Yeah…and Portland’s low of 76 this morning broke the all-time warmest daily min temp of 74, set sometime in 2009. Still 113 at 7pm local time, just crazy. And this isn’t a very dry heat either. At 3pm it was 115/54, heat index 114.

Portland OR hit 112 today, was 110+ for 5 consecutive hourly obs. Previous all time high was 108 (set yesterday). Record before that was 107.

Right, although it’s surprisingly warm there in the summer. July normals are 89/56. All time high is 114 on 7/26/1928, June monthly high is 110.

Wow, that would be historic. I’ve seen dews in the 30s here in early June, but a dew under 40 beyond June 15th is very rare. 20s would be insane. I wonder what dews were like here during the droughts of the 1930s.

Good to hear - I’ve noticed that PWK’s temps seem to be more realistic over the past few weeks.

I could be wrong, but this doesn't seem realistic for RFD. There wasn't a ton of wind/mixing that would support such a high temp, given the background airmass. Seems to be a sensor issue or unusual UHI impacts?? When I say "sensor issue", it could be the sensor itself malfunctioning, or that the sensor is located in a spot which leads to a higher temp when the surface is parched (which shouldn't happen, as it's a hyper-local impact which isn't representative of the area). I know it has been dry there...but it has been just as dry IMBY, and only hit 90 today (which was an overperformer itself). Strange...

The UHI at MSP is ridiculous. At first I thought it mostly occurred in the winter due to more lower albedo, less radiational cooling over snow cover, etc. But it’s just as bad in the summer. St. Cloud, a bit north of MSP and much more rural, had a low of 70. It’s reasonable if UHI adds 2-3 degrees, but not 8. It’s a major problem that needs to be addressed by all of us, led by urban planners and engineers.

And INL hit 98, their first 90+ temp in June since 2005 and a new daily record high (old record 92 in 1988). All-time high is 103, June monthly high is 101. Records since 1897.

Grand Forks had an overnight low of 58, already up to 90 at 10 am.

^ Is that map relative to the new 1991-2020 normals? Would be interesting to see the same map, but vs. the 1961-1990 normals instead. In some areas, 1991-2020 is 2-4F higher than 1961-1990, due to a combination of background warming and UHI. I think the purples would become greens, and the greens would become yellows (in most areas).

And JVL had a low of 50 this morning...nice 40-degree diurnal range with the dry air. Current dew is 37, RH 16%.

Didn’t get as cold as the airmass could have enabled overnight, as the clouds held on for quite awhile. FEP, being very rural and having a longer period of clear skies, dropped to 33. DKB hit 35, and 39 here. Most of N IL was 37-41.

Ha...mostly just the drizzle and wind combined with the temps. Partly cloudy and 45 would be great.

Although I have to admit that 45F and drizzle at peak heating on May 28th isn’t so good. Seasons in seasons...

Wow...18F on May 28th.

Coldest low temps in MN this morning: Hibbing 21 Ely 23 Orr 23 Bemidji 24 INL 24 - new daily record (old record 27 in 1947)

And Marshfield isn't even in far northern WI; it's 44.67N. Light snow (1.75 mile vis), and 33/30 at 6 am. Area Forecast Discussion National Weather Service Green Bay WI 702 AM CDT Fri May 28 2021 Updated aviation portion for 12Z TAF issuance .SHORT TERM...Today...Tonight...and Saturday Issued at 405 AM CDT Fri May 28 2021 Scattered light rain across central and east central Wisconsin will end this morning as the upper low exits the southern part of the state. A little snow may mix in across central Wisconsin. Clearing skies are expected during the day as drier air advects in from the 1030 mb surface high centered over Lake Superior. Highs today will be much warmer than yesterday, but still about 15 to 20 degrees below normal for this time of the year. The computer models forecast the surface high to move into Wisconsin tonight, as a sharp upper ridge approaches from Minnesota. Clear skies, diminishing winds and very dry air are all favorable for temperatures to fall quickly tonight. In fact the precipitable water values forecast for tonight are near the all time lows for late May in the last 70 years of record keeping. Lows in the 20s are a good bet west of an Iron Mountain to Wausau line. Further east it will be in the low to mid 30s. Areas near the lake and bay may escape a frost or freeze but the remainder of the area looks likely to receive one. Record low temperatures are likely in a few places.

This is probably close to the coldest temps on record for so late in the season. The point forecast for INL is calling for an overnight low of 21.

Well said. I only came across James’s posts as an occasional observer in the NE forum; this is so sad. My thoughts are with his family, friends, and all who knew him well on this board. And congratulations to James for publishing his novel. It speaks of dedication, passion, and courage...no matter what stands in your way.

I think this is an urban legend. Besides how insane that would be (just seems to defy any logic)...I can't find any evidence of this occurring. Not that wikipedia is gospel, but the page below shows that MN's latest measurable snow is June 4th (1935)...and earliest measurable is September 14th (1964). No measurable snow has ever occurred in July & August. https://en.wikipedia.org/wiki/List_of_Minnesota_weather_records Plus, this page indicates the all-time record low for Grand Portage in July is 38F: https://en.wikipedia.org/wiki/Grand_Portage,_Minnesota

A dry cold front passed through Las Vegas yesterday, with some incredibly dry air...and cold temps for the time of year. At 3 PM yesterday, it was 85/-19, RH 1%. I've never seen an RH of 1% before, or even 2-3%. It may only hit the low 70s today, and drop into the low 50s tonight. Normals are 91/68.

Some low temps in IL this morning: DPA 30 ARR 30 JOT 32 FEP 32 Here 32...latest freeze imby since 5/18/2002 (31) DKB 33 IKK 34 SPI 34 (!) RFD 35 ORD 37

Actually dropped to 30 here this morning, one of the colder spots in IL as we avoided the clouds. ORD and RFD were in the mid 30s, and even the typical cold spots were 32-34 due to lingering cloud cover. Agree about tonight...thinking 33-35 here, maybe 30-32 in the cold spots. Still pretty chilly for May 12th.
