The weather is expected to do an abrupt about face today as we plunge back into the freezing temperatures.
Environment Canada has put out a snowfall warning for all of Niagara and Hamilton as a cold front moves across southern Ontario this morning.
The front is expected to stall over the lower Great Lakes, meaning we could see 10 cm or more through the day today.
Snowfall is expected to start this morning, getting heavier by the afternoon, and eventually tapering off overnight.
Motorists are being warned to prepare for a potentially challenging drive home tonight.
