In the summer, we say it is not the temperature, but the humidity, that makes it feel so hot and steamy. We measure both by using the heat index as a parameter of how it actually feels to your exposed skin when you step outside.
When a big winter storm roars in like the one today, it is the wind chill which makes it feel so bitterly cold to venture outdoors.

I've attached the wind chill chart, so you can see just how cold it actually feels when you factor both the temperature and wind speeds.
As of this afternoon, our wind chill values are in the teens. This results from temperatures near 30 and winds sustained at 20 mph.
Overnight, winds may be reduced to 10 to 15 mph. However, with lows dropping into the upper teens and low 20's, that will give us wind chill values in the single digits.
Please bundle up and make sure you cover any exposed skin if you are going to be outside for any length of time the next few days.
