Area Forecast Discussion
National Weather Service Cleveland OH
Issued by National Weather Service BUFFALO NY
115 PM EDT Wed Apr 18 2018

.SYNOPSIS...
Low pressure will move across Central Ohio tonight, then to the
New England coast on Thursday. This will bring rain to northern
Ohio and northwest Pennsylvania later today which will mix with
and change to snow showers tonight before tapering off
Thursday. A large area of high pressure will build southeast out
of Canada reaching the Great Lakes region to end the week.

&&

.NEAR TERM /THROUGH THURSDAY/...
A narrow wedge of surface high pressure remains over Ohio and
western PA near midday. Radar is clear with satellite showing
lingering stratus over Lake Erie, northeast OH and northwest PA.
Skies are clear to partly cloudy south of a Toledo to Akron
line. Weak southerly low level winds will continue to eroding
the stratus from the south leaving most areas with a few hours
of sun before clouds increase this afternoon evening ahead of a
warm front. This front will lift north into Ohio ahead of low
pressure approaching from the mid-Mississippi River Valley.
Clouds will thicken through the afternoon. Dry low level air
will delay the onset of precip until this evening. We have
slowed down the arrival of rain a few hours based on 12z meso
models/ensembles. Rain will expand from west to east across Ohio
between 4 and 9 PM.

By tonight, low pressure will reach Central Ohio then quickly shift
east as a compact upper level wave approaching from the west merges
with energy moving around the back side of the east coast trough.
Precip type will remain rain through the evening before cold air
wrapping into the back side of the system allows for a transition to
snow. Expecting fairly good precip rates given the dynamic system
aloft which should allow for a complete transition to snow and even
some light accumulations. Snowfall totals range from less than an
inch in NW Ohio to around 2 inches in portions of the snowbelt with
locally higher amounts in NW PA. Counties closer to Central Ohio
may only receive trace amounts of snow. Deeper moisture pulls
away quickly on Thursday but expect to see snow showers linger
in the snowbelt through at least the morning and into the
afternoon for inland NW PA.

Temperatures today will range from the lower 40s near the lakeshore
to around 50 in many of the southern counties. Thursday will be
cooler downwind of Lake Erie with NE Ohio and NW PA in the 35-40
degree range while NW Ohio reaches the mid 40s with skies
clearing in the afternoon. Seasonal norms are near 60 degrees.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/...
A relatively quiet period weather-wise is shaping up for the end of
the week into the weekend, as a broad upper trough over the eastern
Great Lakes moves east away from the region and high pressure slowly
builds into the region from the west. Some lingering lake effect
snow showers are possible Thursday night into Friday morning, mainly
across NW PA, until moisture becomes limited as 850mb temps begin to
warm. Otherwise, dry conditions are expected across the forecast
area through Saturday night. Below normal temperatures are expected
through the period, with little air mass moderation expected as
the surface ridge becomes centered over the central Great Lakes
and north/northeast flow curtails any appreciable WAA. Lows
will range from the mid 20s to low 30s Thursday night into the
low to mid 30s by Saturday night. Highs on Friday will range
from the upper 30s across northwest PA to around 50 degrees
across northwest Ohio. Highs on Saturday may be a few degrees
warmer, ranging from the mid 40s to low 50s.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
Models are finally hinting at a warm up in the extended, as broad
ridging over the Great Lakes Sunday moves east into New England by
Monday night. A cutoff upper low will track east from the lower
MO valley into the southeast US Sunday through Tuesday, but
should stay far enough south to bring little more than clouds to
the area through the long term period. WAA will begin to ramp
up into the region as the low moves into the southeast US and
the ridge axis moves east of the Great Lakes, with some
moderating temps approaching normal values Monday, and possibly
a few degrees above normal in some areas by Tuesday. Models are
showing a positively tilted upper trough digging into the Great
Lakes by midweek, with a surface cold front pushing into the
area, and surface cyclogenesis occurring across the region. This
will increase precip chances across the region, but should hold
off until Tuesday night into Wednesday at this point. Highs on
Sunday in the low to upper 50s will warm into the mid/upper 60s
inland (upper 50s/low 60s near Lake Erie) by Tuesday.

&&

.AVIATION /18Z Wednesday THROUGH Monday/...
The stratus shield is continuing to slowly erode from the south
as diurnal mixing along its periphery is entraining drier air
into the lower levels. This should allow for a few hours of VFR
conditions at all sites before the next system approaches from
the west.

MVFR skies will again overspread the area from W-E late this
afternoon/evening as the next system approaches. Most sites will
start as rain with easterly flow increasing as the precipitation
develops. The exception seems likely to be KERI as colder air
feeding from the NE may keep all things snow. That said, as
colder air moves into the area on flow that turns from NE to N
late this evening and overnight, all sites will rapidly
transition to snow with cigs dropping like a rock to IFR as
precipitation becomes more persistent.

Once the system pulls east on Thursday, gusts NNW will prevail
at all sites with lake effect snow showers common.

OUTLOOK...Non-VFR possible again late Wednesday night and
Thursday, lingering in NE Ohio and NW PA into Friday.

&&

.MARINE...
High pressure will briefly work east across the lake today,
with winds becoming light and variable through the afternoon.
Low pressure tracking east just north of the Ohio river valley
today and tonight with bring increasing northeast winds tonight,
becoming northerly in the 15-25 kt range by Thursday morning. A
small craft advisory will again be needed Thursday. Winds will
slowly back northwest through Thursday afternoon and will become
10-20 kts Thursday night, subsiding to 15 kts or less through
the day on Friday as high pressure begins to build across the
lake. Winds will become light and variable Friday night through
the weekend with high pressure overhead, becoming predominantly
easterly Sunday night into Monday as the ridge moves east of the
Great Lakes.
