tornadotony Posted June 24, 2013 Share Posted June 24, 2013 With the very unstable airmass over nrn IL/NW IN and the RIJ driving this thing, it's gonna be a rough night for the Chi metro. Link to comment Share on other sites More sharing options...
wisconsinwx Posted June 24, 2013 Share Posted June 24, 2013 I'm thinking Geosland and just south has the best potential with this. The only question is how those easterly winds will affect the squall line coming in. Timing won't be an issue. Link to comment Share on other sites More sharing options...

Indystorm Posted June 24, 2013 Share Posted June 24, 2013 Love Gino's embellishments in his AFD's and updates. A serious forecaster but not afraid to catch one's attention. That is one mean MCS heading east along I-80 and environs. Link to comment Share on other sites More sharing options...

Geos Posted June 24, 2013 Share Posted June 24, 2013 I'm thinking Geosland and just south has the best potential with this. The only question is how those easterly winds will affect the squall line coming in. Timing won't be an issue. Winds have shifted offshore again here. Sticky, higher dewpoint airmass has moved back in. 82 here right now. It's been a battle for the last 2 hours, but the offshore flow is taking over.
