A cold front slicing through stifling heat and humidity will give way to vicious thunderstorms this afternoon and evening.

Targeted cities include Boston, Providence, Hartford, New York, Philadelphia, Baltimore, Washington D.C., Pittsburgh and Cleveland.

On Tuesday, powerful thunderstorms erupted from this same front. Across northern New York, Vermont and New Hampshire, there were dozens of reports of downed trees and large hail.

This afternoon, the thunderstorms will explode farther south across the megalopolis.

Read about the impacts these storms have had so far along the Northeast and eastern coast.

The main threats from these beastly storms will be damaging blasts of wind, hail larger than the size of quarters, dangerous, vivid lightning and blinding downpours.

If you have outdoor plans this afternoon and evening, pay close attention to the weather. Keep an eye to the sky and heed any watches or warnings that may be issued.

If a watch is issued, this means the potential for a dangerous thunderstorm is high, but the threat is not imminent. If a warning is issued, this means a dangerous thunderstorm is imminent, and you should take shelter immediately.
