Despite claims of “severe weather is increasing”, and even after several days of tornado activity in the Midwest and the South, 2014 is still below normal compared to recent years according to data published by Greg Carbin of the NOAA Storm Prediction Center.

What is most interesting is that the recent tornado outbreak that stretched from Arkansas to Georgia marked the end to a streak of 159 days without a tornado ranking an EF3 or higher on the Enhanced Fujita scale (which goes from 0 to 5).As we reported earlier on WUWT, we were in a tornado drought: Tornado season so far may be the slowest in a century
Greg Carbin, the man in charge at NOAA’s Storm Prediction Center (SPC) provided this graph and says:
Likely the slowest start to tornado activity in any year in modern record, and possibly nearly a century!
It got busy very fast though. There were only 20 tornadoes up to April 20th, then 93 tornadoes in storm reports up to April 24th, but then SPC recorded 87 tornadoes in storm reports alone on Monday April 28th, many with fatalities (preliminary data, and may be subject to revision once investigations are made on storm events).
I find it interesting to note that he past three seasons have all been well below the 2011 tornado season, which had the second highest tornado count on record and was much ballyhooed by climate alarmists as the defining link between severe weather and climate. 2012, 2013, and 2014 so far seems to be an inconvenient anomaly for those claims.
Another claim was that the flooding in Pensacola, FL, which got over 29″ of rain, setting a new record, was related to climate change.
PUBLIC INFORMATION STATEMENT NATIONAL WEATHER SERVICE MOBILE AL 1100 AM CDT FRI MAY 2 2014 ...RECORD APRIL RAINFALL... PENSACOLA... PENSACOLA RECORDED 29.53 INCHES OF RAIN IN APRIL WHICH WAS 25.21 INCHES ABOVE NORMAL...MAKING IT THE WETTEST APRIL AND WETTEST MONTH EVER RECORDED. PREVIOUS APRIL RECORDS 24.46...2005 17.03...1937 15.52...1964 13.90...1918 WETTEST MONTHS 29.53...APRIL 2014 24.46...APRIL 2005 21.43...AUGUST 1935 21.14...JUNE 1994 NOTE: PRECIP AMOUNTS FOR 04/29 AND 04/30 WERE ESTIMATED FROM NEARBY WSR-88D DUAL POL RADAR DATA DUE TO A POWER FAILURE ON THE AUTOMATED OBSERVING SYSTEM AT PNS ON THE EVENING OF 04/29.
Scott Sistek reports:
At one point Tuesday, Pensacola received 3.39 inches of rain — in 27 minutes! They were up to 3.95 inches in 34 minutes, 5.68 inches in 1 hour and 15.55″ in 24 hours! Actually, the 15.55 is an estimate as their automated rain gauge failed amidst the deluge. A separate weather station nearby recorded 17.7 inches, while other estimates in the area were as high as 22 inches.
With rainfall rates like that, street flooding is no surprise.
Eric Holthaus, who some may remember as “get a vasectomy to save the planet” guy said on Slate:
‘It probably wouldn’t be correct to say that climate change caused Pensacola’s floods, but it surely made them more likely. Climate change is playing a role in extreme rainfall events like the one on Tuesday’
I loved Dr. Ryan Maue’s reply:

But, look at this table, and note when the events occurred – well before our current spate of worry about “climate change”.
thank you Ryan for using “global warming”…
So a temperature increase you can’t even see on a thermometer is supposed to cause all this…….

RE: U.S. Record Rainfall Events happening before “Climate Change”…
The same is true for Global Rainfall Records::
http://www.nws.noaa.gov/oh/hdsc/record_precip/record_precip_world.html
Will the colder winter essentially mean that the Spring tornado season will go later this year in the US? A later start and later finish?
We must be approaching the time when alarmists will routinely claim that ‘climate change’ is causing more meteorite strikes.
What’s that? A little red dot in Phoenix Arizona? OMG its worse that we thought!
I had to look it up and sure enough a small tornado was reported in March. The NWS gave the tornado a preliminary rating of EF-0, meaning it had winds of 65 to 85 mph.
The weather service said the tornado was about 10 to 20 feet wide and touched down in a nearby park before skipping through the apartment complex.
“Several residents reported seeing the tornado and a flying hot tub.” Yes, really. Fortunately no one was in it at the time.
We do get microbursts here occasionally during our “Monsoon” season, but tornadoes are quite rare.
One thing to keep in mind, some of these old rain rate records are likely erroneous. For example, I’m rather skeptical of the 1-min rain rate record. If you go back to the original report in Monthly Weather Review (http://docs.lib.noaa.gov/rescue/mwr/087/mwr-087-08-0303.pdf), you can read that this amount fell “in an estimated period of 1 minute”. Still, extreme rainfall is probably only ever-so-slightly more likely now than in the planet’s barely colder past.
The table shows a place in Pennsylvania called Smethport with a summer 1942 storm. I made it there for a wedding about 1963. Neat little town with lots of Whitetail Deer in the surroundings fields. Global warming wasn’t an issue in 1942 or 1963 so we didn’t talk about it. Here is a link to a few comments, but not much info on the issue:

You should not have said this could be the mildest tornado season in a long time. Mother Nature does not like to be challenged. Kinda like washing your car during a dry spell.
I find it so funny that we are now reduced to arguing about the weather. I only state this because when there was clear global warming Warmists did not want to talk about the weather. Now, even daily heavy snowfalls, cold, rain, a hot day, locust swarm, high tides, 1 month drought etc. are sure signs of
global warmingclimate change. This can go on forever!!!And it’s all our fault.
I wonder why the Alarmists thought that they would do better with “extreme weather” than with “global warming?” Anyone? Maybe they thought any change of subject would be helpful to them.
1.23″ in one minute! That is impressive! It must have been coming down like rifle bullets!
How do we arrive at 48% with those two numbers? Looks almost dead-on to 50%, like 49.9. A reason?
“2014 tornado count about half of normal”
Yet again WUWT adopting adopting the warmist’s concept of “normal” weather which WUWT has been decrying for years.
So why is 2005-2013 , a rediculously short period, considered to be “normal”. Why is this the cherry-picked “average” the new period of reference for 62 years of data ?
This recent peroid itself has been very low activity, it is hardly the norm against which everything can be measured.
Theo: I wonder why the Alarmists thought that they would do better with “extreme weather” than with “global warming?” Anyone?
Because it’s a non falsifiable claim (they learnt that lesson with global warming), and there’s always some extreme somewhere on the planet that they can latch onto to spin the myth.
The fact that a non falsifiable claim has no scientific value ( anti-science as they would say ) does not worry them because the crowd of idiots they are preaching to do not understand science.
When there are no more extreme weather events anywhere on the planet we can start worrying about a fundamental change in climate. They want to regards that as “normal”.
Recent years 2005-2013 are among the lowest of the record , if the recent outbreak is 48% of that, it is insignificant. It’s misleading of NOAA to use that as a reference:

What a travesty…….
Anthony, Please could we stop using the political term ‘climate change’. They mean global warming so let’s use it.
When some time soon, when skeptic science predominates and people look at the evidence and not the “consensus science” view of eco-politicised academics, I suspect this reduction in Tornado activity may be cited as the first real sign of the effect of rising CO2.
And it will be noteworthy that the first people to highlight it were the skeptics.
2014 tornado counts are so low that it broke the previous record for the first F3 tornado (Mar 31) by a whopping 26 days. Even more remarkable is that these low nominal counts are *before* you adjust for increased population and better tracking technology.
Severe weather.
if the MSM kept pumping stories like this – “How much more cold can the world take”- April/May
Wouldn’t take long for everyone to be alarmed by a coming little iceage.
“This year is maybe a record-breaking year,” says expert on Great Lakes ice.
As of May 1st, ships were still being escorted with ice breakers on Lake Superior, says the Duluth News Tribune.

Why would you want to buy a house in somewhere called “Tornado Alley” anyway.
richard says: “if the MSM kept pumping stories like this”
They may once have been the “mainstream” media, but now the “mainstream” is the internet and social media.
Indeed, with advertisers leaving them in droves, with online news content taking over and with high quality skeptic science sites like WattsUpWithThat now taking over in areas like Climate, one can hardly describe these press-release sausage machine, “10 stories a day per ‘journalist’ and little or no fact checking as “mainstream” – I now call them the “Dinosaur News Media” because many are heading toward extinction.
Assume we accept the premise that “climate change” causes “severe weather”. It is logical, then, to conclude that no “severe weather” implies no “climate change”. The only other alternative is that “climate change” does not cause “severe weather”. QED

‘journalist’
——————————–
A sad and contrived term, the only use for which is to distinguish its subject from “reporter”, whom we imagine as actually pursuing facts.
