A Colorado Low is on course to impact Southern Saskatchewan and Manitoba as the week draws to a close, promising significant snowfall and challenging weather conditions across the regions.

The journey of the Colorado Low northwards brings the first round of snow to Saskatchewan from the south, beginning overnight Tuesday and carrying on into Wednesday morning. The main band of snow is expected to catch up by late Wednesday morning. Along the American border in the southeast of the province, there may be a bit of mixing due to slightly warmer temperatures.

The snow is set to continue unabated through Thursday, beginning to dissipate from west to east Thursday afternoon and concluding entirely by the end of the day. The heaviest snowfall is anticipated in the Southwest and West Central regions, where a broad swath could see accumulations of 10-20cm. This 10-20cm zone also extends into Southeast Saskatchewan, covering a significant portion of the province with a hefty blanket of snow.

The influence of the Colorado Low extends into Manitoba by Wednesday evening, with snow initiating in the southwest and gradually expanding northward throughout the night. By Thursday morning, the snow could intensify, particularly in the Parkland and Westman Regions, where it may fall heavily at times. The storm is expected to exit the region late Friday evening.

A widespread accumulation of 10-20cm is forecasted across Southern Manitoba. However, in the Red River Valley and the Eastman Region, snowfall totals are predicted to be less than 10cm. This is due to mixing with rain as temperatures hover just above the freezing mark, limiting the accumulation of snow in these areas.
