Thanks to this neat weather tool, I won’t ever have to screen capture radar images on the road again.
This sequence is from the Woodward tornado on 4/14-15/12. Notice how everything clears up in the late evening and then a squall line forms along a boundary very quickly. The clearing in the late afternoon led me to a false sense of security: the cells are all northeast of me, and moving away from me rapidly.
Try to just focus on the radar, I didn’t want to have to crop the 110 images that made up this slide show.
