Extreme cooldown after the 2nd heatwave in the northeastern USA hit not only Boston /https://mkweather.com/boston-reached-100f-38c-in-june-the-3rd-time-in-history-then-record-cooldown-to-57f-139c//, but temperature records were measured in other parts of the region.
Concord, New Hampshire recorded on Saturday, 3. July very cold day, with a daily maximum temperature of only +15°C / 59°F, which was the coldest 3. July since 1914 (in 107 years).
The next heatwave is for the Northeast forecasted only between 16.-22. July 2021, until then, neutral or colder times are waiting for one of the most populated regions in the USA.
The most of time until 22. July 2021, the West in the USA will be very hot, while Midwest or Southeast will observe cold conditions.
Colder conditions in the Eastern half of the USA in the next period are partially associated with Hurricane Elsa, which already hit Florida, and the first report after the direct impact of the hurricane will be a topic of one of the next Mkweather article /https://mkweather.com/hurricane-watch-in-florida-elsa-comes-already-in-the-next-hours-then-hits-all-east-coast//.
Meanwhile, in Vancouver, Seattle, Portland, San Francisco, and the LA region, the next heat dome is building and the heatwave in Canada will be shifting until the end of the week towards Hudson Bay, Manitoba, Nunavut, and Ontario /https://mkweather.com/canada-hits-the-next-heatwave-trees-drop-leaves-prematurely//.
