We managed to wash away all the snow from our first major blast of winter last week, but the white stuff could return in a big way this weekend.
That’s because a deepening low pressure system that will produce a lot of rain to begin with could turn to a big snow storm come Saturday, just in time for the arrival of Santa with the Rotary Santa Parade scheduled for Saturday night.
It’s a tricky forecast however because the storm track isn’t exactly known – so the Sault could see all rain, a mix of rain and snow or all snow – about 6 to 15cm by Sunday. Sault Ste. Marie appears to be positioned on the dividing line of rain and snow, if the track moves more north, we’ll see mostly rain, if the track dips to the south of us, we will see mainly snow.
Different forecast models haven’t pinpointed the exact track of the storm yet, some are calling for a big winter storm while others see us getting rain. One thing in agreement is a quick cooling trend developing for Thursday. (we could see some snow again by Thursday morning) The big story however is what will happen Saturday. Environment Canada as of Wednesday morning is forecasting a chance of rain Saturday and changing to snow Saturday night. Other forecasters see the system dumping as much as 15cm Saturday night followed by windy cold conditions and more lake-effect snows developing Sunday.
