A pair of cold fronts will affect the eastern half of the country on Friday, while a Pacific system approaches the West Coast.
An elongated area of low pressure will shift eastward across southeast Canada. A cold frontal boundary associated with this system will stretch south southwestward across the eastern Great Lakes, the interior Mid-Atlantic, the Southeast and the Gulf Coast. This frontal system will initiate light to moderate rain and embedded thunderstorms across the Eastern Seaboard. Scattered showers and isolated thunderstorms will also be possible in the southern Plains and the western Gulf Coast. A separate cold front will extend west southwestward from the western Great Lakes to the upper Intermountain West. Strong to severe thunderstorms will fire up along and ahead of this frontal boundary across the central Plains, the middle Mississippi Valley and the Midwest. Severe thunderstorms will be possible in eastern Kansas, northern Missouri, southern Iowa and northwest Illinois. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. A mixture of rain and snow will also affect the northern Rockies and the northern high Plains.
Meanwhile, a Pacific system will approach the coasts of northern California and Oregon. Showers and isolated thunderstorms will pop up across Oregon, northern California and northwest Nevada. A warm and dry weather pattern will persist over the Southwest on Friday. Afternoon temperatures will range between the 90s to 100s across the Desert Southwest.
