    While temperatures were cool in the East and the West Saturday, things will heat up to start off the new week.

    On Saturday, the hot zone will be in the center of the country, with over 100-degree temperatures from Nebraska to southern Texas.

    Starting on Sunday, the heat will migrate to the West and East coasts.

    As showers and storms quiet the heat in the Plains on Sunday, temperatures will be on the rise in the West. Cities like Salt Lake City and Boise will be in the lower 90s, about average for this time of year.

    However, high pressure from over the Pacific will move closer to the area by Tuesday. This and a northward moving jet will bring cities in the interior Northwest closer to 100 degrees for the afternoon highs.

    Temperatures will also be rising in the East for the start of the week. With a pleasant start to the weekend in the mid-Atlantic, temperatures were in the upper 70s to mid 80s on Saturday.

    As thunderstorms start to become more spotty on Sunday and Monday, more cities will reach or surpass 90. These hot cities for the start of the workweek include Philadelphia, New York City, Boston and Washington, D.C.

    This heat is expected to continue through mid-week bringing the chance for a heat wave in many urban areas.

    Through Tuesday, the 90-degree heat will expand farther through the Ohio and Tennessee valleys, even into portions of the Southeast.
