It is as bad as... drink plenty of water when it is hot and take frequent breaks. Don't over exert yourself when shoveling snow and use your knees, not your back. Don't stand outside when you hear thunder/lightning. etc. We really do live in a world of stupid people. 2 Link to comment Share on other sites More sharing options...

high risk Posted July 31 Share Posted July 31 18 minutes ago, yoda said: -10 LIs... 5000 SBCAPE... Not sure why they used an 80 dew point to represent the surface, but that is not representative of a low-level parcel. The mixed-layer values (2800 CAPE, -6 LI) are far more realistic. Still a good environment, but the extreme environment that those "surfaced-based" values would suggest. 2 1 Link to comment Share on other sites More sharing options...
