Significant precipitation expected Saturday and Sunday with both rain and snow possible.

A storm system moving through northern Manitoba this weekend will bring rain that will gradually change to snow beginning Saturday night into Sunday as colder air slumps into the region. Currently, the precipitation is generally expected to fall as rain, however much of the storm system will take place with temperatures just a couple degrees above freezing. If temperatures end up even a degree cooler, there is the potential that more of the precipitation could fall as snow, resulting in notable accumulations of heavy, wet snow across the region.

The most likely outcome will be 20 to 40 mm of rain with a few cm of snow possible as the precipitation weakens and tapers off on Sunday. Worst case scenario, if temperatures end up slightly colder, then 10 to 25 centimetres of heavy wet snow could fall in some areas; the main area of concern is a corridor that extends from Pukatawagan east through Nelson House, Thompson, and onwards to areas between Gillam and Oxford House.
