.DISCUSSION...
KEY MESSAGE 1... Snow is expected to develop Sunday and
continue into Sunday night. Some travel difficulties are
expected.
KEY MESSAGE 1 DESCRIPTION...
Low pressure will track east from New York State Sunday and then
south of the Gulf of Maine during Sunday night. Snow is expected to
overspread the region Sunday morning and continue into Sunday night.
The greater snow accumulations will be across the Central Maine
Highlands, the Bangor region and all of coastal and interior
Downeast areas. Temperatures are expected to be in the lower 30s
Sunday and have adjusted snow ratios down a bit from NBM. Expecting
a general swath of 3 to 5 inches for much of the aforementioned
areas, although some locally higher amounts of around 6 inches will
be possible. Some travel impacts are expected Sunday into Sunday
night, especially for the Bangor region.
Snowfall amounts will decrease significantly north of the
Millinocket region. Across areas of far northern Aroostook County,
such as the Saint John Valley, will likely not see much, if any
measurable snowfall.
KEY MESSAGE 2...Low pressure to impact the region Thursday into
Friday with uncertain timing/track.
KEY MESSAGE 2 DESCRIPTION...
Low pressure should cross the region Thursday into Friday. However,
differences in the timing and track of the low still exist.
Precipitation types and totals Thursday into Friday will be
dependent on the eventual track and timing of the low. Current
indications would support precipitation in the form of snow
across northern areas. Snow, or a snow/rain mix, is possible
Downeast dependent on the eventual track. Based on the eventual
timing, the system could impact the region anytime from the
morning commute Thursday to the morning commute Friday.
