widespread totals in excess of a foot across northern and central
maine into parts of interior downeast maine.  Amounts dropped off to
3 to 6 inches along the coast.  Another storm on the 20th produced
from 8 to 12 inches of snow across much of northern and central
maine.  A blizzard on the 26th into the 27th affected mainly
Washington and coastal Hancock counties. A winter storm on the
30th produced from 4 to 12 inches of snow across northern and
central maine.  Another event on the 31st produced up to 8 inches of
snow in parts of Washington county with one to two inches of sleet

wind speed for the month at Caribou was 43 mph on the 27th.  The peak
wind speed at Bangor this past March was 53 mph on the 26th.

The outlook from the climate prediction center indicates an
increased likelihood of below normal temperatures across western
Maine, and no strong climate signals that would point toward an
unusually cold or warm april across eastern Maine.  There are no
strong climate signals that would tilt the odds towards an unusually
cold or mild April. Daylight increases steadily with over an hour
and a half gain in daylight during the month of April.
