What has been the climate for May according to WeatherCat?

Dear WeatherCat climate watchers,
Another month has passed so it is now possible to see what WeatherCat observed at our local stations. As last month I have a report from WeatherCatRCP with the results:
While the results are literally below normal, they are surely less than one standard deviation so while there was a yo-yo of heat waves and cool periods the net result was average temperatures. That's significantly different from the Climate Prediction Center's outlook for Northern California in June:

According to that graph:
There was a 60% or greater chance of above normal temperatures right up to the coast. I find this disturbing because what actually happened was fairly normal weather phenomena. Instead of uniform heat, there was cyclical pattern of hot weather that was quenched by the cooler air from the ocean. After each heat wave, ocean air was drawn inland leading to several days of below normal weather. The physics is absolutely routine and mundane. It is very much the sort of thing one would expect climate models to be able to easily capture. It is in my opinion another clear example of the science not measuring up to what should be expected given our overall understanding of the atmosphere.

Where I live, on the other side of the Sierras from Edouard, the forecast called for a 70% probability of higher than average temperatures, but it didn't turn out that way. We too had some hot days, but mostly we experienced temperatures that were slightly below average. On the other hand, we only had one very small rains storm, so the rain forecast was dead on.
June was... Cooler than average (58.2?F versus an average of 58.8 )
Dryer than average (0.10 in versus an average total of 0.63)
Windier than average (a wind run of 3253 miles versus an average of 2969)

Dear WeatherCat really localized climate watchers,
Another month has ended so it is time to get WeatherCat's opinion on how it compared to "normal" at your weather station. Here is what WeatherCat reported to WeatherCatRCP at the end of the day for Canebas weather station:
So indeed Northern California has experienced a shift from below normal temperatures to above normal - although this cannot be outside of one standard deviation, so more likely it should count as normal.
On the other hand, there are numerous other indicators that the days in July were warmer than normal. I don't think we have ever run the air conditioner as much in a month as this July. The plants, wildlife and me are all suffering! [sweat2] So far we have not had any wildfires that were very close, but California hasn't been very lucky with that either. So things have changed and most definitely not for the better.
Oh well, . . . . . Edouard

Here in the mountains of Northern Utah:
July was...
Warmer than average (65.6?F versus an average of 62.9)
Dryer than average (1.23 in versus an average total of 1.55)
Windier than average (a wind run of 3195 miles versus an average of 3010)
JosBaz:
June and July have been exceptionally hot, sunny and dry in the Netherlands as a result of persistent High pressure zones over (North) Western Europe.
We've only had 4.4mm (0.17 inch) of rain since mid June -- versus the 'normal' of approximately 100mm (4 inch) -- resulting in a record drought, surpassing the dry summer of 1976.
Several other records were broken:
- with 341hrs of sunshine, July was the sunniest month on record (11 hours a day on average!).
- on 27 July, the temperature did not drop below 23.1C; the highest minimum temperature ever recorded - beating the previous record by more than 2 degrees(!).
- for the first time ever, the Netherlands recorded average temperatures (over 24hrs) of more than 30 C. Not in my area ('only' 29.5C).
Close to the German border, maximum temperatures of 38.2C were recorded, only 0.4C below the all time record of 38.6C recorded in 1944.
My PWS recorded a maximum of 36.9C on both 26 and 27 July.
So far no changes in August: still no rain and yesterday again a maximum of 34.6C.
