There is a Slight Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PARTS OF THE MID ATLANTIC...NORTHERN NORTH DAKOTA...AND WESTERN INTO NORTHERN TEXAS SUMMARY Scattered wind damage remains possible with thunderstorms across the Mid-Atlantic through the remainder of the afternoon and evening. Large hail and damaging gusts may still occur with thunderstorms in North Dakota and west/northwest Texas. 20Z Update The previous forecast (see below) remains generally on track. A mesovortex embedded within a multicellular complex developed a few hours ago and produced a localized swath of intense winds along the OH/PA border. A repeat of such activity cannot be ruled out across western into central PA given the presence of a broad baroclinic boundary for ongoing storms to traverse. However, confidence in the development of another mesovortex is too low for an appreciable modification of severe probabilities at this time.
