I forgot about that anomalous heat last September...I guess I try to block out warm wx as much as possible. 7 consecutive daily records...wow.

Looks like Boston had a max/min of 98/81 today...crazy for the time of year.

Min temp at ORD this morning was 78...should be able to hold this through midnight.

Interesting...I have seen comments in other sub forums suggesting that a weak and/or Modoki El Niño may be on the way...which would generally be good for our area. I guess it all just shows that it’s still a bit early to speculate. But we should have a much better idea in 3-4 weeks.

Good point about the corn...and even in Chicago metro, the prevailing W or SW winds may advect some of the higher-Td air from the cornfields into the area. There is something unsettling about humans altering their environment so much, that it impacts local & regional climo so significantly...

I've been thinking how rare it has been over the last few "summers" (which I define as June 10th - Sep 10th at ORD due to the colder lake temps in early June) to have comfortable mornings...or even "normal" mornings. So far in 2018, about 70% of days in this time period have had above-normal low temps at ORD...and it's probably similar for 2016 and 2017. Some of this is UHI...but warmer mornings during this 3-month "summer" period seem to be occurring over all of the Chicago metro, not just ORD. In July, the normal low is around 65...so you'd generally expect the same # of days with lows of 70+ vs. lows in the 50s. But here are the numbers... July 2016: 10 days with lows of 70+, 4 days with lows in the 50s July 2017: 7 days with lows of 70+, 1 day with lows in the 50s July 2018: 10 days with lows of 70+, 1 day with lows in the 50s July 2016-2018 Total: 27 days with lows of 70+, 6 days with lows in the 50s I hope this isn't a "new normal". In summers past, I remember many instances when a cool Canadian high would come down, with dry dewpoints and highs in the 70s and lows in the 50s...even during the peak of summer. It seems like we rarely get these days anymore. Is it because the arctic/Canada is generally warming...and therefore the source region for these air masses is warmer? Or, is it simply UHI in all of Chicago metro, not just ORD?

And the INL hourly obs were interesting...it was 56/49 at 9 PM last night...then 35/35 at 6 AM this morning...then up to 50/50 three hours later. Is that indicative of extreme radiational cooling...where both the temp and Td dropped significantly for a brief period of time, then recovered? You don't see that too often, especially this time of year.

July 2018 will end as the warmest July on record in Key West FL, with a mean temp of 86.9F. Even so, it's only a +2.3F departure from the 1981-2010 normal. On July 26th, the max/min was 93/86...yuck. The only hotter month was August 2007, with a mean temp of 87.5F.

Not sure if this is the appropriate thread...but the dewpoint at Barrow (Utqiagvik) AK hit 58 yesterday. That is shocking to me...at 71.3N, right on the Arctic Ocean.

The core of the heat isn't even over TX yet...and Dallas (Love Field) is currently 107/61/109. Assuming no remnant clouds from potential storms to the north tomorrow and Friday, you'd have to think 109-110 is possible.

Las Vegas actually had a dewpoint of 74 yesterday. I wonder if that's a new record? I didn't think such high Td's were possible in that part of the world. I know the monsoon visits the area in July-August, but my understanding is that the greatest impacts are typically further east than Las Vegas.

Hope you're enjoying your time there. What part of Iceland?

http://ak-wx.blogspot.com/2018/07/possible-el-ni-modoki.html Those Modoki analogs would be great for the Midwest...especially 1977-78 and 2014-15.

Good catch on ND. I updated the list (and OH too, per the other post). Christmas Eve 1983 must have been a great night for the good folks of Williston to sit in front of the fireplace and enjoy the holiday spirit. Those are some good old-fashioned winter conditions...wow.

Yeah, I was 9 years old for the December 1983 arctic outbreak, living in the Chicago suburbs. It’s my first weather memory.

Good catch...the -52 seems legitimate. I updated the list (1st post of the thread). Same with your comments upthread for HI, OR, WA, MA.

Nice. That is an insane airmass...-23 in Akron OH with a 21 mph wind out of the SW. Wow...

Very rarely in that part of the world. In fact, they hardly ever occur even in the Chicago area...where winter temps average about 6-8 degrees colder than northern KS. As an example...despite the fact that 1/6/2014 was a brutally cold and windy day in northern IL, wind chills "only" dropped to around -45.

Good find. In those hourlies, I see -21 with 16 mph wind, and -22 with 14 mph wind. Both result in a WC of -47. The intra-hour reading showed a 16 mph wind, but no temp to go along with it. Again, can't take it too seriously; part of the challenge and fun of science is putting the pieces together and finding/analyzing data. The planet has been around for a long time...I'm sure some of records will be broken in the next 50-100 years. Some of it depends on timing and having a better observation network now; we don't need to hope that the extreme events occur only at the major reporting stations. For example - if the record cold in Bartlesville, OK in Feb 2011 occurred a generation ago, we would have probably never known about it. Same with tropical storms in the middle of the Atlantic. Just part of the journey. I've updated the list in the first post of the thread; it's easier to keep track there.

Oops. I got it from this article...I guess they missed it. https://www.pressherald.com/2014/01/04/how_low_can_portland_temperatures_go__/

I poked around and looked for hourly temp/wind obs in Maine during late Feb 1943, but no luck so far. The -39 in Portland is even more shocking because, not only does it blow all other low temp readings out of the water in Portland...but it occurred relatively late in the season...on 2/26/1943. A cool 58 degrees below the 1981-2010 normal low of 19. Yikes.

Nice graphs...and for those interested in AK weather & climate, that Alaska-wx blog website is great. Wow, nearly every single day from Nov 2017 - Mar 2018 was above normal in Barrow (and these are recent normals, i.e. 1981-2010)...and many of those days were way way above normal. Perhaps it's not too surprising, as the persistently low amount of ice north of Barrow over the past 10-15 years significantly moderates the temps in Barrow due to E or NE flow...but still.

There aren't many things in science that remain undiscovered or undocumented..and I've never been able to locate a list of WC records by state anywhere. A fun little science/research project.

Ok, come on...this is not meant to be personal. All I'm trying to do is have a good list based on verifiable numbers. I'm a scientist, so it's important to have quality control of the data. It's not a personal vendetta. If others are estimated besides IN and KS, you're right that they shouldn't be on there either. It's a work in progress.

Ha...got to fill the summer downtime!!
