Overview: As a cold front collides with our hot, juicy and unstable atmosphere, thunderstorms may explode onto the scene this afternoon. As such a severe thunderstorm watch covers the region through 10 p.m. tonight. Hail to two inches in diameter and damaging winds to 70 mph are possible with storms that develop. Storm coverage may be greatest in the northern parts of the region - but storms are possible anywhere. Severe thunderstorm and tornado watches extend all the way up the East Coast to southeast Maine.
