We just can't shake the winter blues. The snow is melting, ever so slowly. The average temperatures are creeping up, ever so slowly, and lastly the sunshine is growing stronger. But that nasty morning chill just won't leave us. On Wednesday morning we managed a low of -10.6C (13F) here on L'Ile Perrot, well below the normal of -2C (28F). If we manage to squeeze out a plus 2 or 3C (36 to 38F) today for a high it will still be below the normal of 7C (45F). Such has been the case through the early portion of Spring 2015 in Montreal. High pressure will dominate today before the weather becomes very active Thursday and into the Easter holiday weekend.
SNOWSTORM?
A warm front will advance into southern Ontario and Quebec on Thursday into Friday with a period of light rain or even some spotty freezing rain followed by showers and very mild temperatures on Friday. We may see double digit highs on Friday of 10 to 14C (50 to 56F) across eastern Ontario and Quebec. Friday night a strong cold front will sweep the St. Lawrence Valley with rapidly dropping temperatures down to -4C (25F) by Saturday morning. At the same time low pressure will develop and move along that front south of Montreal spreading snow into the region. So after a warm high of 12 or 14 on Friday the temperature will plunge to well below freezing. At this time Saturday looks windy and cold with a high of only -3C (27F) and snow. Early estimates are for 5-10cm for southern Quebec but that amount could change either way depending on the eventual development and track of storm system.
