pressure approaches from the south on Friday, crossing the
region through the weekend.

.NEAR TERM /THROUGH WEDNESDAY/...
11:30 PM Update...Snow is mostly concentrated in the western
highlands with only some bands of lighter snow elsewhere. One
band of snow was circulating down from the north and may effect
parts of far northern Maine. In addition, some convective
elements have been forming across the north so will hang on to
the winter weather advisory even though amounts across the far
north will be limited. Increased pops in the western highlands
this hour. Otherwise, no major changes were made.

Previous Discussion:
Low pressure continues to develop across the region with snow
currently falling across much of Central Maine, a mix of snow
and rain along the Interior Downeast, and rain along the coast.
Current observations and the latest high resolution guidance
continue to support the potential for moderate to heavy snowfall
across the Central and Western Highlands where a trough is
developing between the low to our west and a low to our far
east. Expect some of the highest totals of 3 to 6 inches to be
found in this area, with the greatest amounts in the higher
terrain. Farther north, the upper level dynamics will be weaker
resulting in lower snow amounts, particularly in northeast
Aroostook county where downsloping off the higher terrain north
and east of the St. John River in New Brunswick will result in
weaker lift. Expect not much more than an inch or two in the
Caribou and Presque Isle area.

Precipitation ends early Wednesday morning as the low exits to
the east. Expect a blustery NW flow during the day along with
clearing skies. Enough moisture and lift may be in place to
support a few snow showers in the north during the afternoon.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
H5 trof will be crossing the area on Wednesday night with isolated
snow showers acrs the far north in the evening. Skies will be clear
acrs most of the area overnight with temps dipping into the 20s as
system departs into the North Atlantic.

Sfc ridge axis crosses the CWA on Thursday with sunny skies in the
morning giving way to partly sunny skies as warm front begins to
nose twd New England.

Upr low fcst to dig into the OH and TV valleys Thursday night and
eventually begin to close off on Friday. H5 ridge likely to be
located over the CWA but high-mid deck encroaching on the area in sw
flow will lead to mostly cloudy skies. Latest guidance is not giving
any indication that pcpn will be in any hurry to move in the area
toward the end of the week.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
Sfc high pressure will be sitting over ern Canada Friday night but
guidance continues to differ on where the closed low will track.
Given the synoptic pattern will likely be a cloudy and fairly wet
weekend with temps still above average. Upr ridge builds in on
Monday with temps warming back into the 50s through the end of the
period.
