Days after a messy mix of snow, freezing rain and rain coated roads across the region, Maritimers are being told to prepare for another winter blast.

CBC Meteorologist Kalin Mitchell said a low-pressure system from the mid-western U.S. is tracking towards the southern coast of Nova Scotia, and is expected to bring more snow mixed with ice pellets.

"Maritimes wide, as temperatures drop well below freezing Wednesday night into Thursday, icy road conditions will be a concern Wednesday night and Thursday," said Mitchell.

Similar to the storm that wreaked havoc on Halifax area roads over the last few days, this latest storm is bringing a mixed bag of precipitation. 

Mitchell said to expect about five to 10 centimetres of snow mixed with ice pellets around 3 a.m. or 4 a.m. Wednesday for much of mainland Nova Scotia. Later in the morning, that is expected to change to rain. 

Higher snowfall amounts are expected in the Annapolis Valley, Cape Breton, Hants, Cumberland and Colchester counties with Mitchell projecting between 10 and 20 centimetres. 

The Cobequid Pass could see as much as 25 centimetres of snow as the system passes over Nova Scotia. 

Later on Wednesday, strong winds from the north and northwest are expected to whip across Nova Scotia's north shore and Cape Breton with gusts up to 80 km/h, said Mitchell.

In New Brunswick, the heaviest of the snow will fall in the southeast of the province and up the Northumberland shoreline towards Miramichi with as much as 15 to 25 centimetres.

"Snowfall amounts in New Brunswick will taper towards the northwest of the province and along the Bay of Fundy coastline in the southwest mixing in of some ice pellets and freezing rain is likely," said Mitchell. 

Like New Brunswick, Prince Edward Island is expecting higher snowfall amounts in the range of 15 to 25 centimetres.  

"In the east of Prince Edward Island, Kings County, there is likely to be more mixing in of some ice pellets, maybe even a little rain.  Stronger north and northwest wind gusts will develop late Wednesday [with] gusts close to 80 km/h. So, blowing snow creating very poor visibility will be a concern," said Mitchell.

He recommends that travellers planning a flight Wednesday should check flight times before heading to the airport.
