.SYNOPSIS...
High pressure builds into the region through Saturday, then slowly
slides to the east into Monday. A cold front approaches from the
west Monday night, then slowly crosses the area from Tuesday into
Wednesday.
&&
.NEAR TERM /THROUGH SATURDAY NIGHT/...
The cold front will progress through the region tonight. Models
are in good agreement with the cold front exiting over the
waters by early tonight. The majority of the showers should exit
the state by then, but cannot rule an isolated shower in
Downeast areas. With the cooler airmass behind the system, temps
will drop into the 50s across the area.
For Saturday, high pressure settles back into the region. Sunny
skies and with NW flow will push temps into the mid to upper 70s
in the north and low 80s in the south. For Saturday night, high
pressure remains in the region, with clear skies and temps in
the mid to upper 50s.
&&
.SHORT TERM /SUNDAY THROUGH MONDAY/...
Weak northern stream shortwaves pass to the north and south of
the region from Sunday into Sunday night. With the best dynamics
associated with the southern shortwave passing well to the
south, have opted to limit the pops to slight chance across the
North Sunday and Sunday night. There appears there will be
sufficient instability late Sunday afternoon/Sunday evening to
warrant a slight chance of thunder as well (combo of Showalter
indices falling to around 0 and 500-1200 J/kg of CAPE). Shear
though should be relatively modest with only 20-30kt of 0-6km
bulk shear, coupled with Bulk Richardson NUmbers generally 50
and above, expect storms likley to not be severe and possibly
not even strong. Should see a storm mode of pulse and possibly
some multi-cellular storms. Highs on Sunday should be near to
around 5 degrees above normal and lows Sunday night around 5
degrees above normal.
Most models show northern stream ridging building in for Monday,
however a small minority of ensemble members suggest that some
showers could develop out ahead of the next system over far western
zones late in the day. Have slight chance pops in for that. Highs on
Monday should be around 5 degrees above normal.
&&
.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
A northern stream shortwave approaches Monday night, then crosses
the region on Tuesday. This should bring some showers and possibly a
rumble of thunder as well from late Monday night through Tuesday.
The best chance for any showers/thunderstorms should be across the
North.
A mean northern stream longwave trough builds in Tuesday night-
Thursday. The models differ in their timing of the individual
shortwaves rotating around the base of the trough as it builds in.
As a result, limit pops to at most chance Tuesday night/Wednesday
and at most slight chance Wednesday night and Thursday. Could see a
few thunderstorms as well Tuesday night across the entire region,
and across Downeast Maine and the Bangor/Penobscot Region Wednesday
afternoon.
&&
.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
NEAR TERM: VFR conditions for all terminals tonight through
Saturday night. NNW winds around 5 kts tonight and Saturday.
Winds shift Saturday night to S and light.
SHORT TERM:
Sunday-Monday...Most likely VFR, with a low end chance for MVFR
if any convection occurs. SW-WSW winds G15-20KT possible
Sunday.
Monday night...VFR, except for a low end chance for MVFR in any
convection late at western terminals.
Tuesday-Wednesday...MVFR or lower possible with any stronger
convection, otherwise VFR.
&&
.MARINE...
NEAR TERM: Winds and seas will remain below SCA conditions
tonight through Saturday night.
SHORT TERM: A relaxed pressure gradient over the waters should limit
winds to 10 kt or less and seas to 2 ft or less Sunday-Wednesday.
Thunderstorms are possible over the waters from Tuesday into
Wednesday.
&&
.CAR WATCHES/WARNINGS/ADVISORIES...

030.
