Area Forecast Discussion
National Weather Service Cleveland OH
237 PM EDT Wed Jun 18 2025

.SYNOPSIS...
A cold front will move across the region this evening and
overnight. A strong upper level ridge of high pressure will
build over the Ohio Valley this weekend into early next week
and bring a Heat Wave across the region.

&&

.NEAR TERM /THROUGH THURSDAY/...
2:30 PM Update:

Key Messages:
-Scattered showers and thunderstorms are ongoing over Northeast
 OH and Northwest PA this afternoon. These storms are capable of
 producing locally heavy rain, with a lower risk for isolated
 severe weather.
-After a break through the remainder of the afternoon, an arcing
 line of storms is expected to quickly push in from the west-
 southwest this evening with greater potential for severe
 weather.
-The greatest confidence in severe weather this evening in
 across Northwest OH, where an Enhanced Risk (risk level 3/5)
 for severe weather is in place. The risk gradually diminishes
 east across North Central and Northeast OH, where a Slight Risk
 (level 2/5) is in place to near the PA border. The risk level
 drops off to Marginal (1/5) across Northwest PA.
-The main severe risk this evening will be damaging wind gusts,
 with large hail a secondary risk. There is a lower but non-
 zero potential for tornadoes, especially across Northwest OH.
-Timing into Northwest OH (including Toledo/Findlay) for the
 severe threat is greatest 6-9 PM...across North Central OH
 (including Sandusky, Mansfield, and Lorain) 7-10 PM...in the
 Cleveland-Akron-Canton corridor 8-11 PM...in far Northeast OH
 (including Youngstown) 9 PM-12 AM...and in Northwest PA between
 11 PM-2 AM if storms remain strong that far east.

An MCV over Lake Erie is helping to force a batch of scattered
showers and thunderstorms from the lake into northern OH and
northwestern PA early this afternoon. The environment is most
supportive of heavy rain with this initial round, given skinny
instability profiles, high precipitable water values, and rather
marginal amounts of wind shear. With that said, a couple of
cells have been weakly rotating, so will continue to monitor for
isolated/marginal severe potential with the current activity. A
lull in activity is expected behind this activity for a few
hours into this evening, with warm, humid, and somewhat breezy
conditions. Hopefully everyone enjoys 70-75F dew points...

After the brief break, the main focus for severe weather arrives
from the west this evening. Radar/satellite/water vapor depict
an arcing and strongly-forced band of convection evolving near
the IL/IN border, with plenty of heating taking place ahead of
the line. The strong forcing and continued destabilization
should allow this line to surge into Northwest OH at a strong to
severe intensity this evening. The greatest forcing will pass
just northwest of the region, and timing gradually becomes an
issue farther east as we move towards and past sunset. So, the
greatest and highest-confidence severe threat is across
Northwest OH (in and near the SPC enhanced risk), with the
threat gradually lowering to the east. However, suspect the line
of storms will have enough momentum to remain strong to at
least locally severe to at least the I-77 corridor (even if
they're gradually weakening by then), with a lower-confidence
severe threat across the rest of Northeast OH and perhaps into
Northwest PA. There's certainly a chance hit-or-miss severe
weather occurs all the way east across our forecast area this
evening into tonight, though will need to assess the state of
the incoming storms this evening and environment across the
local area behind this afternoon's storms to say with more
confidence how far east an organized severe threat will persist
this evening. With that said, there are enough "pros" that the
SPC did expand the Slight Risk east to the OH/PA border with
their 12:30 PM convective outlook update. Activity should exit
OH by midnight, if not slightly earlier, with activity exiting
PA around or just after midnight (see timing in Key Messages).

In terms of potential severe hazards this evening, the
combination of moderate instability (1500-2500 J/KG of MLCAPE),
steep low-level lapse rates (0-3km lapse rates of 8-8.5C/km),
marginal to moderate downdraft CAPE of 700-900 J/KG, and
marginal to moderate shear (effective bulk shear 30-35kt and
0-3km shear of 20-30kt with modest SRH) across Northwest OH will
support primarily a damaging wind gust risk with a linear storm
mode. If there are any discrete cells, marginally severe hail
is possible...though the primarily linear mode and poor mid-
level lapse rates (near 6C/km) should limit large hail
potential. Shear is marginal for a tornado threat, though we
will need to watch for any bowing/surging portions of the line
or any rotating discrete cells that get ingested by the line
for a localized tornado risk. As storms push east this evening,
shear will remain similar to the values listed above or may
increase slightly...while instability and low-level lapse rates
gradually weaken farther east as we move past sunset. This will
likely maintain a primarily wind damage risk with surging/bowing
portions of the line farther east across our area...with lower
but non-zero hail and tornado potential. Will also need to
monitor for locally heavy rainfall and flooding with high
precipitable water values remaining in place and some recent
heavy rainfall, though increased flow aloft should keep storms
generally moving this evening and into tonight.

A general lull in activity is expected overnight tonight behind
the round of storms, though with the surface cold front trailing
behind the line of storms there could be some lingering shower
potential overnight tonight. Lows will generally dip into the
mid to upper 60s, with somewhat brisk southwest winds continuing
tonight (gusts potentially 25-35 MPH) as low pressure lifts into
the Great Lakes. The axis of the mid and level trough will
swing through our region on Thursday. We will continue with the
chance for scattered rain showers and maybe some isolated
thunder during the day Thursday with the higher POPs favoring
the morning and midday. Rain chances will quickly taper off from
west to east during the afternoon as the weather system pulls
away. Considerable cloudiness and push of a slightly cooler,
less humid airmass will follow the cold front passage on
Thursday with high temps in the mid to upper 70s.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/...
Broad upper level trough will continue to exit to the east
Thursday night as a ridge aloft and at the surface builds into
the region from the west. Thursday night will be the mildest
night of the short term as lows settle in the upper 50s to lower
60s in the wake of the upper trough and surface cold front.
High pressure remains nestled south of the local forecast area
this weekend and will allow for warm, moist air to advect from
the Gulf. Highs on Friday will rise into the upper 70s to lower
80s with lows in the mid to upper 60s. Heat becomes established
by Saturday as highs rise into the mid 80s to low 90s with
little overnight relief as lows settle in the upper 60s to mid
70s Saturday night.

&&

.LONG TERM /SUNDAY THROUGH TUESDAY/...
Hot and humid weather is expected to last through the long term
period with potentially record breaking heat by early next week.
High temperatures are forecasted to rise into the 90s Sunday through
Tuesday coupled with dew points in the upper 60s to lower 70s.
Little overnight relief is expected as overnight lows settle in the
mid 70s each night. Maximum heat index values through the long term
will range between the upper 90s to 100F with Heat Advisories
possibly needed through early next week. Next best chance for
afternoon showers and thunderstorms will be on Tuesday as a
shortwave moves overhead.

&&

.AVIATION /18Z Wednesday THROUGH Monday/...
Scattered showers and thunderstorms are ongoing from
approximately LPR to MFD points east, with the greatest coverage
over and near Lake Erie. This activity will continue east while
exiting through late afternoon. Lightning, along with brief vsby
reductions to IFR or lower, can accompany storms within this
activity. After a brief lull with breezy south-southwest winds
and mainly VFR conditions, an arcing line of thunderstorms is
expected to surge in from the west this evening. Confidence in
impacts is very high (>80%) at TOL, FDY, and MFD, high (60-90%)
at CLE and CAK, and medium (40-60%) at ERI and YNG. Included
TEMPOs at all sites to indicate potential wind gusts, vsby
reduction, and a best guess at a 1-2 hour timing window of
potential direct impacts. This activity exits east, though a
cold front moves through from west to east late tonight into
early Thursday. This will bring continued potential for shower
activity along the front, with MVFR ceilings likely spreading in
along and behind the cold front into Thursday. Another round of
showers and some thunder is likely Thursday afternoon, though
future cycles will take a better look at that.

South-southwest winds at 7-15kt with a few gusts to 25kt will
continue through this afternoon and early evening. Winds
gradually shift more southwesterly tonight and likely increase a
bit to the 10-18kt range with gusts 20-30kt into Thursday.

Outlook...Non-VFR likely with scattered showers and isolated
storms Thursday afternoon. A large high pressure system will
build over the region over the weekend into early next week with
fair skies and quiet weather.

&&

.MARINE...
Southerly winds generally around 10 knots will continue through this
evening before increasing to 15-20 knots and shifting to the
southwest tonight. Elevated southwesterly to westerly winds 15-20
knots will continue through Thursday morning. Highest wave heights
building to 3-5 feet should remain limited to open waters through
Thursday morning given the offshore component.  Opted to hold off on
any small craft advisories with this forecast package and wait
another forecast cycle to better determine magnitude and timeframe
of elevated wind speeds.

Westerly winds will diminish to 5-10 knots through Thursday as high
pressure builds across the region through the end of this week. A
warm front will lift north across the lake on Saturday which will
increase southwesterly winds to 10-15 knots before they diminish to
5-10 knots on Sunday as high pressure persists.
