Feel free to share any weather map that gives you a hard-on. I'll start with the so-called "Beast from the East" back in Feb-Mar 2018. Utter shite at ground level, but boy did the airmass maps look beautiful.   And here's the "Schneekatastrophe" of NYE 1978. Nice cold front there, with 0°C over southern Germany/Poland and -20°C over northern Germany/Poland.   This probably was one of the coldest airmasses of the century in my neck of the woods.   Same shit 10 days later:   That month in central Marseille, 1 km from the Vieux Port and the Med. A -8°C high the first time, then a -10°C high on the second round: www.infoclimat.fr/climatologie-mensuelle/STAICA31/fevrier/1956/marseille-observatoire-longchamp.htmlAnd in summer... Blob of 28°C 850 hPa temps over SW France. Twas the time when the country beat its all-time record @ 46°C.   |

29 July 2010, the day we broke the all-time heat record (37.2C) in Finland:
14 October 2018, the day we broke the all-time October record of 21.1C, at 65N, in Oulu:
24 December 2010, 3rd coldest Chrismas Eve on record in Southern Finland. A low of -22.4C was recorded at Helsinki Kaisaniemi:

AJ1013 Unfortunately Meteociel has only eastern Atlantic + Europe or northern hemisphere maps. No map zoomed in on north America AFAIK. Also their color scale is adapted to western Europe. The 850 hPa temps Canada sees when the polar vortex sits over there would be off the charts.

Some good setups for North America July 22nd, 1952 (the day where the all-time record high was reached here; see this for more info on record highs which were broken):  July 1st, 2012 In addition to the heat and humidity (temperatures reached 100°F in places that day combined with dew points above 80°F in much of the coastal Carolinas), the atmosphere was also very unstable, with very large negative values of the lifting index + very high CAPE values, making for the perfect conditions for severe t-storms.  May 29th, 2019 The Memorial Day heat wave (nicknamed the "Death Ridge"), had 8 consecutive days with highs above 90°F, with Wilmington reaching 101°F on May 29th (the peak of the heat wave), a new record high for May, with New Bern coming 1°F short of the May record at 99°F.  |

I'll do Europe for now. ---------------------------------------------------------------------------------------------------- Some which come to mind for Europe: August 10th, 1999 One of the highest 850 hPa temperatures recorded in Europe; some unofficial stations within Sicily have seen temperatures as high as 119°F. June 25th, 2007 Stations within the Med. have seen triple-digit highs; Athens had record 115.2°F the next day, and downtown sites in Palermo, thanks to a foehn effect, have seen lows up to 96.8°F (!). August 3rd, 2017 Although 850 hPa temperatures aren't as intense, though the August 2017 heat wave made for some sustained heat, with Rome seeing 10 consecutive days above 95°F highs. All disgusting days here. |

If it weren't for North Sea surface flows on this day, this setup would have annihilated the all time record. In the end the day reached 34c, and the record was equalled a month later.  |

Had this type of setup been shifted east, and the heat were centered over Italy, Rome would've easily tied or broken its all-time record (i.e. it would've easily reached 105°F or so) with those 850 hPa temperatures. |

London would have been looking at above 40c with ideal winds. |

London would have been looking at above 40c with ideal winds. Even Paris didn't reach 35°C due to shitty NE surface winds. Meanwhile the Med was baking in the mid-40s. |

The beginnings of the epic month that was January 2019. The epic stretch of weather began after the 10th of Jan.  |

Not so much a chart, but a forecast from a couple of years ago that I found cool. Really shows those valley frost hollows at work.  |

Weather map from a hailstorm in July 1788. It is said to have contributed to the French revolution the year after due to huge crop losses over large areas. The two bands are where hail destroyed crops. By 8:30 am the storms were above Paris and by 2:30 pm above Utrecht.  |
