18z Euro

and total precip

yes that is impressive

12Z Euro is not playing the GFS is on its own with the 2nd wave getting this far north. Nice 6+ from St Louis to Champaign thru Lafayette , Ft Wayne into Mich.

to this amateur it appears the the 12z GFS is similar to 6z but has moved its heaviest snow band back south but we have a few days to figure that out. Happy to see back to back runs like this.

Ride the UKMET

Question for the pro’s why does the GEFS look so different then the op run

Partly cloudy

lotta rain on 18z GFS with a few inches on the backside

Last nights 0z GFS had it coming out in piece the 6z and 12z now show a break in between. I really dont recall a heavy rain event going over to warning level snow. I also think that there is going to be a significant area of freezing rain some where in the Chicago metro area. Long way to go !!! An amateur snowlover take here.

GFS trends for Chicago 0z Total precip 2.60 6z Total precip 1.90 12z Total precip 1.30 following winter trend of south and drier for Chicago

was a typo he meant 10 final call

Oz GFS is snow porn for Chicago area

and then "the over running alignment is different and the storm is south and weaker"

12z GFS still amped still wet and incredibly icy for portions of NE IL (still a week out and as others above have said we havent seen a wrapped up bomb in a long time)

12z Euro loving ALEK next week

I would have close to a foot today based off RAP and HRRR from yesterday. Which hi res model should do the best with lake effect?

3 inches here in Buffalo Grove 11am are these amounts possible or as i believe way over done? close to 16 in the middle of that band

Chicago NWS for lake effect possibility Lake effect snow showers are expected to develop late this evening, possibly across far northwest IN and then spreading west into northeast IL. Confidence for lake effect snow showers is medium to high, but confidence is low for timing/location. Trends seem to focus a band near ord/mdw from the predawn hours through mid/late Thursday morning. Opted to carry tempo mention for lower conditions, but these could become prevailing depending on where the lake effect sets up. And there is some potential for it to continue into Thursday afternoon, especially near ORD and across far northeast IL. Large changes are possible with the lake effect as trends emerge tonight into Thursday morning.
