Area Forecast Discussion
National Weather Service Boston/Norton MA
343 PM EST Thu Nov 28 2019
.SYNOPSIS...
Dry, blustery and cold conditions will continue into Friday
night with diminishing wind Saturday as high pressure builds
into the region. A storm system will likely bring wintry
weather to Southern New England late Sunday into Tuesday.
Cooler and drier conditions then prevail for the midweek
period.
&&
.NEAR TERM /THROUGH TONIGHT/...
Mid level low well east of ACK will continue to move east
tonight. Last of the showers are rotating south across the
Cape/Islands but scattered ocean effect showers will linger
until evening. Steep low level lapse rates over the water with
ocean induced Capes around 200 J/kg and delta T from SST to top
of the boundary layer around 17C with northerly trajectory
supports a few ocean effect showers.
Any showers will end by this evening, otherwise clearing skies
as low level drying moves into SNE. Continued risk of 40-50
mph gusts over the Cape and Nantucket this evening and will
continue the wind advisory here until midnight. Dropped the
advisory for the eastern MA coast as wind gusts have not reached
advisory criteria. Still gusty winds across SNE into this
evening before gradually diminishing overnight, but remaining
gusty along the coast. Lows will drop into the 20s, except lower
30s near the coast.
&&
.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
Strong pressure gradient will persist across SNE right into Fri
night as high pres remains south of James Bay with strong low
pres east of Nova Scotia. Result will be continued gusty winds
Friday although not as strong as today. Winds will diminish
somewhat Fri night in the interior as the surface decouples
from the boundary layer, but gusty winds will persist near the
coast and over elevated terrain. Very dry air through the
column so lots of sunshine Fri and clear skies Fri night. Temps
below normal with highs upper 30s to low/mid 40s Fri, and lows
upper teens to mid 20s Fri night.
&&
.LONG TERM /SATURDAY THROUGH THURSDAY/...
Highlights...
* Dry with cold low temperatures Saturday into Saturday night.
* Storm system could bring impactful amounts of snow Sunday into
Monday especially interior Southern New England. Timing and
amounts still highly uncertain.
* Cooler temperatures for Tuesday into mid to late next week.
Details...
Amplified, slow-evolving 500 mb pattern per GFS/ECMWF ensemble mean,
featuring initial troughing in the Northeast, a ridge from the Upper
Midwest to the Mississippi Valley, and a large trough over the West
Coast. This pattern becomes more progressive and breaks down through
the period, as the large Western US trough progresses through the
Rockies and northern Plains into the northern Appalachians thru
Sunday, and begins to slow as it moves ENE over the waters near or
south of Southern New England Monday into Monday night. This upper-
level system and its related sfc cyclone will be the main source of
potentially impactful sensible wx in the period Sunday night and
into Monday - details of which will hinge on eventual surface low
track, its forward speed and the extent to which above-freezing low-
level air/warm nose may intrude.
A broad trough is carved out across eastern North America in the
wake of this system into the mid- to late-week period. Thus, a
tendency for cooler-than-normal temperatures should prevail for the
period.
Saturday:
Surface ridge of high pressure is maintained on Saturday, leading to
cool and dry weather. Continued NW winds 10-15 mph with occasional
gusts to 25 mph early on Saturday, though wind speeds and gusts to
subside thru Saturday afternoon and into the night. Highs should
only top out in the 30s, coldest NW MA into northern Worcester
County and upper 30s toward northern CT into the South Coast, Cape
and Islands. Clear and dry conditions for much of the overnight with
lows in the mid teens to mid 20s. And importantly, 2-m wet bulb
temperatures off the GFS, NAM and SREF mean are progged in the low
teens to low 20s by Sunday morning.
Sunday into Monday Night:
* Increasing confidence on a winter storm affecting at least
interior southern New England late Sunday into Monday, though
details to depend on storm track, when storm exits and how much
warm air aloft can change precipitation type.
In looking at model guidance, the ECMWF and its ensemble mean along
with the Canadian GEM have lied on a more southern/colder solution
track, with the 00z/06z GFS being further to the north and advancing
a warm-nose into towns at least as far north as the Mass Pike. There
remains considerable spread in the ensemble membership low tracks in
both ensembles. However the 12z ECMWF and GFS operational runs each
have trended southward and slower; the shorter wavelength between
the trough now exiting our area with this one may also favor a more
southern track. Will have to see if this southern track trend
continues to hold.
While there remains a lot of unresolved details due to uncertainty
in the guidance, there's increased confidence on at least some
wintry weather especially for interior southern New England (mainly
N/W of the I-95 corridor) on Sunday night into Monday night.
1) Timing
Air mass preceding the warm-frontal precip bands is apt to be quite
dry, with plenty of wet-bulb cooling potential even through the
lower atmosphere. Though temps may be slowly warming from cold lows
from Saturday night, precip that does begin should start as snow for
most of Southern New England by mid-morning to noon across northern
CT into western MA and by Sunday afternoon across the rest of
central/eastern MA into RI.
What is less clear is on precipitation type changeovers and also
when precipitation comes to an end. The first consideration will
depend on the extent of warm nose intrusion inland; at the moment,
the better potential for mixed p-type changeover is south of the
Mass Pike, and especially towards the South Coast, coastal RI into
Cape Cod and the Islands Sunday night into Monday. Precipitation
should eventually transition back to snow Monday, but a cyclone
becoming more vertically stacked may keep precip going even into a
part of Tuesday especially eastern into coastal MA and into RI.
2) Amounts
With uncertainty in when precipitation ends, and on the extent of
mixed p-types cutting into accumulations, there is still
considerable uncertainty in any accumulation forecast at this
juncture. The 12z ECMWF ensemble QPF paints total QPF from about
0.75" to an inch from NW Mass/northern CT into the I-95 corridor, to
up to 1.25 inches towards the coastal plain into Cape Cod and the
Islands. I do think the ECMWF ensemble probabilities of snow
accumulations at or over 6 inches best captures the area that has
the potential for accumulations of snow, with rather high probs
shown from the Hartford-Providence-Boston corridor north and west,
with lower probs towards coastal RI into South Shore and the Cape
and Islands.
3) Waves/Coastal Flooding
We are also monitoring the potential for coastal flooding.
Fortunately, astronomical tides are low which cuts into the
potential. With wave heights in the 10-15 foot range in eastern/NE
MA waters, given tidal forecasts it would take a 1.5-2 ft storm
surge (as northeast winds increase) to produce even minor flooding
at sites such as Scituate, Plymouth and towards the North Shore
during Monday's high tide.
Tuesday onward:
Low pressure will then pull away into the Canadian Maritimes on
Tuesday, with weak sfc ridging for Tuesday night into Wednesday.
Depending on if there's any snowpack on the ground, could have some
lows that are pretty chilly for Tuesday night.
Temperatures will start to trend cooler than normal, though
significant/well-below normal temperatures don't look as likely at
this point. A clipper type system for Wednesday night into Thursday
offers the next chance for precip, though amounts limited.
