As seen in the map above, winter is in full force in two parts of the United States, with the Southwest and Great Lakes both getting watches and warnings from the National Weather Service (NWS).
Winter weather warnings and advisories are in place for five U.S. states as more snow is expected to fall over the Great Lakes region and parts of the southwest in the coming days.
The National Weather Service (NWS) has issued alerts concerning snow and strong winds for parts of Alaska, Colorado, Michigan, New York and New Mexico, warning of reduced visibility and snow accumulations at higher elevations.
The NWS says on their home page:
A winter storm will begin to impact portions of the Southern Rockies and High Plains today. Light to heavy snowfall will be possible through Thursday especially across southern Colorado and northern New Mexico.
In their Short Range Public Discussion of Dec 13, they add:
Moderate to heavy snow and below average temperatures likely over portions of the Southern Rockies/High Plains through early Friday morning.
A digging upper low will be responsible for the winter storm that impacts portions of the Southern Rockies/High Plains beginning today. Moisture advection into the region from the southeast will interact with a weak surface front as well as the terrain of northern New Mexico and southern Colorado to produce rain over the lower elevations, a wintry mix in the highlands and snow in the mountains. Snow levels remain an uncertainty with potential for accumulating snow as low as 5,500′ and as high as 7,500′. Significant rainfall and scattered thunderstorms are also likely across east, central and southeast New Mexico. Below average temperatures are expected from southern Colorado to west Texas over the next couple of days as well.
