Supercells with Hail, Winds and Tornado Risk Fire Up Over Eastern New York — SevereWX

Developing Severe Threat in the Northeast

Afternoon heating is destabilizing the atmosphere across portions of central into eastern New York and southern Vermont, setting the stage for a round of severe thunderstorms. The Storm Prediction Center (SPC) has issued Mesoscale Discussion 0463, highlighting rapidly growing cumulus fields beneath a cirrus shield as a mid-level trough approaches from the Great Lakes.

Forecast soundings show surface temps nearing 80°F with dewpoints above 60°F, fueling around 1000 J/kg of MLCAPE. Steep mid-level lapse rates near 7°C/km combined with over 50 knots of effective shear favor organized storms, including supercells and multicells. Primary concerns include severe wind gusts of 55-70 mph and hail up to 1.75 inches, with a couple of tornadoes (up to 95 mph peak intensity) not out of the question.

The MD is valid until around 3 PM EDT, and SPC notes a 60% chance of issuing a watch within the next couple of hours. WFOs in BTV, ALY, BGM, and BUF are notified to monitor trends closely.

This setup marks a shift eastward from recent Plains and Midwest action, bringing uncommon severe potential to the Empire State. Keep an eye on radar as initiation looks imminent.

Stay Prepared: Have multiple alert sources ready, know your safe spot, and monitor updates from local NWS offices. Severe weather can change quickly—don't wait for warnings to act.
