Environment Canada has issued a snowfall warning for most of New Brunswick for 15 to 20 centimetres of snow. Rain or snow will begin Thursday evening and develop into mostly snow overnight.

The snowfall warnings are in effect for Campbellton, Bathurst, Fredericton, St. Stephen, Moncton, the Acadian Penninsula and the eastern coast.

The Saint John region has a special weather statement in effect, calling for up to 10 centimetres of snow. Edmundston has no special weather statements.

Ryan Snodden, a CBC meteorologist, said the storm will have an impact by Friday morning.

"Through Friday, we're going to be tapering from snow back to flurries, but that Friday morning commute is going to be a very slow-going one," Snoddon said, during his Thursday evening forecast.

"Slick, snowy, slushy, we could use all of the terms, but the main story is that it's going to take you longer to get to where you need to be tomorrow morning," he said, adding that drivers without winter tires on should take extra care.

Low temperatures across New Brunswick overnight Thursday will hover around 0 or 1 C, Snoddon said.
