Area Forecast Discussion
National Weather Service Cleveland OH
453 PM EDT Sun Aug 21 2022

.SYNOPSIS...
A slow moving low pressure system will move to the eastern Great
Lakes through Monday and maintain an unsettled weather pattern. High
pressure will build overhead through the mid-week period. The next
trough will approach from the north by Friday.

&&

.NEAR TERM /THROUGH MONDAY NIGHT/...
Surface analysis has a broad 1015mb low extending across eastern
Indiana/western Ohio with an upper level low nearly vertically
stacked overhead. Sufficient clearing earlier this afternoon allowed
the airmass to destabilize with ML CAPE values of around 1500 J/kg.
However convection over Central Ohio has produced a lot of cirrus
debris which has limited further destabilization across central
Ohio. Convection continues to fill-in across NW Ohio and closer to
the lakeshore and will continue to shift east through the evening.
In addition, the HRRR suggests additional convection will fill in
across SW Ohio where heating continues and may drift towards the
Central Highlands with time. As the upper trough continues to slowly
pivot eastward tonight, storm motion will continue to the
northeast. The one area where pops may end up being to high
could be across inland NE Ohio but will adjust with future
updates as needed. Broad rotation associated with the upper
level system, especially co-located near the better surface
convergence, has led to the development of several funnel clouds
in NW Ohio. While funnel clouds may occur, the overall tornado
threat remains low given the lack of stronger shear and storm
organization. Thunderstorms have maintained a relatively low
centroid making heavy rain a concern, especially where training
occurs with southwest to northeast storm motion. Pockets of
rainfall in excess of 2 inches is possible and flood products
may be needed, especially where heavy rain has occurred over the
last 24 hours. Will continue to monitor severe weather
potential but the threat remains fairly isolated given effective
shear values of only 20-30 knots. Most likely case would be if
a storm with a stronger core collapses.

Coverage of precipitation will decrease considerably as we move past
peak heating and mid-level dry-slot wraps in from the west. Where
breaks develop in the clouds overnight, patchy fog may develop with
light winds and a moist boundary layer. As the 850-700mb trough
pivots across eastern Lakes Erie towards dawn, we expect to see lake
enhanced showers move in off the lake. Fairly good coverage is
expected across the eastern forecast area again on Monday, with
coverage increasing with daytime heating. Both temperatures and
instability will be a little lower with the cooler airmass overhead
on Monday. Chances for showers will become increasingly confined to
just off the far east end of Lake Erie on Monday night.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...
Upper level trough moves eastward very slowly through Wednesday
night. A surface trough should linger over/near Lake Erie through at
least Wednesday morning. This may assist with shower/thunderstorm
development through Tuesday afternoon, especially across the
eastern half of the CWA. Models then attempt to move everything
eastward with the upper level trough. Still slightly concerned we
will add some rain chances to Wednesday with later updates as some
jet energy moves across southern Ontario.

Temperatures look to be near seasonal averages through the short
term period.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
A broad surface trough will linger over the area through Friday
night as a surface high pressure gradually shift southeast. On
Friday, a weak cold front associated with a low pressure near the
Gulf of St. Lawrence is forecast to move southeast across. This
boundary will bring a brief chance of precipitation, unless it
stalls across the area. Opted to maintain a front that stalls to the
southeast of the area for now, keeping chance PoPs in the forecast.
There is a non-zero chance of thunder with this system, although it
will be highly dependent on instability developing and any upper
level support present. Late Friday into Saturday, an upper level
ridge, and associated surface high pressure, will build over over
the Eastern U.S. and persist through the remainder of the period. On
Sunday, an increase in southerly winds will mark an increase in high
temperatures, reaching into the mid 80s, which is expected to be the
warmest day for the period. Dewpoints on Saturday and Sunday will
climb into the low to mid 60s, marking a return of humid, muggy
conditions across the area.

&&

.AVIATION /18Z Sunday THROUGH Friday/...
Variable aviation conditions will continue through the afternoon
with pockets of MVFR stratocu with expanding showers and
thunderstorms through the afternoon. Convection has moved back
into NW Ohio and is filling in across Central Ohio. This
activity will expand and move northeast across the local area
through about 02Z. A few of the stronger thunderstorms could be
capable of producing a wind gust to 40-50 knots if the storm
collapses over the terminal. A few funnel clouds have also been
spotted in NW Ohio as storms have exhibited weak rotation.

As showers and thunderstorms diminish tonight, any breaks in the
clouds will tend to result in reduced visibilities or stratus in
the 06-15Z window given the moist airmass in place and broad
cyclonic flow. Have tried to trend terminals towards IFR, mainly
in the 09-13Z window. Can not rule out dense fog if the stratus
does not fill in first. The trough will be over eastern Lake
Erie on Monday and additional showers are expected, especially
over and downwind of Lake Erie. Will need to add these to the
terminals as confidence increases in timing. Winds ahead of the
trough will be southerly at 5-10 knots, shifting to
northwesterly behind the trough. Most areas will see a period of
light and variable winds overnight.

Outlook...Non-VFR possible with scattered rain showers and
thunderstorms Monday through early Tuesday, with the best chance
Saturday afternoon through Monday.

&&

.MARINE...
Low pressure is expected to track eastward near the south shore of
the lake tonight into Monday morning. In the lows wake a cold front
crosses the lake with winds becoming northwest to north. Speeds
generally remain under 15 knots which typically wont build waves
above the 2 to 4 foot range. These northerly winds persist into
Monday night with maybe a slight increase in the speed. A short
small craft advisory may be needed Monday evening into the
overnight. Will definitely need to mention a moderate risk of rip
currents in the HWO for a decent portion of the lake east of the
Islands Monday into Monday night. Will also need to monitor for
waterspouts along the frontal boundary.

A surface trough then lingers on/near the lake into Wednesday. Just
cool enough air aloft and the convergence along the trough axis may
be enough to produce some waterspouts. Confidence not as high with
this potential to mention in the forecast at this time. If
conditions look more favorable over the next couple days we will add
them.
