Ottawa weather: ‘Significant snowfall’ expected on Wednesday


Ottawa is bracing for another significant snowfall that is expected to begin late Wednesday afternoon and bring up to 20 centimetres of snow to the region.


A snowfall warning is in effect. Environment Canada is calling for snowfall amounts of 15 to 20 centimetres. The storm is expected to begin late afternoon and end Thursday afternoon.


The weather agency is warning of possible reduced visibility in heavy snow and says rapidly accumulating snow will make travel difficult. Isolated power outages are also possible.


The snow is expected to begin as a Texas low moves into the area.


“Be prepared to adjust your driving with changing road conditions,” Environment Canada says. “Prepare for quickly changing and deteriorating travel conditions. Visibility may be suddenly reduced at times in heavy snow.”


The storm is part of a system that is expect to affect a large swath of the population between Windsor and Ottawa. 


Ottawa has received about 42 cm of snow so far in January.


Tuesday’s forecast calls for flurries ending near noon and a high of 1 C. The wind chill will make it feel more like -7 this morning. There will be a 60 per cent chance of flurries for the remainder of the day. 


Temperatures will fall to -11 C overnight, and the wind chill will make it feel more like -13.


It will be mainly cloudy on Wednesday before the snow begins late afternoon. The high will be -7 C, with wind chill values near -15.  


Wednesday’s overnight low will be -6 C.


On Thursday – periods of snow and a high of -3 C. The snow will end Thursday evening and temperatures will drop to -16 C overnight.
