I didn't venture out. That's a photo by Meade.

Rather bleak looking considering three more weeks of autumn left to run.

Wind chill is clickbait. It feels like what the actual temperature is, not something else. If it's 20 degrees out and there's a howling 40 mph wind, what is the temperature of a metal flagpole standing in the wind? 20 degrees.
Wind chill and heat index are inventions to pump TV weather report ratings and make everything seem to be a record.

“And I think overall, just outside of the press corps, the country itself was feeling burnt out“
…and if the new administration is smart they will maintain that energy, moving faster than the propaganda, too fast for the narrative makers to keep up…
Regardless of whatever they are, I find 20 degrees with no wind to be way more preferable to 20 degrees with a 40 mph wind.
But that's just me.
I believe the thermal conductivity of moving air is greater than that of still air, and the difference increases with air speed. Regardless whether the concept of wind-chill is also clickbait.
I learned this week about the concept of wet-bulb temperature. A cousin to wind-chill. Alway new things to know.
In cold weather, wet hands are limited to lowering the temperature to 32 degrees, at least until the water freezes. For a real experience, try spilling gasoline on your hands. Then they evaporate to minus 40 degrees in a wind, where gasoline freezes. A common experience of pilots putting gas in their own airplanes in the wind.
Your body has a layer of warmer air around it, a coat helps by retaining the layer. Wind dilutes and dissipates this layer with cold air. In industrial drying processes the drying rate, or heat transfer to the product, is approx proportional to the 0.75 power of the air velocity. So the flagpole temp is not affected by wind, unless you warm it up before your measurement. It would then drift down to ambient temp. Ice still freezes at 32 degf even in the wind. It may freeze faster in the wind, or perhaps not. There are studies that hot water freezes faster than cold water, in some cases, weird science.
