The feisty Colorado Low inevitably set to move into Ontario will impact Quebec, the Maritimes and Newfoundland with mostly snow [of varying intensities], Wednesday PM into Thursday PM – lingering until Friday AM.
Snow and Ice
Beginning late Wednesday, snow will quickly spread across Quebec and bring alongside, heavy accumulating snow, particularly for the Northeastern Quebec Suburbs where 30cm or more could potentially fall. For Quebec City, 20-30cm is probable.
For New Brunswick, there will be a drastic and sharp transition line between heavy snow, freezing rain and rain. Currently, regions around the Bathurst region SW of a line to just south of Edmundston could receive significant freezing rain (10-15mm), thereby an inverse relationship will form: higher ice accretion, and lower snow accumulations. Elsewhere across New Brunswick, snowfall amounts will become significantly reduced the further south one travels (and higher probability of rain).
Across Newfoundland, light snow will encompass much of the province, however, there is reasonable certainty sea-effect enhancement will provide further snowfall for regions such as Corner Brook and Stephenville.
Nova Scotia, most of PEI, Cape Breton and parts of New Brunswick will experience rain. For most regions, the rain will be a non-factor, however, Southern and South-Central regions of New Brunswick, could receive 30-45mm of Rain, locally near 50mm.
Widespread gusty winds will be a noteworthy concern.
When will the cold relinquish?
As recently predicted and outlined in our Spring/Summer forecast, it is [and we expect] Spring to be relatively cool across much of Eastern Canada with above normal precipitation. However, we do believe more moderating temperatures will begin to enter the Eastern half of the country beginning very late April, and more prominently into early May.
Please stay tuned, as we at TCW are monitoring this situation attentively.
