Southern Ontario derecho of May 21, 2022: an ECCC perspective - Peter Kimbell

CMOS Ottawa Centre Talks – Peter Kimbell - Four years after the National Capital Region tornado outbreak of September 21, 2018, another summer convective storm affected southern Ontario (including the NCR) on May 21, 2022. This time, while the Northern Tornadoes Project did diagnose a few tornadoes, the storm’s primary manifestation was not tornadic. Rather, a linear convective system developed over southwestern Ontario, and maintained its linear characteristics throughout its trajectory across southeastern Ontario, the NCR, and into southern Quebec north of Montreal. Many people in Ontario and Quebec suddenly became familiar with the word “derecho,” which is Spanish for “straight ahead.” The speaker talks about derechos, including climatology, differences with tornadoes, and more.
