Our heat wave continues across much of southern New England as we have more 90 degree days in the forecast. Boston hit 91 degrees on Sunday so today marks day two of the heat wave, while Hartford is on day three.
Highs reach the low 90s across interior southern New England with heat index numbers in the mid to upper 90s. Cape Cod, the south coast and northern New England will have highs in the 80s with heat index numbers around 90. With the hot and humid airmass in place, a pop up storm or shower is possible all day until sunset.

We have a similar forecast on Tuesday with more heat and humidity. Highs will be a few degrees hotter, in the low to mid 90s. Humidity will also be higher, so it will feel like near 100. Pop up storms are possible again in the heat of the afternoon.
Wednesday is our transition day, although we keep the heat and humidity around with highs again in the low 90s. A cold front heads into northern New England by morning, with southern New England getting the rain by afternoon and evening. The storms and showers head through by evening.
The frontal boundary stalls just offshore to our south for Thursday so we can't get the clouds or rain chances completely out of southern New England. Farther north it will be pleasant with highs in the 80s and low humidity.
Friday is the pick of the week with highs in the upper 70s to low 80s and an onshore wind thanks to a high pressure system settling in. Humidity will be low and there's plenty of sunshine forecast.
This weekend will be cool as well with highs around 80 both days, but the forecast models have different solutions by Sunday into next week with a stalled front and weak coastal low. For now, we have highs in the low 80s and more clouds, with limited rain chances by the end of the 10-day.
