Weather Underground Forecast for Friday, December 14, 2012.
Active weather continues for the West on Friday, while the East remains mild and dry. A trough of low pressure and associated cold front moving across the Desert Southwest will produce more rain and mountain snow showers on Friday. Precipitation in Arizona will diminish into the afternoon, but heavy rain and snow will persist across New Mexico, Colorado, and Utah throughout the day. Snowfall accumulations in northern Arizona and northern New Mexico will range from 4 to 8 inches, with up to 12 inches likely above 7,000 feet. Just to the north in southwestern Colorado expect 5 to 9 inches of new snow, with over a foot at highest mountain peaks. Southern Utah may see up to 16 inches of snow at the south facing slopes, while most of the area will see 3 to 5 inches of snow.
Meanwhile, in the East, a ridge of high pressure remains the dominant weather feature, maintaining dry conditions across the Eastern Valleys and East Coast. To the North, a frontal boundary lingers over the Great Lakes, producing a few more scattered snow showers throughout the day. The back side of this system will continue pulling cooler air in from Canada, allowing for highs to remain in the 30s for the Upper Midwest and in the 20s across the Northern Plains.
Temperatures in the Lower 48 states Friday have ranged from a morning low of 1 degrees at Princeton, Minn. to a high of 73 degrees at Stuart, Fla.
