Heavy rain is forecast for this afternoon. The weather service issued warnings for persistent rain accumulating to 30..40 liters (1.2 ... 1.6 in) within six hours here; more than 100 liters (4 inches) further northeast in Pomerania along the Baltic Sea coast. Eventually we will get some weak thunderstorms first (a slowly developing crackle of cloud lightning with a slight rumble of thunder). The wind was blowing from the South for days, turned to the East now. All this moisture stems from the Mediterranean Sea whose water temperature is exceptionally warm this year. So, hopefully we will get back our regular westerly Atlantic stream soon with occasional light rain and long warm high pressure periods in between, that is, how 'normal summers' should be. |

How can you measure rain in liters? Isn't that a volume measure? So is it the amount that falls on a hectare? |

The weather service is more precise with words: "l/qm".... liters per square meter [l/m²] which is the same as millimeters [mm] per square meter. With millimeters you obviously don't need the area... so millimeters of rain divided by 25.4 gives inches. Don't know why but it is totally unusual here to specify amount of rain in millimeters; always "liters". |

Now that I've recovered from another wrecked weekend I'm just taking a short break from my veggies before I harvest a cabbage and a row of carrots. After an overcast 7C (felt like 4C) start we're now at a still overcast 11C (feels like 7C) with 14C expected before the falling wet stuff returns. My youngest daughter also had her baby giving me my 2nd grand daughter. Anyhow I better finish this coffee off before I finish up outside and then I can sit by the fire to enjoy a few beers. Cheers. |

When given as a length (height of column) the area drops out of the equation. Or are they trying to specify how much flows down a river? Or is it just a Germanic expression? |

Or is it just a Germanic expression?From a physical viewpoint you're right. But peculiar? Not at all... it's just the ordinary. ;-) It always was like this. Weather forecasts are given in liters [l/qm] only. I assume meteorologists today internally only use millimeters (international scientific cooperation) but for all their "products", that is, forecast maps, forecast texts or the TV weathermen they specify "liters" resp. "l/qm" as the measurement. Educated people know that "liters" equals "millimeters", at least, that's what I assume. Already in the 19th century meteorologist collected the water from raingauges and evaluated the amount with a measuring cylinder in millimeters (resp. precise to a fifth of a millimeter). If you talk about the climate here; e.g. if it's a rainy or a dry year then the accumulated precipitation over a month or year is often given in "millimeters"; but never for daily forecasts or reports. DWD (German Weather Service): current (text) forecast; In the text they just specify "l/qm". Nowhere "millimeters". Météo France specifies "millimeters", occasionally adding "liters per square meter" in parentheses. Example IMGW (Poland) just in "millimeters". Example. CHMI (Czech Rep.) also just millimeters. Example. Which is remarkable since the Czech Meteorological Service has its roots in 18th century Prague's Charles University (Prague's middle classes and aristocracy was German speaking back then; part of Holy Roman resp. Austrian-Hungarian Empire). An independent Czech nation (and standard language) didn't exist before 1919. KNMI (Netherlands): just millimeters Austrian Meteorological Service: just millimeters. Surprises me. I didn't know that. ORF (Austrian Public Broadcast): just millimeters. MeteoSchweiz (Switzerland): just millimeters. The Swiss are weird; no news... ;-) their vocabulary so different... from ours. Metrification reached Western parts of Germany with Napoleon's "liberation" crusade in 1810...15?; rest of continental Europe until the 1870s. I assume this liters vs. millimeters separation maybe exists at least since the formation of the modern (small) German nation state (without Austria and Switzerland). So, this is supposedly not a Germanic but a Prussian thing. They dominated Germany, including meteorologic research until 1918. The common German raingauge was invented by a Prussian meteorologist in the 19th century. |

Still in San Miguel Allende. Finding some fixers that will fit into my business plan. In the meantime, nights have been in the 50's. That is colder than I had expected, and the days are in the mid to high 70s. Today should top out at 78f. Today's focus is on houses on the outskirts of the city. If you can come visit. Just a few days ago, the city was voted as the number one destination for world travel. It has been named the "Best City in the World" multiple times by Travel + Leisure, and also received accolades from Condé Nast Traveler. These awards highlight its cultural richness, vibrant art scene, excellent restaurants, and walkability. My concern about crime is not evident. I do understand that there are cities to the west of her that are cartel strongholds. It's recommended that you don't visit those. Shootouts between rival cartels are not uncommon. But tourists are not a target. Competition is. |

We had quite some rain yesterday; about 40 l/m² (1.6 in). Sufficient to flood the railway underpass, blocking all traffic; the first time in many years. There must be some hidden pumping station that drains the water. But this takes up to half an hour. Streetcars stopped in front of the new lake creating a traffic jam. Some impatient 4WD and SUV drivers, of course, have to squeeze past... think it's a good idea to test how to create the largest tidal waves in knee-deep water... |

After a damp 7C (felt like 5C) start then a soggy trip into town to see the quack again followed by a soggy trip out to Inverell and back the temp here has reached the 11C mark (feels like 8C), but our expected 13C max for today is looking like a bridge too far. Now I most certainly do need a spinal reset. Cheers. |

We made it to a cloudy 23C today. Not bad at all. With each crime and every kindness we birth our future. |

The weather here is delightful. Currently, it is 79°F, and the lows have been in the mid-50s. My kind of weather. It's a little cloudy, but that saves me from having to wear a hat all day. I am really liking this city. Found some mountain hot springs earlier. Still going to Guanajuato tomorrow. It's the state capital and a UNESCO World Heritage site. Founded by the Spanish in the early 16th century, Guanajuato became the world's leading silver-extraction centre in the 18th century. It's been a while since I visited that city. I really should have brought my Conquestor Helmet. |

I'm glad that you're enjoying yourself there Carlos. After getting 13.75mm on us yesterday today got off to a very frosty -1C (felt like -4C) start with a sunny 12C being expected, but that wind is cutting. Anyhow I've pretty much caught up with my delayed Monday chores and I'm just running come new bed linen and shirts through the washing machine and as soon as I've got them out on the line it's off up to the chemist for a new pill that the quack added to my list of them. I'll certainly need a beer after all that. Cheers. |

Time to pack again. The weather in Guanajuato is currently 59°F / 15 °C with a high of 81°F /27 °C today. Looks like I will have rain again this time, Saturday, Sunday, and Monday. What happened to summer? It was supposed to be 90-100. |

We made it to a cloudy 26C today, so no A/C required. The beer tastes not bad anyways. With each crime and every kindness we birth our future. |

Anybody want to trade some of your cool and/or damp weather with me for some hot Texas weather? The dog days of Summer 2025 finally arrived here in the Dallas-Fort Worth Texas area with our first official 100 F (37.78 C) degrees temperature and it's here to stay for a while they say. Right now at 9:25 pm in the evening, it's only 86 F (30 C) with an expected low overnight of around 76 (24.44 C). |

Well here it was a very frosty -3C (felt like -7C) this morning and it's now 13C (feels like 10C) so we're likely to hit our expected max of 14C today, will that do you? Though tomorrow should be cooler and very wet again. After 4hrs of metalworking downstairs under the red hot gaze of Robbie the Robot I've had enough so I'm now upstairs where it's much cooler with a beer in hand (21C upstairs and 30C now downstairs). Cheers. |

This Oklahoma heat is not any better. The heat index is 37°C plus all this week. I overdid outside it last Sunday and paid the price for it. A hour and a half of weed eating in the heat then retreated to the a/c. A half glass of cool water and then about 15 minutes later in the bathroom with dry heaves while having to sit down at the same time. That is something I don’t want to wish anyone. Wiggo, I’d be happy to have some of your cold weather here.

Anybody want to trade some of your cool and/or damp weather with me for some hot Texas weather?Yes, I want to... immediately. We have another week of dull, completely overcast weather ahead of us here in eastern Germany. 21°C (70F) in the afternoon, maybe two days reaching 23°C (73F). Air condition? Pah.... I grabbed a fleece jacket this morning to prevent a summer flu. I want summer, now. It's the end of July, after all. And the long dark 'winter' isn't far, that is, the eternal grey autumn which lasts until next spring... The dog days of Summer 2025 finally arrived here [...]Thanks for this interesting link. We have this term in German too: "Hundstage" (Hund... dog, tage... days) |
