Synopsis
A cold front will cross the region tonight and will be followed
by high pressure on Friday. High pressure will hold over the
region on Saturday and will drift east Saturday night and
Sunday. A cold front will slowly approach from the west Sunday
night and Monday and will stall to the west of the region Monday
night and Tuesday. The front will slowly drift east Tuesday
night and Wednesday.

Near term through tonight
Weak moisture starved cold front will swing through the region
overnight with little more than passing clouds through the
evening hours. Lows overnight will generally range through the
40s.

Short term Friday through Friday night
High pressure will gradually build in from the west on Friday.

Will see a slightly cooler day but temperatures will remain
above normal. Should see a mix of clouds and Sun in the north
and mostly sunny skies south. Highs will range from the mid 50s
to lower 60s north and mid 60s to near 70 south.

High pressure will continue to build in from the west Friday
night. Expect partly cloudy skies overnight with lows from the
mid 30s north to the mid 40s south.

Long term Saturday through Thursday
This weekend an anomalous ridge will build along the east coast
nwd thru hudson bay. Ensemble progs suggest the middle of the
ridge will be around 3 standard deviations above normal for this
time of year. What that means for sensible wx is continued much
above normal temps and dry. Model guidance continues to push low
teens h8 temps and mid teens h9 temps around the periphery of
the surface high and into new england. Mixing should stay fairly
shallow and remain around h9... But those temps still translate
to widespread 70s and pushing 75+ in the warm spots. The multi-
model consensus blend seems a little cool... Especially into
early next week... So I have increased temps a few degrees by
mixing down h9 temps and blending in some MOS guidance.

With deep... Meridional flow developing early next week across
the central conus... Flow parallel to the front will tend to keep
things slow moving. 19.12z model guidance did slow the arrival
of precip compared to yesterday. So I have decreased pop a
little from the multi-model consensus tue... With likely pop
reserved for Tue night wed. Late in the period deterministic and
ensemble guidance is also trending towards a blocky pattern in
the north atlantic. This may keep the baroclinic zone just
offshore and allow a focus for when the upper low ejects out of
the southeast. Consensus has trended towards a two part rainfall
event... With the lead wave arriving midweek... And the upper low
arriving late in the week.

Aviation 18z Thursday through Tuesday
Short term...VFR tonight through Friday night.

Long term... WidespreadVFR conditions will continue under high
pressure. High will be more centered overhead over the
weekend... So valley fog and lifr conditions will be possible at
hie and leb. Return flow develops Mon into tue... And that may
keep things mixed enough to prevent fog in the valleys.

Increasing moisture may lead to coastal stratus however.

Marine
Short term... Continuing sca's for the bays and outer waters.

Long term... As trof digs into the central CONUS early next
week... Developing sly flow may build seas above 5 ft outside the
bays. As sly LLJ increases midweek... SCA are likely with seas
approaching 10 ft. In general wind gusts should remain below 25
kts on the coastal waters until midweek.

Fire weather
Relative humidities will drop into the upper 20s to mid 30s in
southeast new hampshire and southwest maine tomorrow afternoon
along with winds of 10 to 20 mph. This will result in an elevated
fire danger in these areas for several hours during the
afternoon. Will likely highlight this in a special weather
statement issued on the midnight shift.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... Small craft advisory until 6 am edt Friday for anz151-153.

Small craft advisory until 6 pm edt Friday for anz150-152-154.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
