The fact that 1980 is lower than "expected" on the list of warm summers could be driven by overnight low temps, which have warmed much more than daytime highs in recent years...likely due to UHI and climate change. Plus, I believe 1980 was dry overall...which could have led to cooler overnight lows (all else being equal).

Rockford 80/35, RH 19%. Very rare to see RH < 20% in Illinois.

Waukegan dropped to 38 this morning, Rockford 39, and 41 here. 26 in Rhinelander WI; missed the record low by 1F.

Low of 30.

It's always interesting to see lists like this in the Spring for Chicago...as the dates are always old. This is because the official Chicago obs were right on the lake in the olden days. The official site moved to O'Hare (ORD) in 1980. Needless to say, it makes Chicago weather records a bit misleading and difficult to interpret. It probably won't matter much in this case anyway, as there will be a midnight high around 60 at ORD.

If Denver gets more than 3.8", it will be their 3rd largest snowstorm on record for so late in the season. They had 10.7" on May 25-26, 1950 and 5.6" on 5/29/1975...which are both insane. Latest measurable snow was 0.5" on 6/5/1953. Possibly even more impressive - if the temp drops below 30 this weekend, it will be the coldest ever for so late in the season. It was 30 on 6/2/1951, but has never been colder than 30 after May 19th. Records go back 150 years, to 1872.

The 96 in Traverse City is insane. The low of 74 yesterday morning in Rockford barely held on through 1AM …so a new all-time warmest min temp record for May was set. Old record 73 on 5/22/1905.

Ha. If the forecast said "clear" with isolated showers, I could see your point...but it said "mostly clear"...which leaves some wiggle room. Just semantics, I guess.

"Mostly" has a probability and/or coverage element to it. My interpretation of "mostly clear" is that it's expected to be clear 80-95% of the time at a particular location. So, it could still be cloudy and/or rainy for the other 5-20% of the time. As I understand it, that could mean either (1) a 5-20% chance of any clouds/rain occurring in the region, or (2) it will definitely be cloudy/rainy in the region, but with only 5-20% coverage.

Yep - ORD's low was 74 this morning...same as yesterday. And today's low should hold through 1 AM tonight - although dews may come down a bit later, so it could be close. Old record high mins: May 11th: 70, set in 1881 May 12th: 66, set in 1956 Not often you break a daily record by 8F, especially with a POR of 150 years. And Rockford's high of 94 yesterday is the hottest day so early in the season in the past 88 years (it hit 96 on 5/9/1934). Even more amazing - if Rockford's low temp this morning (74) holds, it will set a new May monthly record for the warmest min. Current record is 73 on 5/22/1905. In fact, there have only been 5 May days in Rockford's history with a daily min of 70+. With all that said, I think there's a decent chance (1 in 4?) of dropping below 74 prior to 1 AM.

Yep, good point. It’s 90/73/100 here, just before noon…unbelievable.

Assuming it holds through midnight (which should be no problem), ORD and RFD both shattered their warmest min on record for so early in the season. Low temps this morning, May 11th: - ORD 74; previous earliest low temp this warm was 74 on 5/19/1911. - RFD 72; previous earliest low temp this warm was 72 on 5/18/1996. Meanwhile, it has been very cold out west. West Yellowstone MT dropped to 7 yesterday morning, and Eureka CA (right on the coast) dropped to 37.

Yuck - incredible to see a dew of 74 on May 10th. 88/70/95 here.

Rockford could set record warm mins for 4 consecutive days. Here are the records, going back to 1906: 5/10: 65 in 1979 (today's low 68 so far) 5/11: 63 in 2011 5/12: 64 in 2004 5/13: 63 in 1991

Amarillo TX is currently 84/20, RH 9%...and there's a frost advisory for tonight (around 35F)...then back up to 75 tomorrow.

Embarrass (one of the coldest towns in MN) dropped to 10 this morning, helped by some modest snow cover. This is their 2nd coldest temp on record so late in the season...although records only go back to 1994. It was 4F on 4/27/2004...wow. Their normal low in January is -9.

Dropped to 29 this morning...not bad for April 27th.

Update: INL has broken the record, as April 20th is the 160th consecutive day with 3"+ snow cover. Amazingly, the depth has actually increased throughout April...now at 17". It was 15" on 4/1. Looks like the streak will end on 4/24, as temps in the 50s with high dews will probably obliterate the snow pack. Also, a new daily record low of 8F on 4/19; old record was 15F set in 1947. This is also the 3rd coldest temp on record so late in the season for INL. The only colder mins were 4F on 4/20/2013 and 6F on 4/23/1909.

Yeah, it has been an unbelievable week up there. Bismarck didn't see as much snow (only around 20"), but the cold temps there have shattered daily records. It's even more impressive because the period of record goes back 148 years, to 1874. - April 15th: Max temp 25. Old record was 32, set in 2011. - April 16th: Min temp 0. Old record was 10, set in 1953. Coldest temp so late in the season, by far…as the previous latest 0F or colder was -1 on 4/5/1996. - April 18th: Min temp 6. Old record was 12, set in 1988. 2nd coldest temp so late in the season (min of 4 on 4/19/1928).

And Bismarck dropped to 0 this morning. Old record was 10, set in 1953. It’s also their coldest temp so late in the season, by far…as the previous latest 0F or colder was -1 on 4/5/1996. Records go back nearly 150 years, to 1874.

Based on the forecast over the upcoming week, INL will set a new record for consecutive days with 3”+ of snow cover. The streak will definitely hit 158 days, maybe even 160 if everything breaks right. Previous record was 157 days in 1995-96 (11/10/95 to 4/14/96).

Not sure if any stats are available on this...but INL has to be close to their all-time record for consecutive days with 3" of snow cover. Snow depth was 3" on 11/12/21, peaked at 26" on 2/22/22, and was still 11" on 4/13/22. That's 152 consecutive days, and counting. With chilly temps in the near-term forecast, the streak could continue until April 20th...or even a bit later.

Looks like much of ND ended up with 18-30" of snow. Highest report so far is Glenburn at 30.5", with 3 NNW Minot at 30"...and it's still snowing. Record low max temps could be shattered tomorrow, and record lows could be shattered on Saturday morning. Here is Bismarck, as an example: - 4/15 record low max 32, set in 2011; forecast high 25 - 4/16 record low 10, set in 1953; forecast low 7

Yeah…Minot ND is expecting 24-30” of snow. An incredible storm.
