What forecasters said that day
The local office's own words before this winter weather advisory 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 winter weather advisory went out at Feb 14, 12:47 AM EST, 3 hours 20 minutes earlier.
Area forecast discussion, Feb 14, 12:47 AM EST, 3 hours 20 minutes before
Area Forecast Discussion
National Weather Service Cleveland OH
1247 AM EST Sun Feb 14 2021
.SYNOPSIS...
Weak upper level troughing will continue to move over the
Great Lakes through tonight. An Arctic high pressure will move
southeast across the Midwest into the Ohio River Valley region
Sunday and persist into Monday. Low pressure originating along
the Gulf Coast will track up the East Coast, impacting the Ohio
River Valley Monday into Tuesday. High pressure will build in
across the area on Wednesday. Another potential low pressure
system may impact the region towards the end of the week with
more unsettled weather.
&&
.NEAR TERM /THROUGH TODAY/...
Below-normal temperatures persist through the near-term. A 925
to 850 mb shortwave trough over eastern OH and vicinity late
this evening moves eastward to central NY/PA and vicinity by
daybreak Sunday. Simultaneously, a weak surface low moves
northeastward from southwestern PA to central NY. Isolated to
scattered light snow ahead of the shortwave trough should exit
far-eastern OH and northwest PA by around midnight tonight. Some
freezing drizzle may mix with this snow due to the potential
for continued loss of the seeder-feeder process and lingering
low-level clouds remaining marginally-cold for ice nucleation.
In other words, low-level cloud top temperatures hover near
negative 10C. Patchy freezing fog may develop overnight tonight
and continue through about daybreak since nocturnal cooling may
allow low-level cloud cover to expand downward to the surface.
Of note, low-level winds will back from northerly toward
northwesterly across Lake Erie through Sunday morning. Light
lake effect snow showers may stream off ice-free portions of
the lake and affect the snowbelt. Some freezing drizzle may mix
with the snow since lake effect clouds may become too warm to
support ice nucleation at times. Lake effect precip should end
by late Sunday morning as drier air overspreads the region and
causes weak lake-induced CAPE to wane. Any additional snow
accumulations in our CWA should be less than a half inch. Any
ice accumulations should be a very thin glaze.
High pressure attempts to build from the northern Great Plains
through Sunday night. Aside the aforementioned snow, fair
weather is expected through the day on Sunday. Overcast skies
will continue with high and mid-level moisture increasing from
the southwest ahead of the next storm system. The next round of
accumulating snow arrives late Sunday night into Monday morning,
just in time for the morning commute. Up to an inch or two of
fresh snow should accumulate by daybreak.
&&
.SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT/...
Deep digging upper level trough through the Central Plains states
will gradually shift east and become negatively tilted slightly.
This will result in surface low pressure over the delta region of
the Mississippi River to move northeast toward West Virginia by
Monday evening followed by a secondary stronger low pressure system.
The first low will be in response to an upper level positive
vorticity maximum sliding into the southern Great Lakes region and
then the secondary low deepens as the upper trough becomes more
negatively tilted. Model guidance is in general agreement that
periods of steady of heavy snow will affect our forecast area
Monday through Tuesday morning. Issued a Winter Storm Watch for
most of our CWA, except our northwest OH counties. The watch
runs from 7 AM Monday to 1 PM EST Tuesday. Within the watch, a
widespread snowfall of 5 to 9 inches is possible. At this point,
the greatest snow accumulations may occur essentially along and
east of the I-71 corridor. This is where heavy snow banding
tied to frontogenesis and isentropic lift in a TROWAL may occur.
The low pressure system will move out of the area Tuesday allowing
large area of high pressure to to move southeast into the Great
Lakes region. This will bring a return back to fair weather for late
Tuesday night. As the high settles into the area Tuesday night,
temperatures will fall to around zero across the western half of the
area and even colder in the normal cold spots. Single digits
expected in the east. Winds and the cold temperatures will support
wind chill values down to around -5 degrees late Tuesday night and
may need a headline for the cold wind chill values.
&&
.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
Broad upper level ridge will build northeast across the area
Wednesday and bring a short break to the local area with a return
back to fair weather. The upper level ridge will support a large
area of high pressure over the central Great Lakes region Wednesday.
Amplification of the upper level ridge will take place as it shifts
off the East Coast Thursday and Thursday night. Yet another deep
digging positively tilted trough will dive into the Central Plains
Wednesday night into Thursday. The trough will make an attempt to go
negatively tilted Friday. A surface low will develop over far
southern Texas and extend a surface warm front northeast to the Ohio
Valley by Wednesday night where it will become nearly stationary.
This surface low is expected to follow a similar track as the
Monday/Tuesday low and move northeast to the Carolinas by Friday
night. A secondary surface low will develop over the Delmarva region
and the surface low should jump to the coast. A trough will extend
north across the forecast area Thursday night and once again, it
appears our forecast area will remain on the northern edge of the
precipitation. The longer range models differ considerably on the
track of the late week surface low pressure. The GFS takes the
surface low north into the central Great Lakes and pumps considerably
warmer air into the area by Thursday. The Canadian model follows the
same trend with coastal low development and in this scenario surface
low could jump to the East Coast. Will follow continuity and lean in
the direction of the European model with this update. Cold air
advection will follow the low passage by Friday night into Saturday.
So, expect more accumulating snow and a slight warmup by Thursday.
&&
.AVIATION /06Z Sunday THROUGH Thursday/...
There is a mix of ceilings and visibilities currently across the
area, which is likely to remain the case through 13Z Sunday. As
a weak surface low continue to track east out of the area, high
pressure is expected to build in behind it, allowing
northwesterly winds of 5 to 10 knots become light and variable
from the north by Sunday afternoon. This transition period will
also be marked by low level moisture lingering through Sunday
morning. This has allowed widespread low level clouds to
develop, dropping some terminals to LIFR ceilings at times. For
the remainder of the night, the primary concern is that the
diurnal cooling will aid in the low level stratus descending to
the surface and patchy fog developing. The level of uncertainty
is rather high with this occurring so opted to not mention it
in the TAFs at this point.
Additional weather concerns exist for KYNG and KERI as northerly
winds may allow for some lake enhanced precipitation to develop
and move inland. Clouds temperatures are lingering near negative
10C which likely result in a mix of snow and freezing drizzle in
anything that develops into the morning hours. By late
morning/early afternoon Sunday, ceilings should begin to lift
and become widespread MVFR. These conditions will linger into
the overnight hours ahead of the next chance of snowfall.
Currently, only KCLE has snowfall in the TAF, but most terminals
will likely see snow showers within the next forecast update.
Outlook...Non-VFR likely with periods of widespread snow Sunday
night through Tuesday. Additional non-VFR are possible with
widespread snow Tuesday night and again Wednesday night into
Thursday.
&&
.MARINE...
Northeast winds continue on the lake at 15 to 25 knots. Much of the
central and western portions of the lake remain ice covered with
considerable open water on the eastern basin. The nearshore waters
are ice covered as well. The northeast winds continue to help erode
the rapid thin ice cover that developed over the past week. Winds
will quickly diminish overnight tonight and become northwest by
morning. Light winds out of the north-northwest will persist through
Sunday night and increase again out of the north ahead of the next
storm system that is expected to move northeast toward the Virginias
and then off the East Coast Tuesday. High pressure will build in
from the west Wednesday and winds will diminish to light northeast.
An increase to 15 to 25 knots is expected Wednesday night as yet
another low pressure system moves northeast toward the area
Thursday.
