Weather Underground Forecast for Friday, June 17, 2016
A cold frontal boundary will bring active weather to the Southeast on Friday, while a trough of low pressure keeps wet weather in the forecast for the Northwest.
A low pressure system will drift east southeastward across the Mid-Atlantic. A cold frontal boundary associated with this system will extend west northwestward from the southern Mid-Atlantic to the central Plains. This frontal boundary will collide with warm and humid air from the Gulf of Mexico, which will ignite strong to severe thunderstorms across the Plains, the Deep South, the Southeast, the Mid-Atlantic and the Ohio Valley. Severe thunderstorms will be possible in Alabama, Georgia, northern Florida and southern South Carolina. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. Most of New England will experience cool and dry weather on Friday.
Meanwhile, a ridge of high pressure will inch northward and amplify across the Southwest. Afternoon temperatures will spike well above the century mark across the Four Corners and the southern high Plains.
A trough of low pressure will linger over the Northwest. A cool weather pattern will persist in northwest California, western Oregon and western Washington. Scattered showers and thunderstorms will affect parts of the Northwest, the upper Intermountain West and the northern high Plains. High elevation snow will also be possible in the Cascades and the northern Rockies.
Temperatures in the Lower 48 states Thursday have ranged from a morning low of 26 degrees at Winnemucca, Nev. to a high of 104 degrees at Roswell, N.M.
