Was looking at our daily rainfall averages today to see when I could except more rain and noticed something interesting—a secondary wet season mid July-mid August that clearly shows up in daily normals but is totally masked in monthly normals. Monthly it shows a steady decrease from May to the end of the year, but the 2nd peak shows up daily. There’s even a small tertiary peak in September as well.  This means there’s roughly 3 precipitation peaks, from roughly March 25th-June 25th July 15th-August 15th September 10-25th The spring peak is the normal spring wet season, the summer peak is from the southwest monsoon, and the September peak I’m guessing is the first cold fronts of fall while there’s still more moisture in the air. Interestingly, Denver, 50 miles south, has a stronger peak in July and August that shows up in monthly normals. Cheyenne, 40 miles north, has no such peak. This makes it seem like Fort Collins is right about the northernmost reach of the southwest monsoon. |

Muh AGW. These pictures prove that Helsinki was subtropical between 1910 and 1919. We are now only in a cold epoch.

15/24 years within 5 days and 20/24 within 2 weeks. I’m surprised there haven’t been consecutive days with 80s and snow since 2001 though, would’ve thought that would be more common.

One of the worst thunderstorms in world history was "The Great Thunderstorm", which struck Widecome-In-The-Moor, Devon on 21st October, 1638. "Written accounts by eyewitnesses, apparently published within months of the catastrophe,[1] tell of a strange darkness, powerful thunder, and "a great ball of fire" ripping through a window and tearing part of the roof open. It is said to have rebounded through the church, killing some members of the congregation and burning many others." "The head of local warrener Robert Mead struck a pillar so hard that it left an indentation; his skull was shattered, and his brain hurled to the ground." en.wikipedia.org/wiki/The_Great_Thunderstorm#:~:text=The%20Great%20Thunderstorm%20of%20Widecombe,lightning%20during%20a%20severe%20thunderstorm. Wow, I'm glad thunderstorms like that don't happen nowadays. |

Stupid boring northern cocking (blocking, if you couldn't figure it out) dribbling its arctic cum down over the UK thanks to the late SSW. Such patterns give the UK the cloudiest, wettest coldest springs and summers possible. May God and his angels and archangels lend all possible divine assistance to break up the fucking boring pattern. NOW.

The area I've moved to, called waterthorpe, has so many awesome microclimates. I found a low woody field, surrounded by tall trees blocking the wind, but is also a suntrap. Even the air temp in here is a couple degrees higher than just 100 meters away. I should set up a weather station here...would be interesting to see the AVG. Maxes April - Sept. Prolly 2 degrees higher than the official station 5 miles away.

If you want to set up a weather station too far away for a normal PWS radio signal and you still want live data, I could send one of my cellular temp/humidity transmitters for you to test over the summer. As long as you can provide some kind of vertical pole or tree for it to mount to, there should be almost no setup required. |

Sounds like a cool idea! Perfect. It will take another week or two for some of the new parts I have on order to arrive, but when they do, I can put one together and ship it over. As long as you can find somewhere that gets a few hours of sun a day on average for the solar panel, it should work perfectly there. |

Well - better hope for a decent summer this year then for the sun hours lol. |

 "Climate scientists first laughed at a ‘bizarre’ campaign against the BoM – then came the harassment. For more than a decade, climate science deniers, rightwing politicians and sections of the Murdoch media have waged a campaign to undermine the legitimacy of the Bureau of Meteorology’s temperature records. Those records say Australia has warmed by 1.4C since 1910, the year when the bureau’s main quality-controlled climate dataset starts. Extremely hot days come along more often than they used to, and the warming trends are happening everywhere, at all times of the year. As a target for those with an often visceral distrust of the established science of human-caused global heating, the bureau’s temperature record might be seen as ground zero. “This has frankly been a concerted campaign,” says climate scientist Dr Ailie Gallant, of Monash University. “But this is not about genuine scepticism. It is harassment and blatant misinformation that has been perpetuated.” Despite multiple reviews, reports, advisory panels and peer-reviewed studies rejecting claims that its temperature record was biased or flawed, Gallant says the “harassment” of the bureau has continued. In the latest challenge, the Australian newspaper – which over the years has elevated claims from sceptics and bloggers on to its pages – is calling for a “proper, expert appraisal” of temperature records after running claims that mercury thermometers occasionally used by the bureau were recording lower temperatures at one location than newer automatic probes in the same place. One former executive, who for eight years was responsible for the bureau’s main climate record, says the constant criticism has affected the health of scientists over many years, who were diverted from real research to repeatedly answer the same questions." Well worth a read.... www.theguardian.com/science/2023/may/07/climate-scientists-first-laughed-at-a-bizarre-campaign-against-the-bom-then-came-the-harassment?fbclid=IwAR1EDh7vpP5YjgZm86fyJy7LEHTKuTB0M8fmNQpv9VPL0xUapees7WlQlLM |

Atmosphere Holding Back El Nino Outlook ( source: Weatherzone 0  Despite the ocean giving clear signs that El Niño could form later this year, a lack of feedback from the atmosphere is giving forecasters a reason to be cautious in their outlook. An abrupt period of warming across the equatorial Pacific Ocean has seen an El Niño-like pattern of sea-surface-temperature anomalies emerging in recent months. This transition can be seen clearly in the images below, which show cool surface water from the recent La Niña giving way to warmer water in the western Pacific over the last three months.   All international forecast models predict that warming will continue in the equatorial Pacific during the coming months, likely reaching levels that exceed the oceanic threshold for El Niño during the Southern Hemisphere’s winter. However, El Niño is a coupled ocean-and-atmosphere climate driver. This means the sky above the Pacific Ocean needs to respond to the ocean warming beneath it before a fully-fledged El Niño can be declared.  At this stage, the atmosphere is showing no signs of responding to the recent El Niño-like warming in the tropical Pacific Ocean. The Southern Oscialltion Index, which measures the atmospheric pressure difference between Tahiti and Darwin, needs to be consistently below -7 for El Niño. The latest 30-day SOI value was only -2.2, nowhere near the El Niño threshold.  The easterly trade winds that flow across the equatorial Pacific Ocean were also near-average in the past week. During El Niño, these trade winds would weaken or even reverse in direction. If the atmosphere continues to defy the ocean, the emerging El Niño could fizzle. But if the atmosphere becomes coupled with the ocean, there is potential for a strong El Niño later this year. To make matters more troublesome for long-range forecasters, the atmospheric component of El Niño can only be reliably predicted about two weeks in advance. Until the atmosphere starts responding to the oceanic warming in the Pacific Ocean, forecasters can’t do much more than sit tight and see what happens. Historically, forecast guidance usually starts to become more reliable as we move out of the Southern Hemisphere’s autumn and into winter, so a clearer picture should start to emerge in the coming weeks. If El Niño does develop this year, it will increase the likelihood of below-average rain and above-average daytime temperatures over large areas of Australia. It would also raise the odds of a below-average snow season in the Australian alps. We will continue to provide regular updates on the evolution of El Niño through the Weatherzone News page. |
