Weather Underground Forecast for Wednesday,October 26,2016

A cold frontal boundary will slide across the West Coast on Wednesday, while an area of low pressure shifts over the Midwest.

A low pressure system will move north northeastward from the coast of northern California to the coast of British Columbia. A cold frontal boundary associated with this system will extend south southwestward. As this frontal boundary moves over the West Coast, it will produce periods of light to moderate rain in northern California, Oregon, Washington, northern Idaho and western Montana. High elevation snow is also expected for the northern Cascades and the northern Rockies. A ridge of high pressure will bring a dry weather pattern to the Great Basin and the Southwest on Wednesday.

Meanwhile, a low pressure area will transition east northeastward across the Midwest and the lower Great Lakes. This system, combined with a cold frontal boundary, will generate showers and thunderstorms across the Mississippi Valley, the Tennessee Valley, the Midwest and the interior Mid-Atlantic. Another area of low pressure will push eastward over south central Canada. A mixture of rain and snow will develop ahead of this system over the upper Midwest. Most of the Deep South and the Southeast will stay clear of precipitation, with the exception to scattered storms along eastern Florida and the central Gulf Coast.
