As another follow up to Jake's and Dima's posts I saw that Greg Corbin (Warning Coordinating Meteoroligst for SPC) has put together a nice trend plot for April tornadoes. I figured I would add it to the page because he statistically shows what Dima was talking about and goes as far as to say, "More tornadoes are being reported, on average, than ever before and this appears to be due to secular/demographic changes in the reporting process." On this plot you can clearly see 1974, which was referenced by Dima, as the most signifcant Tornado April on record mainly due to several outbreaks that occured during that month.
Through yesterday (4/26/11) the April 2011 preliminary report total has swelled to 683 and again this number is sure to rise as more reports from yesterday are coming in as Storm Damage Surveys and radar studies are being conducted by the NWS offices. Today is also another HIGH Risk day with likely more potential than yesterday. I also wanted to throw out another couple of pretty impressive preliminary stats for this month: 16 of the 26 days thus far have had at least one documented tornado, 10 days with more than 20 tornado reports, 5 days with more than 50 reports, and 2 days with over 100 reports.
