A storm system currently centered over northern Texas will gradually drift northeastward, reaching the Great Lakes States by Wednesday. Storm-total precipitation amounts of 1 to 3 inches will be common from the Mississippi River to the East Coast, with totals in excess of 4 inches possible in parts of the Northeast. Meanwhile, snow will spread from the central Plains into the upper Midwest, while locally severe thunderstorms will sweep across the South.
Elsewhere, showery weather will be confined to the Northwest, while dry weather (and a slow warming trend) will cover areas from southern California into the south-central U.S.
Looking ahead, the 6- to 10-day outlook calls for near- to above-normal temperatures nearly nationwide, and above-normal precipitation across roughly the northern half of the U.S.
