Potent shortwave will be moving from the western Tennessee Valley/Ohio Valley region into the Northeast through the day Saturday along with some elevated mixed-layer air. While surface temperatures will be rather cool, the presence of very steep mid-level lapse rates (>7 C/KM) will contribute to MUCAPE values potentially exceeding 1,000 J/KG to go along with strong mid-level shear. While the surface will be rather stable, just above the inversion parcels will be freely able to rise and rise vigorously thanks to the steep lapse rates. Scattered showers and thunderstorms (including potential for multiple short-line segments) are likely to develop through the afternoon and evening. More robust updrafts will be capable of producing large hail.
SEVERE SEASON IS HERE!!!!!!!!!
