weather change story

January 23, 2013

first off..no one needs to discuss global climate shift/change here..... we have talked about that and the horse has left for the dog food factory. This was just a cool story I saw on the weather channel.

http://www.weather.com/news/weather-winter/5-extreme-temperature-drops-2...

Imagine bundling up to get the newspaper on an early morning at 7:30 a.m. with the temperature at a frigid -4 degrees.

Just two minutes later as you are letting Fido have a potty break on the lawn, you notice that the frigid air you walked out the door into is not so frigid anymore. You look at your thermometer and the temperature has shot up to 45 degrees. That's right, a temperature increase of 49 degrees in just two minutes!

But wait, that's not the end of this wild morning weather story. After the temperature climbs all the way to 54 degrees at 9 a.m., it crashes down again 58 degrees in 27 minutes to -4 degrees once again.

Sounds like a dream, but it's not. All of this happened in Spearfish, S.D. on January 22, 1943.

The National Weather Service in Sioux Falls, S.D. describes the cause of the dramatic temperature changes:

"The wild temperature fluctuations were likely due to cold air and warm air sloshing back and forth along the plains at the base of the Black Hills. A similar effect would be to pour warm water into a shallow bowl of cold water. The water would slosh back and forth a few times before settling down. This is likely what happened with the warm and cold air along the Black Hills."

For our next extreme temperature swing, we go to a city that set a record high and low in one day.

    Blog: Can we please fix the Oscars?

    Summary:  Fun facts: The first-ever Oscar ceremony, held in 1929, ran a brisk 15 minutes. By contrast, the longest was in 2002, clocking in at a monstrous 4 hours and change. As usual, there are things I loved about it and things I didn't. Rather than be snarky or complain, I'll offer a few suggestions on how the organizers might bring the show into the 21st century.

    Winter storm drama

    Athens-Clarke County police officers responded to Pinewood Estates North on a 911 call concerning a heated domestic dispute. it reportedly was an argument over the lack of heat and food in a family's trailer and a woman was threatening to stab anyone who tried to take away her 7-month-old child. State patrol responded also, from their post nearby on U.S. Highway 29 North. The situation apparently was resolved. An officer reported he was driving the woman and infant to another home in Athens. read more
