  1. 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...
  2. 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?

    August 2018 General Discussion

    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 General Discussion

    ^ That's some insane UHI at ORD. What could be causing that - the recent change in location of the ob site?
  5. 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.

    Arctic Sea Ice Extent, Area, and Volume

    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.
  7. 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.
  8.    You can find a lot of information about past wind chills in newspapers from the 1980s. Illinois, Indiana, and Ohio had wind chills of -60F(-85F old scale) on January 20-21, 1985. Kansas had wind chills of -50F to -55F(-80F old scale) on January 10, 1982 and December 24, 1983(Oketo reading). Central Kansas had wind chills around -50F to -51F(-70F to -75F old scale) on January 10, 1982 in some areas. Additionally many parts of Northern, Kansas likely had temperatures of -25F to -30F with wind chills of -60F to -70F(-52F to -55F). There may have been colder wind chills in 1989 than the Oketo reading but it would be best to keep with the -52F.

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

    After the incredible humidity over the past week, ORD was 80/32 at 1:00 PM local time today, for an RH of 17%. Haven't seen an RH level that low in Chicago for awhile...and honestly I can't remember ever seeing a dewpoint as low as 32 in July before. Of course the Td’s at ORD seem to be running low recently. Has NWS LOT opened an official inquiry into this? Either way...a brief oasis of intense dryness in a sea of unbearable humidity...and one extreme to the other....kind of sums up 2018 so far.

    Highest heat index by state

    Yes (Olney IL, I believe)...and I even saw an 83 yesterday over the corn fields south of Chicago.

    These CA and AZ numbers are air temps. Because it's so dry there, the heat index is typically much lower than the air temp. I also removed the 100F for Fort Yukon AK, for the same reason. I'll add AR to the list. I'm sure they have had a heat index > 120, but we'll use that for now.

    Thank you sir. On 8/2/1975, peak HI appears to be 114 at 3PM local (temp 103, Td 72). This far exceeds 7/22/2011. I'll go with this for the ME record for now.
