Area Forecast Discussion
National Weather Service Cleveland OH
404 PM EDT Mon Jun 14 2021

.SYNOPSIS...
A trough will linger over the Northeast through Tuesday and a
cold front will push south across the area on Tuesday
afternoon. High pressure will build over the Great Lakes and
Ohio Valley from the northwest Wednesday and Thursday, before a
cold front approaches from the west on Friday and moves east
across the area Saturday.

&&

.NEAR TERM /THROUGH TUESDAY NIGHT/...
The majority of the near term period will be dominated by a
deep trough over the northeastern US that will usher a series of
shortwaves over the area through Tuesday. This may produce a
few rounds of isolated showers and maybe an isolated
thunderstorm across the northern portion of our CWA through
tonight, but instability is very limited and dry air is already
beginning to filter into the area from the northwest. Didn't go
more than low-end slight chance PoPs at this time, but will
continue to monitor the showers moving south across Lake Erie
from southern Ontario. Overnight lows will fall into the mid to
upper 50s.

A reinforcing cold front will push south across the area on
Tuesday afternoon, which could produce isolated showers and
perhaps a few rumbles of thunder south of the lakeshore during
the late morning and early afternoon hours. Instability will be
limited, so have low-end slight chance (20%) PoPs for the time
being. High pressure will begin to build over the area from the
northwest Tuesday evening, which will usher cooler, drier air
into the Great Lakes region Tuesday night. Highs will be in the
low to mid 70s across the majority of the area Tuesday,
although a few spots in NW OH may climb into the upper 70s. Lows
will be in the much cooler upper 40s to lower 50s, with upper
50s possible along the immediate lakeshore.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
Quiet and less humid weather will arrive through the short term
period with seasonably cool high temperatures in the 70s and
perhaps upper 60s on Wednesday as persistent northerly flow
exists aloft and anomalously cool 850 mb air filters south
across the region. Chilly lows will be found across the area
Wednesday night in the 40s to lower 50s.

Mostly sunny skies should persist on both Wednesday and Thursday.
Thursday will be exhibit highs closer to normal in the 70s and lower
80s as northerly flow aloft loosens and becomes more northwest
oriented.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
Activity begins to ramp up across the region in the long term period
as a positively tilted upper trough wobbles south into the Upper
Midwest by Friday and as increased low-level moisture returns
northwards through the Ohio Valley. Ahead of the trough, a cold
front will extend southwest through the Great Lakes and is
anticipated to reach the vicinity of NW OH by Friday evening. Early
signs point to scattered thunderstorm chances Friday afternoon
through the overnight along and ahead of the cold front. Some storms
could reach severe levels with effective shear values around 40
knots, perpendicular to the approaching front.

By Saturday, models differ on the timing of the cold front, though
forward motion should slow. The most likely solution is for the
front to sag ever-so-slightly south and east of the region, which
would limit any thunderstorm chances. Weak high pressure will settle
in behind the front Saturday afternoon/evening and could persist
through Sunday as the cold front becomes stationary in the vicinity
of central OH. By Monday, another upper trough will dig south across
the Upper Midwest, and should pull this stationary front northwards
as a warm front. Thus, thunderstorms could once again be possible on
Monday.

Humid weather with temperatures in the 80s will return on Friday
associated with the warm and moist Gulf of Mexico return flow.
Behind the cold front, more seasonable and less humid weather in the
70s could be more common. By Monday, more humid weather with
temperatures in the 80s should arrive once again.

&&

.AVIATION /18Z Monday THROUGH Saturday/...
VFR conditions are expected at most terminals for the majority
of the TAF period. A few showers are present several miles south
of KYNG early this afternoon, but the activity should not
backbuild into the vicinity of the terminal. Can't rule out
scattered showers developing near KTOL this afternoon/early this
evening and KERI overnight as impulses traverse across the
area, so have VCSH mention at both terminals for a few hours.
Also have a brief period of MVFR cigs at KERI during the
overnight hours due to residual low-level moisture. Winds will
be variable to 12 knots with gusts to 20 knots through this
afternoon, before becoming northerly to northwesterly and
decreasing below 10 knots this evening. Northwesterly winds will
increase to 10 to 12 knots with gusts to 20 knots on Tuesday
afternoon.

Outlook...Non-VFR possible in showers/thunderstorms Friday and
Saturday.

&&

.MARINE...
Northerly flow around 15 knots will persist tonight which could
lead to some 3 to 4 footers across the central and eastern
basins of the lake. By Tuesday, a stronger cold front will move
south across the lake, ushering in northerly winds of near 20
knots by late Tuesday afternoon and evening. The enhanced
onshore flow will likely result in a Small Craft Advisory for
the central and eastern basins of the lake during this timeframe
and into Wednesday morning. High pressure will build south
across the lakes Wednesday into Thursday, with generally weak
flow anticipated. By Friday, south to southwesterly winds
increase to around 15 to 20 knots, though given the offshore
nature of the flow, not anticipating any headlines at this
point.
