Weather Underground Forecast for Friday,February 27,2015
A low pressure system will affect the western third of the country on Friday, while an arctic high pressure system will slide across the Plains and the Midwest.
An area of low pressure will sink south southeastward over the Pacific Northwest, the Great Basin and the Southwest. This system will usher light to moderate rain across western Washington, western Oregon and northwest California during Friday morning. A mixture of rain and snow will affect the Cascades, the northern Rockies, the Great Basin and the Sierra Nevada. During the second half of the day, this system will usher showers across southwest California and the Desert Southwest. Moderate snow will begin to impact the southern Sierra Nevada, the Wasatch and the southern Rockies.
Meanwhile, an arctic high pressure system will shift slowly southeastward over the Plains and the Midwest. Upslope flow will generate moderate to heavy snow over the southeastern corner of the Rockies, as well as the southern Plains. An onshore flow from the Gulf of Mexico will interact with this air mass, creating an area of rain and freezing rain over central and southern Texas. In addition, bitter cold conditions will affect the northern Plains, the Midwest, the Ohio Valley, the Mid-Atlantic and New England. Wind chill advisories are already in place for eastern North Dakota, northwest Minnesota and portions of Indiana.
The tail end of a cold front will shift over the Gulf of Mexico and the western Atlantic. This frontal boundary will bring chances of showers and thunderstorms to southern Florida. Stormy weather will likely wind down by the afternoon.
