Area Forecast Discussion
National Weather Service Cleveland OH
202 AM EDT Thu Apr 22 2021

.SYNOPSIS...
A trough will linger across the region through tonight. High
pressure will build from the southwest on Thursday and move
through the Ohio Valley through Friday. Low pressure will
develop over the southern United States on Saturday and move
northeast into the region for the weekend.

&&

.NEAR TERM /THROUGH TODAY/...
Heavy band of lake effect snow has developed from NW of
Cleveland to Brooklyn Heights to Bedford and Mantua. We are
seeing a quick accumulation on area roadways with visibilities
of 1/4 mile. Some areas could see 1 to 2 inches of snow through
1 AM where the snow band is training. Strong low level
convergence is focused over Lake Erie but this band is expected
to break off from the lake and move southeast through 2 AM as
the trough moves through.

Previous Discussion...
Snow showers over Indiana this afternoon will attempt to push
east into the forecast area. This area of snow is being
supported by the mid-level trough axis and associated vorticity
maximum moving through the region. Snow also has some intensity,
as it taps into some low level instability generated from
breaks in the clouds ahead of this region. Will have chance PoPs
for this afternoon and evening, timed with this feature. Snow
will then transition to being focused to the lee of Lake Erie
with moisture and instability from the lake. However, a
marginally cold low level air mass and some directional shear
will prohibit anything organized in terms of lake effect but
some light snow is possible tonight and have maintained some low
PoPs. Temperatures will be cold tonight with the anomalously
cold air mass and breaks in the clouds to allow for temperatures
to plummet into the 20s. A Freeze Warning has been issued for
our counties where the growing season has begun. High pressure
will build in from the south on Thursday and drier will enter,
ending any precipitation across the region. Some clouds may
persist to the lee of the lake. Temperatures will recover with
some slight warm air advection and the snow across the region
having melted with a mix of 40s to lower 50s for highs.
Temperatures will drop into the 30s on Thursday night and at
least widespread frost is possible as the atmosphere decouples
with high pressure.

&&

.SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/...
High pressure lingers across the area with a high pressure ridge
extending across northern Ohio and Lake Erie through Friday night.
This will result in mostly sunny/clear skies with near normal
temperatures.

Two upper-level troughs are progged to impact our region Saturday
onward: one that moves from the lower Great Plains to the mid-
Atlantic, and another one that moves across the Great Lakes region.
These two troughs will result in a large area of surface low
pressure extending from the mid-Mississippi Valley to upper Midwest
moving eastward across the region Saturday through early Sunday. Two
defined low pressure circulations will likely be present but the
more dominant of the two for our region will move eastward across
the Ohio Valley Saturday afternoon through early Saturday night.
Isentropic lift associated with the TROWAL will provide the lift and
moisture necessary for widespread rain north of the low pressure
Saturday through early Saturday night.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
An elongated area of surface high pressure will work its way east
across the region Sunday through Monday, with the center of the high
pressure ridge centered over the region by Monday morning. This will
usher in below normal temperatures for Sunday and Sunday morning,
with a round of frost/freeze expected Sunday night as temperatures
dip to near or below freezing. As high pressure shifts to the east
this Monday/Tuesday, a big pattern flip is expected with well above
normal temperatures expected by Tuesday/Wednesday. Most areas have
forecast max temperatures in the upper 70s to low 80s for each of
these days.

&&

.AVIATION /06Z Thursday THROUGH Monday/...
Scattered snow showers continue across the eastern half of the
area early this morning, mainly impacting YNG/ERI, though a
stray snow shower or two may arrive at CLE within the next hour.
Expect MVFR to IFR vsbys in any passing snow showers at the
aforementioned sites through the next several hours, before
snow quickly diminishes by sunrise. VFR should prevail for much
of the rest of the TAF period, though some isolated rain showers
may pass near MFD/CAK in the afternoon. The best chance for any
precipitation appears to be at ERI later this afternoon into
the evening, associated with some lake effect snow. Added in a
prob30 for bursts of IFR vsbys snow for now.

Winds are generally from the west early this morning, around 10
knots. Winds will remain west to northwesterly through the TAF
period, increasing towards 15 knots by later this afternoon.
Winds may be gusty at times later this afternoon across the TAF
sites, 20 to 25 knots, with perhaps some higher gusts of near 30
knots at CLE/ERI.

Outlook...Non-VFR expected with widespread rain Saturday
afternoon through Saturday night.

&&

.MARINE...
Elevated northwest winds of about 15-20 knots will remain across
eastern Lake Erie through this evening, for which we have a Small
Craft Advisory still in effect. There will be a bit of a lull in
Lake Erie conditions before it increases back to 15-20 knots for all
of Lake Erie east of the islands through Thursday evening. Another
round of Small Craft Advisories will probably be needed for this.
This shifts to out of the southwest on Friday as high pressure moves
eastward south of Lake Erie. Winds become light and more variable
Friday night through early Sunday as low pressure moves across the
region.
