hawkeye_wx Posted April 3, 2011 Share Posted April 3, 2011 Looks like Cedar Rapids is getting split. The hailstorm is moving just south and another storm that broke off is moving to my northwest. In between we are just getting light rain with big drops. Link to comment Share on other sites More sharing options...
OceanStWx Posted April 3, 2011 Share Posted April 3, 2011 Should be some massive hail in the Amanas. 65 dBZ well over 30kft, definitely good enough for baseballs. Link to comment Share on other sites More sharing options...
janetjanet998 Posted April 3, 2011 Share Posted April 3, 2011 the KS cell is pretty neat: you can see the front sagging south but just east of the cell its is stalling as the inflow likley is holding it up...then it picks up again just south of the cell with the outlow/RFD Link to comment Share on other sites More sharing options...
cyclone77 Posted April 3, 2011 Share Posted April 3, 2011 Nice sup here west of Sigourney, but the base looks sort of elevated. Beautiful striations. A much lower wall cloud attempted to form but didn't last long. Looks like the storm is cycling. Big new updraft on the flank moving into the base...

hawkeye_wx Posted April 3, 2011 Share Posted April 3, 2011 1.75" hail reported in Amana and 1.00" hail reported in the cell nw of Cedar Rapids. It really is remarkable how we continue to miss hail storm after storm, year after year. I think I've seen half inch size hail once in the last 15 years and I rarely even see pea size hail.

wisconsinwx Posted April 4, 2011 Share Posted April 4, 2011 Extrapolating the storms, it seems far NW Illinois and Far SW Wisconsin will be next in line. I'm curious as to how long these storms hold up, given it's been cool and overcast in Southern Wisconsin most of the day. Not much instability atm.

cyclone77 Posted April 4, 2011 Share Posted April 4, 2011 Our Sigourney cell's wall cloud is reorganizing. Inflow tail is very long now. Still nice rising motion into it. Can't tell if it's rotation since we're driviing east. Rain free base around it is HUGE. Link to comment Share on other sites More sharing options...
Hoosier Posted April 4, 2011 Share Posted April 4, 2011 Got all the way up to 81 here today and still sitting in the upper 70's. Given that and strong southerly flow through the night, I doubt we drop much below 70 before the frontal passage. I'm not sure how much that will help to maintain the storms as they approach but it can't hurt. Link to comment Share on other sites More sharing options...
