Sorry I missed this. Dr. Roundy has analysis of VP200/OLR filtered by frequency for MJO/CCKW/LowFreq/ERW.

That’s pretty yikes. SPC is very good in areas where tornadoes are more common, but definitely some notable misses in areas with terrain/less-favorable climo.
Edit: 3 more confirmed touchdowns (Sykesville, Baltimore, and Columbia). Bonafide tornado outbreak now with no warning from SPC.
