What forecasters said that day

The local office's own words before this severe thunderstorm 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 severe thunderstorm warning went out at Jul 6, 4:09 PM EDT, 26 minutes earlier.

Area forecast discussion, Jul 6, 4:09 PM EDT, 26 minutes before

Area Forecast Discussion
National Weather Service Cleveland OH
409 PM EDT Thu Jul 6 2023

.SYNOPSIS...
A cold front will move east across the area through tonight,
followed by high pressure for Friday. A low pressure system will
arrive across the Ohio Valley on Saturday into Sunday, followed
by high pressure once again for early next week.

&&

.NEAR TERM /THROUGH FRIDAY NIGHT/...
Scattered to widespread showers and thunderstorms continue
across the area this afternoon, although the most intense
convection appears confined to along and east of the I-77
corridor, associated with a pre-frontal boundary and coincident
with a strong DCAPE gradient and steep low-level lapse rates.
The strongest wind gusts so far today have generally been in the
40 to 50 mph range. Heavy rain with rainfall rates in excess of
2 inches per hour will remain possible with the strongest
thunderstorms through sunset. The actual cold front appears to
be working its way southeast across Michigan this afternoon,
although the remaining shower/thunderstorm activity behind this
pre-frontal trough appears to pack much less of a punch, given
the weak thermodynamic environment in play.

For tonight, shower and thunderstorm activity will generally
diminish following sunset with the exception of along the cold
front where rain chances may persist, especially across NE OH/NW
PA and along the lakeshore.

Much more comfortable and quieter weather is anticipated for
Friday with dew points lowering into the upper 50s. Highs will
be near to slightly below average in the upper 70s to lower 80s
under mostly sunny skies.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
High pressure moves east of the region allowing low level
moisture to return by the afternoon. Approaching upper level
trough and a weak cold front should provide lift to the region.
It looks like scattered to numerous showers/thunderstorms
develop by late afternoon then spread eastward across the
region. We will need to monitor for some locally heavy rainfall
across the region. Any remaining showers/thunderstorms end from
west to east with the weak cold frontal passage. High pressure
spreads into the area by Sunday night with dry conditions expected.
Temperatures should be slightly cooler than seasonal averages
through the short term.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
High pressure moves west to east across the region through
Monday night. Lots of uncertainty on when the next cold front
arrives as ripples of low pressure move through the trough that
reaches southward to the Northern Plains to Central Great Lakes.
The trough and the approaching cold front will interact with the
increased low level moisture bringing increased
shower/thunderstorm chances to the region Tuesday and beyond.
Best chances appear to be Wednesday night into Thursday.
Temperatures should return to near or slightly above seasonal
averages.

&&

.AVIATION /18Z Thursday THROUGH Tuesday/...
Mainly VFR across the TAF sites early this afternoon, although
scattered to widespread showers and thunderstorms are
developing across the eastern half of the area which could
briefly result in MVFR to IFR conditions. As a cold front moves
south across the lake overnight, ceilings will quickly drop to
MVFR and IFR at all TAF sites except for TOL/FDY. Isolated
pockets of LIFR are also possible late tonight into early Friday
morning. Conditions should quickly improve to VFR areawide by
mid to late morning.

Winds are generally out of the south to southwest early this
afternoon, 5 to 10 knots. Any thunderstorms that impact the TAF
sites have the potential to produce gusty winds of 25 to 35
knots. Winds will shift towards the west and northwest, becoming
generally northerly behind the cold front late tonight into
tomorrow.

Outlook...Non-VFR possible in scattered showers and
thunderstorms Saturday into Sunday.

&&

.MARINE...
A cold front will cross Lake Erie this evening. In the wake of
the front northerly winds increase to 10 to 15 knots with waves
building to 2 to maybe 4 feet. Currently think we can keep the
RIP current risk low but will need to monitor closely. High
pressure builds into the region Friday with winds becoming
light. Winds swing around to the east and increase on Saturday
but should remain under 15 knots. Winds lighter from an easterly
direction for Sunday.

&&

OH...None.
PA...None.
MARINE...None.
