The Winter Weather Advisory for portions of Cape Cod has been
cancelled. The band of snow showers has moved south of the Cape
this evening, leaving mainly clear skies. We are expecting the
band of snow showers to lift northward again well after midnight,
but it may only lift as far as the extreme south coast of Cape
Cod. This may cause additional accumulation into early Christmas
morning from Falmouth to Hyannis, however amounts, if any, are 
expected to be light.

Area Forecast Discussion
National Weather Service Boston/Norton MA
717 AM EST Sat Dec 24 2022

.SYNOPSIS...
Cold and dry holiday weekend for most of southern New England,
but scattered ocean-effect snow showers will impact the Cape and
Islands today. High pressure will bring dry weather next week
with a gradual warming trend, then rain showers are possible for
New Year's weekend as low pressure approaches from the Ohio
Valley.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
715 AM Update:

Issued a Winter Weather Advisory for Block Island and Martha's
Vineyard. Getting reports of 1-2" so far and seeing visibility
down to 1/2SM on both islands. Earlier thinking below...

* Ocean Effect Snow is the focus for today

Made some adjustments to PoPs for the band of ocean effect snow
affecting the Islands, leaning heavily on 06z 3km NAM which has
a great handle on its current position and expected trends.
This is an unusual situation that we often only see with SW flow
when there is a departing arctic airmass. It's actually rather
shallow, only up to around 3,000 ft in depth, which is why it
looks unimpressive on radar, but IR satellite shows its origins
are in Long Island Sound and it extends across Block Island to
Martha's Vineyard and Chatham.

Looking at NAM soundings, there's roughly 500 J/kg of ocean-
induced CAPE and little if any directional shear in the mixing
layer. Two things stand out that should limit accumulations -
one is the fact that wind speeds are rather strong in the mixing
layer which minimizes parcel residence time over the water and
the other is the fact most of the lift is occurring in the
colder air outside of the maximum dendritic growth zone.
Additionally, the band is expected to migrate south of Block
Island and the Vineyard this morning, before heading back north
toward Cape Cod this afternoon, so it shouldn't stay over one
area too long. We did bump up snowfall totals to 1-3" and it
wouldn't be surprising to see one or two 4" amounts in more
persistent bands, but confidence isn't high enough to issue
Advisories just yet. So far it looks like an inch at most from
looking at webcams.

Otherwise forecast is on track.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/...
Pressure gradient continues to diminish tonight into Sunday.
Low temperatures tonight expected to be similar to those this
morning. High temperatures Sunday should be higher than today as
the airmass continues to moderate over our region. This,
combined with more of a west wind, should bring the ocean-effect
snow showers to an end, although some clouds are likely to
linger across the islands into Christmas Day.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Highlights:
 * Dry next week with a gradual warming trend.
 * Mild with rain showers possible over New Year's weekend.

Significant pattern change will get underway next week as closed
low that's bringing our current Arctic blast exits Quebec and is
replaced by rising heights across much of eastern U.S. as
subtropical ridge builds off eastern seaboard. Models do show
one short wave rotating around trough Tuesday, which could bring
a few rain or snow showers, but airmass looks fairly dry so it
may end up just producing some cloudiness.

Looking farther ahead, ensembles show high probability of
temperatures reaching 50 degrees or higher over New Year's
weekend. At same time, there is an indication that low pressure
will be making its way east from Ohio Valley, bringing an
increased chance of rain showers as well.

&&

.AVIATION /12Z SATURDAY THROUGH WEDNESDAY/...
Forecaster Confidence Levels:

Low - less than 30 percent.
Medium - 30 to 60 percent.
High - greater than 60 percent.

.MARINE...
Forecaster Confidence Levels:

Low - less than 30 percent.

Warnings, which will gradually be converted to Small Craft
Advisories with time. Some of the nearshore waters will likely
be converted later this morning, but most waters will see gale-
force gusts into this evening.

...A BAND OF OCEAN EFFECT SNOW WILL AFFECT THE ISLANDS THIS
MORNING...

At 5 AM EST, a band of ocean effect snow extended from Long Island
Sound to Block Island and Martha's Vineyard.

The band of snow will wobble back and forth this morning, and will
continue to affect Block Island and Martha's Vineyard. It may also
graze Cape Cod from Falmouth to Chatham, as well as Nantucket.

Most locations will pick up an inch or two of snow, but one or two
places could see as much as 3 or 4 inches where these snow showers
are more persistent.

Be prepared for changes in visibility and road conditions.
