Well, I am almost convinced there will be a few significant tornadoes tomorrow in western/central Nebraska....centered along the I-80 corridor. Geographically, the setup reminds me somewhat of May 22, 2004, where a surface low developed in far NW kansas with an east-west oriented baroclinic zone. Only this time, it looks a bit farther west. 850mb winds progged to be southeast at 45kts from the Eta. This is *very significant* and you only get this with vigorous lower tropospheric development and crazy ageostrophic responses with the atmos so out of geostrophic balance..
Good luck to all head out, it could be a dangerous day, and with a ton of chasers out, it is imperitive to stress: safety first. I'm looking forward to seeing all the great video and photographs of what looks like one of the best days of 2005, more than likely.
