Waterloo Region will likely see 5 cm of snow on Saturday, followed by mixed precipitation Saturday night and further snow on Sunday, Environment Canada says.
A low-pressure system moving eastward over Lake Huron will collide with a second low-pressure front.
As a result, forecasters aren’t sure exactly what precipitation will fall on southern Ontario and which areas will be hit – but in general, Environment Canada expects snowfall to begin early Saturday morning, with more significant precipitation beginning in the late afternoon hours.
For Waterloo Region, that means snow off-and-on all day long, with 2 to 4 cm of ice pellets predicted to fall at night. Snow is expected to continue Sunday, although total accumulation is uncertain.
Temperatures will also warm up significantly under the storm’s path, with highs expected to approach the freezing mark particularly in areas from Waterloo Region west.
