snow attm as snow/sleet lifting across the southern Maine coast.
Current forecast looks good w/adjustments to the hrly temps to
match up w/the latest obs.
Previous Discussion...
Not much chg to our prev fcst with the upcoming wntr stm.
Changes this update include upgrading coastal Hancock county to
a wntr stm wrng for mainly combined snfl and sleet with some
fzra with mixed precip msly likely ovrngt into Tue morn, with
more in the way of snfl in the aftn.
Otherwise, models have been consistent with the track of the
low and the xtnt of deformation snfl banding working from Wrn
interior Downeast areas mid to late morn into far Northern areas
by aftn. Meso models in particular are in indicating the max
potential of 2 to 3 inches of sn/hr as this band traverses nwrd
keeping it's intensity into NE ptns of the FA, but weakening as
it moves toward NW ME. Subsequently, there will be a cut-off
gradient of snfl ovr the NW where entr wx advs were issued.
Still though, snfl potential ovr the max snfl corridor has been
raised a couple of inches from the prev fcst, with max 8 to 12
inch band fcst psnd at the 75 percentile toward the max
potential of multi model ensbls. Snfl totals will rapidly
transition from arnd an inch across the immediate Downeast coast
and outer islands which may even get a a brief pd of all rn Tue
morn to sig higher sn, sleet, and ice totals further inland
across Downeast areas. Lastly, where steady all snfl is
occurring where winds gusts to at or more than 25 mph, patchy
blowing sn is xpctd.
Sn and or mixed precip will gradually taper to sct sn shwrs from
SW to NE across the FA late Tue aftn thru mid eve, with scattered
snow shwrs ending across Downeast and Cntrl areas ovrngt, but
holding on across the N with little in the way of additional
snfl.

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
A low pressure system over Nova Scotia moving east towards the maritimes
will bring some more snow to Eastern Maine. A ridge of higher
pressure will briefly build into Maine Tuesday night, ahead of a
trough that will move in Wednesday afternoon bringing some more
light snow to portions of the forecast area. The trough will
move into New Brunswick late Thursday afternoon.
Loaded a blend of the GFS/NAM/ECMWF/GEM for DP/wind/skycon. Used
Diurnal tool for temp. Consall for QPF.

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
A trough of low pressure will move east into New Brunswick
early in the period. A few lingering snowshowers across Northern
Maine Thursday night into the early hours Friday morning.
Higher pressure will build into the area Friday morning and will
ridge through by Saturday evening. A frontal system will dip
down from Canada into western Maine Sunday morning bringing
another round of snow to the area. A low over Wisconsin will
attach to the front Sunday afternoon and stall the forward
progression of the front. The front will stall across Maine as
the low moves slowly east across the Great Lakes. The low will
move into Quebec Tuesday morning, then on to NE Quebec Tuesday
evening finally moving the front to the east of Maine. By the
end of the period. The upper low will be centered over central
Quebec, with higher pressure building into Southern Quebec.
Loaded a blend of models to smooth out the minor differences.
