As we informed in last days, while parts of central and eastern USA hits powerful Arctic blast in next period, western coast of the USA and Canada stays extremely hot.
While e.g. New England, Northeast or Colorado and Wyoming, Rocky Mountains region reports unseasonably strong blizzard at the weekend (17.-18. April 2021), California, Oregon, Washington state, British Columbia, southern Yukon and southern Alaska experience with extremely warm April weather, in southwestern Canada with summer temperatures above +25°C.
The hottest was on Saturday, 17. April in Lytton, approximately 265 km from the city of Vancouver, +28,3°C / 82.9°F, what is the highest temperature in Canada in 2021 so far.
Powerful heatwave is coming after extremely cold first half of the month in Alaska and Yukon, where temperatures dropped up to -42,7°C / -45°F /https://mkweather.com/extremely-cold-air-from-alaska-will-shift-above-the-usa-late-frosts-and-snowing-in-outlook//.
Many parts of the USA and Canada experienced with powerful heatwave during the first half of April 2021 and tornado outbreaks have ocurred last month mainly in Southeast, too /https://mkweather.com/gigantic-hailstorms-and-deadly-tornadoes-in-the-usa-again-forecasts-see-2-next-outbreaks/; https://mkweather.com/usa-406c-canada-281c-north-american-heatwave-hit-in-full-power-extreme//
Now, late frosts should destroy harvest in many parts of central and eastern USA, but hot weather should offer for inhabitants of the west of continent good weather for outdoor activities.
