Special Weather Statements Issued – A Christmas Storm Is On The Way

Environment Canada has issued two different special weather statements in advance of the Christmas holidays that will produce lots of moisture. Some areas could see up to 15cm of snow, while other areas will get a lot of rain, preceding a smaller snowfall. Here are the details:

Rain developing tonight followed by potentially heavy snow Christmas eve into Christmas Day. Rain is forecast to begin tonight ahead of an approaching low pressure system. As the low pressure system lifts northward Thursday, the rain is forecast to transition over to snow. The snow may become mixed with ice pellets or freezing rain for a period Thursday or Thursday night. By Christmas Day, the snow may become heavy at times, resulting in difficult travel conditions.
Snowfall accumulations in the 5 to 15 cm range will be possible Christmas Eve through Christmas Day. Snowfall Warnings may be required at a later time. There remains considerable uncertainty as to the exact track of the low pressure system responsible for the rain and snow. This will ultimately affect how much snow may fall at a particular location.

Potentially heavy rain followed by snow for Christmas. Rain is forecast to begin tonight ahead of an approaching low pressure system. This rain will then continue into Thursday and become heavy at times. Total rainfall amounts of 15 to 25 mm appear likely.
By Thursday evening or Thursday night, the rain is expected to change over to snow after the passage of a strong cold front. A few centimetres of snowfall accumulation will be possible Thursday night through Friday morning. There remains considerable uncertainty as to the exact track of this low pressure system and the timing of the changeover from rain to snow. This will ultimately affect how much snow may fall at any particular location. Motorists should be prepared for deteriorating winter driving conditions in areas that receive snow Christmas eve into Christmas Day.
