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.

The Mpemba effect is what this is called. One of my sons used this for a science fair experiment, but we proved unable to recreate it. Many late nights were spent with freezers and thermometers recording temperatures and taking photos. It was a bust. I figured that our results were just as meaningful as if we HAD observed the effect, but his teachers did not share that opinion.
It feels like it usually does when it's whatever temperature it is. The wind is variable in everyday life and part of being usual feeling at that temperature. It
s getting rid of the meaning of usual that constitutes clickbait.
The chief thing about temperature when it's cold is the temperature where your breath condenses and freezes on your nose hairs, which produces an odd feeling each breath as it freezes and thaws. That point is unaffected by wind.
Temperature and heat are different things. We perceive temperature on our exposed skin based upon the rate of negative heat flow. There is a formula for wind chill that equalizes the perceived rate of heat loss for exposed skin at temperature T with wind velocity zero , and at temperature t2 at wind velocity X. Temperature T is the wind chill temperature.
And yes, it's a weather ratings gimmick, but it still provides helpful information.
Albert Einstein famously postulated about thermodynamics: “It is the only physical theory of universal content, which I am convinced, that within the framework of applicability of its basic concepts will never be overthrown.” What he said.

The very idea of any prosecutor releasing a smear “report” on a defendant he was unable to convict, should be repugnant to any lawyer who believes in the integrity of our criminal justice system. Instead we have gloating trolls cheerleading such a disgusting abuse of process.

Multiple accounts that Smith is preparing a report and that Garland will release it publicly, all before the inauguration.

Musk and Ramalama apparently recommend ending Liz Warren’s Consumer Financial Protection Bureau. It is funded outside the regular appropriation budget with money direct from the federal reserve and with pirate’s booty from fines. It was intended by Democrats to be their political pit bull operating outside economic and legal accountability, unable to be stopped by budget measures just like wars. Lefties are arguing the wealthiest man on the planet wants to get rid of it only because it will help make him more money. Expect to see this Fox Butterfield effect for every dollar and department those two want to cut. Every phonet baloney Washington job is sacred…
