Isolated to scattered strong to severe storms are possible from the Carolinas to the Northeast on Tuesday afternoon/evening. ...Synopsis... A mid-level trough will shift east from the Great Lakes to the Northeast on Tuesday. Moderate mid-level flow will overspread much of the Great Lakes and Northeast. At the surface, a cold front will move east across the Northeast and arc back into the southern Plains. This front will be the primary focus for severe thunderstorm potential on Tuesday. ...Carolinas to the Northeast... Low to mid 70s dewpoints should be in place ahead of the cold front east of the Appalachians on Tuesday. Diurnal destabilization should result in weak to moderate instability from the Carolinas into the Northeast by early afternoon. The greatest instability is expected across North Carolina and Virginia. Storm coverage will likely be higher in this area, but with limited deep-layer shear, storms will likely be less organized. Farther north, stronger shear will be present from Pennsylvania northward. This may result in greater storms organization including the potential for a few supercells with a threat for large hail and damaging wind gusts. Mid-level lapse rates will be weak (<6 C/km) which will be the primary limiting factor to greater severe weather probabilities across portions of the Northeast. ..Bentley.. 06/29/2025 $$
