Kmlwx Posted June 21, 2016 Share Posted June 21, 2016 Latest mesoanalysis has some 100 values for helicity. Also very good hail parameters showing up. Quite unstable locally. Lapse rates aren't as good as they could be but storms already firing so might not be all that important. Link to comment Share on other sites More sharing options...
