“Pop-up” showers and thunderstorms have formed across eastern Chester County in SE PA and across northern Delaware and the areal extent of this rainfall should expand during the next few hours as a slow-moving cold front heads our way. The cold front has some upper level support to work with as we progress through the afternoon and evening hours along with a sultry air mass containing plenty of moisture to be "squeezed out". The threat for showers and thunderstorms will continue through the night and there can be localized downpours associated with any shower or thunderstorm.
