Synopsis
Developing low pressure off the mid atlantic coast will intensify
as it moves rapidly northeast through the gulf of maine on Wednesday.

High pressure builds eastward into the region late in the week
and into the weekend with a return southwest flow bringing
warmer temperatures by the weekend.

Near term until 6 am Wednesday morning
1125 pm... Minor estf update to reflect the current mesonet and
radar trends in near term grids.

Prev disc...

836 pm update...

minor changes to the forecast as the snowfall event begins. Have
adjusted pops to better match latest cam forecasts as well as
current radar trends. Inverted coastal low pressure is
developing off the DELMARVA peninsula and will make its way
north overnight spreading snow to the remainder of new england
tomorrow.

528 pm update...

light precipitation has begun for portions of nh and me... With
ceilings beginning to drop. A few stations are reporting light
snow and this trend will continue with snow spreading from west
to east tonight and increasing in heaviness with time. Forecast
is on track at this time. Will be refreshing products shortly.

Previous discussion...

all headlines remain in place from the noon time update.

Model data incomplete here today but the general consensus is
for the progressive upper trof over the great lakes to continue
to move east and allow development of a weak surface low off
delmarva tonight. With the southwest flow ahead of the upper
trof, the low will track northeast. Tonight ahead of this low, a
waa pattern develops spreading snow from south to north rather
quickly. Toward morning additional moisture influx off the ocean
combined with increasing UVV will allow the snow to increase in
intensity. Accumulating snow over southern and coastal areas
can be expected toward morning. Temps will be cold so all snow
expected no issues with ptype.

Short term 6 am Wednesday morning through Wednesday night
Models tracking sfc low parallel and closer to the me nh coast
than prior runs. They have become in line with prior runs of
the euro which had shown great continuity for this system and
also the higher in forecast QPF amounts. With the track being
closer to the coast, we have nudged QPF and snowfall totals
higher over southern and coastal areas with the highest amounts
being along the midcoast areas. QPF amounts should be in the
range of .50-.75 inches over coastal areas which should generate
snowfall amounts of 5-10 inches midcoast maine with 5-8 inches
over southern and south central nh and interior adjacent areas
to the maine coast. Amounts further north and in the mountains
will be significantly less. With winds from the north and some
cold air damming to occur find it hard for temps to reach above
freezing along the coast so lowered temps a few degrees.

By later in the day the center of low pressure will move rapidly
northeast and be off the coast of downeast maine so lingering
snows will continue but the heaviest will be over.

Clearing will occur Wednesday night as the upper trof and
surface low quickly exit to the east. Temps in the wake of the
system will be seasonable with overnight lows generally in the
teens to lower 20s.

Long term Thursday through Tuesday
Little in the way of significant weather is in the cards thu
through the weekend. Temperatures are however expected to warm
once again - into the 40s in many areas over the weekend. The
next system of interest continues to be a potentially decent
precip maker - with warm air flooding in from the south (at
least aloft anyway) Monday-Tuesday timeframe. Therefore will
continue to monitor trends for potential mixed precip and or
rain which could cause additional ice jam problems. Ice could
end up being an issue as well-especially up north.

Aviation 04z Wednesday through Sunday
Short term... Conditions will deteriorate to MVFR then ifr from
southwest to northeast tonight as snow spreads across the
region. Conditions will be ifr to ocnl lifr from 09z-18z. By
late Wed conditions improve and becomeVFR Wed night.

Long term... Occasional MVFR conditions in snow showers in the
mountains Thu and Fri otherwise widespreadVFR expected through
the weekend.

Marine
Short term... Offshore swells continue to slowly subside. Winds
are light. Will continue a SCA due to hazardous seas for the
southwest offshore portion of the waters into early this
evening. Winds will remain below SCA conditions tonight into
wed night, but offshore swells will increase Wed through wed
night so have issued a SCA for hazardous seas over the outer
waters for that time frame.

Long term... SCA to low-end gale conditions will be possible
Saturday.

Hydrology
All rivers but the kennebec at aug have fallen below flood
stage, but ice jams have frozen into place in some areas. Rivers
will still need to be monitored as these jams could move
without notice.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. 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.
