A strong storm system is stretched across the Rockies and Plains on Tuesday, bringing a wide variety of winter weather to large chunks of the U.S.
Winter weather advisories and storm warnings are now in effect over the Plains into the 中西部 on Tuesday into Wednesday.
The system is tracking northeast and is heading toward southeastern Canada by midweek.
But its snow and freezing rain will produce hazardous driving conditions.
Snowfall amounts of 6 至 8 inches will develop over parts of Iowa into southern Wisconsin and parts of west-central Michigan.
另外, a front is moving onshore in the Pacific Northwest.
That system will bring rain across the region late Tuesday before turning to snow at higher elevations.
Snowfall amounts of 12 至 18 inches are expected over the Cascades and the northern Intermountain Region.
