There is a chance of early-morning showers and thunderstorms in southwestern Connecticut, before the temperatures spike to the upper-90s later today.

Skies will clear this afternoon, the National Weather Service says, as the daytime high temperature rises to near-record levels. There will be a west wind between 8 and 11 mph.

There is also an "air-quality alert" in effect for the region from 10 a.m. to 10 p.m., since the heat and humidity are expected to produce unhealthy ozone levels.

Tonight will be mostly clear with the temperature dipping to the upper-60s with a west wind between 4 and 7 mph.

Tomorrow is expected to be sunny and hot, with a high temperature in the low-90s. There is a chance of showers and thunderstorms tomorrow night, as skies become partly cloudy and the low temperature is in the upper-60s.

On Sunday, there is a slight chance of showers and thunderstorms through afternoon. Otherwise, skies will be sunny and temperatures will rise to a high in the upper-80s. Skies on Sunday night will be partly cloudy with a low around 70 degrees.

The outlook for Monday, the weather service says, is mostly sunny and temperatures in the mid-80s.
