Good afternoon everyone, 

We're still finalizing the forecast but we did want to send a short update to the briefing sent this morning to discuss our current thinking. Expect a full briefing with updated graphics to be sent by 5 PM today.

We are not anticipating any significant changes to the heat and humidity forecast for the weekend to what was briefed this morning.

The first occurrence of true mid-summer heat and humidity arrives Saturday and continues into Sunday. Heat Advisories remain in effect for areas away from the coastlines and away from the Berkshires. Air temperatures in the 90s with heat indices between 95 and 102 degrees. 

Confidence in the heat forecast is high. 

Widely scattered strong to severe thunderstorms are possible Sunday afternoon, especially across northern & western CT into western & central MA. Localized straight line wind damage and hail would be the greatest risks in any strong to severe storms which develop. 

Attached is the Severe Thunderstorm Outlook for Sunday from the Storm Prediction Center. 

Confidence in the thunderstorm forecast is moderate. The overall coverage of thunderstorms is the largest question mark. 

Thank You! 

Meteorologists: Andrew Loconto and Kevin Cadima
