So how are things looking in the UP @weatherbo and @wishforsnow? Any trails open at all?

Looking like a good thing I was in the UP mid-January this year. You'll have to give us a snowpack update in 10 days or so

Interesting! Definitely not the usual lake effect snow location, see it on the northwest shore of the lake

I think you have the date wrong? ORD was 91/59 on May 30th

Can confirm Thundersnow in Irving Park!

RECORD EVENT REPORTNATIONAL WEATHER SERVICE CHICAGO IL138 AM CDT FRI OCT 27 2023...RECORD HIGH MINIMUM TEMPERATURE SET AT CHICAGO-OHARE...A RECORD HIGH MINIMUM TEMPERATURE OF 65 WAS SET AT CHICAGO-OHARE YESTERDAY. THIS BEATS THE OLD RECORD OF 63 SET IN 1939.

I was wondering what was going on, Chicago was under Air Quality Alerts all last week and the AQI ended up I think staying below 100 each day. Then today nothing! (Until now)

I've been curious about exactly this. The University of Michigan Ann Arbor records go back to 1881 on the NWS site. And University of Illinois at Champaign back to 1888. Would love to know more that haven't moved at all since the 1800s

Yeah this is how they score the AWSSI for that map: https://mrcc.purdue.edu/research/awssi/AWSSI_InfoSheet_2pg.pdf

Creating snow via alchemy lol

So is that a lake-enhanced streamer really hitting Indianapolis area now?

1991-2020 is out now. Although the map definitely has some issues, for example Gaylord & Kalkaska normals should have them in the red

Looks like two derechos in 1995 hit Ontario. I was in northern Michigan for the one on July 13, 1995 https://www.spc.noaa.gov/misc/AbtDerechos/casepages/jul1995derechopage.htm

Yeah if you look at MDW vs ORD 2020 was definitely an anomaly where ORD had a warm bias. Compared to MDW at least. I am using the NWS Monthly Summarized NOWData, average temps at MDW vs ORD

The January 28th lake effect snow event put a lot more snow in parts of the city than ORD
