A storm system  crossing the West will reach the central Plains on Tuesday and the Great Lakes region by Thursday. Locally severe thunderstorms will accompany the system from parts of the Plains into the Mississippi Valley. By week’s end, rain associated with the storm could reach 1 to 3 inches  from the central Plains into New England.
Meanwhile, dry conditions and gusty winds will increase the threat of wildfires  on the southern High Plains.
Looking ahead, the 6- to 10-day outlook  calls for above-normal temperatures across the central one-third of the U.S., while cooler-than-normal weather will prevail in southern Florida and the West. Meanwhile, below-normal precipitation in northern California and across the nation’s southern tier will contrast with wetter-than-normal conditions in the Northwest and the upper Great Lakes region.
