A severe thunderstorm watch was issued for Hartford, Tolland and Windham counties until 8 p.m. on Monday.
Severe thunderstorm warnings were issued for parts of Hartford and Tolland counties until 7:15 p.m.
Chief Meteorologist Bruce Deprest said the reason for the volatile weather in southern New England recently is because of high humidity and high levels of "shear" in the atmosphere.
The National Weather Service confirmed an EF-0 tornado touched down in Wolcott on Sunday, and another tornado struck Revere, MA, on Monday morning.
Deprest said storms are expected to fire up on Monday evening as a cold front moves through the state.
Some thunderstorms could produce damaging winds, large hail, heavy downpours and frequent lightning.
"Some towns could get hit pretty hard, while many locations remain untouched," Deprest said.
After the cold front passes though, the state can expect drier air to come through Monday night.
Temperatures are expected to drop to the 50s and lower 60s by Tuesday morning, and the humidity is expected to drop as well.
There will be more comfortable weather in the next few days, however Deprest said "we can't rule out a few pop-up afternoon showers at some point over the next several days since the atmosphere aloft will be cool and just a bit unstable."
