The local office's own words before this flash flood watch 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 flash flood watch went out at Sep 8, 1:51 AM EDT, 2 hours 18 minutes earlier.
Area forecast discussion, Sep 8, 1:51 AM EDT, 2 hours 18 minutes before
Area Forecast Discussion
National Weather Service Cleveland OH
151 AM EDT Sat Sep 8 2018
.SYNOPSIS...
A stalled frontal boundary will remain over southern Ohio
into Saturday. This boundary will lift north on Sunday and
direct the remnants of Tropical Storm Gordon into the area. This
low will move northeast to near Toledo by Sunday evening then
continue into southern Ontario by Monday.
&&
.NEAR TERM /THROUGH TODAY/...
Update...Adjusted POPs to account for area of rain moving
northeast along the stalled frontal boundary. Northern areas
along the lakeshore will see the least amount of rain while
further south is where the heavier rain will occur.
Original...Drier easterly flow will attempt to keep rainfall
over the southwestern portion of the County Warning Area (CWA).
This is where the lift from some warm advection ahead of low
pressure that is located over Arkansas will exist through
tonight. This may shift just south of the region on Saturday.
Models are hinting at some rain off of lake across NW OH
Saturday morning. The warm advection pattern will then set up
ahead of low pressure Saturday night with steady rain developing
overnight. The heaviest rain Saturday night will occur after
midnight. Since we are thinking later Saturday night we will
hold off on a flood watch. It will likely be issued Saturday
morning.
Humid conditions will continue through the near term. Lows in
the 60s. Highs Saturday upper 60s to lower 70s.
&&
.SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/...
It is shaping up to be a very very wet Sunday with widespread
moderate to heavy rain expected. The steadier precip will reach
NW PA by early afternoon and expect the rain to continue
unabated into the evening hours. The devil is in the details and
it is tough to tell where the corridor of greatest rainfall
will be. It will likely be somewhere over the local area so will
broad brush rain totals. Most locations should expect to see
around 2 inches of rain. Will not include any thunder mention
till late Sunday. By that time the surface warm front will be
moving across the area causing surface dewpoints and instability
to briefly surge. The threat for embedded thunder will continue
till the trailing surface cold front crosses the area on Sunday
night. The area will begin to dry out from west to east on
Monday behind the front. Some instability showers in the wrap
around flow are possible on Monday but by Monday evening the
western end of the area should be dry. Will try to dry the
remainder of the area out on Tuesday but there should be plenty
of clouds. Given the amount of rain and clouds expected it will
be a cool period. Have used a blend of guidance for temps.
&&
.LONG TERM /TUESDAY THROUGH FRIDAY/...
The end of the week should end up being relatively quiet. High
pressure will generally be across the region. Some light precip/QPF
is being painted by the models with a bit of an inverted trough, but
much has to be worked out with the models once we can get rid of
this weekend's weather system. Temperatures will be seasonable, with
lower 80s by the end of the week.
&&
.AVIATION /06Z Saturday THROUGH Wednesday/...
The beginning of a very messy situation is taking shape at this
time as a stalled frontal boundary becomes the focus for rain to
occur across the area. Moisture streaming in from the west and
south will keep the threat of rain going across the south
through the forecast period. A brief break will take place in
the north as front sags slightly south allowing for some drier
air to push into the region. Then, as remnant low pressure
system pushes northeast, a surge of moisture will move into the
region and bring lowering ceilings and a much better chance for
rain heading into tonight. Rain could be heavy at times toward
the end of the forecast period. Winds will be increasing through
the period as the gradient between the remnant low pressure
system and the high pressure to the north tightens.
OUTLOOK...Non-VFR possible through Monday.
&&
.MARINE...
It won't be a good weekend to be on the lake. Northerly winds
will become east to northeast tonight and increase. By late
tonight should have small craft conditions over most of the
nearshore. Will also need beach hazards. Strong easterly flow
will continue through Saturday night. On Sunday the flow will
become southeast as low pressure approaches from the southwest.
Speeds could briefly get to 30 knots on Sunday afternoon and
comfortable at this point not going with Gales. The low will
move over lower Michigan Sunday night with a warm front lifting
across the lake during the evening. Winds will flip to the south
for a brief time before becoming westerly behind the trailing
cold front. Westerly winds will begin to slowly diminish late
Monday and will become northwest by daybreak Tuesday. Light and
variable flow is expected for the end of the period as high
pressure builds over the region.
