Synopsis
A weak cold front will drop south across northern new england
today and stall over southern new england tonight. Low pressure
moving through the great lakes will spread some light snow
across the region late Monday into Monday night, with the
stalled front lifting northward as a warm front. Low pressure
tracks east along this front on Tuesday with snow changing to
sleet and freezing rain before temperatures warm. As the low
moves east it will pull a cold front through the region Tuesday
night with colder weather arriving for the next few days.

Near term until 6 pm this evening
1100 am update...

high and mid level clouds will prevail across the region this
afternoon as a weak cold front remains stalled over southern new
england. Temperatures will top out in the mid 30s to mid 40s.

Have adjusted temp TD sky and rh grids to reflect current obs
and Sat pics. No other changes planned attm.

Prev disc...

update...

have updated the grids based on current conditions. Temperatures
have begun the morning very mild with readings above freezing in
most locations, even northern areas. Have adjusted afternoon
highs upwards based on this trend. Much of the cloud cover in
central maine has dissipated with plenty of low clouds situated
over new hampshire. Have adjusted the forecast accordingly for
this morning based on most recent satellite imagery. Otherwise,
no significant changes to the forecast.

Prev disc...

clouds will continue to streak across the forecast
area in the proximity of a weak, stalled out front. High clouds
will persist in the south with low cloudiness over central and
northern areas. Early morning fog in the keene area is expected
to dissipate after sunrise.

Expect 30s in northern areas today, with lower to mid 40s in the
south allowing for more melting. The gradient will relax towards
the afternoon hours.

Short term 6 pm this evening through 6 pm Monday
Clouds will increase and thicken tonight as a warm air
advection pattern develops after midnight and the front begins
to move north.

This warm front will likely stall near the massachusetts and
new hampshire state lines tonight and Monday. This will allow a
nose of colder, drier air to filter into the region as high
pressure remains entrenched over southeast canada.

Wet bulbing effect will likely allow the precipitation type to
begin as all snow even over southern areas. However, significant
warming aloft will occur by late Monday allowing for some rain
and snow mix over far southern new hampshire as the
precipitation will remain light. This mix will occur as boundary
layer temperatures warm into the 30s late in the day as a broad
area of low pressure heads towards the great lakes. A wave of
low pressure will likely form along the maine coast however as
we head into the long term portion of the forecast.

Long term Monday night through Saturday
Surface warm front tries to lift northward Monday night, but
cold air damming at the surface will likely hold tough and force
this warm front aloft. Light snow ahead of the warm front moves
across the area with generally 1 to 3 inches expected.

Temperatures aloft warm above freezing after the warm front
passes, though any precipitation behind the warm front will
likely be in the form of light drizzle or freezing drizzle. Next
round of precipitation arrives on Tuesday as the complex low
pressure system arrives from the west. Steadier precipitation
picks up again, this time with a highly inverted low level
temperature profile supporting widespread freezing rain to the
north of the surface warm coastal front. Models still are having
a tough time resolving this low level cold wedge of air, though
the cmc and NAM have done the best job showing the cold surface
temperatures hanging on through midday Tuesday in interior
western maine. Have based the temperature and wind forecast off
of a blend of these two models with some manual adjustments.

Although we do expect much of the area to see some freezing
rain, the impact will likely be less than normal considering the
coating of snow expected beforehand. South of the warm coastal
front temperatures will warm into the 40s to low 50s ending the
freezing rain threat. Cannot rule out a rumble of thunder
considering moist adiabatic mid level temperature profile.

Cold occluded front pushes through the area Tuesday afternoon
and evening, ending the steadier precipitation. With winds
shifting to the west behind the front, any remaining cold air
damming will break allowing the dammed areas to warm up a bit
before colder temperatures arrive by Wednesday morning. Some
lingering snow showers are possible through the day Wednesday as
the upper low moves by. Colder temperatures expected Thursday
and Friday, though not all that cold by mid winter standards or
even this winter standards. Surface high pressure shifts across
the area Friday night allowing a southerly flow to bring a warm
up for next weekend.

Aviation 16z Sunday through Thursday
Short term...VFR conditions today with areas of MVFR ceilings
in the mountains. Areas of MVFR ceilings develop later tonight
into Monday as onshore flow sets up.

Long term... Expect ifr conditions with light snow moving across
the area Monday night. Snow changes to sleet and freezing rain
on Tuesday across interior portions, while southern, western,
and coastal sections will warm above freezing earlier in the day
Tuesday. Expect low level wind sheer in the cold air dammed
areas of interior western maine and eastern new hampshire. Cold
front moves through Tuesday evening bringing the steadier
precipitation to an end and a gradual improvement toVFR by
Wednesday. Lower ceilings may linger in the mountains right
through the day Wednesday into Wednesday night before
dispersing.

Marine
Short term... Gradient continues to relax. Have dropped scas for
the early morning hours. A few gusts near 25 kt are possible
well off the midcoast region early, but these will be
diminishing as well.

Long term... Warm front lifts north across the gulf of maine
Monday into Monday night. Low pressure moving east along the
front will allow southerly winds to increase to gale force ahead
of it. There is a low probability that some storm force gusts
could occur. The low will drag a cold front across the gulf of
maine late Tuesday, with winds behind the front possibly
reaching gale force again on Wednesday.

Hydrology
Many rivers remain frozen and or affected by ice jams. With
additional liquid precipitation expected over much of the area
on Tuesday, it is possible that there could be more ice movement
and some minor flooding into Wednesday.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... None.

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

For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
