Tornado activity hits 60-year low
Source: USA Today
The USA in the past 12 months has seen the fewest number of tornadoes since at least 1954, and the death tolls from the dangerous storms have dropped dramatically since 2011.
Just two years after a ferocious series of tornado outbreaks killed hundreds of Americans, the USA so far this year is enjoying one of the calmest years on record for twisters. Through Thursday, tornadoes have killed only three Americans in 2013; by the end of May 2011, 543 Americans had died.
The seven people killed from May 2012 to April 2013 is the fewest in a 12-month period since five people died in September 1899-August 1900, according to Harold Brooks, research meteorologist with the National Severe Storms Laboratory in Norman, Okla.
The year-to-date count of tornadoes is probably approaching the lower 10% of all years on record, said Greg Carbin, warning coordination meteorologist with the Storm Prediction Center in Norman.

We talk about climate change, but there is still a natural cycle and it appears we're going through the same part of the cycle that occurred in the 30's and the 50's. Climate change did not cause this, but rather it enhances it.

(Though, TBH, watching out for trends is always helpful; we just gotta be careful not to conflate those with obvious coincidences like the back-to-back occurrence heat waves and 2011 AND 2012, that's all)

(111,332 posts)so people downstream in the midwest and Dixie need to pay attention to the weather over the next few days.
This time of year, rain in my area isn't good news for folks farther east.

(29,414 posts)Two weeks ago, and again today we had a deluge (I'm in Houston) along with large hail and a high amount of lightning strikes. I was reading a little bit of Dr. Jeff Masters' blog a week or so ago about how the jet stream had taken a huge dip down into the continent and that was part of why the weather has been like this lately.

(13,685 posts)The few places that did heat up had some storms. But cool air riding into cool air does not cause a lot of uplift.
Or downdraft. Which is recognized for strong winds. A developing theory is that a strong downdraft actually causes some tornadic winds. The basis for that is what goes up must come down. So as warm air rises rapidly it creates space for downdrafts. If you look at some tornado damage you can see that buildings in some cases look like they were smashed from directly overhead: A Downdraft... not sideways wind or lifting winds.
