Area Forecast Discussion
National Weather Service Cleveland OH
315 PM EDT Tue Jul 7 2020

.SYNOPSIS...
High pressure ridging will persist across the lower Great Lakes
through Thursday. An upper trough will move east across Ontario
by the end of the week, dragging a cold front southeast across
the lower Great Lakes by Friday evening into Saturday.

&&

.NEAR TERM /THROUGH WEDNESDAY NIGHT/...
Thunderstorms have initiated across the area and have proven to
carry along high rain rates of up to 2 inches an hour. The
strongest thunderstorms severe wise appear to be located just
south of the area across Coshocton County. Thunderstorms will
continue to slowly propagate southeastwards out of the area over
the next several hours.

Previous Discussion...
Temperatures are quickly rising across the area into the upper
80s to lower 90s with near 70 dew points being advected
northeast into the area from SW OH, SE IN. This will result in
PWATS of 1.8 to 2.0 inches later this afternoon, coincident with
shower and thunderstorm activity. Showers and thunderstorms are
most likely to initiate between noon and 2 PM along the
northeast lakeshore area where a lake breeze and subtle
shortwave will create a convergent zone of lift. The expectation
is for this area of showers and thunderstorms to slowly
propagate southeastwards towards Youngstown and Akron later this
afternoon. Slow cloud layer motions (less than 10 knots), PWATS
near 2.0 inches, and moderate MLCAPE of around 1500 J/kg will
allow for pockets of heavy rain, hinted by the WPC with the
marginal risk of excessive rain. The HREF is indicating that the
highest potential for heavy rain will be in the vicinity of the
Akron/Canton area with 3+ inches of rain possible. Have added
an area of heavy rain to highlight the threat for this
afternoon. Isolated wet microbursts could also be possible with
the strongest storms, though confidence remains lower for this
threat.

Wednesday will feature even weaker steering flow across the area
with a similar, albeit perhaps a little less moist airmass in place
with PWATS around 1.60 inches. Shower and thunderstorm activity on
Thursday appears to be less scattered than today, though storms
would once again pose a threat for heavy rain and a stronger,
isolated downburst. Storms appear to initiate along a lake breeze
boundary at a similar time to today, around 1 to 2 PM. Highs on
Wednesday will be a degree or two higher than today with heat
indices inching closer to the 100 mark though not anticipating a
heat advisory at this time.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
A progressive upper level trough will move east across the
northeastern United States during this forecast period. The upper
level trough will slow in forward motion as it reaches the East
Coast Friday night.  This will keep the local area in upper level
troughiness by the end of the period. Surface low pressure will move
into central Ontario, Canada by Thursday night forcing a cold front
east across the local area Friday. The front will tap into moisture
from the southeastern United States and Atlantic coast.  The bulk of
the moisture will be over the western half of the forecast area
Friday morning and then shift east during the afternoon.  The front
should be over the eastern half of the forecast area by Friday
night. Best chance for showers and thunderstorms will occur over the
western half of the area with the front with a chance well ahead of
the front in the eastern half of the area. The cold front will
eventually move into the western portions of Pennsylvania by late
Friday night. Air ahead of the front is expected to be on the warm
side with warm air advection and highs in the lower 90s and lows in
the 70s.  After frontal passage, lows Friday night will drop into
the upper 60s to lower 70s.  Dewpoints will be increasing to the
lower 70s pre-frontal air mass. Potential exists for destabilization
and threat for strong thunderstorms Friday.  So, will have to
monitor as we get closer.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
Broad upper level troughiness will begin to give way to an upper
level ridge that is expected to build east toward the western Great
Lakes by Monday night.  The ridge will push the upper level trough
east of the area and dominate the local region by Tuesday.  A
surface cold front will just east of the local area will continue to
move east of the region Saturday.  A post frontal trough will follow
the front and weaken by Sunday morning.  A swath of moisture
associated with the upper level trough and the reflected trough at
the surface will advance east over the area Sunday.  This feature
will keep a threat for showers and thunderstorms Saturday into
Monday and then shifting east of the area by Tuesday as high
pressure ridge at the surface builds into the area.  Slight cold air
advection will take place during this period under the upper level
trough.  Temperatures will drop back into the 80s for highs and lows
in the 60s.

&&

.AVIATION /18Z Tuesday THROUGH Sunday/...
VFR conditions across the TAF sites this afternoon, though pockets
of MVFR and even IFR visbys will be possible associated with heavier
showers and thunderstorms which have just begun to initiate. The
most likely candidates for MVFR and IFR conditions appears to be at
MFD/CAK/YNG as convection will slowly sag southeastwards throughout
the afternoon into the early evening hours. Some isolated shower and
thunderstorm activity could make its way into the vicinity of FDY,
but have not added any prevailing or tempo groups at this time.

Otherwise, winds will be light and variable and generally under 10
knots with exception of higher winds and gusts in thunderstorms.

Outlook...Non-VFR possible with scattered showers and
thunderstorms Wednesday and Thursday afternoon. Higher coverage
of showers and thunderstorms is expected late Friday into
Saturday as a front crosses the area.

&&

.MARINE...
Quite variable winds 10 knots or less expected through this forecast
period.  Expecting waves to be 2 feet or less during the period as
well.  No wind headlines expected on the lake in the next 5 days
other than threats for strong thunderstorms by Friday.
