Severe thunderstorm watch in effect until 8 pm

A severe thunderstorm watch has been issued for Mercer, Middlesex, Hunterdon and Somerset counties until 8 p.m. Monday night.

Damaging gusts - This is less of a widespread threat than the heavy rain, but any one location has a 30 percent chance of experiencing the effects of damaging wind, including downed limbs, trees and utility lines.

Tornadoes, hail the size of ping-pong balls and wind gusts of up to 70 miles per hour are possible. The mechanism here is localized, wet microbursts.

Storms may weaken as they approach the shore, but can still pack a punch with heavy rain and strong winds if the weakening is slow.

A watch means conditions are favorable for damaging thunderstorms in and around the watch area.

"Isolated tornadoes and locally large hail are also possible", according to the National Weather Service. Warm and very humid air is in place over the area.

It's then going to move east toward New York City and into CT between 6 and 8 p.m. With the increasing sunshine, our atmosphere is becoming increasingly more unstable. Commuters - by vehicle, train, bus or subway - are urged to give themselves more travel time and go slowly. This is shown in the graphic below, with a almost two-inch bull's eye over the greater D.C. -Baltimore region.

"The best opportunity for showers and storms on your Monday will be directly ahead of the cold front", Walls said. Winds will increase aloft through the afternoon, as a trough (disturbance) in the jet stream crosses the East Coast.

The warned storm was part of a bigger line of thunderstorms stretching from south of Fort Wayne, Ind., into central MI that was moving east.

A strong line of storms is pushing across Maryland.
