Good afternoon, No real changes to the expected heat index values Tuesday and Wednesday did extend the Heat Advisory to more of MA Wednesday. Relief from the heat and humidity is still on track for Thursday, Friday and Saturday, with a return to seasonable temperatures and much more comfortable humidity. We included the graphic of the Heat Advisory as well as the expected Heat Indices Tuesday and Wednesday. We also should mention there is the risk for mainly afternoon and evening scattered showers and thunderstorms Tuesday. The activity may be more widespread later Wednesday into Wednesday night as a cold front crosses the region. There also is the potential for scattered strong to severe thunderstorms during the afternoon and evening of both Tuesday and Wednesday.
