Published 6:29 am, Friday, May 31, 2013
Already? A "triple-H" day -- hazy, hot and humid -- so common during August is on tap for this "spring" day in southwestern Connecticut.
The heat and humidity, in fact, are expected to be so onerous that the state has issued an air-quality alert from 11 a.m. to 11 p.m. today, warning that unhealthy ozone levels are possible.
Today's daytime high temperature will rise to about 90 degrees, according to the weather service, with a southwest 6 to 11 mph.
Tonight will be mostly clear, with a low temperature in the mid-60s and a southwest wind 3 to 8 mph.
Tomorrow also should be sunny but not quite as hot, with a high temperature in the low-80s. Nighttime will be mostly cloudy, with a low temperature in the mid-60s.
On Sunday, the NWS says there is a 20 percent chance of showers and thunderstorms after noon. Otherwise, skies will be partly sunny and the temperature will rise to a high in the upper-70s.
There is a greater chance of showers and thunderstorms Sunday night, with a low temperature in the low-60s. Odds of precipitation are about 60 percent.
On Monday, showers are likely as clouds prevail throughout the day, as the temperature rises to the mid-70s. Chance of daytime precipitation is 60 percent. There remains a 30 percent chance of showers at night, as the temperature dips to a low in the upper-50s.
The outlook for Tuesday, according to the weather service, is sunny and temperatures in the 70s.
