I wouldn't have thought that I prefer winter here in Aachen over Frankfurt. I have encountered multiple times now that it's sunny and breezy here while a foggy soup at home. It rains a lot here but days on end without sunshine are much rarer than in Hesse...
variable oceanic winters with nearby mountains >>> stable semi-continental winters
Intriguing, forgotten username mentioned how Brittany always had sun breaks during the winter while Northern Italy was perpetually covered in fog during the season. I'm not sure how true this difference holds in other regions like the Pacific NW, appears like places like Kelowna are actually gloomier than the immediate coast during winter, as 'semicontinental' central Europe is compared to truly 'oceanic' W Europe. Unsure why the coast tends to be sunnier despite often having more winter rain than the interior... Kelowna is a special case, though. The low sunshine is a combination of mountains on all sides + persistent temperature inversions creating cloud over the valley, making it the gloomiest place in Canada outside of Newfoundland. Similarly persistent winter temperature inversion patterns can be observed in Almaty and in Salt Lake City.

Unsure why the coast tends to be sunnier despite often having more winter rain than the interior... Parts of southern England had their wettest January on record in 2014 (up to three times more rain than normal, lots of flooding) yet had above average sun because the weather was so vigorous, i.e. they'd get a band of wind and rain, then a clear break for a few hours, then another lot of wind and rain, etc etc. Winters here are dull enough that a few hours here and there can still add up to enough to put us above average. The most overcast winter spells here are often completely dry, i.e. when we get an anticyclone stuck over us but the sun's too weak to burn the cloud off so it's just a blanket of grey. I've been to Germany in winter enough times to notice that there you get more dry but dull days when the weather is doing nothing, but I'm surprised anybody would notice the opposite just by going from Frankfurt to Aachen though.

I remember fæglèr complaining about stuck cloud and fog in the Willamette Valley of Oregon when he lived in Eugene; barely an inch of rain in February but very little sun. valley encouraged temperature inversion and low sun angle didn't help; maybe similar to the Po valley in winter. Northeast US except by the Great Lakes has too active winter weather to get stuck cloud with little precipitation frequently; more common in the spring even if spring has more sunshine by %

In November, Aachen has 40% more sunshine than Frankfurt on average, that's definitely noticeable although absolute numbers are low in both cities of course.

Weatherspark doesn't have data for Siri or Kish island. They did however have data for an island called Dalma. BRUH. Look at those heat indices! Compared to Abu Dhabi: And I wanted to compare them to Death Valley, but weatherspark doesn't have any data there, so I settled for the hottest (interpolated) place I could find which was Mulayjah. The fact that it's interpolated/extrapolated doesn't matter. Just wanted an example of a super hot desert climate.

Vardø at the eastern tip of the Varanger Peninsula, an island in the Barents Sea more than 70'N and 31'E. A tundra town as can be seen:
Kiberg in Vardø municipality is on the mainland peninsula but still pretty barren:
Then compare to Vadsø (70'N, 30E) only 54 km from Vardø as the crow flies. Seems more lush than I expected.
Sirkka farm in Vadsø
In between those two towns is the Arctic treeline. Surely one of the most abrupt natural divides in nature.

Now imagine 1877 or 1878 with an "average hottest day"—there are a lot more stations nowadays set in the outback, whilst many colder stations have been closed. Fraudulent tactics.

Utklippan in southern Sweden hasn't had a freeze since the 23rd of February! Only 17 days dipped below 0'C there this year with the coldest temperature being -2.3'C

Hoburg hasn't had a freeze this season either, and that station is at 57°N, but they did have multiple freezes in March and April, the latest being the 15th of April

14.3'C at both Sunndalsøra and Tafjord today was warmest. Åndalsnes 13.4'C. High of 9-10'C at the coast of Mid-Norway, up to 5'C at the North Cape.
Ålesund Dec 29th high/low: 11.6'C/9.7'C and mean 10.6'C.

Moscow must get artificial snow in mildest December since 1886 (not sure if recording started then):

They've got some new customisable time series graphs on our Met Office website which I've been playing around with just now: www.metoffice.gov.uk/research/climate/maps-and-data/uk-temperature-rainfall-and-sunshine-time-seriesGoing back to what I was saying in the 2019 summary thread about how sunshine is above average nearly every year now, I wondered if it was specific to my local site because they'd got rid of something obstructing the horizon at some point, but it turns out it's the same story right across the country. checked Northern Ireland / Wales / Scotland no recent trend. only exception is Scotland in spring. For England, the mean temperature (more the maximum than minimum) spring graph matches the sunshine rather closely. Doesn't look it at first glance; but the temperature graph has a different range than the sunshine one, peaks and troughs almost in exactly the same years

post-2003 heatwave to the mid 2010s had quite lousy summers in terms of sunshine too

NWS wrote an article on the largest Wisconsin weather events of the 2010's. Link: www.weather.gov/media/mkx/WCM/2010swisconsinevents.pdfTop 10:
1) I remember this. The snow was too deep for the little plow my parents had, so we had to wait for someone with a truck to plow us out the next day. A few windy days in the next few weeks covered it almost as deep as the original storm, but the snow was lighter and easier to move then.
Picture (not mine) of the storm. Probably in Racine, which is near Caledonia in the southeast corner that got over 18".
3) March had summer weather! That has never happened before, and hasn't come close since. March 14-22, an 9 day stretch, averaged 79.6/53.7F (26.4/12.0C) The hottest day was 83/58 (28/14C) and three days had 60F lows. The peak average in summer is 82/61. The average for this period is 44/26F (6/-3C). For another reference...the picture below was from Weather.com on 3/21/12. The daily record high for Sault Ste. Marie, MI was 57F/14C. The high in 2012 was 82F/28C. I think some places had daily lows that would have broken the previous record high.
I remember one day in May being way too hot for that time of year, then it barely rained at all in June and was hot in June and extremely hot in July. Fireworks for the holiday on the 4th were canceled due to fire risk. That's not unusual for people in drier areas, but wildfires are extremely rare here due to wet summers. Flooding is more likely.
4) 2013-2014 was cold and snowy. Awesome winter. 2014-2015 was good also. The news was showing pictures of icebergs on June 1st (I think) in Lake Superior in 2015.
7) Unfortunately the blizzard was in the northern half of the state. Milwaukee area got a few inches of extremely wet snow/ice/slush. However, April was near record cold and extremely snowy here, too. Several good storms and the snow didn't melt right away, either. I posted some pics in the spring 2018 thread (link coming... >>> cdweather.boards.net/post/49175)
8) Summer 2017 and 2018 both had flooding in southeast WI, but 2018 was more widespread. One or two observers recorded over 12" in one day in August 2018 just west of Madison, and the west side had major flooding damage. Some weather stations recorded over 20" in a month, when the average is 4 to 5". The Dane County picture is probably in Madison. The worst flooding was in rural communities near large rivers and lakes, as usual.
10) see above. Flooding has been an issue lately, not drought. The past 4 years have all been top 10 wettest, so lakes and rivers are high or very high.
