January 1916 was extremely snowy in parts of the western US. Independence, California recorded 75.7 inches of snow (192cm) which is by far their snowiest month ever. The long-term mean is 3.2 inches/8cm, with many recording zero. The average year only sees 5.21 inches/132mm rainfall. A desert climate still can see more snow in a month than me. Elevation is 3930'/1200m in a valley, not that far from Mt. Whitney, the tallest mountain in the western US.
US units Independence is in a desert valley, not that far from Mt. Whitney. Street view of the area. Records: Third wettest month overall.
Snowiest month ever, by far. The only other time they came close was in early December 1909 when they saw 31.7" of snow in five days (80.5cm).
Third coldest month (but January 1937 was a full 5.7F colder).
Second highest snow depth (December 1909).
No record low temp. 1937 was the only time they saw below -2F, but a few other years reached -2.

From a shoutbox discussion between me and Yahya Sinwar earlier tonight—March 1907 had some impressively warm temperatures in the eastern US. Fayetteville had its hottest day by 6°F for March:  Raleigh had snow earlier that month followed by three highs equal to, or above 90°F with that 94°F high being the hottest day by 2°F for March:  March 1907 was even more impressive in the southern Plains, especially in Oklahoma, with some stations seeing some of the earliest 100+°F highs on record.   |

102/37 is a ridiculous diurnal range. 39/3C at Gage Airport. The 102F reading is hotter than the record for April there. It reached 102 on March 19 and 20, then the next earliest 100F is May 4th. wrcc.dri.edu/cgi-bin/cliMAIN.pl?ok3407 |

Two Mays three years apart. The May 2018 average temperature was 17.6C, while the May 2015 absolute maximum temperature was 16.9C. may 2018  may 2015  |

Checking some stuff I have archived I came across this sheet with (very) old weather data. It’s interesting to see that Fahrenheit was used for temperature and inches were used both for air pressure and precipitation.
Columns 2 to 4 (“Barómetro”) show air pressure in inches, measured at various times of the day; columns 9 and 10 show daily minimum and maximum temperatures (“Temperatura del aire exterior”). Column 4 from the right shows precipitation (“agua caída”).
I know this is not exactly the point of this thread, but it’s nevertheless fascinating to see this prehistoric stuff. Not sure if there is a thread focused on very old data. There is nothing meteorologically impressive on there, but quite the opposite, and it’s rather nice to see that the data actually make sense.

This thread deserves a bump, just stumbled across it for the first time. March 2010 was a fucking epic month here, as it was both warmer than average and record wet. 5” of rain fell in a multi-day storm at the end of the month, and 3” of rain in a day early on, with plenty of nice warm sunny days interspersed. One of few months here to record over 10” of precipitation (all of it rain) and the only March to do so. March is already the wettest month on average here, and should be the wettest IMO, but the good, record warm Marches here tend to be very dry. Thus, one of my favorite months of all time here, as it’s mild and very wet, just as March should be.  |

A chilly late spring and early summer stretch in northeast Minnesota.
Snow at the end of May, and hard freezes most nights the first week of June.
Last spring freeze was June 21st (80/30), first fall freeze August 19th (72/27).
Is it bad data? The nights are extremely cold for the season but it's a known cold spot that recorded the only official -60F in the state. So I don't think so. Duluth is the closest major city. They averaged 59/41 (50.0 mean) compared to Tower's 67/33 (49.8 mean) in the same period. They only saw a trace of snowfall so it didn't stick. Temperatures were more stable there because the city is on the shore of Lake Superior (range of 87 to 33).
alex992 mentioned this place got into the teens in summer so I looked for the daily data. The June record of 18 looks possible, though it could maybe have been the 31st if the station is a day behind. The July record of 24 is possible (1997). It reached 26 and 27 many other years and the day was a 55/24 day that was cool at nearby places.
The August record is fake (1936). The day was 88/12. The second coldest is 21F on 1986-08-28, a 56/21 day that was cool at International falls at least.

February 2005 in Deniliquin, NSW Look at that difference in max temp from the 1st to the 2nd! This is probably the most impressive daily temperature drop I've come across. It's north of the divide too which makes it even more extraordinary. This was due to a strong low in the area which also produced the wettest day on record in Melbourne. It ended up being the coldest February there with an average max temp of 27.5C, well below the LTA of 32.1C.  |

Lots of precip and the cold air intrusions down in Cali was probably due to crazy jet suppression that month. It's actually happened a fair few times (more in the past) during long cold snaps further north. January 1916 was an icebox further north in the PNW, mostly dry but interspersed with a few moderate/heavy snowfalls and a a bit of rain associated with a fleeting warm up. |
