Are tornadoes becoming more frequent in California?

California's count per decade against the whole country's, and its share. The Storm Prediction Center notes that tornado reports rose especially around the installation of the NEXRAD Doppler radar network in the mid-1990s, so a rising count is partly better detection; the share of the national total is the fairer comparison across decades.
