No doubt you caught the light show from Mother Nature Sunday evening. It’s not common for us to see a thunderstorm in early March, but it certainly isn’t out of the question, especially this year.
The lightening and thunder is often referred to “thundersnow” though there was little precipitation with this storm cloud, there was an abundance of energy. The storm developed along the edge of a frontal boundary as a warm front pushed through (notice how much warmer it is today) The warm air was forced to ride on top of the cooler air at the surface thanks to the snow pack on the ground. When you get that much friction in the atmosphere, sparks can fly.
There was some sleet and hail reported as the storm quickly pushed in from over Lake Superior inland north of the city. This video filmed by SaultOnline.com‘s Bruce Clement, shows the active weather at Trout Lake. The lightening show was seen all over the northern parts of the sky. Watch for the slo-mo footage toward the end of the clip.
