Yeah, that was the case in Cleveland as well. I think I read 22”, but unfortunately no official snowfall records at that time. The official records only note 1.85” of liquid equivalent. The article below is probably an exaggeration (20” in 3 hours), but I did read elsewhere there were insane rates… however, if memory serves, it was more like 8” in 2 or 3 hours.

@donsutherland1 @bluewave Retracting my earlier analysis, because I think it was caused by the way NOAA attributes data for the cooperative stations. Most report in the morning and the high and low get attributed to the day of reporting, even though it reflects the prior day. So, I think most of the discrepancy in July was due to the co-op stations having an extremely hot June 30th attributed to July 1, which gave them an extra hot day last month.

You have to take some of these high dewpoints from 1995 with a grain of salt. The chilled mirror sensors in use at the time had to be regularly cleaned or they could produce spuriously high readings.

Incredible. New York has set or tied 10 August monthly hourly dewpoint maximum temperatures during this torrid stretch (based on hourly data to 1943).

No, July 2012 came in 0.04F cooler than July 1936, per NCEI. Close but no cigar. For the whole summer (JJA), 2021 is tied with 1936 for the record at 73.98F.

At least one of those so-called monthly record lows is fraudulent - there's a spurious 18F reading at YNG reported on 5/24 for some reason. Also, strongly disagree with Brian about the upcoming pattern trending away from the record. In fact, this is the hottest stretch of the month starting today. NWS NBM forecast shows several days of 3-5F above normal to close out the month.

Wow, wouldn't have thought it had been that long since a July high below 75F. The coolest Julys of the past would see the entire month's average not much higher than 75F (e.g., 1976 - 76.7F).

Is there a way to fix a data error in the official climate records? I noticed from Brian Brettschneider's map, it was showing a monthly record low at Youngstown - which struck me as odd. I took a look and the low for May 24th is showing up as 18F, which is obviously incorrect. Not sure how that ended up there... it doesn't look like NWS CLE generated/published an RER for that date.

A code *maroon* air quality alert for northern Ohio. Geez, I didn’t even know it had that many colors.

Impressive heat. Highest in the month of July since 2012 at many sites, including Milwaukee and Flint. We will see if O'Hare can tick up to 97F and that would also be the case there. We have seen a couple of warmer episodes in August (perhaps June?), but this will be the hottest July temperatures in 14 years at a number of sites.

MKE was 97F at the last METAR observation. Up to 98F/99F now, per 5 minute observations. Last ob was 99F. Due to rounding probably only 98F, but definitely above 97F.

Looks legit by the way, maybe a tad warm. Checked PWS stations around there and most were in the 100-103F range, even right to the shore.

Wow! 104F now. Really mixing well there - downsloping effects? Dews are cratering with gusty west winds.

Up to 102F at Oscoda, Michigan. Toronto, Ont. was up to 97F at the top of the hour.
