Forecast as of 8:30 am:
Remaining cold but fair into Monday afternoon. However, a strong weather system soon comes along towards Monday evening into Tuesday, bringing strengthening winds, snow and then a wintry mix. There is 3-5 hrs worth of snow expected from late afternoon Monday into the evening before changing over to ice pellets then freezing rain Monday night into Tuesday. Models still have poor agreement in this marginal situation so confidence on accumulations is low. Some have freezing rain and ice mixing in quicker, while at the other extreme the worst case scenario would be 10-15cm (suggested by Environment Canada Winter Storm Watch). However, the best estimate at the moment is for a general 5-9cm before ice pellets mix in to hinder accumulations. After midnight freezing rain likely becomes more significant (trace to 2mm possible) before changing to rain late in the night and into Tuesday. Rain will last though Tuesday morning but ease, clearing for the afternoon. Winds will gust 70-75km/h overnight, gradually easing Tuesday.
