Thunder, Showers Accompanying Cold Front Today

A cold front will break through Thursday's warm temperatures, bringing with it showers and thunder. Temperatures are expected to be in the 70s and 80s today, but things will change quickly in the mid-afternoon.

"An approaching cold front will trigger brief scattered showers and perhaps a few thunderstorms with gusty winds between 3 and 8 PM" across Southern New England, the National Weather Service said.

The rain should begin subsiding by the late evening. Friday morning is expected to be sunny.

The first weekend of fall will be another pleasant one, with temperatures in the 70s and 80s and mostly clear skies. It's a trend you can expect into October.

"Temperatures are likely to remain above average for the balance of September and into early October," AccuWeather Senior Meteorologist Dave Dombek said.
