Wintry Week Ahead

From ctv.ca Crews clear Halifax streets from more than 30cm of wet snow.

Kemptville, Eastern Ontario and Western Quebec remained sandwiched between weather systems this past weekend with heavy lake snows to our west and the first big coastal snowstorm for the Atlantic coast to our east. Many towns in the maritimes including Halifax had close to 30cm of wind driven heavy wet snow from a nor'easter over the weekend. Roads were closed and the disturbing pattern of drivers being stranded in there cars so far this winter season continued. Road crews were slow to respond and numerous drivers had to spend a long night trapped in their cars. The same scenario had played out along the 402 in Ontario late last week, but by all accounts that situation was caused by unprecedented snowfall rates and not poor plowing.

This week we are awaiting low pressure that is getting organized in the Ohio valley. The storm is expected to intensify as it moves to lie near Brockville by Wednesday. It will be a slow moving system with precipitation and wind occurring from late today into Thursday morning. Early indications are that close to an inch of precipitation will occur with this storm. It translates into 10-20cm of wet snow for most areas with more rain than snow along the St. Lawrence River and Lake Ontario. The precipitation with this storm will be very elevation and temperature dependant with lots of mild air accompanying the storm. Expect very changeable weather and road conditions, plan to drive slowly this week and adjust your speed and distance.
Snow forecast:
Kemptville: 5-10cm
Brockville: 5cm
Ottawa & The Valley: 10-20cm
Montreal: 5cm
