Synopsis
Low pressure will track across southern new england before
exiting the coast this evening. This disturbance will produce
rain and a light wintry mix across portions of the interior
through late today. A cold front will push through the region
Tuesday night resulting in upslope showers and a brisk northwesterly
flow Wednesday into thurday. A weak ridge will build into the
region on Thursday and remain through Friday. The next storm
will approach the region on Friday night bringing widespread
precipitation for late Friday into Saturday. The best chance of
showers will be across northern and mountain sections with
approach of the cold front.

Near term /through tonight/
Steadier precipitation is tapering from southwest to northeast
with passage of the shortwave impulse evident on GOES water
vapor imagery. At the surface... Low pressure was centered over
southeast massachusetts and will slide offshore during the next
few hours. The steadier mixed precipitation will linger across
the mountains... Vicinity of the international border... Next few
hours and will hold on to the current winter weather advisory
headline there. Otherwise... Steadier rain and mixed precipitation
over central maine will exit that area over the next hour and
the advisory will be expired there. Overnight... Mostly cloudy
with abundant low level moisture with some patchy drizzle and
fog. Low will be mainly in the lower and mid 30s with some upper
20s across the northern mountains.

Short term /Tuesday through Tuesday night/
Onshore flow tomorrow and tomorrow night ahead of a northern
stream impulse and associated cold front. Highs mainly in the
40s in the onshore flow with a few 50 degree readings over
southern new hampshire and connecticut valley.

Long term /Wednesday through Sunday/
A short wave trough will move across the region on Wednesday as
low pressure departs to our southeast. Colder air will filter
into the region Wednesday and especially Wednesday night on
increasing northerly winds. Upslope snow showers should be
prevalent in the mountains both Wed and Wed night.

The next possible precipitation maker is agreed upon by most
deterministic models and ensembles to arrive Friday or Friday
night. However, significant differences in short wave/sfc low
track exist which allows for spread in thermal profiles and qpf
coverage. At this time, it does appear that some accumulating
snow and and/or mixed precipitation will be possible later
Friday and Friday night, and perhaps into Saturday. However,
there is a chance that the bulk of the precipitation shield
gets suppressed to our south, leaving us dry or with just a
little light precip.

Aviation /19z Monday through Saturday/
Short term... Ifr will likely persist through tonight in clouds
and areas of drizzle and fog... With some improvement to MVFR on
tue.

Long term...

small craft conditions are likely Wednesday night Thursday as
northwesterly flow moves over the waters in the wake of the cold
frontal passage. Small crafts are once again possible over the
weekend depending on track and strength of low pressure.

Marine
Short term... Should see marginal small craft in all but casco
bay into tonight. Small craft seas should linger into Tuesday
outside the bays.

Long term...

small craft conditions are likely Thursday as northwesterly
flow moves over the waters in the wake of the cold frontal
passage.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
