Weather Underground Forecast for Friday,January 29,2016
A Pacific system will impact portions of the West Coast on Friday, while a pair of low pressure systems affect the northern tier of the country.
An area of low pressure will move onshore over British Columbia. A cold frontal boundary will extend south southwestward. A plume of moisture over the eastern Pacific will intersect this frontal boundary, which will lead to moderate to heavy rain and mountain snow from the Pacific Northwest to northern California. Winter storm watches are in place for portions of the Sierra Nevada, the Cascades and the Intermountain West. Heavy rain will bring threats of flash flooding to northwest California and southwest Oregon. Rain accumulations will range between 2 to 6 inches from western Washington to northwest California. Freezing rain will also be possible across the interior Pacific Northwest and the upper Intermountain West.
Meanwhile, a low pressure system will shift east southeastward over the eastern Great Lakes and the Northeast. Light to moderate snow will develop across parts of the upper Midwest and the Northeast. A separate system will slide across south central Canada. A warm frontal boundary will produce a mixture of rain, freezing rain and snow over eastern North Dakota, Minnesota, Wisconsin and northwest Michigan. A dry weather pattern will prevail from the southern Plains to the Southeast.
