  north of I-90 increasing to 12 to 20 inches with locally higher 
  amounts south of I-90. Wind gusts up to 60 MPH north of I-90 and 
  up to 50 MPH south of I-90, mainly Thursday morning.

* WHERE...Northern Erie and Southern Erie Counties.

* WHEN...Until 1 AM EST Saturday.

* IMPACTS...Visibilities will drop below 1/4 mile due to falling and 
  blowing snow. Significant drifting of snow is likely, including 
  across some roadways. The strong winds may cause downed trees and 
  power outages. Whiteout conditions are expected and will make 
  travel treacherous and potentially life-threatening. Travel is 
  expected to be impossible late tonight and Thursday and should be 
  postponed. The hazardous conditions will impact the Thursday 
  morning and evening commutes.

* ADDITIONAL DETAILS...An Arctic front will cross the region tonight 
  and will bring a band of heavier snow with quickly deteriorating 
  conditions, including a quick inch or two of snow, visibility of 
  1/4 mile or less, and wind gusts to 50 mph. Travel could quickly 
  become difficult across the region with the onset of this winter 
  event. The strongest winds and blizzard conditions are expected 
  late tonight through midday Thursday. Lake effect snow bands will 
  develop Thursday afternoon and be the main concern for the rest of 
  the event through Friday as wind gusts slowly diminish. The strong 
  winds and density of the large snowpack across Northwest 
  Pennsylvania could result in damage to structures.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Travel should be restricted to emergencies only. If you must travel, 
have a winter survival kit with you. If you get stranded, stay with 
your vehicle.

The Pennsylvania Department of Transportation and Pennsylvania

146 PM EST Thu Dec 5 2024

...BLIZZARD WARNING REMAINS IN EFFECT UNTIL 1 AM EST SATURDAY...

* WHAT...Blizzard conditions. Additional snow accumulations between 
  8 and 14 inches. Winds gusting as high as 45 mph.

* WHERE...Northern Erie and Southern Erie Counties.

* WHEN...Until 1 AM EST Saturday.

* IMPACTS...Visibilities will drop below 1/4 mile due to falling and 
  blowing snow. Significant drifting of snow is likely, including 
  across some roadways. The strong winds may cause downed trees and 
  power outages. Whiteout conditions are expected and will make 
  travel treacherous and potentially life-threatening. Travel is 
  expected to be impossible today and should be postponed. The 
  hazardous conditions will impact the Thursday evening commute.

* ADDITIONAL DETAILS...Lake effect snow with the strongest winds and 
  blizzard conditions of the event will continue through this 
  evening. Lake effect snow bands will persist and be the main 
  concern for the rest of the event through Friday as wind gusts 
  slowly diminish. The strong winds and density of the large 
  snowpack across Northwest Pennsylvania could result in damage to 
  structures.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Travel should be restricted to emergencies only. If you must travel, 
have a winter survival kit with you. If you get stranded, stay with 
your vehicle.

The Pennsylvania Department of Transportation and Pennsylvania 
Turnpike Commission strongly encourage motorists to heed all travel 
restrictions and delay unnecessary travel. Visit www.511pa.com for 
the latest travel, roadway, and traffic conditions.

Persons should consider delaying all travel. Motorists should use 
extreme caution if travel is absolutely necessary.

A Blizzard Warning means severe winter weather conditions are 
expected or occurring. Falling and blowing snow with strong winds 
are likely. This will lead to whiteout conditions, making travel 
extremely dangerous. Do not travel. If you must travel, have a 
winter survival kit with you. If you get stranded, stay in your 
vehicle.

What forecasters said that day

The local office's own words before this blizzard warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Cleveland, OH wrote its last area forecast discussion before this blizzard warning went out at Dec 4, 7:00 PM EST, 2 hours 20 minutes earlier.

Area forecast discussion, Dec 4, 7:00 PM EST, 2 hours 20 minutes before
Area Forecast Discussion
National Weather Service Cleveland OH
700 PM EST Wed Dec 4 2024

.SYNOPSIS...
Strong low pressure system glides across the Great Lakes region
while dragging a cold front across the local area. Lingering
troughing will remain across Lake Erie for Thursday before high
pressure builds overhead from the west to end the week and begin
the weekend.

&&

.NEAR TERM /THROUGH THURSDAY NIGHT/...
Key Messages for the next 36 hours and beyond:
- A multi-hazard winter storm is entering the region this
  evening with winter weather and wind hazards impacting the
  local area.
- The onset of snow across the area will be quick and
  significant as an Arctic front is expected to move through
  the area this evening. This front will be guided into the area
  with a band of heavy snow that will cross the entire area,
  starting in the I-75 corridor of Northwest Ohio around 9 PM to
  far Northeast Ohio and Northwest Pennsylvania after Midnight.
- This band of snow will feature quickly deteriorating
  conditions, including a quick inch or two of snow, visibility
  of 1/4 mile or less, and wind gusts to 50 mph. Travel could
  quickly become difficult across the region. This threat may
  need to be messaged further with Special Weather Statements or
  perhaps Snow Squall Warnings tonight.
- Behind the Arctic front, the lake effect snow machine returns
  with a broad area of the primary and secondary snow belt of
  Northeast Ohio and Northwest Pennsylvania receiving warning
  and advisory level accumulating snowfall. Snow will be very
  dependent on where bands persist in the west to northwest
  flow, higher terrain/the upslope component to the lake effect,
  aid from upstream connections from other Great Lakes, and
  strength of the wind of the boundary layer.
- A Lake Effect Snow Warning has been issued for Erie and
  Crawford Counties in PA and Ashtabula County, Ohio from 4 PM
  today to 1 AM Saturday. The remaining Lake Effect Snow Warning
  and Winter Weather Advisories are valid from 4 PM today to 4
  AM Friday.
- Winds will continue to be strong behind the Arctic front
  tonight into Thursday, especially near the lakeshore. Winds
  will allow for blowing snow, low visibility, and could damage
  trees and power lines. Additionally, the gusty winds and
  density of the large snowpack across far Northeast Ohio and
  Northwest Pennsylvania could result in damage to structures.
- Numerous marine hazards are discussed in the below Marine
  section, as a Gale Warning and Low Water Advisory have been
  issued for Lake Erie.

Meteorological Discussion:
Deepening low pressure will continue to glide across the Upper Great
Lakes region as its accompanying upper trough digs across the Lower
Great Lakes region this evening and overnight. Ahead of the passage
of the trough axis, embedded shortwaves and a strong LLJ have moved
overhead the region. The LLJ, characterized by 850mb wind speeds
roughly between 50 and 55 knots has led to surface southwesterly
wind gusts between 25 and 35 MPH with isolated gusts of 40+ MPH.
Additionally, the embedded shortwaves have supplied enough upper
level support for light returns on radar this afternoon with a few
reports of light rain/snow showers reaching the surface. Anticipate
for this band of rain/snow showers to continue through the evening
ahead of the frontal passage.

The surface cold front will enter western zones late tonight with an
efficient band of snowfall developing along the cold front and
moving east across the local area overnight tonight. Given the
strong wind gusts, pre-existing snowpack, and additional quick
burst of snowfall associated with the Arctic front, can't rule out
snow squalls across portions of the forecast area during the
overnight hours. Snow squalls can produce rapid visibility drops to
a quarter mile or less with deteriorating road conditions making
travel extremely dangerous and difficult. With the initial burst of
snow, generally expecting a trace to 3 inches for most of the
region, locally higher amounts across the Snowbelt between 2-4
inches through Thursday morning.

The cold front will be out of the forecast area by Thursday morning
with mean layer flow becoming northwesterly across a relatively warm
Lake Erie. The front will usher in a much cooler airmass with 850mb
temperatures dropping to -10C to -15C by Thursday. As such, any
additional snowfall Thursday onward will be more lake effect in
nature. Lake effect snow showers will persist through the end of the
near term and into the beginning of the short term. Lake Effect Snow
Warnings for Cuyahoga, Lake, Geauga, Summit, Portage, Trumbull
remain in effect through 4 AM EST Friday with the Lake Effect Snow
Warning for Ashtabula County, Ohio and Erie and Crawford Counties in
Pennsylvania through 1 AM Saturday. Outside of the traditional
snowbelt, have Winter Weather Advisories in place for Lorain,
Medina, and Mahoning Counties through 4 AM Friday. Total snowfall
amounts from lake effect will generally range between 4-8 inches,
with locally higher amounts in excess of 12 inches where snow
bands persist and across higher terrain locations.

Northwesterly wind gusts remain elevated, especially along the Lake
Erie lakeshore, behind the passage of the cold front on Thursday.
These winds, in addition to the additional snowfall amounts and
dense snowpack, may result in blowing snow and reduced visibilities
across the Snowbelt during the Thursday morning commute.

With the passage of the Arctic front, temperatures will quickly drop
into the upper teens to lower 20s overnight tonight. Gusty winds
will lead to wind chill values dipping into the single digits to
near 0 degrees by early Thursday morning. Areawide high
temperatures on Thursday remain below freezing with overnight lows
Thursday night once again settling in the teens to low 20s.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
Lake effect bands should be a bit more transient Friday as flow
starts off northwesterly Friday morning before becoming more
westerly during the afternoon and southwesterly Friday night. There
may be a slight lull in snowfall rates Friday morning into the early
afternoon, but generally expect the heavier snowfall rates to occur
wherever a band with an upstream connection to Lake Huron sets up
(likely NW PA). However, an uptick in snowfall rates and coverage
will likely occur Friday afternoon and evening as a shortwave dives
southeast across the eastern basin of Lake Erie. A burst of moderate
to heavy snow will likely occur across NW PA and possibly into
extreme NE OH at some point between roughly 18Z Friday and 06Z
Saturday, but at this point flow will likely be westerly so the
majority of the snowfall may be confined to the higher terrain of NW
PA, especially Erie County. Any remaining lake effect snow should
begin to shift north and possibly over the lake as flow becomes more
southwesterly, but lake effect showers may continue well into
Saturday if flow is slower to change, especially since guidance is
hanging onto moisture over the eastern basin of the lake through
most of Saturday. Either way, snowfall rates should be on the
decline Saturday since upstream moisture will be dwindling. Dry
weather returns as high pressure builds over the region Saturday
night and 850mb moisture peters out.

In terms of additional snow accumulations Friday through Friday
night, Erie and Crawford counties in PA will likely see 5 to 8
inches with the highest amounts likely across the higher terrain of
Erie County. Several inches of snowfall are possible in the
remainder of the primary snowbelt region, but accumulations will
depend on where bands of snow set up.

Temperatures will be in the upper 20s to lower 30s Friday with wind
chills in the teens expected during the day. Expect overnight lows
in the upper teens to lower 20s. A warming trend will begin to
unfold Saturday with highs in the upper 20s to mid 30s and overnight
lows in the mid to upper 20s to near 30 degrees anticipated.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
High pressure will briefly settle over the area Sunday and expect
one day of dry weather (and at least some sunshine!) before an
unsettled weather pattern once again unfolds late Sunday into next
week. On Monday, a shortwave trough/warm front will lift across the
region with PoPs increasing ahead of and especially behind the warm
front Sunday night into Monday morning. Meanwhile, a deep trough and
surface low will move east towards the region with its associated
cold front crossing the area Tuesday. There's still quite a bit to
iron out with the track/intensity of the low and the speed of the
cold front, but widespread showers are likely Monday with lake-
enhancement/effect more likely behind the cold front Tuesday into
Wednesday.

Warm air advection will allow temperatures to rise into
the 40s Sunday and upper 40s to lower 50s Monday and Tuesday so
expect rain for the majority of the event. However, there may be a
rain/snow mix or a brief transition to snow Tuesday night and
possibly Wednesday as temperatures cool into the 30s. The warmer
temperatures will result in at least some melting of the (currently
substantial) snowpack across far NE OH and NW PA and this in
combination with about an inch of rainfall between Sunday night and
Tuesday night could result in flooding concerns for both rivers and
low-lying/poor drainage areas across the snowbelt region.

&&

.AVIATION /00Z Thursday THROUGH Monday/...
A mix of mainly MVFR and some VFR due to ceiling and visibility
restrictions as some stratus and rain/snow showers move through
the area ahead of an arctic front. This front will blast through
the area from west-east between 2-7z. A snow squall is expected
to evolve along the front, bringing vsby restrictions to IFR or
lower for generally an hour or less, along with a quick hit of
35-45kt wind gusts. Behind the front, MVFR ceilings are expected
to prevail. There will be a brief break in snow right behind the
front, before lake-enhanced snow quickly resumes into Thursday.
Main impacts at ERI, with decent impacts at CLE, CAK, and YNG
too. ERI will likely see primarily IFR with some LIFR at times.
The other three will likely see a mix of MVFR and IFR, with
brief LIFR in heavier squalls. Western terminals will likely
see off and on snow showers from a combination of moisture from
Lake Michigan and a trough moving through during the day
Thursday, bringing some MVFR to brief IFR vsby. ERI is expected
to see 6-10" of snow through the day Thursday, with 3-6"
possible at YNG, 2-5" at CLE, and 2-4" at CAK. MFD may see 1-3",
with 2" or less at FDY and TOL. Where any snow accumulates it
will be able to blow around through Thursday.

Outlook...Non-VFR likely in snow to continue at ERI through
Friday night, and possibly into Saturday. Conditions may
occasionally dip to IFR at times. Elsewhere, non-VFR ceilings
may continue into Saturday.

&&

.MARINE...
Unsettled marine conditions will continue for the next few days.
Southwest winds 15 to 30 knots have been a bit slow to increase this
afternoon, but expect west/northwest gales to develop over the lake
as a cold front crosses the area tonight. A Gale Warning remains in
effect for the zones west of The Islands through 21Z Thursday and
east of The Islands through 00Z Friday. Westerly winds will allow
water levels in the western basin to plummet to as low as 2 feet/24
inches below low water datum (the critical mark for safe navigation
is currently 2 inches above low water datum) tonight through at
least Thursday morning and a Low Water Advisory remains in effect.
Water levels may attempt to improve slightly as winds become a tiny
bit more northwesterly Thursday morning, but don't anticipate
significant improvements until winds firmly shift to the northwest
Thursday afternoon.
