 The southern portion of the system overall will produce some showers and thunderstorms through the central Rockies into the four corners. Farther east through the Great Lakes into much of the southeast and continuing through the mid-Atlantic and most of New England, high pressure will hold sway over a good swath of the region. This will lead to a good amount of sunshine with highs in the north in the 70s and then warming into the mid-90s farther south.
