3-Day Outbreak Summary, 4000 Severe Reports

Although one could argue that the late-May severe weather outbreak in the Plains never ended (at least some of the over 4,000 severe spotter reports since May 21st - see previous graphs for 5/21-5/27 - have been in the Plains each day), clearly the last three days have been higher than previously for tornado reports. With that in mind, I provide these stats for Wednesday / Thursday / Friday:

Here is a graph of activity since May 21st:

This week's numbers may have been thrown off by a couple of interesting factors in the mid-Atlantic... for one, some of the warnings were huge, in advance of a long line of thunderstorms coming through Maryland, while smaller storms would have produced a line of individual warnings. Second, this severe line came through the Washington D.C. / Baltimore area which is much more populous than the Plains, so more reports were received per square mile.

*Warning numbers are composited from daily numbers. Due to Z-time, warning numbers could be polluted by previous day or may not contain reports after 00Z. Storm Report numbers are correct because they are 12Z-12Z.
