Marine Weather and Tides
Williams, MA

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.

631 am edt Fri jun 22 2018

High pressure will be near new england today. Clouds will
increase ahead of a warm front tonight with showers moving in
for Saturday. A low pressure system approaching from the eastern
great lakes region will continue the threat of showers with
isolated thunderstorms Saturday night, as a cold front will keep
the threat of showers and thunderstorms going to close the

Near term until 6 pm this evening
As of 622 am edt... High pressure will be over northern new
england this morning, and then drift offshore during the
afternoon. It will be a delightful partly to mostly sunny day
with comfortable humidity levels. After a cool start with temps
in the 40s and 50s (a few 30s over the adirondack park), temps
will rebound to seasonal normals. Some high clouds continue to
be over the south southwest extreme of the forecast area based
on the observations and 10.35 micron clean IR goes-16 loop this

Some mid and high clouds will continue to increase south and
west of the capital region, as a closed h500 low embedded in a
mid and upper level trough moves over the midwest. These clouds
will advance ahead of warm front over the oh valley and mid
atlantic states, as well as a secondary coastal wave near the
carolinas. These high clouds could keep temps down a couple of
degrees over the eastern catskills, mid hudson valley and NW ct,
but we tended to lean towards the warmer ECMWF mos and GFS mos
values with highs in the upper 70s to lower 80s in the valleys
and upper 60s to mid 70s over the higher terrain.

Short term 6 pm this evening through Sunday
Tonight... The mid and upper level riding weakens over the
northeast with the mid and upper level flow becoming
southwesterly ahead of the upper trough. Clouds continue to
increase, thicken and lower from the south and west. Some weak
isentropic lift well in advance the warm front will start to
saturate the column with spotty showers or light rain impacting
locations south and west of the capital region. Lows will be
milder than this morning with mainly 50s with a few upper 40s
in the southern adirondacks.

Saturday... A cool, gray, and wet start of the weekend is likely
to occur with an mid and upper level trough moving over the
great lakes region and midwest. In the southwest flow, moisture
convergence increases ahead of the sfc wave. Periods of showers
will start to overspread the entire forecast area by the lunch
time hour. The guidance is variable with the the ECMWF cmc
having the strong isentropic lift and dynamics enhancing the
rainfall over the southern half of the forecast area, whereas
the NAM is over the northern tier. We tended to enhance the
rainfall to categorical values over the east facing slopes of
the catskills and adirondacks with the E SE boundary layer
flows. A few thunderstorms could pop up in the mid to late pm
with the showalter stability indices dipping below zero. We
trended the MAX temps down more towards a blend of the
gfs nam ECMWF guidance with highs only in the mid to upper 60s
over the valley areas, and upper 50s to lower 60s over the mtns.

Saturday night... Weak elevated instability will still be around
in the evening, and decent moisture convergence occurs ahead of
the warm front and the weak sfc wave with the upper low that
turns neutral to negatively tilted. We tapered the showers to
chance or slight chance after midnight, as a pseudo warm sector
sets up over the forecast area. Min temps will not drop off too
much with lows not far off from Saturdays highs with mid 50s to
lower 60s.

Sunday... A more humid air mass will be over the region with sfc
dewpts in the upper 50s to mid 60s. Another short-wave and a
cold front will move south southeast towards the region. Cloud
cover may be a problem limiting instability north and west of
albany, but there are some trends for breaks in the clouds from
the capital region south and east. Better instability may
materialize with the GFS now showing sbcapes of 1000-1500 j kg
across the southern zones with increasing shear. Some strong
thunderstorms may occur if this magnitude of instability is
realized. We placed a chance of thunderstorms across the
forecast area, especially in the afternoon with likely showers.

Highs will be closer to seasonal norms compared to
Saturday... With mid 70s to lower 80s from the capital region,
upper hudson valley, and bennington, vt south and east, and mid
60s to lowers 70s north and west.

Long term Sunday night through Thursday
For Sunday night... Expect showers to linger as a secondary cold
front crosses the forecast area. While additional precipitation
amounts will not be that great, an additional tenth of an inch
or so of rain may fall. Lows Sunday night will be in the upper 40s
to mid 60s.

Dry weather is expected Monday through Tuesday night as high
pressure builds southeast from the upper great lakes Monday morning
settling across our region on Tuesday and moving just off the
eastern seaboard by Wednesday. Highs on Monday will range from the
upper 60s to upper 70s, with lows Monday night in the upper 40s to
mid 50s. Highs on Tuesday will be in the 70s to around 80 with
lows Tuesday night generally in the 50s.

For Wednesday clouds will be increasing along with an increasing
chance of showers as low pressure tracks eastward from the upper
great lakes accompanied by a vigorous upper level trough. Clouds and
the threat of showers and thunderstorms will linger Wednesday
night into Thursday until the upper level trough passes east of the
area. Highs on Wednesday from the upper 70s to mid 80s. Lows
Wednesday night will be in the upper 50s to mid 60s with highs on
Thursday in the mid 70s to mid 80s.

Aviation 12z Friday through Tuesday
Vfr conditions expected through the TAF period 12z Saturday
as high pressure moves across new england and then out to sea.

Clouds will increase today as low pressure approaches from the
ohio valley, and mid- level ceilings are forecast at kpou and
kpsf this by mid afternoon. A rain shower is possible at kpou
after 06z Saturday, but low chance so only vcsh in kpou TAF for

Light and variable winds this morning will become southeast at
6-10 kts by this afternoon and continue tonight.


Saturday night: moderate operational impact. Likely shra... Slight
chc tsra.

Sunday: high operational impact. Likely shra... Chc tsra.

Sunday night: moderate operational impact. Chance of shra.

Monday: low operational impact. Slight chance of shra.

Monday night to Tuesday: no operational impact. No sig wx.

Fire weather
High pressure will be near new york and new england
today, and then drift offshore tonight. A low pressure system
and a warm front will bring showers and isolated thunderstorms
to the region Saturday into Saturday night. A cold front will
focus some scattered showers and thunderstorms on Sunday.

The rh values will lower to 30 to 45 percent this afternoon, and
then increase to 80 to 100 percent tonight. In the wetting
rainfall on Saturday the rh values will remain elevated at 65 to
85 percent.

The winds will be light today from the southeast to south at
less than 10 mph. East to southeast winds will persist Friday
night into Saturday at 5 to 15 mph.

A widespread soaking rainfall Saturday through Sunday will
likely occur with the periods of showers and isolated to
scattered thunderstorms.

No hydro problems are expected over the next week. Most of the
entire hydro service area hsa is under abnormally dry
conditions according to the latest us drought monitor.

A dry air mass will be over the hsa until Saturday morning.

There is a high likelihood of widespread rainfall Saturday into
Sunday night with basin average rainfall amounts of a half an
inch to an inch, though locally higher amounts are possible with
any thunderstorms.

Minimal rises are expected on the waterways. Dry weather
returns Monday afternoon into the midweek.

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.
