Brief: Was *totally* caught off guard today and not expecting to chase. Departed Kalamazoo, Michigan around 6pm ET and vectored southwestward on I-94 towards NW Indiana (Lake Co). Intercepted a low-topped tornadic supercell near Cedar Lake, Indiana at dusk; encountering intense CG lightning coupled with a massive LP'esque mini-mothership mesocyclone which came into view directly over HW41 apx 6-8 miles to my north. Amazing I saw anything considering the late departure and traffic encountered on HW30 in Lake Co. Indiana.
Summary - Full:
I have hardly even had time to post my reports from the weekend chase to Iowa and Minnesota; which I was going to begin writing until briefly glancing at ILX 88D via the COD.edu webpage. Unaware of the tornadic situation unfolding across northern and central IL until around 5pm ET; I debated chasing due to the proximity of nightfall around 8-830pm CT. The massive low-topped supercell near Peru, IL (along I-80) sold me.... quickly grabbing my camera gear, tripod, and maps... I streaked out the door (fortunately wearing pants) and made my way southwestward. Before departing, I noticed new cells firing up S of Kankakee, IL; either SVR or TOR warned... alas, those were in the back of my mind while driving SW on I-94 in Michigan.
Stopped to fill up the tank in Michigan City, Indiana; and noted on video the amazing amount of visible shear in the atmosphere just N of the warm front. I was in grunge, but peaks of blue/sunshine occasionally filtered through as I made my way into Indiana. Phoned Chris Novy whom graciously informed me of new TOR warned convection just to my SW. Received the NOAA tones and a TOR warning for Lake/Newton Co. in NW Indiana. NWR stated that "a large and destructive tornado was on the ground"; a statement I have never encountered until tonight in NE IL/NW IN. That got the blood boiling as I was slowed by Sunday'esque drivers along I-94/80. Deciding the better play/easier intercept would be the supercells entering NW IN; I committed to the Kankakee storm and shot south on I-65. The northern supercell/updraft tower came into view at dusk as I exited on HW30 and headed west. This feature quickly became obscured, as Novy informed me the stronger tornadic supercell was just to my SW.
Attempted to get through Merrillville/Independence Hill, IN as quickly as possible; as I was hitting HW30 in post-rush hour -- dinner hour (many people were out). Hit all red lights on HW30; annoying me; but I continued on... shooting south on HW41. Novy called back, informing me the 88D couplet was just to my SW between Kreitzburg and Brunswick; thus meaning I had to drop S (HW41 is a great N-S highway BTW) in a hurry. Noticed a large inflow band directly to my south, flowing west into the murky abyss which was a large meso/wall cloud (not visible yet). Stopped a few times to get my barings/check the surroundings; didn't feel safe in 30kt easterly inflow so I dropped south. Now S of HW2 and HW41, I pulled off, along with a truck of local fireman (spotters whom inquired what I was looking at). I informed them about the situation, and it was about this time a large LP'esque mini-mothership came into view directly over HW41 (view was N/NW). Rolled video, but have yet to review what the result was (as I boosted the shutter to 1/3 a second). The local spotters called this into their spotter net, and I proceeded to turn around and head N.
Shot east on HW2 towards Lowell with the "mini-mothership" (resembling a miniature version of Pampa, TX on 23-May-2002) just to my N/NE. The cell rapidly lost intensity once I was driving northbound on I-65 towards it... intermittent lightning noted.
Was SHOCKED and saddened to learn about the large and deadly tornadoes across N. CEN Illinois today. Like most people; I was unaware of the developing severe weather situation until the event was in progress. What *really* shocked me was that SPC totally missed this... *yet* LOT NWSFO (Chicago) did a *fantastic* job of getting the warnings out on a last minute/and timely basis!
*MANY* thanks to nowcasters Chris Novy and Scott Kampas... your eyes on the electronic sky were extremely valuable, considering I was chasing alone... at night!
It just goes to show that no matter how much technological and meteorological know how is in place, the atmosphere dictates it's own behavior and does not adhere to the electronic boundaries set fourth by we humans. My sincere condolences to those lost in the winds of this terrible Tuesday in N. IL and the upper midwest. Yet on the other spectrum, congratz to all those whom chased and witnessed nature in all its fury and awe.
