Good Afternoon Everyone, We are becoming more confident in the potential for hot and humid weather Saturday through Tuesday. Right now Sunday and Monday appear to be the hottest days. Heat Advisories will likely be needed for heat indices between 95 and 100 degrees, especially in the Connecticut Valley and from the Merrimack Valley to the western suburbs of Boston. Temperatures at night will be in the 70s but may not drop below 80 degrees in the larger urban centers. We have attached the latest Heat Index forecasts for Saturday through Tuesday. If you have any questions or would like more information, don't hesitate to contact us via this email address, on NWSChat <https://nwschat.weather.gov/>, or by phone at 508.622.3280.
