After entering the Northwest Territories, we encountered very high temperatures (certainly for this area in mid-August) and then a huge rain storm with pancake-size raindrops, sustained fork lightning and high winds. It was quite a display.
I tried to get a picture of a lightening fork, but missed on all my attempts.
My understanding is that the prairies and southern Northwest Territories are going to get a series of hot days followed by these intense storms, some of which may contain hail or may become tornadoes. Fingers crossed, we skip those.
I lived in Arizona while taking a lot of my flight training, so I became familiar with the amazing displays of lightening that can occur there.
I saw scenes like this, but was never able to catch one on camera. Photographer Mike Olbinski checked weather radar, packed up, drove to Apache Junction, and took this very impressive shot in the span of a ten-second exposure.
