  1. The COCORAHS station in St. Peters (just west of St. Louis) record 11.00" in 7 hours. The station is located 38.8 N, 90.6 W. According to the Precipitation Frequency Data Server this is easily a 1-in-1000 year event.
  2. STL broke the calendar day rainfall record in only 6 hours. The previous record was 6.85" on August 20th, 1915. As of 7am STL had 7.97" today.
  3. HadCET just updated. The highest daily mean in the Central England Temperature record dating back to 1772 just got SHATTERED. Here is the sequencing of the records of the highest daily mean. Date Highest Daily Mean 1772-08-10 22.5 1783-07-11 22.6 1808-07-13 24.5 1948-07-29 25.1 2019-07-25 25.3 2022-07-19 28.1 Here is the full 251 year list sorted in descending order on the highest daily mean for that year. Prior to 2022 the mean of this list was 21.0 C with a standard deviation of 1.6 C. 2022 is 4.4σ above the mean. Note that the distribution is right tailed so that 4.4σ figure may be a bit misleading.

  4. Here is a reminder that the World Weather Attribution group is usually quick to publish their analysis of heatwaves. I would expect something within a month or so regarding this event. https://www.worldweatherattribution.org/analysis/heatwave/
  5. UKMET is reporting 38.1 C at the official station in Santon Downham as the highest of the day for England. That's over there on the east side of England northeast of Cambridge. Very nearly an all time record already. Yesterday's 12Z GFS was forecasting 39 C max for this region. Yesterday's 12Z ECMWF was forecasting 36 C max for this region. Yesterday's 12Z UKMET was forecasting 34 C at 15Z for this region. Despite being biased a tad high GFS performed the best with its 2m T forecast. I'm thinking there is a decent chance we could see 40 C somewhere tomorrow. Today's 12Z GFS is forecasting 42 C.
  6. Wales shattered their all time high. The previous record was 35.2 C on Aug. 2nd, 1990. The new record is now 37.1 C in Hawarden just south of Liverpool. 12Z GFS from yesterday forecasted 37C for this area. 12Z ECMWF from yesterday forecasted 35C for this area.
  7. I saw that the GFS was the most aggressive with its 2m T product. I noticed that it has had a high bias with temperatures in the plains states this summer. I wonder if the same bias is in play here as well.
  8. UKMET is now saying there is a 95% chance that the all time record will be broken.
  9. Just to clarify...all models are showing 38C or higher. UKMET said the odds of > 38.7C were 80% on Friday. Based on more recent modeling I have not seen anything that would undermine that prediction. In fact, if anything, I think the 2m temperature products have actually amped up a bit since Friday. The all time record high appears to still be in play from what I'm seeing.
  10. I just checked this morning's 12Z cycle. All 3 major global models (GFS, UKMET, ECMWF) have the UK maxing out at 38C or higher on Tuesday. The current all time high is 38.7C set on July 25th, 2019 at Cambridge.
  11. The makes the irony of the Watts Up With That blog recently mocking a simulated forecast of 40C in 2050 beyond epic. https://wattsupwiththat.com/2022/06/28/forecast-for-22nd-june-2050/
  12. St. Louis should break two records today. The low only got down to 83 and the high got up to 100. I believe that 83 low will become the highest daily minimum for the entire month of June.
  13. 6.6.2022 thru 6.10.2022 = 11.459e6 km^2 6.6.1980 thru 6.10.1980 = 11.490e6 km^2 Side note...6.6.1980, 6.8.1980, and 6.10.1980 are missing so the 11.490e6 km^2 value is actually the average of 6.7.1980 and 6.9.1980 only. If we use a simple linear interpolation to fill in the missing values the 5 day average becomes 11.499e6 km^2.
  14. That graph is showing the trailing 5 day average which is different than the daily values. BTW...the graph has a quirk where the same date from different years is shifted visually if one of the years was a leap year such as 1980. If you look closely you'll see that June 10th, 1980 was 11.49e6 km^2 whereas June 10th, 2022 was 11.459e6 km^2. So even with the 5 day average 2022 was lower than 1980.
