    Here is my initial thinking for snow accumulations with the Maritimes storm coming Sunday through early Monday.

    Confidence is higher now with the idea that an intensifying storm center will track up into Nova Scotia later Sunday and Sunday night. Milder air being drawn in on easterly winds will lead to a mostly rain (rain or brief snow to rain) event for a majority of Nova Scotia & PEI, though once the storm center moves north of that latitude the cold air wrapping in behind the storm will change it back to snow with the potential for over 8 cm over western and far northern N.S. There could also be a narrow wedge or ice for a time over far northern N.S. and southern/eastern New Brunswick.

    Clearly, it looks like central and northern New Brunswick then up into the Gaspe will bear the brunt of this storm with snow becoming heavy later Sunday through Sunday night. As the winds pick up late Sunday night and early Monday there could be blizzard conditions.

    What will likely prevent this storm from dumping over 40 cm of snow will be that the storm will be moving along at a steady clip.

    For St. John's, NL, including all of the Avalon Peninsula this storm will initially start as snow Sunday afternoon and perhaps accumulate a few cm's before changing to rain.



    Looks like there is the potential for a sloppy (snow, ice, rain) storm across southern and eastern Ontario by Tuesday with snow farther north. I will elaborate further on this later in the weekend.
