A mild pattern across much of the country will continue for the remainder of the week. During the next few days, colder air will graze the Midwest and Northeast, but temperatures will rise to near-record levels across the nation’s midsection. In fact, mid-week temperatures should reach 60°F as far north as Montana, with readings topping 70°F as far north as the central High Plains. Late in the week, modestly cooler weather will arrive in the West.
