Late January-Early February Clipper Train
Chicago Storm replied to Hoosier's topic in Lakes/Ohio Valley
Look locked into a 2-4” event tomorrow. I’ll go 3.0” ORD. . -
This is advection cold, not radiational cold. Thus, the cold is about the same everywhere. Tonight will be radiational cold.
-
ORD down to -17. Already broke the daily record low of -15, set in 1966.
-
ORD has dropped 4F in the past hour...down to -13 now. Once that front past, the advection really ramped up. Too bad it was literally 10mins too late for the one record.
-
-20's temps and -50's wind chills have entered NW. Illinois. DBQ now -22 with -51 WC.
-
ORD -10 as of midnight. All time record low max temp of -11 will stand.

2-4" -
ORD was -6 at 8:30. Everything is on track. The coldest push of air is incoming. Its coming in waves... -10's entering NW. Illinois now, -20's in SE. Minnesota now.
-
Let me just put this right here...
-
0.3" ORD and 0.1" here today from the Arctic snow showers. DPA even reported +SN for a brief time.
-
A majority of that is OBS sites reporting the blowing snow as falling snow.
-
Temp drops of 3F/hr moving into ARX/DVN CWA now. Mason City dropped 3F in last hour, for example.
-
You were wrong last week, and will be wrong again this time around.
-
And there it is... RAP the first showing -40's in the region. -41 near SQI 12z Thur morning and -32 ORD, with temps still dropping.
-
Already seeing widespread school and business closings for tomorrow and Thursday. Probably going to be the biggest combo of closings in a very long time.

Looking like a few inches possible on Thursday, before we head into the melt on the weekend. . -
ORD added an additional 0.8” this evening, to make the storm total 5.0” Added 1.0” here, for storm total of 5.2” .
-
There’s a few SREF plumes near -42 for FEP tomorrow night. .
-
4.2" final total at ORD.
-
The low snow ratios didn’t have to do with the wind. The flakes I was getting were not shattered, but more like pellets or grains a majority of the time. .
-
Slowly starting to get into range on the HRRR. This is just by 0z tomorrow evening... .
-
Snow just ended here. Finished with 4.2” .
-
Still pouring small flakes here. Up to 2.4” this far. Backside passing MLI/DVN now, so probably will end up around or just over 3” when it’s done. .
-
It's kind of looking like that. Probably a 2-5" event south to north across the area.
-
Two things are apparent right now...Guidance that came in drier this evening (NAM/HRRR/ECMWF) had the right idea. Also, snow ratios are much lower, at least to start, than thought. The combo of these two means snowfall totals for most areas will likely under-perform.
