   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.
