Tonight, an arctic cold front will sweep through the state and potentially bring some snow squalls along with it.
Winds will get stronger overnight, and while temperatures will be in the 20s and 30s Wednesday night, it'll feel much colder by morning.
Chief Meteorologist Bruce DePrest said temperatures will range from 15 to 20 degrees when we wake up, but wind chills will range from 0 to 10+.
Ahead of this dangerously cold weather, Eyewitness News declared an Early Warning Weather Day. The National Weather Service also issued a Wind Advisory for all of southern Connecticut from 9 a.m. through 6 p.m., and a High Wind Watch was issued for the entire state from Thursday afternoon through late Thursday night.
This is all part of the same cold air that's been freezing the Midwest.
As for a highs on Thursday, they'll range from the upper teens in the Litchfield Hills to the low and mid-20s elsewhere.
"Winds will gust to 30-40 mph with gusts up to 50 mph possible. There is a chance for a snow shower or snow squall with the cold air moving in," DePrest said.
Most of the day will feature a mix of sun and clouds.
The weather will get dangerously cold as the core of the arctic air moves into the area on Thursday night.
DePrest said there could be potentially damaging winds, and dangerous wind chills.
"Winds could guts to between 50 and 65 mph and power outages are likely. If you have any outdoor inflatable Christmas decorations, you may want to keep them deflated or bring them indoors," DePrest said.
He said the air temperature will drop to between -5 degrees and 10 above by late Thursday night, "but wind chills will plummet to between 10 below and 25 below zero."
Friday is also expected to be bitterly cold with temperatures expected to stay in the teens or low-20s.
"Despite abundant sunshine, temperatures will only reach the teens in many parts of the state, perhaps the lower 20s if we’re lucky," DePrest said.
The wind will die down by Friday night, but temperatures will drop into the single digits for parts of the state.
"Temperatures will drop to between 5 and 15 degrees. However, clouds will overspread the state by midnight and that will keep temperatures from getting any colder," DePrest said.
AAA sought to remind drivers to keep up with their vehicles so they don't get stranded in the cold. For a list of cold weather driving tips, head here.
The auto club also pointed out that cats like to shelter under vehicles to stay warm. It urged people to tap their hoods or honk their horns before starting the vehicle.

The arctic air departs just in time for storm system to envelop the state by way of the Great Lakes.
Snow is expected to develop in the pre-dawn hours on Saturday, and it will accumulate.
The state could see between 1 and 6 inches, but the snow will change to a wintry mix in the morning, then rain by mid-day across much of the state.
Temps will rise into the 30s for interior Connecticut and the 40s along the shoreline.
Sunday will start out wet with rain likely in the morning. Temperatures will be in the 40s and 50s.
