WeatherBug Meteorologist Todd Nelson has the latest in his exclusive WeatherBug National Outlook. Large stretches of the central U.S. from the Rockies to the Plains will have a messy day. Heavy snow will continue to plague the Rockies into the northern Plains and Upper Midwest. Highs winds gusting in excess of 35 mph will cause visibility to drop to near zero, making travel a treacherous task. Blizzard conditions are likely in parts of northern New Mexico, Colorado, Wyoming and Montana. Across the western Great Lakes, the storm will produce a wintry mix of snow, sleet and freezing rain as warmer above-freezing air tries to stream northward ahead of the storm. Even warmer, mid-40s to low-50s air will produce a cold rain across the rest of the Midwest and Mississippi Valley. Snow is lingering from Montana into northern Arizona this morning. On top of the fresh powder, a renewed arctic blast is producing sub-zero temperatures across Montana and Idaho, with teens and 20s extending across the Great Basin and into the mountainous Southwest. The only places west of the Rockies that will not see any snow will be the Northwest and southern California, where a bit of doldrums will produce periods of clouds and sunshine. Temperatures will be in the 40s, with a few 50s in southern California. Quiet weather will also be the norm across the southern Plains, Texas and the East Coast. A bit of a winter warm-up will send temperatures in the 70s across the southern Plains, western Great Lakes and the Deep South. The Northeast will still remain cold and snow-covered, with 30s common. The Mid-Atlantic will be in the 40s and the Southeast will see 50s and low 60s this afternoon. Be sure to keep your WeatherBug active to receive the latest weather in your neighborhood.
