Wednesday's high temperature could tie or break the record of 94 for July 13.
Tuesday temperatures are expected to reach between 85 to 90 degrees with Heat Index values in the mid- to upper-90s.
The National Weather Service said temperatures will hit the 80s across Greater Boston Tuesday, signaling the start of a spate of weather that will become increasingly hotter and more humid as the week wears on.
Afternoon showers and thunderstorms will be possible starting by Friday. Instead, lots of heat and humidity is in the forecast this week. As it tracks east tomorrow, the wind will be calm, as it takes a more southwesterly component. High pressure will be east of New England by this point and the southwesterly flow will unlock the tropical heat and humidity from the South.
After a delightful Sunday of weather in the Garden State, the week gets going with another dry day on Monday, according to forecasters. Humidity levels remain high Wednesday. It should be comfortably warm, bright summer day.
To kick off the weekend, a nice pattern of weather shows highs in the upper 70s and 80s for Friday with skies partly to mostly sunny. The humidity, with highs in the 80s, will lead to scattered showers during the afternoon.
