A stationary frontal boundary across the Southeast U.S. will linger for the next couple of days keeping showers and thunderstorms in the forecast through Saturday. Some of these storms may produce localized heavy rainfall. This boundary also extends west into parts of the Plains, where scattered showers and thunderstorms will continue in the vicinity of the front. Storms are expected to be most widespread across the central plains today and Friday as several upper-level disturbances traverse the region. These storms will also be capable of producing heavy rainfall. Another frontal system moving south into the northern plains and Upper Midwest will spread showers and thunderstorms across the northern Rockies, northern plains, and into the Midwest and Great Lakes today and Friday. The system will reach the Northeast by Friday afternoon and evening, bringing showers and thunderstorms with it. Behind the front, a much cooler and drier air mass will move in. Temperatures are forecast to be 5 to 15 degrees below average across much of the north central U.S. into Saturday. Elsewhere, monsoonal moisture will keep mainly diurnally driven showers and thunderstorms across the Four Corners region, the central/southern Rockies, as well as the Great Basin. Temperatures will be 5 to 15 degrees above average through Friday from the West Coast states to the northern Intermountain Region.
