Weather History for May 25
 
1990   In Barton County, KS a 100 yard wide F3 tornado blew 88 rail cars off the tracks and stacked them 3 and 4 high. One survivor was sucked out of her truck said she was "airborne, trying to run but my feet would not touch the ground!"
1979   In the 1979 Memorial Tournament, Tom Watson shot a 69 in the second round in rain, freezing temperatures, and 30 mph winds in Dublin, OH. That was 10 strokes better than the average of the rest of the golfers that day. He continued to play well and won the tournament. He said he was used to it since he is from Kansas City.
