A late season winter storm is poised to impact southern Manitoba Thursday morning through Friday.The highest concern with this system is the freezing rain risk along and south of the Transcanada highway corridor through southwestern Manitoba, and through the Red River Valley. There is some uncertainty with this system as to whether or not this freezing rain will be patchy in nature or if it will be a more organized area of freezing rain.Western and central Manitoba will likely see primarily snow, with accumulations of generally 4 to 8 cm. Some areas in higher terrain may see snowfall accumulations up to 15 cm.This statement may be expanded or upgraded to warnings as this system develops.###Please continue to monitor alerts and forecasts issued by Environment Canada.
