Scattered severe thunderstorms will be possible Monday across portions of the Northeast and mid-Atlantic states. Damaging gusts will be the primary severe hazard. ...Synopsis... Broadly cyclonic mid-level flow will exist across the northern CONUS Monday as an upper-level anticyclone remains established across the south-central U.S. A cold front will move east off of the northeast U.S. coast late Monday and extend west from the mid-Atlantic across the TN Valley and central Plains. ...Mid-Atlantic/northeast U.S... A very moist air mass will exist in advance of the cold front Monday characterized by surface dew points in the 70s and PW values near 2 inches. Southwest to west mid-level flow will result in deep-layer shear averaging 25-30 kts over the Delmarva Peninsula and around 40 kts across the northeast.
