Darien forecast: Summer makes a scorching debut
Summer starts today in dramatic fashion with what could be record-high temperatures across southwestern Connecticut, the National Weather Service warns.
In issuing both a "heat advisory" and "air quality alert" for today, the NWS says the daytime high temperature will soar into the mid- to upper-90s under mostly sunny skies. Factoring in the humidity, the heat index in the region will feel as though the temperature is at least 100 degrees or more.
More scorching weather is in store for tomorrow as well, as the heat advisory remains in effect through 8 p.m. tomorrow.
The air quality alert means that the hot, heavy air mass settling over the region for the next two days will produce unhealthy ozone levels from 11 a.m. to 11 p.m.
Tonight should be mostly clear with the temperature dipping to the low-70s, and a west wind between 3 and 6 mph.
Tomorrow, the heat wave continues, the NWS predicts, with temperatures rising again to the upper-90s in more sunny conditions. Tomorrow night there is a slight chance of showers and thunderstorms between 11 p.m. and 2 a.m. Friday. The temperature is expected to register a low in the mid-70s.
On Friday, there is a chance of showers and thunderstorms after noon. Skies will be partly sunny, with a high temperature near 90. There is a chance of showers and thunderstorms, mainly before midnight, and temperatures will decline to the upper-60s.
The outlook for Saturday, according to the weather service, is mostly sunny and temperatures in the mid-80s.
