Severe Thunderstorms Predicted Monday in Boston

Have outdoor plans today? If so, keep an eye to the sky.

The National Weather Service has issued a severe thunderstorm watch for most of Massachusetts. The Cape and Islands are not in the watch area.

A weak cold front is expected to approach Monday afternoon allowing for scattered showers and thunderstorms to develop.

"This cool front is a slow mover up in northern New England right now," WHDH meteorologist Jeremy Reiner said on his blog. "This slow moving front will settle into our part of the world very late this afternoon bringing a chance of some scattered t-storms."

The NWS says a few of the storms will become strong to severe, with large hail, damaging wind gusts and cloud-to-ground lightning.

Heavy rainfall is also expected in these storms, resulting in some localized flooding. Parts of Middlesex and Norfolk counties are already in a flood warning.

The threat of these storms is from 2-10 p.m.

A severe thunderstorm watch means conditions are favorable for severe storms to develop.
