Cherry picked data rears it's ugly head again.

Climate change is much more complex than the average temperature of one month in one location.

That is why the usual springtime tornado activity in the US this year is way below normal:

This chart shows the daily count for tornadoes as well as a running total for the year compared to the average for the past 5 years 2005-2009.

Notice that despite a few active days in January, only one day in February produced a tornado. March and April have continued to be quiet. This chart includes data up through Wednesday. Since then, an additional 40 tornadoes have been added on Thursday and Friday. That brings the total for the year of 2010 up to 138, still well below the 452 average ( more likely 470 compared to the same date range)
