One more day of the 90-degree heat is in store for most of southern New England. It won’t be as hot as Tuesday, but temperatures will still reach into the 90s. The exceptions will be Cape Cod, the Islands and the North Shore areas along the coastline.
It’s certainly been uncomfortable the past few days, and while cooler at night, it hasn’t been cool. We tied the warmest low temperature of 72 degrees on Tuesday which had been set back in 1999. Of course, overall, the nights are warmer in Boston now than 100 years ago due to the heat island effect, which traps the heat during the day.
It will be another warm night tonight before a cold front slowly pushes the core of the heat out to sea. This front will bring a period of showers and perhaps thunderstorms to western New England tonight and tomorrow morning. However, it's likely eastern areas will need to wait until late Thursday night and early Friday to see appreciable rainfall.
The torrential rain could fall at times, and street flooding is possible with this system. There is a chance the evening commute Thursday is impacted, but a higher likelihood the morning commute Friday occurs with some heavy rain for certain areas.
Saturday should be the best day of the weekend with lots of sunshine and cooler and drier conditions. It will be more typical for how you likely think of September.
Another weather system brings back the clouds and a renewed chance of rain Sunday afternoon or night, with a chance of rain continuing into Monday. Warm and dry weather is returning thereafter.
Today: Sunny, highs in the lower 90s, though cooler on the Cape and north shore coastal areas.
Tonight: Mainly cloudy and muggy. Lows 65-70.
Thursday: Warm and muggy. Highs 75-80. Some showers possible with heavy downpours.
Friday: Showers likely, during the morning and then cloudy and cooler. Highs 72-75.
Saturday: Mostly sunny, with a high near 75.
Sunday: Becoming cloudy and seasonable. Highs in the low to mid 70s. Chance of some rain.
