.SYNOPSIS...
An upper level low slowly lifts up to our north today. High
pressure slowly builds across to our north through the weekend
into early next week.
&&
.NEAR TERM /THROUGH SATURDAY/...
Upper level trough remains across the eastern portion of the
nation today. Expect partly sunny skies today with afternoon
highs in the low to mid 50s across the north and mid to upper
50s for the Bangor region and Downeast. A weak upper disturbance
moving through the region will result in mainly cloudy skies
tonight. A few showers are possible, mainly for the Bangor
region and Downeast, where a surface trough will be located
providing some weak lift. Moisture is limited, so any rain that
does fall will be a few hundreths at best. Saturday will be
partly sunny to mostly cloudy and dry, as some weak ridging
aloft builds in across. Afternoon highs on Saturday will range
from the upper 40s to lower 50s across the north and mid 50s for
the Bangor region and Downeast.
&&
.SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/...
Vertically stacked low and associated trough move northeast
through the weekend, causing unsettled weather and periods of
light rain showers. Upper-level shortwave from the west tracks
east Saturday night, bringing a chance of light rain to northern
Maine. Plenty of low-level moisture, so anticipating mostly
cloudy skies and a potential for river valley fog to develop.
West/northwesterly winds that are relatively light. Sunday into
Sunday night, surface ridging builds-in from the west, as
upper-level cutoff low settles over New England. Temperatures do
go cold enough overnight that there could be a few snowflakes
that fall late this weekend in the early morning period, but not
enough for any accumulation. Daytime highs in the mid-to-upper
40s in the north, and 50s along the coast. Overnight lows
Saturday night and Sunday night in the 30s across northern and
eastern Maine.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
Cutoff low sticks in Maine, before interacting with a
vertically stacked low system in the mid-west. From here, low
system interacts with another low along the waters, sliding up
along the Maine coast, bringing another round of rain for
northern and eastern Maine later next week as a Rex Block
pattern with high pressure to the north develops. Cannot rule of
some snow flakes in the early mornings. High temperatures
generally in the 40s and 50s along the coast, and lows generally
in the 30s.
