Area Forecast Discussion
National Weather Service Cleveland OH
331 AM EDT Fri May 16 2025

.SYNOPSIS...
A warm front will continue to lift north of the area this morning as
a low pressure system over the north-central U.S. meanders east.
This low will move a cold front east today, before stalling across
central Ohio by mid-afternoon. This will lift north again as a warm
front tonight before a cold front and the associated low push east
on Saturday. High pressure will return on Sunday through early
Tuesday.

&&

.NEAR TERM /THROUGH SATURDAY/...
A deepening upper level trough with a nearly vertically stacked low
pressure is expected to meander east throughout the near term
period, allowing for multiple chances of precipitation. Currently,
this low pressure is extending a warm front across portion of Lake
Erie, with the far eastern edge sagging south across far NE OH. This
boundary will continue to lift north this morning as a weak cold
front/shortwave trough pushes east into late morning. Overall
forcing with the boundaries themselves is weak, however the
atmosphere is still primed for the potential of severe weather, with
the caveat being any storm would have to break the strong CAP to
develop. Mesoanalysis suggests 1500-2000 J/kg of SBCAPE across the
area with DCAPE values of 1000-1200 J/kg. In addition, an area of
deep moisture convergence remains present over far NE OH and NW PA.
With all that being said, there remains a non-zero chance of
isolated severe weather across far NE OH and NW PA over the next
couple hours. Primary concern will remain gusty winds, although
small hail cannot be ruled out.

By late morning, the aforementioned weak cold front will settle just
south of the area, allowing for skies to become mostly sunny. Clear
skies mixed with WAA will allow temperatures to climb into the low
to mid 80s, possible feeling a tad warmer with dewpoints lingering
in the upper 50s to low 60s. The stalled boundary will again lift
north as another warm front this evening, followed by a stronger
cold front late tonight into Saturday morning. These frontal
passages will have better overall synoptic support with them as the
center of the low moves across the northern Great Lakes. With
clearing skies and a moist environment, decent destabilization is
expected this afternoon with hi-res models suggesting 2000-3000 J/kg
of MUCAPE and around 50-55 knots of bulk shear. Even with the
atmosphere being primed with basic ingredients for convection, there
remains a bit of uncertainty on how far north the airmass will
destabilize to that extent and in regards to how much CIN will
develop with the transition to a less diurnally favorable timing,
similar to what happened this past night. Taking into account all
the variables, SPC has highlighted much of the area in a Day 1
Slight Risk, with the exception of far NE OH and NW PA which remain
in a Marginal Risk. Primary concern will be strong, damaging winds
but isolated large hail and a tornado or two cannot be ruled out.
This severe potential will be highly dependent on how the atmosphere
changes over the next several hours. In addition, heavy rainfall
associated with strong thunderstorms will pose a local flood risk,
especially in poor drainage or low lying areas and as a result WPC
has issued a Day 1 ERO for the entire area. Please stay weather
aware today and have ways to receive warnings at night as this may
turn into an overnight event. Temperatures tonight will drop into
the low to mid 60s.

On Saturday, showers should gradually diminish from west to east as
the cold front push east and a surface trough lingers over the area.
Enough wrap around moisture associated with the low in southern
Ontario/Quebec will allow for rain showers to persist across the
eastern portion of the CWA through Saturday, before drying out
Saturday night. Much cooler temperatures arrive on Saturday behind
the departing front, with highs only climbing into the low to mid
60s. In addition, gusty winds of 20-25 mph have the potential for
temperatures to feel a bit cooler than that.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
Upper level low continues its exit to the east with a few
lingering cold air advection showers over the far northeastern
zones aided by weak surface and upper level troughs. POPs gone
by 00Z Sunday, but the general troughing over the southern Great
Lakes will persist through Sunday with some degree of cloud
cover with low level moisture that is still refusing to
relinquish its grip on the region. This period of northerly
surface winds, 500mb heights and 850mb temperatures slow to
recover, and varying cloud cover will support a cooler stretch
of weather that will push into the long term period with
temperatures that will be around 10 degrees below normal. Low
end POPs return late Monday with the approach of a warm front
from the southwest for the southwestern zones of the CWA.

&&

.LONG TERM /TUESDAY THROUGH THURSDAY/...
Upper level ridging has built in across the eastern portion of CONUS
bringing mild and dry weather to the start of the long term period.
The next upper level trough will be developing across the Rockies
late Monday into Tuesday and will bring unsettled weather during the
middle of the week. The accompanying surface low will be entering
the region by Wednesday moving eastward across the Mississippi
Valley into the Ohio Valley. There may be sufficient CAPE and
instability come Wednesday evening into Thursday morning where a few
thunderstorms could be possible across the region. As the surface
low slowly departs out to the east, precipitation will be slow to
depart as well and should expect periodic showers with the wrap
around moisture to occur through the end of the period. Temperatures
for next week are trending to be slightly below average with highs
in the mid to low 60s and lows in the upper 40s.

&&

.AVIATION /06Z Friday THROUGH Tuesday/...
Predominately VFR conditions should persist through much of this
TAF period as the entire area lingers in the warm sector of a
low pressure centered over the north central US. Initial
thoughts earlier this evening were that a MCS was going to surge
east across the area, however all of the convection has remained
north of the area across Michigan. As a result, there was a
large shift in the TAF forecast with limited gusts and
thunderstorms now expected. Opted to maintain a TEMPO for heavy
rainfall and a few rumbles of thunder over the next couple
hours, however this may be a stretch given the strengthening CAP
over the area.

By Friday daybreak, any lingering showers and thunderstorms
will push east of the area allowing for clearing skies and winds
10-12 knots from the southwest throughout today. Tonight,
another round of convection is possible between the 00-06Z
Saturday time frame, although confidence remains low given the
poor handling of ongoing convection in recent model guidance.
Opted to handle this potential with PROB30. There may be a brief
period of non-VFR conditions, but will need to monitor model
trends in the coming hours. Winds gusts will ramp up near the
end of this TAF period as a cold front approaches from the west
and strengthens the gradient across the area.

Outlook...Periodic showers and thunderstorms with non-VFR are
possible through Saturday.

&&

.MARINE...
West to southwesterly flow at 10-15 knots is expected across the
lake for the majority of the day Friday before the winds start to
back overnight to be predominantly out of the south. Waves between 1-
3 feet are expected during through Saturday morning. During the day
Saturday, the winds will veer becoming westerly and increasing to 15-
20 knots across the lake with as a low pressure system moves across
the Northern Great Lakes into Eastern Canada. Waves will build to 4-
8 feet throughout the day into Sunday before subsiding in the late
evening. A Small Craft Advisory will likely be needed for most of
the day Saturday through Sunday afternoon for primarily points east
of the Islands.

As the low pressure pushes off eastward, winds and waves will begin
to subside and become west to northwesterly at 10-15 knots and waves
1-3 feet. Winds will becoming primarily northerly Monday morning as
high pressure and ridging builds over the region and then veer to be
northeasterly through Tuesday. Waves will be less than 3 feet during
this time period.
