Marine Weather and Tides
Kennebunk, 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
Warm front lifts northwards across the region overnight bringing
scattered showers. Thunderstorms may develop across southern new
hampshire Sunday with more widespread rain Sunday night as low
pressure crosses the area. High pressure builds east out of the
great lakes on Tuesday and Wednesday. A broad trough swings
cross the northeast on Thursday with showers possible. Then much
warmer air builds in for the rest of the week.

Near term tonight
Scattered showers will continue across the region through the
evening. Low pressure is currently located over lake ontario and
will move northeastwards across london and kitchner ontario
overnight. Ahead of this low a broad warm front and area of lift
extends all the way to the new hampshire seacoast. Scattered
showers will move north across the area and decrease in coverage
overnight.

With very moist low levels remaining overnight in the wake of
the showers expect areas of both drizzle and fog to form through
morning with low temperatures and dew points remaining in the
50s.

Short term Sunday and Sunday night
Sunday morning will see the warm front draped across the
northern portion of new hampshire and western maine. In the
northern portion of the area expect the cloud cover to hold on
throughout the day, making temperatures lower and thunderstorms
less likely although scattered showers are still a concern.

Across southern new hampshire thunderstorms are more likely and
severe thunderstorms can't be ruled out. On the warm side of the
front, temperatures will climb to near 80s with a chance for
sun to break out. If Sun is able to reach the surface the
resulting instability will likely result in scattered
thunderstorms. Forecast soundings show descent CAPE of up to
1200 j kg with around 50kts of 0-6km shear which could be enough
to support a few damaging wind gusts. This threat is still a
low probability scenario depending on how much of the cloud
cover can dissipate in the morning but will be something to keep
an eye on through Sunday morning.

Sunday night will see more widespread rain develop as the low
center tracks from hamilton ontario across new york and
massachusetts.

Long term Monday through Saturday
Big picture continues to show a large upper level ridge over the
northwest canada and a downstream trough to the east of that,
keeping round after round of modified arctic high pressure en
route through new england. However, there are signs this pattern
is beginning to change. Cut off low over the rocky mountains
will move east across the continent midweek, arriving in our
area on Thursday as it becomes embedded in the westerlies. As
this trough lifts out, the subtropical ridges will push the
storm track to our north and allow warm, humid air to build into
our area this weekend, bringing summer heat just in time for
july.

Sharp upper trough drops in behind the departing surface low on
Monday with cool temperatures expected and a chance of showers,
drying up as the day GOES on. Monday night into Tuesday morning
will see high pressure moving through the area leading to good
radiational cooling conditions. Based on expected dewpoints, low
temperatures will be mostly in the 40s, with low 40s or even
upper 30s possible in northern valleys. Dewpoints are higher
than they were with last week's cold, so do not expect a frost
with this one.

Expect gradually warming conditions Tuesday and Wednesday as
high pressure shifts east. Tuesday will be mostly clear, but by
Wednesday the upper trough approaching from the west will bring
in additional cloud cover. Southerly flow will allow the coast
of maine to remain cooler.

Upper trough (the remnant rocky mountain cut off low) will track
across new england Wednesday night into Thursday. Will see a
chance of showers as it does so, but with the surface low
passing to our north any rain will be scattered in nature and
not the widespread drenching that our gardens might want.

High pressure builds out of the southeastern us and into new
england on Friday, with bermuda high pressure to the east
building west as well. The result will be the arrival of a hot
and humid air mass that will likely persist through the weekend.

With our new lower heat advisory criteria, would expect that
heat advisories will be needed during this period, possibly
lasting into early next week.

Aviation 19z Saturday through Thursday
Short term... Ceilings have generally held on asVFR despite
widespread cloud cover today with just the nh seacoast dropping
to MVFR. Showers will continue on and off through the afternoon
with temporary reductions to visibility into the ifr range
during the heaviest showers. Overnight expect the low level
moisture to remain trapped in the area with widespread ifr
conditions in fog and drizzle. Sunday will see conditions
improve to MVFR at daybreak and then toVFR while maintaining
overcast through the day. Again a few showers are expected
areawide with thunderstorms across southern new hampshire.

Long term... Low pressure moves out on Monday, so we should see
conditions improving toVFR area wide, becoming clear Monday
night with patchy valley fog.VFR continues Tuesday and
Wednesday, but increasing clouds are expected Wednesday and
Wednesday night with conditions lowering to ifr by Thursday.

Marine
Short term... Quiet conditions over the waters as relatively
weak flow continues.

Long term... As the low moves away on Monday, expect a brief
northerly flow over the gulf of maine. High pressure crests to
the south on Tuesday with southwest flow increasing Wednesday.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... None.

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.
