A geographically unique setup is forecast to take place today across parts of Northeast. The SPC has outlined an Enhanced Risk (level 3/5) for much of Vermont, New Hampshire, and Massachusetts, as well as southwest Maine and far eastern New York. As a shortwave trough approaches, discrete supercells should develop along a prefrontal trough, ahead of which a moist, unstable environment exists. Mid-level lapse rates will be on the weaker side, which could temper updraft strength to some degree, but strong low-level shear should foster an elevated tornado and damaging wind risk with any more robust discrete supercells.
