Rainfall estimates from the Oklahoma City NOAA WSR88D radar. Over 10 inches caused massive flooding in the city yesterday.

I wrote a post awhile back (See TENNESSEE FLOODS- CLIMATE RELATED?) on the possible climate connections to the Nashville flood. Since then we have had another two major events.  One in Arkansas that killed 20 and just this week a deluge in Oklahoma City that caused all three major interstates to be closed and a day of rescues.

As I said in the previous post, you cannot blame any one weather event on climate change, but with the atmosphere holding about 7% more water vapor (Because the planet is warmer) it is very suspicious that we are seeing so many 100 and 1000 year floods.

Joe Romm over at the blog Climate Progress has an interview with Kevin Trenbirth of NOAA NCAR that is well worth listening to. My buddy Stu Ostro at the Weather Channel gets a mention too.

It’s about this very topic. This on the same day that NOAA announces that May 2010 like April was the warmest on the thermometer record.

The data seems to be adding up. As far as normal weather goes, we live in a different world than existed in the 1950’s and 1960’s.
