Area Forecast Discussion

.SYNOPSIS...
A warm front will move through the area this evening before a
cold front approaches from the west tonight into Thursday. This
front will settle near the Ohio River for Thursday into Friday
before a low pressure system forms and lifts this feature north
as a warm front Friday night.

&&

.NEAR TERM /THROUGH THURSDAY NIGHT/...
7:45 PM Update...
There are a multitude of things we are keeping an eye on. In the
observations, we are watching the progress of the warm front,
which has moved into the southwest part of our forecast area.
There is a sharp T/Td gradient across this from with around
75/60 T/Td behind the front. As the warm front lifts
northeastward, should see a sharp increase in temperature and
dew point (which will contribute to an increase in instability
tonight.

Convection has already been ongoing for a few hours to our west
and southwest, especially in IN/IL and points to their south.
This may seem far away but strong wind flow is resulting in very
fast storm motions. Latest model guidance projects convection
impacting the I-75 corridor as early as 02Z. Severe weather
remains possible with damaging winds and a few tornadoes being
the primary weather hazards of concern. Wet conditions and high
rainfall rates should lead to at least minor flooding for a good
portion of the area, but the greater flash flooding risk
continues to trend a bit lower (still possible especially in
Northwest Ohio but should remain isolated), due to relatively
fast storm motions and gradually decreasing rainfall rates
through the overnight hours.

Previous Discussion...
The first round of showers and thunderstorms has exited stage
right this afternoon after a round of rain spanning 0.50-1.50",
some nuisance flooding, and some small and isolated large hail.
The main warm front to help trigger these storms is into central
Ohio and will continue to extend north across the forecast area
this evening. The advancement of this warm front will be key to
the severe weather threat across the area tonight. Temperatures
in Mount Vernon have crossed the 70 degree mark and Marion has
exceeded 60 degrees, but the gradient is tight with Findlay
still below 50 degrees and closer to the 40s near Lake Erie. The
front should advance to near Lake Erie by 8-9 PM and the western
two-thirds of the forecast area should reach at least 60 degrees
and some instability should build with 1000-1500 J/kg of SBCAPE,
where 70s could still be achieved. This will be plenty of
instability to work with, as a strongly sheared air mass
continues to develop across the Ohio Valley with a 70 kt low
level jet at 850 mb entering tonight and mean 0-3 SRH values
exceeding 400 m2/s2. A line of convective development continues
to blossom across Illinois and Missouri and it will continue to
expand north and east with time this afternoon. This will
organize and be the main show that will enter a favorable
atmosphere for severe weather. Therefore, the Enhanced Risk
remains for the western forecast area with the Slight Risk
expanding to the east from there. All severe weather hazards
remain on the table with a few tornadoes embedded within a line
of convection, damaging wind gusts, including some significant
severe over 65 kts, and large hail. The timing will be into
Northwest Ohio around 8 PM and extending east through the night
around I-71 by Midnight and into the overnight. The trend in the
forecast is that these storms are more likely to move through
faster than previously anticipated and the flash flood threat
may be more conditional and slightly lessened. However, will
keep the flood watch with the overall wet pattern through the
weekend and will monitor for hydrological hazards tonight.

The cold front will be into the area Thursday morning and will
move southeast. The bulk of the storms will be southeast of the
area during the daytime hours and the Day 2 Severe Risk has been
removed from the area with the forecast trending dry. Highs in
the 60s may be achieved early in the day. The front will be to
the south of the forecast area on Thursday night but will be a
focus area for new rain development that may push north through
the night. Some efficient rainfall should enter the southern
forecast area and there could be some conditional flooding for
Central Ohio, as highlighted by a Day 2 Slight Risk of Excessive
Rainfall.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
Friday will be a lull to the active weather for most of Northern
Ohio and Northwestern Pennsylvania as the boundary stalls out to the
south in Southern Ohio. There maybe some scattered precipitation
throughout the day in Central Ohio, through most will stay dry. A
surface low and boundary will start to move northeastward from the
lower Mississippi Valley as a strong LLJ moves into the region. This
will bring back ample moisture from the south back into Northern
Ohio. Heavy rainfall will return to the region with the strong
moisture advection for starting late Friday night and early Saturday
morning. In turn, most of the CWA will continue to be in a MRGL risk
for excessive rainfall on Friday and a SLGT risk on Saturday. There
will be a flash flood and river flooding threat across much of the
region, with the highest probability across areas west of Interstate
71. Total rainfall forecast for Friday through Saturday night will
be from 2-4" across the region. There does lie a small, isolated
risk for severe weather across the far southwestern counties of the
CWA which warranted a MRGL risk from SPC, though it will be largely
overshadowed by the heavy rain threat. The best opportunity for any
sort of severe weather will be during the afternoon timeframe on
Saturday as temperatures start to climb with the southerly flow. An
approaching cold front from the northwest will start to push
everything out to the east late Saturday night.

Temperatures on Friday will fall a bit from earlier in the week as
we will be on the northern side of the boundary with highs in the
50s across the region. On Saturday, temperatures will rebound with
the southerly flow and high will reach into the mid to upper 60s.
Parts of Northwest Ohio may not hit the 60s as the approaching cold
front could keep the high temperatures down some.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
The aforementioned cold front from the short term will be entering
the region from the northwest driven by a much larger upper level
trough that will be digging down into the Great Lakes region Sunday
night into Monday. A couple weaker low pressure systems and
associated cold fronts will move through the region with the upper
level trough through the beginning of the week. The initial cold
front on Sunday will drive out most of the precipitation in the
region throughout the day. There may be some lingering showers on
the back end in Eastern Ohio and Northwestern Pennsylvania. A
secondary, weak low pressure system will move into the region on
Monday with a more widespread, though low probability, chance for
precipitation across the region. The northerly flow behind the
system and with a high pressure building to the west, will bring
down much colder air leading to the opportunity for a rain/snow mix
during the morning and overnight hours Monday and Tuesday. Rain/snow
showers will persist in the snowbelt through Tuesday night as the
high builds eastward across the region. Temperatures will be below
average to start next week with the the cold air advection.

.AVIATION /00Z Thursday THROUGH Monday/...
VFR conditions are observed areawide at around 00Z, with
midlevel clouds. South to southeast winds generally in the
20-25 knot range this evening and overnight except in Erie
County where gusts to 40 knots will be possible.

A line of thunderstorms will move west to east across the area,
generally consisting of ceilings around 2-5kft, visibilities in
the 2-6SM range, and the potential for gusts in the 35-50 knot
range, especially for the western part of the forecast area
where confidence is higher in stronger thunderstorms. General
tendency should be for thunderstorms to weaken in intensity as
they move east across the area overnight tonight. The cold
front will move through the area late in the TAF period with
rain coverage decreasing and winds veering while remaining with
elevated gusts. MVFR ceilings should still remain for a couple
hours after the bulk of the thunderstorms exit late tonight into
Thursday morning but should quickly improve to VFR conditions by
mid to late morning. West winds will gust to around 20-25 knots
behind the cold frontal passage before diminishing close to
sunset.

Outlook...Non-VFR ceilings may continue across the region
Thursday night into Friday with some non-VFR visibility possible
in showers and storms south. Non-VFR more likely areawide in
showers and thunderstorms Friday night into Saturday. Non-VFR
ceilings are expected to continue into Sunday.

&&

.MARINE...
A Small Craft Advisory is still active for the entirety of the
nearshore zones through Thursday morning when the western half will
fall off and Thursday night for the eastern half. Winds will be
predominantly out of the south this evening at 15 to 25 before
increasing to 20 to 30 knots ahead of an approaching cold front.
Behind the cold front, winds will shift out of the west and subside
to 10 to 15 knots throughout the day on Thursday. Winds will
continue to decrease into the overnight hours and Friday morning and
veer to out of the north at 5 to 10 knots. Winds will stay light
through Friday before increasing Saturday morning to 10 to 15 knots.
There will be another shift in the winds Sunday morning with a
passing cold front bringing the winds out of the north at 10 to 15
knots which will continue through Monday.
