Synopsis A generally fair and mainly stable weather pattern
is expected to prevail across the local isles much of this week.

Short term Tonight thru Tuesday...

a building mid to upper level ridge will continue to dominate the
local weather regime through the forecast cycle. This feature is
expected to erode the available moisture resulting in precipitable
water values below one inch by Monday. At lower levels, a surface
high pressure across the east central atlantic will yield easterly
winds through Monday, becoming more east northeast on Tuesday as
another surface high pressure builds north of the area. The local
pressure gradient is in fact expected to tighten as the surface
high builds north of the area and across the western atlantic.

Having said that, continue to expect fair and stable weather
conditions with limited shower activity each day.

Long term Wed thru Mon issued 437 am ast Sun feb 17 2019
fair weather is expected to prevail in the long term forecast. Dry
airmass is expected to persist and only a few brief patches of
moisture are expected to move through, which may bring some brief
shower to the local area. The mid and upper levels will maintain a
stable atmosphere as well. Latest forecast soundings still
indicate a strong inversion and very dry mid levels, which is
consistent with the mid and upper level ridges and low
precipitable water values. East to east northeast winds of 15 to
20 mph are expected across the local waters and coastal areas. So
given the stable atmosphere, dry air, and breezy conditions,
mainly fair weather conditions are to be expected with moments of
brief showers during the night and morning hours. That said, the
marine conditions are expected to deteriorate starting midweek,
more on that in the marine section below.

Marine Seas below small craft advisory criteria through midweek.

As a result, continue to expect seas 3 to 5 feet across the offshore
waters, ranging between 2 and 4 feet nearshore. Marine conditions
are expected to deteriorate by Wednesday with a northerly swell
and fresh east northeast winds.

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.
