beavis1729 Posted November 22, 2012 Author Share Posted November 22, 2012 beavis, I found a wind chill of -58F for ORD on 12/24/1983. Temp was -25F with wind of 25 mph Thanks Hoosier...good catch. Link to comment Share on other sites More sharing options...
beavis1729 Posted November 22, 2012 Author Share Posted November 22, 2012 February 1936 might also be worth checking. It was ridiculously cold especially in the northern Plains/upper Midwest. Yep...I'll take a look. So far, I've focused on more recent decades, as the hourly temperature and wind speed data is more readily available on Weather Underground.

Geos Posted November 22, 2012 Share Posted November 22, 2012 Morning of 01/30/96 north central Montana had lows as extreme -40°, even some unofficial locations approaching -50° near the Canadian border. Estimated wind chills on the new scale were pushing close to -75 - -80° with 15-20mph winds. Link to comment Share on other sites More sharing options...

I couldn't find any official wind chill readings lower than -50 in late January 1996...but I'll keep looking. In the meantime, there is always good old January 1982: Montana Glasgow, 1/6/1982: wind chill -55 (temp -35, wind 7 mph) http://www.wunderground.com/history/airport/KGGW/1982/1/6/DailyHistory.html?req_city=NA&req_state=NA&req_statename=NA Link to comment Share on other sites More sharing options...

I'll see if I can find it again. Hopefully I converted to the new scale correctly. - But there was mention of -90 wind chills in areas of the state that morning. Of course that would be on the old scale. Link to comment Share on other sites More sharing options...
Geos Posted November 27, 2012 Share Posted November 27, 2012 Cool...yeah, I'm trying to collect confirmed/documented readings on the new scale...so if there is documentation somewhere, that works! I still plan to look more in depth at the 1935-36 winter, which was brutal across the northern plains. Here it is: http://www.nytimes.com/1996/02/02/us/montana-journal-where-the-wind-chill-has-been-90.html Link to comment Share on other sites More sharing options...
Minnesota Meso Posted November 27, 2012 Share Posted November 27, 2012 February 1936 might also be worth checking. It was ridiculously cold especially in the northern Plains/upper Midwest. Although this isn't Feb '36 it is in Jan of that year. What is the coldest windchill ever seen in the Twin Cities or Minnesota? The answer can be a little tricky because on November 2001 the formula on how to calculate the windchill was changed. Perhaps the coldest windchill the Twin Cities has ever seen was -67 degrees F with the new formula (-87 degrees F with the old formula) back on January 22nd 1936. The temperature was -34 degrees F with a wind speed of 20mph. All traffic in the Twin Cities was severely hampered and a number of fatalities were caused by the cold. Without a lengthy state-wide wind record, it is difficult to say when was the coldest statewide windchill. There are some candidate dates though besides January 22, 1936. On January 9th and 10th, 1982 temperatures of -30 degrees F and winds of around 40mph were reported in Northern Minnesota. This would translate to -71 degrees F by the new formula (-100 degrees F by the old formula.)

That was Christmas Eve 1983 in Emporia, Kansas but he was out in a more open area and probably colder than in town. I think on the new WC scale it would be like -50F to -53F. I tend to think it may be somewhere in the low to mid -50s but I could be wrong. Link to comment Share on other sites More sharing options...

blackjack123 Posted April 9, 2018 Share Posted April 9, 2018 On February 5, 1982 at 6:43 am there is an unknown temperature with a wind speed of 16.1 mph. So depending on whether the temp was -22F or -23F it would make the WC -48F or -50F. Most Kansas offices have no good records but Goodland has some really good records. https://www.wunderground.com/history/airport/KGLD/1982/2/5/DailyHistory.html?req_city=&req_state=&req_statename=&reqdb.zip=&reqdb.magic=&reqdb.wmo= Link to comment Share on other sites More sharing options...

My dad told me he had a temperature of -19F wind winds blowing between 25 and 35 mph in Emporia back in 1983. However no records to confirm it. He had a wind chill of possibly -50F to -52F(-72F to -77F using old formula). Link to comment Share on other sites More sharing options...

Knightking2018 Posted May 31, 2018 Share Posted May 31, 2018 I was 4 when that happened. I do remember the 1989 cold snap when I was 9. Temperature around -22F with winds at least 10mph making the wind chill near -45F on todays scale. I lived in Kansas and I put my foot out the door to see what it felt like for about 15 seconds. It feels like pins and needles or razor blades going through your skin. Link to comment Share on other sites More sharing options...
Knightking2018 Posted May 31, 2018 Share Posted May 31, 2018 Mansfield, Ohio January 20, 1985. Temperature -22F and winds of 29 mph created a wind chill value of -55F at 8pm. On the old wind chill scale it was -80F. Quite impressive for Ohio. Link to comment Share on other sites More sharing options...

beavis1729 Posted June 1, 2018 Author Share Posted June 1, 2018 Thanks for the info and documentation, KK. Impressive numbers in Waterloo on Christmas Eve 1983. While the difference between -40 and -55 WCs may not be that noticeable, I think there is a huge difference between WCs in the -40s vs. the -20s. Most winters, we have a few days with wind chills in the -20s, which is generally tolerable. Once you hit a -40 WC, it's a different world. The last bitter air I experienced was 1/6/2014, when ORD hit -16...and IMBY it was -17 with 25 mph sustained winds, creating wind chills in the -40s. Temps stayed in the -10 to -15 range during much of the afternoon and evening, and there was a foot of snow on the ground. It looked like the arctic tundra. 1 Link to comment Share on other sites More sharing options...
Knightking2018 Posted June 2, 2018 Share Posted June 2, 2018 Another things that seem strange is Kansas and Missouri all time record low temps are -40F which both occurred on February 13, 1905 in Lebanon, Kansas and Warsaw, Missouri. That actually is colder than the all time record lows of Illinois(-36F), Indiana(-36F)and Ohio(-39F). Iowa is -47F which is colder but those 4 states especially Iowa and Illinois tend to get more brutal winds and colder temperatures more often than Kansas and Missouri.

The Kansas/Missouri records being colder is a little surprising, but there could be various reasons. Even could be some microclimate thing.

The low in Muncie was -24F and winds were between 22 and 29 mph. To be more conservative if you go with a temp of -24F with winds of 22 mph you get a wind chill of -55F. That would be a safe bet.
