- Australian heatwave expected to continue next week with record temp of 50.7 °C (124 deg F) under threat.
- Parts of Russia plunged towards -60 °C on Saturday -76 deg F
- Snow-covered highways, near-zero visibility and a bone-chilling cold wave hits part of Canada
- Temperatures to plummet to - 40 degrees Fahrenheit (-40 deg C) in the U.S.
On Wednesday and Thursday, new maximum temperature records were set at 27 sites across NSW and the ACT, while some of the hottest overnight temperatures on record worsened the impact of the ongoing hot spell.
According to the Sydney Morning Herald, Walcha Council will use water from the Yarrowitch River in water carts to cool the bitumen pavement which is currently melting due to the extreme heat.
Meanwhile, Severe Weather Europe reported parts of Russia plunged towards -60 °C on Saturday night, while parts of Australia are in the middle of the summer and the unprecedented strong heat wave have seen temperatures approaching 50 °C. Yesterday, the difference between the two areas was over 100 °C! 212 deg F.
Temperatures plunged down to -57.5 °C (-75 deg F) in Delyankir (Oykmyakonski District, Sakha Republic) in far eastern Russia last night.
This part of Russia is one of the coldest places on Earth and the coldest inhabited area – the (fairly) nearby Oymyakon holds the official lowest recorded temperature in the northern hemisphere: -67.7 °C on February 6, 1933.
Meanwhile, parts of Australia have been undergoing a scorching heat wave.
Yesterday temperatures peaked at a blistering 48.3 °C (119 deg F) at Tibooburra Airport (NSW), while a number of stations recorded peak temperatures above 45 °C.
The official highest temperature in Australia recorded so far was 50.7 °C in Oodnadatta on January 2, 1960.
Meanwhile, winter threw everything it had at Montrealers on Sunday, from 23 centimetres of snow to wind to sub-zero temperatures that felt like -31deg F, -35 deg C with the wind chill.
By late Sunday afternoon, the snow had lightened up in Montreal and the wind dropped from peak gusts of 70 km/h earlier in the day.
Total snow accumulation was 23 cm, with some more expected overnight.
And as the wind kicked up at about 9 a.m., blowing snow was added to the mix.
Sunday was marked by delayed and cancelled flights, snow-covered highways, near-zero visibility and bone-chilling cold.
"In my 20 years of working as a professional meteorologist, I don't remember any weather pattern like that," said Environment Canada's Alexandre Parent.
Three provincial ministers issued a joint statement alerting citizens to the frostbite risk.
Parent said the combination of snow, cold and wind rarely happens in Quebec since temperatures usually go up when it snows.
"To have a combination of a snowstorm with significant amounts of snow - we're talking about 20 to 25 cm with this winter storm - and to have really cold temperatures - in Montreal, we stand at minus 18 - that's really what stands out," he said.
AccuWeather says a polar plunge of brutal cold has descended on the northeastern United States, which can threaten lives and complicate travel and cleanup efforts following the weekend snowstorm. Even the areas that escaped snow or ice this past weekend will be shivering in the Northeast as brutal cold plunges in from the Midwest.
"In some cases, temperatures may plummet 40 degrees Fahrenheit (-40 deg C) from their highest levels over the weekend to their lowest levels," according to AccuWeather Senior Meteorologist Alex Sosnowski.
