.DISCUSSION...
KEY MESSAGE 1...Snow moves in Friday night continuing into Saturday.
Minor snow accumulations over central areas will result in slick
travel Saturday morning.

KEY MESSAGE 1 DESCRIPTION...
Surface low will move thru the Great Lakes on Friday with overrunning
precipitation developing Friday evening. Low will ride along coastal
front in favored region of upper level jet. Categorical pops over
Downeast areas on Friday night with plenty of synoptic forcing
will bring qpf amounts of around 0.50 inches Friday night into Saturday
morning. Temps likely to be in the mid 30s over Downeast at onset
with a rain/snow mix occurring through the overnight, cutting
down on snow accums. QPF amounts will be lower further to the north
where temps are cold enough for all snow, bringing around 2-3 inches,
mainly from Houlton over to Katahdin. This likely to bring slippery
travel conditions late Friday night into Saturday morning.

KEY MESSAGE 2...Winter storm possible at the beginning of the week,
bringing travel impacts to portions of the area.

KEY MESSAGE 2 DESCRIPTION...
Another storm looks to be on tap for the region late in the weekend
into early next week. Deterministic guidance beginning to hint at
sfc low somewhere in the vicinity of Downeast or near the Gulf of
Maine Monday morning. Ensemble members are very gradually coming
into better agreement with a surface low somewhere near the Gulf
of Maine. Still too early to talk specifics but there are signs that
another storm will be impacting the region early in the week.
