Weather Underground Forecast for Friday, Feb. 21, 2014
A cold frontal boundary will extend from the Great Lakes to the eastern Gulf Coast on Friday, while an onshore flow will bring light to moderate precipitation to the Pacific Northwest.
A relatively strong cold front will stretch from the Southeast to the Great Lakes on Friday, pushing an active weather system across several regions. Severe thunderstorms will be possible over Florida, Georgia, the Carolinas, Virginia and Maryland, while more moderate thunderstorms are expected to develop behind the cold front. Meanwhile, low pressure along the northern portion of the cold front will trigger rain, freezing rain and sleet across parts of the northern Mid-Atlantic and New England. This system will also bring a chance of spotty snow showers to the Great Lakes and the upper Midwest, while the southern Plains will stay mostly clear of wet weather.
A separate cold front will extend from the upper Intermountain West to the central Plains on Friday, as pockets of heavy snow showers will be possible across the central and northern Rockies. Just to the west, an onshore flow from the Pacific will bring rainy weather to western Washington and northwestern Oregon, while snow showers can be expected at higher elevations. The Southwest will stay clear of precipitation on Friday due to a ridge of high pressure along the coast of southern California.
Temperatures in the Lower 48 states Thursday have ranged from a morning low of -11 degrees at Yellowstone, Wyo. to a high of 90 degrees at Harlingen, Texas
