorological service, struck the UK on Friday, having a "devastating" impact in Wales, where a major incident was declared.

Downpours which battered the UK on Friday will be replaced with below-freezing temperatures and potentially snow in the coming days. The UK Health Security Agency (UKHSA) issued the cold weather warning for parts of the Midlands and northern England from Monday as temperatures are set to drop by 8 degrees.

A less stable pattern with winds, cooler temperatures, rain and mountain snow should continue off and on for the rest of the forecast period
