Weather Underground Forecast for Saturday, Feb. 01, 2014
A cold front is expected to move over the Pacific Northwest and the upper Intermountain West on Saturday, while a separate frontal boundary will extend from the Southwest, over the southern Plains and across the Great Lakes.
A cold frontal boundary will trek across parts of the Southwest and the southern Plains on Saturday morning before lifting over the Mississippi Valley and the Great Lakes by the evening. This system will interact with a moist air mass from the Gulf of Mexico to produce rain, freezing rain and snow over portions of the southern Plains. As this system moves northeastward, freezing rain is expected to develop over the middle Mississippi Valley and into the Ohio Valley. By Saturday night, ice storms will move across parts of the Mid-Atlantic. Heavy snow is also expected to develop north of the frontal boundary in the upper Midwest and across the Great Lakes. This swath of snow showers will shift over northwestern New England towards the end of the day. Rain will also form over the lower Mississippi Valley, the Gulf Coast and the Southeast, while a lingering frontal boundary will trigger thunderstorms along the southern tip of Florida.
Out west, low pressure associated with a separate front will usher precipitation across the Northwest. Rain can be expected along the coasts of Washington, Oregon and northern California, while light snow will be possible in the Cascades and the northern Rockies.
Temperatures in the Lower 48 states Friday have ranged from a morning low of -27 degrees at Pine River, Minn. to a high of 82 degrees at Breckenridge, Texas
