Forty-five balmy degrees this morning

[Chi-Town]

Happy to be here. Coldest temperatures in the Chicago area in a generation.

All the temperature readings in Minnesota according to the Weather Channel have -50 or lower wind chills going on.

I do remember going out for a short time in that kind of weather in Minneapolis around November of 1991. Did not stay out very long.

I wish they would change the wind chill reading to something people can understand. I think a wind chill is not the actual temperature, but what the temperature "feels" like, based on the wind. This is very confusing.

A meteorologist technical term to add emphasis how cold it is. I look at life in whole numbers VS decimal parts. Wind chill is a decimal measure to me.

When it is minus something or another it adds little or no value to know it is more minus with the wind.

Similarly for the summer temperatures and the "feel like" temperature.....

Keep it simple....the actual temperature is just fine!

Winter in Florida.

In a nutshell, 'windchill equivalency' is simply a comparative measurement...on the rate of heat loss.

In other words, if something (human body/car engine/etc.) starts out warmer than the ambient temperature, it will lose heat at an accelerated rate in a wind...that is equal to a colder ambient temperature with no wind.

Inanimate (or even animate) objects will NEVER get colder than the ambient temperature...regardless if the wind is blowing 100 mph.

Self-explanatory.

I understand, but why assign a number to it that no one understands? A lot of people watch the weather report and think the numbers reported are the temperature, when they are really the wind chill factor. This creates a lot of misinformation. Also, with respect to the human body, isn't the rate of body temperature change more dependent on how much clothing you are wearing, or whether you are in the sun or in the shade?

I'm sure some do it to make the temp's more 'dramatic,' but there is also a legitimate reason for doing so.

That being it warns folks to dress for a much colder ambient temp...so they can minimize heat loss.

Shade/sun doesn't make all that much of a difference (given that there isn't much 'heat' in the sun at this time of the year anyway), but dressing with wind resistant clothing, covering all exposed skin or even staying out of the wind entirely if possible...makes a big difference.

I've worked in some seriously extreme cold and one older guy I knew would wear his rain bibs/coat...when the wind was blowing.

Yeah, it looked a little silly, but he knew that was the best way to eliminate the wind...from sucking heat from his body.

Remember, the chart (which has actually been tweaked over the years) was developed simply to provide a 'rough equivalency'...in regards to heat loss.

At 2am this morning when I left the garage my car said -7. Not so bad. Once I got out of my car, with heated seats, and steering wheel, I walked 50ft to the door of the gym, bundled up in my best Columbia coat, boots, hat.
Soon as the wind hit me the -37 windchill made total sense to me.

Perfect example! :thumbup:

When working outside at a relatively balmy 10 below, I would dress a lot differently if it were calm...than if a 25-30mph wind was predicted.

Deadly Cold & Near records (click here) (http://www.yahoo.com/gma/brutal-bone-chilling-cold-moving-midwest-northeast-115403591--abc-news-topstories.html)

At least 8 dead as dangerous cold paralyzes Midwest, frigid temperatures soon to target Northeast.

Chicago is forecast to reach an actual temperature of minus 26 degrees Wednesday night -- just one degree away from the city's all-time coldest temperature, which was set in 1994.

And soon, freezing temperatures will take over the Northeast.

As the cold takes over and residents are urged to stay inside to avoid dangers including frostbite, the U.S. Postal Service has suspended delivery for Minnesota, western Wisconsin, western Illinois and Iowa.

Over 1,700 flights have been canceled at Chicago's airports for the day, and Amtrak suspended all Wednesday trains to and from Chicago.

And let me add... wind chill is a relation no how quickly something will loose heat. An object (like a car, or other inanimate object or something that does not generate heat) will only cool down the the ACTUAL Temperature. It will not get any colder.

Again, wind chill only lets one realize how quickly something warm will cool down the the ambient temperature.

I just left my work site, and came home where it was 60 degrees warmer at home. Ambiant temp at my work location was -25F, home it was 35F.
