  1. Wow...looks like Furnace Creek hit 130F this afternoon, even before the peak heat is expected tomorrow and Sunday. The temp sensor may need to be looked at closely, as it jumped 4F in one hour very late in the afternoon (between 4pm - 5pm local time). Kind of unusual, but I suppose it could happen. Winds went calm, which probably enhanced the heat in the deep valley (near 200' below sea level). Dew is fairly high too, at 48. Heat index 121.
  2. Looks like today will end up with a 116/93 max/min in Las Vegas. The low of 93 is tied for the 6th warmest daily min on record. All of these high min records have occurred in the last 20 years, driven by UHI. Prior to 2002, no daily min above 91 was ever recorded...and mins of 90-91 only occurred 3 times. 95 (7/1/2013; 7/19/2005) 94 (7/12/2020; 7/29/2016; 7/20/2005) 93 (today and 5 other days, all since 2005) The daily average temp of 104.5 is tied for the 2nd highest daily mean temp since 1937. The only higher daily mean temp since 1937 was 7/19/2005 (106.0). That day was actually the hottest day in LV history based on daily average temp - 117/95 max/min.
  3. Note that Furnace Creek is where the official obs are taken for Death Valley. That’s not quite as low elevation as the point & click forecast above. NWS going with 129 on both Sat and Sun for Furnace Creek. What’s interesting to me is there will be some humidity…so overnight mins could be extreme. I could see low temps around 105 over the weekend; could be all-time high mins?
  4. Should be interesting to follow the temps later this week, and to see how high the daily mins will be too (the air isn't as dry as it is during May/June). It stayed above 100 overnight last night, and may do so for the next several nights...yikes. Currently 122/46/115 at Furnace Creek.
  5. I thought the world record temp was 134.1F (56.7C) at Furnace Creek on 7/10/1913. This replaced the previous "record" of 136F in Aziziya, Libya on 9/13/1922, which was invalidated by the WMO in 2012. I know the 134.1F temp is not believed by some, which is understandable...but the WMO currently lists it as the world record. The WMO was quoted as follows: "We accept this Death Valley temperature extreme record. Obviously, if any new materials on it surface, we will be prepared to open an investigation, but at this time all available evidence points to its legitimacy." Anyway - the current NWS forecast for Death Valley (Furnace Creek) shows a max temp of 128 over the next 7 days. I agree they may be playing it a bit conservatively, as it's 5 days out. I think 129 is possible, not sure about 130+. Wednesday: Sunny and hot, with a high near 125. South wind 6 to 10 mph.Wednesday Night: Mostly clear, with a low around 100. Southeast wind 5 to 11 mph.Thursday: Sunny and hot, with a high near 125. South wind 7 to 15 mph, with gusts as high as 21 mph.Thursday Night: Mostly clear, with a low around 99.Friday: Sunny and hot, with a high near 125.Friday Night: Mostly clear, with a low around 100.Saturday: Sunny and hot, with a high near 127.Saturday Night: Mostly clear, with a low around 101.Sunday: Sunny and hot, with a high near 128.Sunday Night: Partly cloudy, with a low around 102.Monday: Sunny and hot, with a high near 127.
  6. Looks like Salem (definitely located in OR) hit 117 before winds shifted to the W and the temp crashed to 85 by 7pm local time.
  7. 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.
  8. 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.
  9. 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.
  10. Forecast for Omak, WA…this is insane: NWS Forecast for: Omak WA Issued by: National Weather Service Spokane, WA Last Update: 3:53 pm PDT Jun 24, 2021 Excessive Heat Warning Tonight: Partly cloudy, with a low around 67. North wind 8 to 14 mph. Friday: Sunny and hot, with a high near 101. Breezy, with a north wind 13 to 18 mph. Friday Night: Mostly clear, with a low around 70. North wind 5 to 10 mph becoming light. Winds could gust as high as 20 mph. Saturday: Sunny and hot, with a high near 106. North wind 5 to 7 mph becoming light and variable in the afternoon. Saturday Night: Clear, with a low around 74.

  11. 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.
  12. Good to hear - I’ve noticed that PWK’s temps seem to be more realistic over the past few weeks.
  13. 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...
  14. 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.
