Very clear debris signature on the storm that just went through Ava, IL. Went through the western portion of the town.
Unfortunately the low level jet/wind speed maximum typically increases after sunset/in the evening --> this only serves to strengthen the low-level wind shear available to these storms. The 2007 Greensburg, KS tornado was a famous example of an after sunset tornado whose parent storm was enhanced by the increased low-level wind field.
That long-lived supercell is now dealing with the smaller storms to the south merging into it. Mergers can either enhance or decay the main storm; we'll see how this evolves. Hopefully the smaller cells will kill it - precipitate into the inflow region of the main storm --> decrease the buoyancy/instability of the inflow --> weaken the main storm.
Or maybe not... circulation/inflow region to the SE now (near Hanaford)...shouldn't be surprised given the environment these are in
Starting to see the line form now. This should continue into well into the overnight and tomorrow. Line along the front with your more discrete convection - and long-lived tornado/supercell - well ahead of it.
This is why you don't chase at night. You rely on power flashes or lightning to illuminate the tornado
You looked at tomorrow at all? Think we get a moderate risk area? Dixie alley always seems to produce something
