A cold front will bring scattered to numerous showers and thunderstorms to much of the Eastern Seaboard today. The remnants of Tropical Storm Julia will also drift slowly northward toward coastal North Carolina, which will result in showers and thunderstorms as well. Some showers and thunderstorms may produce heavy rainfall from the Carolinas north across the East Coast States today into tonight. Drier air will move into most of the Mid-Atlantic and Northeast for Tuesday, while scattered showers and thunderstorms will persist across the Southeast. Farther west, a cold front will move across the Midwest and Upper Great Lakes today. Scattered showers and thunderstorms are forecast to accompany the front. Some storms could be severe, as outlined in the Day 1 Convective Outlook from the Storm Prediction Center. The frontal boundary will become stationary across the plains Tuesday into Wednesday with scattered showers and storms possible from the northern Rockies into the Midwest. Moisture will gradually be on the increase across the southwestern U.S. through the next couple days. Scattered showers and thunderstorms are expected each day as a result. Some of these storms could produce locally heavy rain. A building upper-level ridge of high pressure across the south central U.S. will keep temperatures generally above average across most of the central and eastern U.S. into midweek. High temperatures are expected to be 5 to 15 degrees above average. The one exception will be the Mid-Atlantic and Southeast U.S. coast, where areas of persistent clouds and precipitation will keep temperatures closer to seasonal averages.
