Large Hail in NW Indiana


Last night large hail was reported in Pulaski county in Northwestern Indiana. You can see a nice hi res picture here from the National Weather Service radar with the hail core diagramed for you. Usually with large hail we see tornadic activity, but that was not the case last night. I'll also attach the NWS statement along with the picture. Very Large Hail in Pulaski County Wednesday Evening

A rare left-moving anticyclonic supercell developed in eastern Illinois and moved into western Indiana Wednesday night. The storm moved through northwestern White County and a majority of Pulaski County between 8:15 and 9:30 PM EDT. As it moved through, the anticyclonic rotation strengthened and a tornado warning was issued highlighting the tornadic threat along with the threat of very large hail. Though no tornadoes were sighted, large and damaging hail was reported all across Pulaski County. The first severe weather report came from Francesville as tennis ball size hail was indicated at 8:45 PM EDT. Two reports of golf ball size hail and a lime size hail report were also received from southwest of Winamac to just east of Ora. The first warnings issued by National Weather Service in Northern Indiana gave over 30 minutes of lead time before any hail reports were received. This storm was a textbook case of a severe hail producing left-moving supercell with the image below showing three tell-tale radar signs of a severe hail:
