tornadotony Posted October 3, 2013 Author Share Posted October 3, 2013 I'm not sure why though, as it will certainly be an issue south of the immediate triple point area. (If I were chasing I would definitely stay north of I-80.) Actually the more I think about it the similarities to 3/29/28 are uncanny, maybe shifted a bit south to straddle the IA-MN border. And with greater instability... Link to comment Share on other sites More sharing options...
ZackH Posted October 3, 2013 Share Posted October 3, 2013 Still worried about a convective mess... but the ceiling is too high to sit this one out. Link to comment Share on other sites More sharing options...
Quincy Posted October 3, 2013 Share Posted October 3, 2013 And with greater instability... The only thing I noted was the time of year, as the temperature gradient is less extreme as the March 1998 event. That upper level trough cross the West was very deep. Otherwise the surface features do have some close similarities. Link to comment Share on other sites More sharing options...

Ian Posted October 4, 2013 Share Posted October 4, 2013 storms finally went up in nebraska.. not bad. tor warn in wi too. Link to comment Share on other sites More sharing options...
ZackH Posted October 4, 2013 Share Posted October 4, 2013 I don't want to buy too much into the 18z suite... but it appears that they have trended further west. I'm not too excited about the early discrete stuff forming in NE on the other side of the river. I would be a lot more comfortable if I could just stay on the east side of the river and chase until dark in IA/MN. Anxiously awaiting the 00z runs.
