(The tornado data goes back to 1881. All others come strictly from NCDC's Storm Data record, which makes the data record only from 1950 to present.)
While the data below presents only the positive cases where damage was correlated to a severe weather event, we can surmise that the more-populous areas of the state
REPORT/RECORD more severe events. This may be due to the fact that in the less-populous (forested) areas, we just don't receive the reports - as the events that may
have happened there are not reported. The animals in the forest cannot report trees down or large hail. Occasionally we do get reports from the foresters that a large
"blow-down" of trees has occurred, but those reports are rather infrequent.

The Enhanced Fujita Scale or EF-Scale
Link to the SPC FAQ Page on the EF-Scale
The EF Scale will go into use across the country in Feb 2007. The EF-Scale is meant to further refine
the tornado wind-force classifications begun using the F-Scale. The use of the EF-Scale should lead to more
accurate and uniform tornado strength estimates by investigators.
