SPC annual tornado trends chart: need more data

[Jonathan Whitehead]

By now everyone is very familiar with SPC running annual tornado trends chart

And if your like you me your checking it at least once a week. It sure is nice to look at with this year sticking out like a sore thumb. However, you notice the chart only goes back to 2005. So in the big scheme of things the chart doesnt put this year in perspective. So I would like to extend this chart back to 1999. However I cant seem to find that sort of data as easily as I thought. So if anyone could help me out with this, I would greatly appreciate it.

Chris, go to this link and download Severe Plot, and it's updates. It's the best thing I can offer. Also, this is the most active start of the year for tornados since 1999.

The data so far this year is really quite striking, especially when plotted out beside the other years. It'll be interesting to see how April and May pan out this year, as that's when I'll be chasing.

Chris, thanks for the link and info. Nice little app.

Its amazing what two outbreaks can do to these stats. Based on the information given the last 4 years, we should be in late April/early May by now.
