What forecasters said that day

The local office's own words before this special weather statement 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 special weather statement went out at Sep 8, 2:12 AM EDT, 1 hour 4 minutes earlier.

Area forecast discussion, Sep 8, 2:12 AM EDT, 1 hour 4 minutes before
Area Forecast Discussion
National Weather Service Cleveland OH
212 AM EDT Tue Sep 8 2020

.SYNOPSIS...
The cold front moving across the area this afternoon will settle
across central Ohio as a stationary front by tonight. This
boundary will linger across the area through Tuesday before
shifting back north. High pressure begins to build into the area
on Thursday and will persist over the area through Friday.

&&

.NEAR TERM /THROUGH TODAY/...
As of 8 PM, showers and thunderstorms have largely settled
south of the area but not before dropping a widespread 2-4
inches of rain with locally higher amounts across much of NE
Ohio. Showers and thunderstorms are still ongoing across Central
Ohio and will tend to lift back north as a warm front with
additional showers and scattered thunderstorms expected across
NW Ohio overnight. Counties along the I-75 corridor have mostly
received less than an inch of rain but there were pockets of
1-2" across Marion and Morrow counties and will need to monitor
additional rainfall in these areas.

Previous discussion...
By late evening, the cold front will settle south of us and
transition into a stationary front, allowing the storms to
diminish over the area temporarily. By late overnight/early
Tuesday morning, the boundary will lift northwestward along
with a surge of moisture, increasing the chance of showers and
thunderstorms west of I 71. Depending on the exact location this
pseudo warm front lifts through, some areas of patchy fog may
occur across the southern area as temperatures drop and winds
become calm. However this will depend on shower dissipation, so
opted to keep fog out of the forecast for this update as
confidence is low. By Tuesday afternoon, all showers will
dissipate and move out of the area and dry conditions will
move in for the remainder of the near term forecast.
Temperatures across the area today will likely not get as high
as originally forecasted due to cloud cover and widespread
precipitation, so opted to bump the highs down a few degrees but
maintained the upper 70s with highs tomorrow in the mid 80s.
Overnight lows will be in the mid 60s.

&&

.SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/...
As a deepening low continues to dig down the West Coast, across
our area on Wednesday, high pressure will begin to build across
the area and allow dry conditions to move in. The area will
remain on the east side of the deepening low, keeping the air
mass rather dry over us. There is a chance of PoPs on Thursday
morning/early afternoon associated with a weak cold front that
moves across the area. High temperatures on Wednesday will be in
the 80s before cooling down on Thursday into the 70s. Overnight
lows will be in the upper 50s to low 60s.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
The long term forecast still has ample uncertainty that remains
with it as models struggle to find a consensus of how to handle
the trajectory of the low pressure in the southwest. Latest
trends show the low pressure moving eastward, with the center
moving just north of the Great Lakes. Models vary significantly
with the strength of the low pressure by the time it arrives
into the Great Lakes region however. Opted to keep temperatures
more seasonal during this forecast period.

&&

.AVIATION /06Z Tuesday THROUGH Saturday/...
Mainly VFR across the TAF sites this morning, although some
pockets of MVFR ceilings will be possible over the next several
hours. The threat for -tsra seems to be diminishing this
morning across most TAF sites, although there remains a chance at
TOL/FDY through the morning. Not thinking widespread fog will
be an issue at TAF sites tonight with variable winds around 5 to
10 knots. However, cannot rule out some patches of fog through
the morning. Following this morning, looking like VFR conditions
should prevail across the TAF sites through the remainder of the
period, though can't rule out some patches of MVFR ceilings and
vsbys, especially across NW OH associated with showers and/or
thunderstorms.

Outlook...Non-VFR in patchy fog/low ceilings Wednesday night
through Thursday morning.

&&

.MARINE...
Winds across the lake have begun to weaken substantially, with
the strongest winds remaining in the eastern basin at 20 knots,
gusting to 25 knots, from the southwest. Expecting to let the
small craft advisory expire for the eastern basin in the next
hour as conditions seem to have calmed, but will continue to
monitor to make sure. Winds are expected to shift as the cold
front moves across the lake this evening and become fairly calm
across the lake. This frontal boundary will stall across central
Ohio this evening. They will then become northeasterly by
Tuesday morning at 10 to 15 knots as the stationary boundary
moves northward as a pseudo warm front on Tuesday. Water levels
in the western basin will need to be monitored for lakeshore
flooding potential. After this frontal passage moves through,
winds are expected to become light and variable into Wednesday.
Past Wednesday winds will again shift and become northerly at
10 to 15 knots, however current models have waves remaining
under 4 feet so no headlines are anticipated at this time.
