A pair of frontal boundaries will affect the eastern half of the country on Friday, while a ridge of high pressure builds over the Southwest.
A cold frontal boundary will extend southwestward across New England, the Ohio Valley, the middle Mississippi Valley and the southern Plains. This cold front will move slowly eastward, generating showers and thunderstorms across the Mid-Atlantic, the Southeast, the Deep South and the southern Plains. A wave of low pressure will form along the tail end of this frontal boundary as warm air moves across the central Plains. This wave of low pressure will generate showers and thunderstorms over the northern and central Plains. Scattered showers will also be possible over the upper Intermountain West.
Meanwhile, a secondary cold front will stretch west southwestward from southeast Canada to the upper Mississippi Valley. This frontal boundary will interact with relatively warm air, producing scattered showers and thunderstorms from northern New England to the upper Mississippi Valley. Cool and dry air will settle in north of the frontal boundary over the upper Midwest.
Most areas west of the Continental Divide will stay clear of precipitation on Friday. A ridge of high pressure over the Southwest will bring hot afternoon temperatures to the Desert Southwest and the southern Plains.
