Darien forecast: A summer place
The second day of summer today will be just as nice as the first -- with the same caveat: air quality will be less than stellar.
The combination of warm temperatures and rising humidity today has promoted an air-quality alert to be issued for southwestern Connecticut from 11 a.m. to 11 p.m. by the state Department of Energy and Environmental Protection.
Otherwise, the National Weather Service says skies will be sunny today as the temperature rises to a daytime high of about 80 degrees. There will be a south wind 6 to 11 mph.
Tonight, there may be patchy fog as the temperature dips to a low of about 60 degrees and a south wind 5 to 8 mph becoming calm after midnight.
Sunday, after patches of fog burn off in the morning, skies should be sunny, with a high temperature in the low-80s and a southwest wind 5 to 13 mph. Nighttime will be partly cloudy, with a low temperature in the upper-60s.
On Monday, there could be isolated showers and thunderstorms after 3 p.m., the NWS says. Otherwise, skies will be partly sunny, with a high temperature in the mid-80s. Chance of daytime precipitation is 20 percent.
Odds of scattered showers and thunderstorms increase slightly Monday night -- to 30 percent -- under cloudy skies. The low temperature is expected to be in the mid-60s.
The outlook for Tuesday, according to the weather service, possible scattered storms, partly sunny skies and temperatures in the 80s.
