The Winter Storm Watch that was issued for Moose Jaw and area has been upgraded to a Snowfall Warning as the track of the impending Colorado Low becomes clearer.

Environment and Climate Change Canada says that the rain falling in the Moose Jaw area will change to snow shortly after midnight tonight (Tuesday).

Models suggest that anywhere from 10-25 centimetres of snow could be on the ground by Thursday, with the heaviest snowfall occurring on Wednesday morning.

The snow, in conjunction with winds gusting as high as 60 km/h will produce localized blowing snow and reduced visibility on local roads and highways.

Meteorologist Justin Shelley explained that the storm is strengthening over Wyoming with it expected to touch down in Canada overnight on Tuesday.  

“The actual centre of the Colorado Low isn’t expected to move through southern Saskatchewan, the heaviest precipitation will be well north of the low and that will be centered over south-central Saskatchewan. It won’t be a direct hit by the low itself but will be from the snowfall.” 

Shelley is projecting that 15 to 25 centimetres of snow is expected to fall by Thursday.  

“The first part of the storm overnight tonight (Tuesday) into tomorrow morning (Wednesday) might get a little mix with rain and snow so it might not accumulate right away, however, once we get into tomorrow afternoon, we’ll really start to see the amounts pile up.” 

The bulk of the snow is expected to sweep through southeastern Saskatchewan and western Manitoba.  

Come Thursday, Moose Jaw residents will begin to see some improvements in the weather, as only some lingering flurries will occur.
