But the flip of the calendar to the New Year will bring a dramatic change in the weather pattern.
Highs on Sunday will be in the low to mid-40s, but an arctic front will begin to move into Fairfield County by the evening, causing temperatures to plummet with a wind-chill factor near zero overnight.
The frigid temps are expected to continue through Wednesday morning, according to the National Weather Service.
There could be snow showers and flurries at times, but overall, mostly sunny skies are expected.
Sunday's overnight low will fall to 23 to 25 degrees.
The high temperature Monday will reach 28 to 30 degrees with an overnight low in the single-digits to 10 degrees.
Tuesday's high will be even colder, with highs in the upper 20s and the overnight low once again in the single digits.
It will warm up a bit Wednesday with a high temperature in the mid-30s expected.
