Heat Advisory Issued As Strong-To-Severe Thunderstorms Forecast In Hartford/Tolland County

HARTFORD/TOLLAND COUNTY, CT — A heat advisory has already been issued from 11 a.m. until 8 p.m. on Thursday.

The National Weather Service said heat index values around 100 expected.

Besides the heat, there is a chance for more rain today and then a chance of more thunderstorms and rain on Thursday afternoon and evening, according to the weather service.

"Storms will be possible in the afternoon and early evening hours as a cold front approaches from the west (they could be strong to severe). Lightning, heavy rain, damaging wind gusts, and hail will be the top threats, though an isolated tornado can’t be ruled out. The main round is expected from west to east between 4pm-10pm," WFSB 3 TV meteorologists said.
