The Storm Prediction Center has issued a Moderate Risk for severe thunderstorms for portions of the Midwest. An ongoing derecho, currently producing widespread damaging winds is expected to continue to move rapidly east across portions of southern Wisconsin and northern Illinois, including the Chicago Metro area this afternoon. Expect strong to severe storms to continue farther east into lower Michigan and Indiana, while extending south into central Illinois this evening, before dissipating overnight. These storms are developing ahead of a cold front that is forecast to gradually push east from Great Lakes into the Northeast, while settling south into the mid Mississippi and Ohio valleys over the couple of days. Ahead of the front, above normal temperatures are expected to continue into midweek, with Heat Advisories in effect for portions of the Northeast, including the I-95 corridor from New York to southern Maine. Expect the approaching cold front to bring more widespread shower and thunderstorm coverage across the Northeast and Mid Atlantic late Tuesday into Wednesday, while knocking down temperatures by midweek. A pair of cold fronts producing windy conditions, but little precipitation, will support critical to elevation fire weather conditions tomorrow across portions of the Northwest, northern Rockies and Great Basin. A Fire Weather Watch is in effect for Tuesday for portions of eastern and central Washington to northwestern Nevada and northern California. Red Flag Warnings are also in effect on Tuesday for portions of central and western Montana, central and western Wyoming, southern Idaho and northern Utah.
