.synopsis...
low pressure progressing into the eastern great lakes tonight
will drag a strong cold front through the region this evening.
this low will slowly lift into the canadian maritimes thursday
as high pressure builds into the ohio valley. a fast moving
clipper system will drop from the upper midwest through the ohio
valley thursday night and friday followed by another clipper
and arctic cold front saturday. a trough will then remain across
the great lakes through sunday.

&&

.near term /through thursday night/...
we are now in the second phase of the synoptic portion of this
weather system. afternoon satellite and water vapor loops show
the impressive mid/upper shortwave trough dropping from lower
michigan east/southeast through the southern great lakes. the
left exit of a 125-135 knot h3 jet streak rounding the base of
this trough per rap analysis is supporting continued deepening
of the surface low. the low is currently centered near buffalo,
ny and will progress into the st. lawrence river valley this
evening, dragging a strong cold front southeast through the
region. all of northern ohio and nw pa are currently in the warm
sector and dry slot, with scattered rain showers and drizzle,
except for some rain/snow mix in far ne ohio and nw pa where
colder temperatures have hung on. this will not last much
longer, with regional radar loops showing a burst of snow along
the cold front in lower michigan and southwestern ontario
dropping into lake erie. expect a rapid changeover back to snow
late this afternoon and evening as this burst moves
southeastward through the region. this will occur between 19 and
20z along the i-75 corridor, 20 to 21z along the i-77 corridor,
and 21 to 22z in far eastern ohio and western pa. this will lead
to a quick coating of snow on roadways and visibilities dropping
to 1/2 mile or less at times during the evening commute, including
the greater cleveland and akron/canton areas. temperatures will
be below freezing areawide by 00z, so will need to watch for
black ice on untreated surfaces as well given the rainfall that
occurred today.

this will take us into the lake-effect portion of this event.
strong cold air advection in the wake of the front tonight and
thursday as the mid/upper trough axis digs through the great
lakes combined with broad cyclonic flow will generate a lake
response. an initial nw boundary layer flow tonight (about
310-320 degrees) will direct a lake huron connected band into nw
pa. there is uncertainty in the exact location of this band as
is always the case, but 850 mb temps falling to -13 to -14 c
combined with decent moisture and lift into the dgz support
snowfall rates up to 1 inch per hour at times under this band,
mainly in upslope portions of southern erie county, pa. it is
possible that the band clips ne crawford county, pa at times,
but given the uncertainty in how much the band will wobble, kept
crawford in an advisory since confidence in warning level snow
is higher in southern erie. outside of this huron band tonight,
there should be a lull most of the night. a 310-320 degree
boundary layer flow is a short fetch across lake erie, and this
combined with forecast soundings showing a lot of dry air and
subsidence will cause lake-effect to struggle farther west. we
will have to wait until during the day thursday when the flow
backs and moisture improves to see more organized bands develop
across the ohio snowbelt. rap and href guidance suggest a weak
mid-level impulse or two dropping through the southern great
lakes thursday, increasing moisture and lift as the flow backs,
and this combined with increasing south shore convergence
should get bands going east of cleveland and into pa, which will
gradually lift ne thursday afternoon through thursday night.
so, after the burst of synoptic snow with the cold front this
evening, additional lake-effect snow will mostly hold off until
thursday into thursday night, except for under the huron band in
pa.

with all of this being said, slightly lowered additional
snowfall to 1-3 inches in the higher terrain of eastern
cuyahoga, geauga, and southern ashtabula counties, with 1-2
inches near the lakeshore of cuyahoga and ashtabula counties and
in lake county. locally up to 4 inches could fall in geauga and
southern ashtabula counties. generally 1-2 inches is expected
across ne medina, northern summit, portage, and trumbull
counties. kept forecasted additional snow similar to previous
forecasts in nw pa, with 5-10 inches (locally up to 12) in much
of southern erie county and 3-6 inches in much of crawford
county (highest ne part of the county). the erie pa lakeshore
will be in the 1-3 inch range. based on these updates, the
advisories continue to look good in geauga, southern ashtabula,
and crawford counties, with a solid warning in erie county. the
lake-effect bands will gradually lift into western ny late
thursday night into friday morning as the flow backs.

temperatures will rapidly fall into the upper teens to low 20s
tonight, with highs in the mid 20s to low 30s thursday. lows
thursday night will fall into the mid teens to low 20s.

&&

.short term /friday through saturday night/...
the persistently cold and wintry pattern will continue unabated
through the weekend as the mid/upper pattern across north
america further amplifies, with anomalous western conus and
alaskan ridges and a deep eastern conus trough below an
elongated polar vortex near hudson bay. this is a classic cold
pattern for central and eastern portions of the u.s. as repeated
shots of arctic air drop through the region. within this cold
and active nw flow pattern will be a series of clipper systems.
the first clipper will dive from the upper midwest late thursday
night through the ohio valley friday. deterministic and ensemble
guidance are finally starting to come into better agreement on
its track, and the bulk of the snow should stay south of our
cwa. however, areas along and south of u.s. 30 could see up to
0.5 inch of snow friday. w flow behind this first clipper will
then slowly push lake-effect snow showers back towards lakeshore
areas of far ne ohio and nw pa friday night. a second and
stronger clipper will then quickly follow saturday into saturday
night, and this one has the better chance for areawide synoptic
snow. details are still uncertain, but probabilities for at
least 1 inch of snow in most areas are increasing saturday into
saturday night. an arctic cold front will be dragged down behind
this clipper as the trough deepens across the great lakes once
again, so additional lake-effect snows are likely late saturday
into sunday. depending on wind direction and moisture, this
could be significant for the primary and possibly parts of the
secondary snowbelt.

highs will remain in the upper 20s to low 30s friday, cooling
into the low to mid 20s saturday. lows friday night will fall
into the teens areawide, with single digits away from the lake
saturday night. wind chill values will fall below zero in most
areas saturday night, so this is very impressive cold for mid
december! in fact, these air temperatures are 15-20 degrees
below average.

&&

.long term /sunday through wednesday/...
the deep arctic airmass and lake-effect snow showers will
continue sunday before finally trying to end monday as high
pressure slowly builds in from the midwest. this high will slide
across the mid atlantic tuesday and wednesday as the mid/upper
flow turns zonal, and this will signal at least a temporary
break from the cold pattern as pacific based air is carried
east. the next low approaching by mid week will actually bring
rain as temperatures warm from the teens and 20s sunday and
monday to the upper 30s to low 40s by wednesday.

&&

.aviation /18z wednesday through monday/...
a brief lull in rain/snow is likely across most of the area at
the very start of the taf period, however a strong cold front
will enter the northwestern fringe of the cwa within the next
couple of hours and push a burst of snow southeast across the
local area between about 19z and 00z. snow will likely end at
ktol/kfdy/kmfd near or shortly after 00z with lake-enhanced snow
showers continuing across ne oh/nw pa through midnight. lake-
enhanced precip may dwindle a bit late tonight, however a
primary band of moderate lake-enhanced snow will likely develop
downwind from lake huron somewhere in ne oh/nw pa overnight
before lifting northeast as flow backs to the west by early
thursday morning. this could push the band of snow and lower
visibilities over keri at some point between 04z and 09z
thursday. additional lake effect snow showers will most likely
develop thursday morning, resulting in increasing snow chances
across the remainder of the snowbelt region (including kcle and
kyng).

flight conditions will be somewhat variable across the area
tonight through 18z thursday with vfr likely developing at
persisting at ktol and ceilings fluctuating between vfr and mvfr
outside of lake effect snow/clouds. terminals that experience
lake effect snow/clouds will generally have mvfr conditions in
lower ceilings/visibilities, however there may be periods of ifr
conditions in any localized bands of moderate snow.

winds will shift from the west to the northwest behind the cold
front this evening and breezy conditions with sustained winds to
12 to 17 knots and gusts to 25 to 30 knots are expected through
this evening. winds will diminish slightly to 10 to 15 knots
with gusts to 20 to 25 knots tonight before becoming more
westerly and diminishing to 8 to 14 knots with gusts to around
20 knots during the day thursday.

outlook...non-vfr is expected in periods of lake effect snow
through thursday night. additional non-vfr is likely in periods
of snow as a series of systems cross the area friday through
the weekend, best chance across ne oh and nw pa.

&&

.marine...
marine headlines will likely be needed for the majority of the late
week/weekend period as a series of systems cross the local area. a
cold front will continue to cross the local area late this afternoon
into this evening, allowing winds to shift to the northwest in its
wake. a gale warning remains in effect for the open and
nearshore waters from reno beach east until 00z/7 pm this
evening. northwest gales will diminish to 20 to 30 knots tonight
with winds diminishing to 15 to 20 knots in the western basin
early thursday morning. flow becomes more westerly during the
day thursday and winds will remain elevated in the eastern and
central basins before winds diminish to 10 to 15 knots late
thursday night into friday. winds are expected to shift to the
west/southwest by friday night before increasing to 20 to 30
knots on saturday and shifting to the northwest saturday night
through late sunday. winds should diminish early next week.

.key messages...

- colder air returns with 1-2" of lake effect snow possible this
evening in northwest in and southwest mi.

- more light snow is expected this weekend, along with very cold
air. wind chill values may drop below -10f sunday morning.

a trailing cold front, currently near the us 24 corridor as of 18z,
will continue southeast clearing the rest of our forecast area by
early this evening. associated convergence under weakened
deformation will allow for light precipitation (rain changing to
light snow) to accompany this feature with little to no snow
accumulation.

attention then turns to marginally favorable conditions for les late
this afternoon into tonight as 850 mb delta t`s push 20 in colder
northwest flow. the overall moisture quality and meager 5-6 kft
inversion heights doesn`t really favor a sustained vigorous lake
response, though the cloud layer does reach into the dgz for
localized 1-2" snows and minor travel impacts in favored nnw flow
snow belts.

cold northwest flow will send a couple more clippers southeast
through the midwest and ohio valley late this week into the weekend.
these appear to be your more classic clippers that have relatively
narrow snow swaths (2-5"). a model consensus favors the thursday
night wave and heavier fgen snow to bypass just southwest of the
area, though still possibly clipping areas mainly southwest of us 30
with a quick 1-2" of snow. still some wriggle room left for a slight
north or south tick. another clipper then follows through saturday
afternoon-night with additional snow chances, followed by les and
sub-zero wind chills sunday into sunday night. this cold/wintry
pattern then finally breaks down next week.

an upper-level trough axis is now east of lake michigan which
has resulted in a decline of organized lake effect snow. as a
result, have backed off the magnitude (intensity) of the les at
ksbn and have narrowed the time frame for lake effect snow
showers to impact kfwa. passing snow showers may come and go at
ksbn until the low-level wind profile backs slightly to the
west as the evening progresses. beyond the first 4-6 hours of
this taf period, lake effect is poised to struggle to persist at
kfwa not only due to the anticipated backing flow but rising
inversion heights as well.

medium-high confidence in vfr ceilings thursday afternoon as
drier air briefly moves in.

.key messages...

- temperatures will drop into the teens and 20s tonight.

- a reinforcing shot of arctic air will arrive this weekend, sending
wind chill readings into the single digits. sub zero wind chills
are expected sunday morning.

- there is a chance for a warming trend during the end of the
forecast period; tuesday into next wednesday.

.aviation...

post frontal northwest winds have taken over southeast michigan this
evening with a mix of mvfr and low vfr ceilings. gusty winds of 25
to near 30 knots will be possible for the next hour or so with gusts
then decreasing towards 20 knots through about 07z tonight. drier
air is bringing these areas of low vfr ceilings, but expect the lake
connection to maintain a decent coverage of mvfr ceilings along with
isolated to scattered vfr snow flurries into tonight. mvfr to low vfr
ceilings look to hold through much of the day tomorrow as winds
become more westerly during the afternoon. mbs stands the best chance
to see better scattered light snow showers continue during the first
half of the day, but confidence too low to mention at this time given
the more westerly wind component.

for dtw...light snow eventually tapers off later this evening, but a
rapid drop in temperatures into the low 20s is expected with any
leftover liquid on surfaces expected to freeze on any untreated
surfaces.

dtw threshold probabilities...

* high for ceiling at or below 5000 ft through early wednesday
morning. then medium through remainder of the day.

* moderate for exceeding crosswind threshold from 300-330 direction
through 01z this evening.

remnant mid level deformation associated with the departing upper
wave will continue to rapidly weaken during the remainder of the
afternoon as slight mid level ridging/brief mid level negative
vorticity advection takes hold. this will bring an end to residual
precip by early evening. ongoing post frontal cold air advection
within the gusty nnw winds will send temps into the 20s this
evening, likely resulting in freezing of untreated wet surfaces. the
advisories will be expired at 4 pm, with any potential evening
freeze up being addressed through special weather statements.

cold air advection will persist through the night under continued
northwest winds. a closed mid level low over ne ontario will track
into srn quebec by thurs afternoon. the circulation associated with
this feature is what is driving the colder back across the region.
lake effect activity within the northwest flow tonight will largely
remain out of se mi aside from a few stray snow showers into the
thumb. the low level flow will back more westerly on thursday.
limited inversion heights and an overall dry ambient airmass across
srn lake mi will inhibit snow shower activity into se mi. the
expectation for at least some strato cu under the inversion and
given 925mb temps forecast around -9c will warrant forecast highs
mainly in the mid to upper 20s.

model solutions all indicate a good feed of pacific moisture
tracking from the canadian rockies into the ohio valley friday into
saturday along the upper jet axis. a couple of short waves embedded
within the flow and along a decent baroclinic zone will support at
least a couple rounds of snow for mainly the ohio valley thurs
night, then again saturday/saturday night. recent model runs have
trended farther south with these systems, suggesting only a low
chance that the northern edge of these system will brush the
southern portions of se mi. an elongated upper low is forecast to
advance across the northern lakes fri night into saturday. the lead
edge of the mid level height falls will pass over lower mi friday
night. a brief interval of deep layer moisture moisture along a weak
surface front and lake mi enhancement will support the next chance
for show friday night into saturday morning. a brief interval of
higher intensity snow showers off lake mi is possible late fri
night/saturday morning before much drier air limits the inland
extend of lake enhancement. forecast amplification of this upper low
across the great lakes over the weekend is expected to drive arctic
air across the region. this will warrant well below normal
temperatures (with single digit and some sub zero wind chills) which
will last into monday. medium range model and probabilistic guidance
suggests a more notable warming trend possible tues into wed of next
week.

marine...

low pressure has pushed through the area and is now located over
lake ontario. the low pulled a cold front through this afternoon
which allowed a cold airmass to surge in behind the front within the
northwesterly flow causing a period of gales across southern lake
huron and the connecting nearshore zones. though the general trend
late this afternoon has been for less frequent gusts to gales, there
are still enough observations to keep the gale warning in effect as
we head into the evening hours to which we`ll revisit this evening
to see if we can cancel them a little early. waves will continue to
remain elevated through the overnight and into thursday so we`ll
have to transition to small craft advisories at some point. surface
ridge building in for thursday evening/night will lead to much
lighter winds, which should linger into friday as a wave of low
pressure track through the ohio valley. none-the-less, an arctic
front is on track to move through friday night, with sporadic gusts
to gales possible over lake huron during the weekend as 850 mb temps
plummet to -20 c, supporting snow squalls and freezing spray as
well.
