According to Environment Canada Meteorologist Gerald Cheng, Waterloo Region will be seeing a sharp drop in temperatures Monday evening as an arctic blast of wind makes its way through.
Cheng says the temperature drop was "almost record-breaking, but not quite", but was "still unusual because it's certainly not the seasonal temperature."
Seasonal norms for this time of year stand at around 5 degrees for daytime highs with -2 for nighttime lows. Instead it's a windchill of -3 this evening, dropping even further to -10 overnight.
Flurries are expected late into the evening with 2 to 4 cm of snow. That continues into the Tuesday morning with few flurries during the day, but mostly cloudy otherwise.
According to Cheng, the rest of the week will remain chilly, but would rise up to seasonal norms by the weekend.
"After that it seems like we're going to close out November with normal temperature," Cheng said.
