Maybe a dumb question but why does the SPC Mesoanalysis show CAPE in Illinois? I doubt we've accumulated 1000 J/kg under clouds all day. 

It was mostly advection driven destabilization.

Lol you work inside

i'll say, for someone who used to work outdoors, this would have been chalked up a good spring in my books.

Nice sup heading right at us.  If it can get it's act together this could get interesting.

it's giving it a go as it approaches you.

we'll see if our luck continues with some clearing later

for the illinois end of the risk tomorrow, it looks like a (big) hailer day.

that 5% hatched tor is way overdone.

Flipping between snow and ice pellets since then.

Flipped fully over to snow now, with about a 1/2" down.

Flipped to ice pellets here a bit ago.

Probably 0.1” of accumulation or so.

Looks like guidance finally has a handle on things, as confirmed by how radar is shaping up. Kudos for the Euro leading the way over the past 18-24hrs.

There’s going to be one heck of a snowfall gradient from NW-SE across the heart of the LOT CWA.
