Snow moving in this weekend.. colder next week
After an extended period of mild and snowfree weather, it looks like southern MB will finally be seeing some snow this weekend. A complex storm system will develop to the lee of the American Rockies Friday and begin to affect the eastern Prairies into the weekend. The storm system will initially spawn a low over Montana that will spread snow over southern SK and southwest MB Friday into Friday night. This low is expected to weaken by Saturday, as the main energy is transferred to a more intense Colorado low that will track into Minnesota over the weekend. This low will bring snow to much of southern MB Saturday into Sunday, with amounts of 5-15 cm possible, with heavier amounts likely south of the border. The snowfall may be mixed with freezing rain or ice pellets on Saturday over the RRV and southeast MB as warmer air aloft feeds into the system. By Sunday, increasing northerly winds on the backside of the storm will bring colder temperatures over southern MB along with snow and areas of blowing snow. In the wake of the storm, colder and drier weather is expected Monday through next week as Arctic air pushes back into southern MB for the first time in two weeks.
