Looking ahead, a slow-moving storm centered over the upper Midwest will drift eastward, reaching the northern Atlantic States by Thursday. Another widespread outbreak of severe thunderstorms can be expected later Tuesday, especially from Michigan to eastern Texas. On Wednesday, lingering strong thunderstorms may spread as far east as the upper Ohio Valley and the lower Great Lakes region. Additional rainfall associated with the storm could reach 1 to 3 inches, especially in the Mid-South, Northeast, and along the southern Atlantic Coast. Elsewhere, much cooler air will arrive in the Far West, but heat will build by week’s end on the High Plains.
The 6- to 10-day outlook calls for near- to above-normal temperatures nationwide, except for cooler-than-normal conditions in the Far West. Meanwhile, near- to below-normal precipitation across the majority of the U.S. will contrast with wetter-than-normal weather across the nation’s northern tier from the Pacific Northwest to the Great Lakes region.
