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. Frontal convergence and diurnal heating will contribute to thunderstorm development along the front by afternoon, with multicell clusters or line segments capable of mainly damaging downburst winds. ..Bunting.. 07/23/2022 Read more CHECK UPDATE ZOOM GRAPHIC
