I met Adam Lucio in El Paso, IL just around 3 PM and we saw what would be the makings of those supercells in NE MO/S IA go up. We held out in El Paso a little longer hoping deep convection would fire up to the SW near STL and head up this way.....that was not to be. We finally made the decision to head for Galesburg via I 74 in hopes that the supercells in NE MO would hold together and make it that far. All day it had been this dreary, damp, and a windy overcast all across central IL. This wouldn't change. By the time we hit Peoria, tornado warnings were already evident over Adams County with a confirmed tornado near La Grange, MO. As we hit Galesburg around 615 PM the storm was coming into view to the SW. We dipped south on RT 67 all the way to Roseville. We went west on 116 until we were 3 miles to the N or Raritan. Storm motions were "said" to be N at 55 but it looked like the core was spreading to the E and we knew we had to get out of there. We started back east on 116 when Adam and I noticed a bowl shaped lowering rapidly approaching from the SW. Strong rotation and a possible tornado was reported with this storm and it was only a few miles away so we took no chances and headed back east to 67/116 jct. When we arrived at that intersection the storm looked real ragged and outflow-y so we decided to let it overtake us. As we were sitting there about to get cored I noticed the winds to be strong out of the southwest, in a matter of 30 seconds we experienced several strong blasts out of the east. Having lost data we could only assume the couplet was wrapped in rain and passed almost overhead (later analysis of GR3 confirmed this) We then gave up on the storm and headed north to Monmouth when Adam spun out into a ditch and I had to go back and help him while only a matter of miles to our north our outflow-y storm would produce a rope tornado, captured by Joel Wright and Jeremy Ludin.
Congrats to all who bagged one and to all that had successful chases, this was a good chase for me because my chase forecast/target
....... was right on having 10 tornadoes within a 50 mile radius of there.
Bowl shaped lowering moving North as we were moving east on 116
This was looking into the direction of the rope tornado
Probably not the way you want to end a chase....
