    Areas affected...much of Maine

    Concerning...Blizzard

    Valid 291545Z - 292145Z

    SUMMARY...Heavy blowing snow with rates of 2-3 in/hr is expected to
    develop across much of coastal and Downeast Maine through midday,
    and farther into the higher terrain later today.

    DISCUSSION...A rapidly deepening surface low will move northeastward
    toward Nova Scotia today, with intensifying large-scale lift north
    of the low across Maine and New Brunswick. Strengthening
    frontogenesis through a deep layer will lead to increasing snow
    rates with banding currently extending from Boston toward coastal
    Maine. As ascent increases within the favorable dendritic growth
    zone aloft, snow rates at or above 2 in/hr should be widespread, and
    3-4 in/hr may briefly occur as boundary layer temperatures range
    from the single digits well inland to teens near the coast.

    Forecast RAP soundings also indicate maximum boundary layer wind
    speeds above 40 kt, suggesting gusts of the same within the heavier precipitation bands.
