Marine Weather and Tides
Belfast, ME

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Low pressure approaches from the southwest today with the
potential for showers which will continue into Monday. High
pressure then builds in later Monday, bringing dry conditions
into midweek next week along with a moderating trend in

Near term until 6 pm this evening
Noon update... Increasing showers across southern new

9am update... Widely scattered showers should increase in
coverage through the day today. Temperatures have warmed a bit
faster this morning but with the overcast skies don't expect
much change in high temperatures.

Prev disc...

a complex weather system will approach northern new
england today. An area of warm air advection situated with a
warm front over the mid atlantic region will approach the
southern new england coastline today. Best dynamics will be
shunted south of our forecast area, however a few showers may
reach southern maine and southeastern new hampshire from this

Thereafter, an upper level disturbance will approach the region
from the northern ohio valley. This will bring more showers to
the region, mainly this afternoon. With a cloud cover and a
chilly onshore flow, expect temperatures to remain in the 60s
today. This will keep the lower levels of the atmosphere
relatively stable. However, slantwise elevated convection is a
possibility above the surface. Will therefore keep the chance
for thunder in the forecast in concurrence with SPC this

Short term 6 pm this evening through 6 pm Sunday
The upper level feature will cross the region tonight with more
scattered showers. Lower levels of the atmosphere will be fully
saturated by this point, so expect areas of fog across the

On Sunday, do not expect any improvement with more shower
activity, albeit temperatures will be slightly milder. This
precipitation will be triggered by another impulse dropping into
the upper level trough. A weak area of low pressure at the
surface will cross southern portions of the forecast area during
the day. It will be more muggy for the later half of the weekend
and slightly milder.

Expect a quarter to a half inch of precipitation for rainfall
totals on Saturday and Sunday. This is well needed precipitation
with potentially more expected in the long range portion of the
forecast for the beginning of the work week.

Long term Sunday night through Friday
Low pressure will move east through the gulf of maine Sunday
night producing a steady rain overnight. Expect most areas to
see beneficial accumulations of a half to one inch by Monday
morning. Lows will range through the 50s to near 60.

Lingering morning showers in eastern zones will gradually shift
east on Monday and skies will brighten from west to east through
early afternoon... Although low and mid level moisture will linger
into the evening hours. Highs Monday afternoon will range from
the mid 60s north to the mid 70s south.

High pressure building in from the west will bring clearing
skies Monday night with lows from the mid 40s to lower 50s.

High pressure will crest over the region early Tuesday before
shifting offshore south of new england. Looking for mostly sunny
skies with seasonable temps. Highs will range through the 70s to
near 80 degrees.

Shortwave approaching from the west Tuesday night will bring
increasing high clouds after midnight as a warm front approaches
from the west. Lows overnight will range through the 50s.

Warm front will lift into the region on Wednesday bringing
clouds and scattered showers. Best chance for rain will be in
northern zones in the vicinity of best over-running. Highs will
range from the mid 70s north to the mid 80s south.

Low pressure crossing southern canada will drive a cold front
toward the region Wednesday night and this boundary will shift
into western zones by Thursday morning. Looking for showers
overnight with some scattered thunderstorms. Lows will range
from the upper 50s to mid 60s.

Cold front will continue to slowly push eastward on Thursday and
will continue to be the focus for showers and
thunderstorms... Esecially in eastern zones where heating will
generate some moderate CAPE by early afternoon. Moderate shear
in the mid levels may produce some isolated severe cells in the
afternoon in eastern zones. Highs will range from the mid 70s to
mid 80s.

Aviation 18z Saturday through Thursday
Short term... Ceilings and visibilities lowering to MVFR in
scattered showers today with perhaps a thunderstorm. Areas of
fog tonight and early Sunday with ifr conditions gradually
improving to MVFR during the day.

Long term... MVFR conditions in scattered showers and
thunderstorms Monday with an upper level trough and again on
Thursday with the passage of a cold front.

Short term... Conditions below SCA thresholds. Fog developing by
tonight for the waters, lowering visibilities.

Long term... Sca's may be needed Wednesday night.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
