The Swedish Meteorological and Hydrological Institute (SMHI) Thursday reported a new national high temperature for February — 16.8 degrees Celsius.

Record temperatures were also reported Thursday in Poland where Makow Podhalanski hit 21.7 degrees Celsius, and in Slovakia, where the southwestern city of Hurbanovo reported a high of 20.8 Celsius.

Thursday’s records come as western and central Europe is seeing something of a winter heat wave, with records falling earlier in the week in the Czech Republic, Austria, and in Germany, where on Monday, Hamburg hit 21.1 degrees Celsius — the warmest temperature recorded there in any winter month.

Some of the records that fell this week had stood for more than a century.

The heat wave comes two weeks after western and central Europe saw a frigid blast of winter, with heavy snowfalls in Britain, Germany and the Netherlands.

Washington Post meteorologist Matthew Cappucci says the region has seen the wild swing in temperatures thanks to a seesaw effect in the jet stream that earlier in the month brought freezing air down from the pole, and this week brought warm air from the south, including dust from the Sahara Desert in Africa.

Any idea what size it was, sounds like it was substantial, maybe f3/4?

Looks like a violent enough tornado. They should be doing the initial damage surveys this afternoon. One of the tornados struck James Spann's house while he was doing the weather coverage of it

"Cloud avalanche" in Nepal, pretty cool, music background is a bit naff but worth a look all the same.

Freak late snowfalls in parts of Ontario, Canada. Toronto airport (CYYZ) measured 0.2 cm with a rainfall of 15 mm on 28th, daily max temp only 9 C. This snow is the latest measured snowfall in that location edging out May 26-27 1961 overnight.

The downtown location no longer specifies snow amounts and public video reports suggest trace amounts fell there. It would be the fifth latest trace of snow since reporting began in 1840. (only since 2017 has there been this absence of definite snow reports but I maintain a data base from indirect clues such as snow on ground and nearby reports). The latest traces of snow at the downtown location were 3 June 1859 and 1 June 1945, also late May traces in several years. The latest measurable snowfall at the downtown location remains 16 May (1884). The max of 11 C for the 28th and the min of 3 C are both near record values, and if it fell lower by morning of 29th (today) I will add the details. Due to the urban heat island that has developed since most cold records were set in the 1840-1890 period, daily record lows are unusual at Toronto downtown nowadays but one was set last year on 9th of May.

Most snow events in this region in May involve a cold rain that has snow mixing in occasionally, with a trend towards sticking snow on the higher ground west to northwest of the city. Elevations near Lake Ontario are only about 70-80 metres above sea level, but rise above 200 metres to the west of the Niagara Escarpment (the rock cliff that Niagara Falls cut into since the glacial era). There were video confirmed reports of 1-3 cm accumulations in the "highland" region northwest of Orangeville, ON specifically around Dundalk which is about 500 metres above sea level.

It had been a warmer than average May to the 27th (this will cut in) and at the airport the high on the 25th was 33.3 C, so the temperature fell from that point more or less continuously until the snow and 3-4 C readings arrived.

The snowfall was part of a larger rainfall event associated with low pressure tracking east-northeast through PA and NY states. It is therefore a somewhat similar event to the freak June 1816 inland New England snowfall from a coastal low. It also looked fairly similar to the reconstructed weather map for 3 June 1859 and some other late spring snow producers of the past.
