The National Weather Service has a Heat Advisory on the books for the entire region through 8pm Friday night.
Officials say the highs will be around the 90-degree mark - but the high humidity will make it feel like its more than 100 degrees.
We won't get much relief from the heat overnight as the humidity will remain with us and temps will be in the low 70s.
Most of the entire state and Connecticut are covered by the advisory with the exception of the Berkshires and Cape Cod.
You are advised to limit outdoor activity and to stay hydrated.
