Extreme temperature change records?

[Jason Bolt]

The thread about the record cold got me thinking: Does NCDC or anyone else keep track of extreme temperature change records? I couldn't find any, but if the forecast verifies Nowata, OK will go from -31 on Thursday 2/10/11 to +71 on Thursday 2/17/11 for a one week temperature change of 102 degrees. That just blows my mind and has got to be some kind of a record.

Chinook winds in Colorado and Wyoming produce extreme variations, 60°+, in a few hours at times.

Heat bursts have also been known to greatly increase temperatures in just seconds. I am not sure off the top of my head of how much, but I am sure if you were looking at a degree per time period they would rate as one of the highest.

I've seen that happen at my own house; I live on the north end of Colorado Springs where there's quite a bit of hills. I've seen it go from -15F at about 1 am to 40 degrees when I woke up!

Check this out! 49 degree temp change in 2 minutes.

There's another good one for extreme temp drop.

I was just thinking the same thing... We went from +75 to -3 (with a wind chill of -40) in 2 days right before the blizzard (which we got absolutely nothing out of). Then this week our low last night was -11, and we are forecast to be in the 70's again on Monday!

It's currently 42 right now in Nowata - That's a change of over 70 degrees in about 36 hours.

Heat bursts from dying thunderstorms frequently cause very significant temperature changes over very short time periods (on the order of minutes). I see such instances featured on various days in the Weather Guide calendar every year.

I read about some temp change in the Dakotas dont have a date or exact location but I remember it saying that temps were below freezing and the temps rose greatly later that day making it a record temperature change due to a warm front. Funny I was just thinking about this very topic on my way home from work the other night.

This coming Tuesday, check out Charlie Wilson's "Center of Circulation" show on www.ipr365.com. Dude is crazy good with stats and such like these. You might also see his examiner.com (Weather History column) he puts out, might have touched on the records. If I remember right, Montana held/holds the record. Something like 80 degress in less than 24 hours. It might even be the Chinook deal that Mike Smith touched on.
