Wmsptwx Posted July 13, 2015 Share Posted July 13, 2015 Could potentially be a PDS Severe Thunderstorm Watch Maybe, wording seems to see it more as wind threat than TOR. Link to comment Share on other sites More sharing options...

cyclone77 Posted July 13, 2015 Share Posted July 13, 2015 Could be getting something trying near Cedar Rapids... Cross section shows tops of near 40KFT. Can it break the cap though? She's a tryin'. Westernmost cells will be absolute beasts. The Roanoke cell was the westernmost sup. Not saying that is going to be the case today, but something to consider.
