If you are feeling a little deja-vu, the timing of this heat is very similar to that boiling heatwave we had a few weeks ago. That one also started on a Sunday and now, once again, many areas will reach an official heatwave this week (Sunday-Tuesday).

Add in some very “juicy” dewpoints and it will feel close to 100 degrees at times Tuesday afternoon.
As for the storm threat…
SPC has placed parts of southern New England in a “marginal” risk for severe weather.

Tuesday’s threat is partial due to an approaching cold front and also may be influenced by the departing remnants of Tropical Storm Chantal.
As is typical, we will have to watch the skies from mid-afternoon through the evening on Tuesday.
Any storms that do develop could contain some very heavy downpours, frequent lightning and some pockets of wind damage.

Temperatures will tumble on Wednesday and remain largely in the 70s of the remainder of the week.
Each day will feature a mix of sun and clouds as well as a threat for some scattered showers.
