Supercells Charge East into New England with Hail, Gusts, Tornado Risk — SevereWX

Storms bubbling up over the Adirondacks are pushing east into northern and central New England, where they could organize into splitting supercells packing a punch this afternoon.

A shortwave trough along the St. Lawrence Valley is teaming up with a destabilizing air mass ahead of a frontal boundary. Cloud breaks east of the Champlain Valley are boosting instability, with MLCAPE climbing to around 1000 J/kg along a subtle warm front lifting through Vermont and New Hampshire. Early thunderstorms are already firing, and more development is likely along terrain or the front.

Shear is ramping up through the afternoon, supporting supercell modes despite mostly unidirectional winds. Expect large hail up to 1.25 inches, gusts of 55-70 mph, and low-end tornado potential—up to 90 mph winds—if storms interact with the warm front.

The setup covers parts of Maine, New Hampshire, Massachusetts, Vermont, and eastern New York. SPC is eyeing this closely with a 60% chance of a Severe Thunderstorm Watch through around 3 PM EDT.

Key Hazards:

Residents in the region should monitor radar closely, have severe weather apps ready, and know your safe spot indoors away from windows. Stay weather-aware this afternoon.
