Marine Weather and Tides
Damariscotta, 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.

Synopsis
A cold front will drop south across the region tonight into
Thursday. This front may bring widely scattered showers, mainly
in the north. Otherwise, high pressure builds in Thursday night
and Friday with fair weather. Low pressure approaches from the
west early on Saturday with the potential for showers and
perhaps thunder Saturday afternoon through Sunday night. High
pressure then builds in later Monday into Tuesday.

Near term through tonight
We'll be sandwiched in between two systems tonight. The first, a
cold front dropping in from the north may bring a few showers to
northern zones tonight while low pressure moving south of new
england remains far enough south to keep southern zones dry. The
net result for much of the forecast area will be an increase in
clouds. Lows will be in the 40s well north with 50s pretty much
everywhere else.

Short term Thursday through Thursday night
A lingering inverted trof across southern and central zones may
bring a couple of light showers or sprinkles for the first part
of Thursday but the vast majority of the forecast area will be
dry. High pressure then builds in Thursday night with dry air
and diminishing winds. This will result in good radiational
cooling conditions later Thursday night allowing for
temperatures to drop well down into the 40s at the better
radiators, and possibly upper 30s across the far north.

Long term Friday through Wednesday
The deterministic model solutions are in decent agreement on the
long wave pattern through late next week. An upper trough lifts
out as we begin the forecast period with a flattening ridge for
Friday and the start of the upcoming weekend bringing dry weather
and warmer temperatures. By late Saturday... A shortwave impulse
from the midwest will approach the region. At the surface... Low
pressure over the lower great lakes will track down the saint
lawrence valley pushing a warm front northward into the area with
clouds and an increasing chance of showers and scattered
thunderstorms. The trailing cold front will cross the forecast
area on Sunday accompanied by a second round of convection.

Meanwhile... Shortwave energy along the u.S. Canadian border will
carve out another trough across the great lakes and northeast
conus that will slide quickly eastward. This trough will drive a
second cold front across the area with a few showers and
thunderstorms Sunday night and Monday. In the wake of this
trough... Rising heights under building high pressure surface and
aloft with warm dry weather for Tuesday and Wednesday. By late
Thursday into Friday... The next shortwave impulse and an associated
frontal system will approach from the great lakes.

Aviation 18z Wednesday through Monday
Short term...VFR conditions are expected tonight through
Thursday. Winds will shift to the north later tonight or early
Thursday morning as a cold front passes through the region, then
from the east Thursday afternoon.

Long term...

sat night - sun... Areas of MVFR in shra -tsra with LCL ifr in fog.

Mon... Sct MVFR in -shra -tsra.

Marine
Short term... Winds and seas will remain below SCA thresholds
tonight through Thursday night.

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.
