Eastern Canada storm to impact Maritimes with high winds Thursday

An area of low pressure is forecast to develop into a strong storm as it moves from the northeastern U.S. into the St. Lawrence River Valley late Wednesday into Thursday.

An area of low pressure is forecast to develop into a strong storm as it moves from the northeastern U.S. into the St. Lawrence River Valley late Wednesday into Thursday. Caught between that storm to the west and high pressure to the east, the Maritime provinces are likely to contend with high winds.

It will be a cold night ahead for the region with low temperatures falling into a range of -4 C to -9 C except -10 C to -15 C in northern New Brunswick. Be cautious of any standing wet or slushy surfaces turning icy evening and night.

A round of light snow and rain is expected to move across the region on Tuesday. Little snow accumulation is expected for most parts of the Maritimes, but slippery spots should still be watched for as surfaces will be at and below freezing Tuesday morning. There is a higher chance of seeing snow totals approach five cm in parts of northern and western New Brunswick.

A Texas Low, which is a low-pressure system originating out of Texas, will swing up through the Eastern U.S. and into Quebec late Wednesday. Fuelled by the contrast between a fresh round of polar air breaking down into Ontario and milder air over the U.S. eastern seaboard, it will rapidly strengthen into a storm by early Thursday morning.

The Maritimes will then be squeezed between that storm system as it continues through Quebec and an area of high pressure over the North Atlantic. The pressure difference between those two systems will drive the strong expected wind.
