Record Breaking Warmth in 2012

 

You would probably agree that 2012 was a warm year, but did you know it is the warmest year on record. It beat the old record by one degree.

Here are the top 5:

2012: 55.32 deg
1998: 54.32 deg
2006: 54.30 deg
1934: 54.13 deg
1999: 53.93 deg

From NCDC:

According to NOAA scientists, the average temperature for the contiguous U.S. for 2012 was 55.3°F, which was 3.2°F above the 20th century average and 1.0°F above the previous record from 1998. The year consisted of the fourth warmest winter, a record warm spring, the second warmest summer, and a warmer-than-average autumn. Although the last four months of 2012 did not bring the same unusual warmth as the first 8 months of the year, the September through December temperatures were warm enough for 2012 to remain the record warmest year, by a wide margin.

Charles City Tornado

Forty-four years ago, five tornadoes hit the state of Iowa on May 15. A F5 tornado stuck Charles City at around 4:50 pm. Charles City took a direct hit. The tornado destroyed 337 homes and 1,250 vehicles. Debris was found 35 miles away in Minnesota. One interesting fact is that the tornado left all the bars standing but damaged all eight churches in Charles City. The tornado traveled a length of 65 miles and also hit Elma before dissipating four miles south of the Minnesota border. When it was over, 13 were dead, 2,000 homes were damaged or destroyed and it created an estimated $31.5 million in damage.

Seven mintues after Charles City was hit, another F5 tornado struck Oelwein and Maynard. This tornado traveled over 13 miles. Homes were swept from their foundations. Nearly 1,000 homes were damaged or destroyed with damage totaling $21 million. There were five fatalities with over 156 injuries.

The other three tornadoes were weak compared to these two. A F1 tornado destroyed two farmsteads in Audubon and resulted in one injury. Another F1 tornado briefly touched down in Fayette county at Jackson Junction. The third tornado was a F2 and hit Howard and Winneshiek counties. No fatalities or injuries were reported with this tornado.

Below are just a few pictures from that day:
