...Clipper system to produce light to moderate snow across Great Lakes and
interior Northeast through Sunday...
...Atmospheric River to generate moderate-to-heavy rainfall in the Pacific
Northwest through Sunday...
...Elevated fire weather across Southern California and part of the
Southern Plains through Sunday...
Winter Weather Advisories and Winter Storm Warnings remain in effect
across parts of northern New England on the backside of a departing potent
winter storm responsible for producing several inches of snow and gusty
winds across much of the interior Northeast on Friday. Blowing snow caused
by windy conditions are likely to remain a hazard for the interior
Northeast today. An Alberta clipper system will drop into the Midwest
today, bringing with it the chance for wintry weather across the Great
Lakes. This system will blanket portions of the Great Lakes and interior
Northeast in 1-3 inches of snow with isolated higher amounts, particularly
downwind of lake Eerie where they may get between 4-8 inches by Sunday
morning. A cutoff-low over northern Mexico will be the trigger for
showers and thunderstorms across the Texas and the Texas/Louisiana Gulf
coasts today. Thunderstorms are not expected to be severe. The cutoff-low
is then expected to phase with the northern stream allowing for the
extension of the surface cold front from the Midwest down through the
Mississippi Valley.
An atmospheric river event is forecast to produce several inches of rain
across the Pacific Northwest through Sunday. Most of the heavy
precipitation associated with this system is likely to occur today though,
with tomorrows rainfall being more confined to the Olympic and northern
Cascade mountain ranges. A ridging pattern across the West and Central
U.S. will generate anomalous warmth across portions of the Northern and
Central Plains on Sunday and Monday. High temperatures are likely to be in
the low 60s across northeastern Montana on Sunday which would constitute a
25-30 degree departure from normal for them for this time of year. The
warm air will expand into the Northern/Central Plains on Monday where
highs may reach between 15-20 degrees above average. Dry and breezy
conditions will contribute to an elevated fire weather risk across
southern California today and Sunday. Locally critical fire risk may also
develop, according to the Storm Prediction Center, due to an exacerbation
of the aforementioned surface conditions. Winds will pick up on the
backside of a surface front passing through the Southern Plains today.
Paired with already dry conditions, this region may experience an elevated
fire weather threat today.

Extended Forecast Discussion
NWS Weather Prediction Center College Park MD
159 AM EST Sat Nov 27 2021
Valid 12Z Tue Nov 30 2021 - 12Z Sat Dec 04 2021
...Overview...
Persistent moist inflow into the Pacific Northwest should cause
additional precipitation there, with the heaviest likely Tuesday
into Wednesday.
Multiple shortwaves will pivot through the mean trough that will
be in place over the central and eastern portions of the CONUS
during the extended periods; which will help deamplify the pattern
somewhat as next week progresses. Rounds of light precipitation
are possible for the Great Lakes region and interior Northeast
through the week. Persistent moist inflow into the Pacific
Northwest should cause additional precipitation there, with the
heaviest likely on Wednesday.
...Guidance/Predictability Assessment...
The 12Z/18Z guidance has a fairly decent handle on the large scale
pattern evolution with the troughiness over the East and ridging
over the West. However, uncertainties remain with energy coming
into the trough in the East that will affect positioning and depth
of a surface low off the Northeast coast. Ensemble guidance
continues to show spread with the central pressure as well as its
position. The 18Z run of the GFS has trended somewhat slower and
less amplified than the 12Z run with the shortwaves traversing
central and eastern Canada/United States. By Thursday evening, it
reverses and the pattern becomes more progressive across the
Northeast U.S. There is fairly good agreement for potent shortwave
energy to move across the Great Lakes through Wednesday; however
with potentially more shortwave energy passes through the flow
over the Great Lakes region by Thursday, the spread in possible
tracks increase as it tracks northeastward. The WPC once again
attempted to take a middle ground solution of the GFS and ECMWF
deterministic and ensemble mean positions for the low.
For the West, at least initially, model guidance is clustered
fairly well with the ridging but this changes beyond Wednesday.
These differences may impact the forecast not only in regards to
how much moisture is drawn onshore but also the amounts of
precipitation reaching western Washington from British Columbia as
well as precipitation type (the ridgier GFS suite has less
precipitation farther south and staying all rain, with the EC/CMC
wetter and lower snow levels). The model spread increases further
by the mid-to-late periods which decreases the predictability and
forecast confidence. The EC mean and the GEFS means end up showing
a mean trough across the central U.S. on Friday, which the 00Z
deterministic ECMWF and CMC were closer to compared to the 00Z and
06Z GFS runs that kept low amplitude troughing over the Northwest
and Northeast instead. Uncertainty is rather high by that point
given the small magnitude of the impactful shortwaves and the
energy arising from high latitudes and over the Pacific.
The WPC forecast was based on a combination of the deterministic
00Z ECMWF, OOZ CMC,00Z and 06Z GFS initially. As the period
progressed, weighted the GEFS and ECWMF means more to minimize
individual model differences, as well as lessening GFS influence
as GFS runs were not aligned with the means by later in the week.
...Weather/Hazards Highlights...
Portions of the northern Cascades and the Olympic Peninsula will
begin to have precipitation ramping back up becoming moderate to
heavy through Wednesday for the western portions of Washington.
Some of this will likely fall as snow near the highest terrain but
there is uncertainty in snow levels. Portions of the Northern
Rockies are also expected to have light precipitation with this
flow. Periodic shortwave energy across the north-central to
northeastern U.S. will cause rounds of light precipitation chances
through those areas. Favored lake enhancement areas will see the
best chance for snowfall becoming moderate, especially downwind of
Lake Ontario, as northwesterly flow passes across the open lakes.
Additionally, the low offshore of the Northeast could cause light
wraparound rain or snowfall through Monday, with amounts depending
on the low track. Other than these two highlighted regions, a
majority of the country will be generally dry other than
increasing moisture for Texas midweek onward and spreading into
the Mid-South by Thursday/Friday.
Temperatures are expected to mostly be slightly below normal
across the Eastern U.S. Monday as the mean trough becomes
reinforced, with moderation back towards normal Wednesday and
Thursday. Much of the western and central states will maintain
mild temperatures through the extended forecast thanks to the
ridging over the region. A few locations may reach or exceed daily
maximum and minimum temperature records, where some places could
register 20 to 30 degrees above seasonal average. As the flow
flattens during the late period, above normal temperatures should
also begin expanding into the Midwest and South.

Typical and breezy trade wind pattern with some occasional and
light windward/mountain focus for showers is expected with high
pressure in place north and east of the state this weekend. A
trough is expected advance to the north by Sunday, then shift
southeast Monday before it retrogrades to the west midweek. This
change will disrupt the trade winds however the associated surface
cold front should stay to the north of Hawaii, so sensible weather
impacts should be limited. The breezy trade winds should return by
the middle of next week as high pressure again builds in to the
north and a cutoff low settles to the east of Hawaii. As this low
drifts it my draw in increased moisture with the possibility of
increased shower activity for the Big Island and Maui. There is
spread with the guidance on how much moisture and the location of
this low feature.

...THERE IS A SLIGHT RISK OF EXCESSIVE RAINFALL OVER PORTIONS OF
THE COASTAL RANGES OF WASHINGTON AND FAR NORTHERN WASHINGTON
CASCADES...
A moderate to strong Atmospheric River event looks to impact
portions of the Pacific Northwest (i.e. the Olympic and Cascade
Mountain ranges) beginning this morning, although there is a
consistent signal that the more intense rainfall rates will arrive
later in the day (primarily after 21z). By that time, deep
westerly on-shore flow of 35-55 kts will help to flatten large
scale ridging with a highly anomalous plume of deep tropospheric
moisture (with PWATs as high as 1.4 inches) advancing inland. By
28/00Z, GEFS precipitable water values exceed the 95th percentile
of climatology (+3 SD) focused along the Olympic Peninsula
southward along the coastal ranges into Oregon. Model guidance is
in good agreement concerning two distinct QPF maxima of 3-5 inches
centered where upslope flow is maximized (near the Olympic
Peninsula and along the northern Cascades respectively). The two
Slight Risk areas have once again been maintained for this update,
encompassing the aforementioned QPF maxima. Marginal Risk areas
surround those above regions, extending primarily southward into
extreme northwest portions of Oregon where 1-3 inches of
precipitation will be more common.

...Northeast...
Days 1-3...
The ongoing storm system will begin to pull away from the region
with the best forcing and potential for accumulating snow winding
down after 18Z today. The greatest probabilities for widespread
accumulating snow will be confined to northern/down east Maine
this morning as well as portions of the higher peaks of northern
VT/NH where WPC probabilities for 2" remain as high as 40 percent.
Attention then turns to another potential storm system during the
late day 2 into day 3 time frame /late Sunday into Monday/. A fast
moving shortwave trough swinging through the large scale cyclonic
flow present is forecast to close off at 500 mb over Ontario. The
increasingly negative tilted trough will spawn a surface low off
the Northeast/New England coast that is then forecast to lift
quickly east/northeast. There is considerable model spread in the
timing and location of the potential offshore surface low and its
track. The 00Z deterministic models continue to show some
variability, with the CMC/GFS/ECMWF being more offshore, keeping
the bulk of any accumulating snow well offshore. However, the NAM
advertises a much closer storm track to the coast and would wrap
around accumulating snow along coastal New England.
The WSE plumes and viewer highlights well the forecast uncertainty
with its large spread of potential solutions. Despite the lower
confidence, the WPC probabilities for 4" this cycle did trend
higher and now are in the 20-30 percent range (with some isolated
maximum of 40 percent). This system bears a close watch given the
current uncertainty and potential for heavy snow along coastal New
England.
...Pacific Northwest...
Days 2-3...
Modest shortwaves embedded within fast mid-level flow will move
onshore British Columbia, Canada Sunday, and Washington State on
Monday. Each of these shortwaves will produce enhanced ascent in a
column characterized by PWs of around +2 standard deviations above
the climo mean. Each shortwave will be accompanied by a frontal
system and WAA, which will produce additional ascent and provide
enhanced moisture, but also raise snow levels as high as 9000 ft
during the period of heaviest precipitation. This will keep heavy
snow well above pass levels, and WPC probabilities for 4 inches
are high only on D2 into the first part of D3 in the northern
Cascades of WA.
...Great Lakes...
Days 1-3...
Within the larger cyclonic flow across the Great Lakes, several
fast-moving embedded shortwave troughs will swing through over the
next 48-72 hours. The first tracks through the Upper Midwest and
lower Great Lakes later today through Sunday and overall is the
expected weaker system of the three. Quick on its heels is a much
stronger shortwave trough that is forecast to pass a bit further
north Sunday, eventually closing off a low at 500mb over Ontario.
Finally, on Monday /D3/, another shortwave trough will race
through the Great Lakes, bringing renewed chances of snowfall to
the region.
The first system is expected to produce a narrow swath of
generally light snowfall across northern/northeast WI, both
peninsulas of Michigan, and downwind of Lake Erie, where the
combination of synoptic forcing and lake enhanced flow could lead
to slightly higher totals. Day 1 WPC probabilities for 2 inches
are moderate (50-60 percent) with the greatest signal (still
slight) of 4 inches being immediately downwind of the lakes,
particularly Lake Erie in the favored snow belt region of western
NY and northwest PA. The second, stronger system will favor more
lake effect snow, particularly downwind Lake Erie and Ontario
where WPC probabilities for 4" reach moderate to locally high
levels, especially across the NY Southern Tier region.
Finally, the third shortwave passing through for Monday /D3/ still
has some uncertainty in its eventual track and also strength. A
multi-model consensus approach yields a storm track across the
northern Great Lakes which would favor lake effect snows off
Superior, northern Michigan and Lake Erie. Still time to iron out
more details and specifics but potential exists for another round
of 2-4 inches with highest totals confined to downwind of the
lakes in the favored snow belt regions. The highest WPC
probabilities for 4" are downwind Lake Erie at this point.
For Days 1-3, the probability of significant icing is less than 10
percent.

159 AM EST Sat Nov 27 2021
Valid 12Z Tue Nov 30 2021 - 12Z Sat Dec 04 2021
...Overview...
Persistent moist inflow into the Pacific Northwest should cause
additional precipitation there, with the heaviest likely Tuesday
into Wednesday.
Multiple shortwaves will pivot through the mean trough that will
be in place over the central and eastern portions of the CONUS
during the extended periods; which will help deamplify the pattern
somewhat as next week progresses. Rounds of light precipitation
are possible for the Great Lakes region and interior Northeast
through the week. Persistent moist inflow into the Pacific
Northwest should cause additional precipitation there, with the
heaviest likely on Wednesday.
...Guidance/Predictability Assessment...
The 12Z/18Z guidance has a fairly decent handle on the large scale
pattern evolution with the troughiness over the East and ridging
over the West. However, uncertainties remain with energy coming
into the trough in the East that will affect positioning and depth
of a surface low off the Northeast coast. Ensemble guidance
continues to show spread with the central pressure as well as its
position. The 18Z run of the GFS has trended somewhat slower and
less amplified than the 12Z run with the shortwaves traversing
central and eastern Canada/United States. By Thursday evening, it
reverses and the pattern becomes more progressive across the
Northeast U.S. There is fairly good agreement for potent shortwave
energy to move across the Great Lakes through Wednesday; however
with potentially more shortwave energy passes through the flow
over the Great Lakes region by Thursday, the spread in possible
tracks increase as it tracks northeastward. The WPC once again
attempted to take a middle ground solution of the GFS and ECMWF
deterministic and ensemble mean positions for the low.
For the West, at least initially, model guidance is clustered
fairly well with the ridging but this changes beyond Wednesday.
These differences may impact the forecast not only in regards to
how much moisture is drawn onshore but also the amounts of
precipitation reaching western Washington from British Columbia as
well as precipitation type (the ridgier GFS suite has less
precipitation farther south and staying all rain, with the EC/CMC
wetter and lower snow levels). The model spread increases further
by the mid-to-late periods which decreases the predictability and
forecast confidence. The EC mean and the GEFS means end up showing
a mean trough across the central U.S. on Friday, which the 00Z
deterministic ECMWF and CMC were closer to compared to the 00Z and
06Z GFS runs that kept low amplitude troughing over the Northwest
and Northeast instead. Uncertainty is rather high by that point
given the small magnitude of the impactful shortwaves and the
energy arising from high latitudes and over the Pacific.
The WPC forecast was based on a combination of the deterministic
00Z ECMWF, OOZ CMC,00Z and 06Z GFS initially. As the period
progressed, weighted the GEFS and ECWMF means more to minimize
individual model differences, as well as lessening GFS influence
as GFS runs were not aligned with the means by later in the week.
...Weather/Hazards Highlights...
Portions of the northern Cascades and the Olympic Peninsula will
begin to have precipitation ramping back up becoming moderate to
heavy through Wednesday for the western portions of Washington.
Some of this will likely fall as snow near the highest terrain but
there is uncertainty in snow levels. Portions of the Northern
Rockies are also expected to have light precipitation with this
flow. Periodic shortwave energy across the north-central to
northeastern U.S. will cause rounds of light precipitation chances
through those areas. Favored lake enhancement areas will see the
best chance for snowfall becoming moderate, especially downwind of
Lake Ontario, as northwesterly flow passes across the open lakes.
Additionally, the low offshore of the Northeast could cause light
wraparound rain or snowfall through Monday, with amounts depending
on the low track. Other than these two highlighted regions, a
majority of the country will be generally dry other than
increasing moisture for Texas midweek onward and spreading into
the Mid-South by Thursday/Friday.
Temperatures are expected to mostly be slightly below normal
across the Eastern U.S. Monday as the mean trough becomes
reinforced, with moderation back towards normal Wednesday and
Thursday. Much of the western and central states will maintain
mild temperatures through the extended forecast thanks to the
ridging over the region. A few locations may reach or exceed daily
maximum and minimum temperature records, where some places could
register 20 to 30 degrees above seasonal average. As the flow
flattens during the late period, above normal temperatures should
also begin expanding into the Midwest and South.
