.DISCUSSION...
KEY MESSAGE 1...Light Wintry mix north, rain south tapers to
rain showers/drizzle areawide this afternoon. Another round of
rain south this evening with refreeze likely areawide tonight.

KEY MESSAGE 1 DESCRIPTION...
Challenging forecast this morning with large dew point
depressions across Northern Maine delaying precipitation onset.
Light snow is now falling at most locations except the St. John
Valley but will be underway shortly. A warm front is lifting
north across the Downeast at this hour. A weak surface low is
tracking out of southern Quebec towards Maine within an open
500mb weak shortwave. The low will track across northern Maine
today drawing warmer air northward across the forecast area with
precipitation changing to rain areawide. Expecting 1-2 inches of
snow from the Baxter Region northward with the highest totals
in the St. John Valley, cannot rule out 2-3 inches. Hi-res
modeled soundings suggest with the low tracking overhead the
Central Highlands from Bangor region northward to southern
Aroostook the possibility of some drizzle. The winds will be
very light aloft above the surface in the lowest 2kft,
saturated profiles and given this is a southerly upslope cannot
rule out some patchy fog/drizzle.

The first low exits across the Maritimes this evening as a
second low tracks into the Gulf of Maine from Southern New
England. This will begin drawing a cold front south across the
forecast area. Expecting another round of light rain to develop
across the Central Highlands, Bangor Region and Downeast Maine
with rain showers north of there transitioning back to snow
showers. N-NW winds will begin increasing but there remains
uncertainty how fast things dry tonight before refreeze takes
place. Combination of snowmelt and rainfall could rapidly
refreeze in Northern Maine making for slick travel on untreated
surfaces. Across the areas seeing rainfall refreeze is a higher
concern because rain will taper, cannot rule out brief
snowflakes, then temperatures crash. Flash freeze is possible
for untreated surfaces from the Central Highlands to Downeast
coast including Bangor. Temperatures bottom out in the teens
north with 20s south and cold breezy NW winds develop into
Friday.

KEY MESSAGE 2...Well below normal temperatures Saturday,
followed by moderating temperatures Sunday, then a light wintry
mix on Monday.

KEY MESSAGE 2 DESCRIPTION...
High temperatures Saturday will be a good 10 to 15 degrees
below normal for this time of year. Fortunately, winds are not
expected to be all that strong, so wind chills are not expected
to be too extreme during the day. Temperatures will moderate
closer to normal levels by Sunday, but it will still be a few
degrees below normal for this time of year. A fast moving
weather system will approach the region Monday bringing a
snow/rain mix to northern areas Monday and the chance of rain
downeast. Temperatures are expected to rise to above normal
levels Monday afternoon ahead of an approaching cold front.
