Original post: CONNECTICUT — A severe thunderstorm watch is in effect until 7 p.m. Sunday for the entire state of Connecticut.

The National Weather Service said wind gusts up to 75 mph are possible, along with hail and frequent lightning.

“After a mainly benign and muggy morning, things dramatically change this PM,” said WFSB 3 TV meteorologists. “An approaching cold front kicks off a couple rounds of rain and storms. Be ready between 1-10pm from northwest to southeast. Some storms in the afternoon and again early this evening will likely be strong to severe, and that’s why we have declared it a FIRST ALERT WEATHER DAY. The greatest impact will likely be frequent lightning, followed by downpours and strong and damaging wind gusts. Large hail is possible if we get a few supercells to develop, and even an isolated tornado is possible, but not the primary threat. Prepare for possible tree damage, power outages, etc. We’re now in the level 3 of 5 risk category for receiving severe wind producing storms! Take this seriously folks!
