Winter storm update

Major late season winter storm still on track. Winter storm warnings remain posted for all of southwestern Quebec and extreme eastern Ontario. They are also in effect for all of New York and Vermont as well as most of New England. The leading edge of the snow is moving northeast across eastern Ontario and central New York towards Quebec at this hour with snow expected by 3 or 4am in Montreal. It will start light but become rather heavy towards the morning commute. Gusty northeast winds up to 50km/h will cause blowing snow. The snow will become light through the midday hours on Tuesday while a second area of low pressure begins to develop off the east coast near Delaware. Once this system begins to migrate towards Cape Cod, snow will once again become steady and heavy at times into Tuesday night. Total storm accumulations will range from 20 to 30cm in the St. Lawrence Valley and up to 50cm in the Townships and  across Vermont and New Hampshire. Temperatures will be cold for March around -2C with gusty winds.
