Synopsis
Low pressure will track to our west and drag an occluded front
across the area early Saturday. Ahead of this front we'll see
rain become heavy at times later today and tonight. The rain
will taper to showers by Saturday morning. This latest round of
rain will likely cause some flooding issues late tonight and
Saturday. Another system will pass south of the region late
Sunday and yet another one for early next week as our active
weather pattern continues.

Near term through today
At 06z... A 1018 millibar ridge from the bay of fundy southward
across the gulf of maine. A 998 millibar low over northern ohio
with a warm front extending eastward through the mid atlantic
region and a trailing cold front through the mississippi valley.

Goes imagery shows mid and high clouds steadily expanding north
and east across the forecast area as the surface ridge retreats
further offshore. NWS doppler radar mosaic shows a blossoming
area of rain and embedded thunder upstream from the lower great
lakes region through the mid atlantic region. For today... Northern
and southern stream energy evident in GOES water vapor imagery
undergoes phasing with upper trough quickly going negative
tilt. At the surface... Low pressure will track slowly northeast
to the lower ottawa valley by evening with the trailing
cold occluded front extending through eastern new york state.

Ahead of this feature... 50 knot low level jet will transport
high precipitable water values northward into the forecast area.

Rain will develop across the area by later this morning then
become heavy at times later today. It'll be a damp and chilly
day with clouds... Precipitation and an onshore flow limiting
highs to the upper 40s and lower 50s.

Short term tonight through 6 pm Saturday
For tonight the surface low meanders over southern quebec with
the trailing cold occluded front moving east and along and
parallel to the maine-new hampshire by dawn. Ahead of the front
the low level jet will produce a round of heavy rain tonight
along with the potential for embedded thunder. It'll be a windy
night across the higher terrain and along the coast where
several hours of southeast winds gusting close to 40 mph will be
possible. Low temperatures will range from the upper 30s to mid
40s across the area. On Saturday... Rain quickly tapers to
showers from west to east behind the departing frontal system.

The cold cyclonic flow and proximity of the upper trough will
result in a cloudy day along with a few lingering showers. Highs
will range from the upper 40s to lower 50s... With a gusty
southwest wind making it feel even cooler.

Long term Saturday night through Thursday
00z operational guidance and model ensembles remain in
relatively good agreement with the daily features in the
extended portion of the forecast.

There will be a few remaining scattered showers Saturday night
as the surface system shifts into the canadian maritimes and the
upper level support gradually exits the region. Some of the rain
showers may be mixed with snow showers in the mountains with
locally light accumulations possible.

A very weak system will pass south of our forecast area on
Sunday embedded within the fast flow aloft. Behind this system,
cooler air will arrive in maine and new hampshire Sunday night
as a northwesterly gradient increases over the region with cold
air advection. H8 temperatures in the -2c range in the south to
the -8c range in the north will yield temperatures only in the
40s and 50s across the region for highs on Monday despite
sunshine associated with high pressure.

Yet another weak and fast moving system will race south of our
region on Tuesday. This will bring a period of light rain to
northern new england.

A surface ridge will briefly build into new england from the
hudson bay region on Wednesday before a system approaches from
the west on Thursday keeping an active pattern in place.

Aviation 06z Friday through Tuesday
Short term through Saturday ... Conditions lowering to MVFR
this morning and then ifr by afternoon in rain and fog. Heavy
rain likely tonight with ifr lifr conditions and llws likely.

Southeast winds along the coast may gust up to 35 kt. Conditions
gradually improve toVFR throughout Saturday with lingering
MVFR in CIGS and sct -shra in mountain sections.

Long term... Localized MVFR conditions in any leftover scattered
rain or snow showers Saturday night. Areas of MVFR conditions
are possible Sunday night as a system passes by south of our
region. Another weak system will pass south of our region on
Tuesday, leading to lowered ceilings and visibilities, mainly in
the south.

Marine
Short term through Saturday ... Southeast flow steadily
increases Friday ahead of an approaching storm system with sca's
by late in the day. A period of southeast gales is possible
tonight ahead of a cold occluded frontal passage. Sca's are
likely Saturday following the frontal passage.

Long term... Winds may gust into SCA thresholds Sunday night
during a period of cold air advection within an increased
northwesterly gradient. A southeasterly gradient will increase
on Thursday of next week.

Hydrology
A widespread 1-1.5 inches of rain is expected today and tonight.

However, south and southeastern facing slopes of the white
mountains and portions of the western me mountains will see an
upslope enhancement to the rainfall with some 3 inch amounts
possible. Since rivers are already running high we expect
renewed rises, especially late tonight and Saturday. Therefore,
a flood watch remains posted for the most flood-prone zones at
this time. The watch has been expanded to include coastal york
county to include areas near the mouth of the saco river. With
snowmelt being a minimal contributor at this point in the year,
we think mainly minor flooding will be the theme.

Gyx watches warnings advisories
Me... Flood watch from this afternoon through late Saturday night
for mez007>009-012>014-018>021-023-024.

Nh... Flood watch from this afternoon through late Saturday night
for nhz001>006.

Marine... Gale watch from late tonight through Saturday morning for
anz150>154.

Small craft advisory from 2 pm this afternoon to midnight edt
tonight for anz150>154.
