TUESDAY: SNOW AND RAIN BECOMES WIDESPREAD
A potent low pressure system will bring snow to Nova Scotia during the pre-dawn hours Tuesday and before trekking east to Cape Breton and P.E.I. through Tuesday morning. The snow will then switch over to rain for the southern coast of Nova Scotia.
Rainfall totals in Nova Scotia are expected to be heaviest along the southern shores, where many areas could get between 20 and 30 mm through Tuesday, particularly the southwestern portion. Much of the northern shores are expected to get 10-20 mm. Environment Canada has issued special weather statements across Nova Scotia warning of rain that could become heavy at times.
The highest accumulations of snow in the Maritimes will be in Cape Breton where 15 to 20 cm is possible. Extreme parts of southwestern New Brunswick could see 5-10 cm of snow.
By Tuesday evening the snow will have reached Newfoundland and will be at its heaviest. Accumulations of 20-40 cm of snow is expected for the Avalon. Coupled with strong winds of up to 90 km/h, it will create blizzard-like conditions with whiteouts for much of the southern and eastern areas including the Avalon.
Special weather statements have been issued by Environment Canada for the Avalon Peninsula, Burin Peninsula, St. John's, Clarenville and nearby areas.
Snow will continue until Wednesday morning, when it will change over to mixing.

LATE WEEK: ANOTHER STORM TO BRING MESSY WEATHER
The active pattern will bring another storm will into the region late Thursday through Friday night as a large system from the Atlantic tracks north into the Gulf of St. Lawrence with strong winds. While the exact track is still uncertain, a wide range of messy weather is expected for much of the region.
"At this point it looks like primarily rain (starting as snow and ice) for much of Newfoundland, but a swath of heavy snow with strong winds is expected for parts of the Maritimes," says Weather Network meteorologist Dr. Doug Gillham.
There may not be much of a break in the unsettled weather, as there is potential for another messy system to move in at the end of the weekend and into early next week as a Colorado low tracks into the region.
