Area Forecast Discussion
National Weather Service Cleveland OH
145 PM EDT Fri Oct 7 2022

.SYNOPSIS...
High pressure builds in from the west across the Ohio Valley
through this weekend and to the mid-Atlantic region by Monday.
A weak front will cross the Great Lakes on Monday. High
pressure will back in on Tuesday before a warm front lifts north
across the area on Wednesday.

&&

.NEAR TERM /THROUGH SATURDAY/...
9:30 AM Update...
Only minor tweaks made to the temperature forecast for tonight.
Freeze Watch remains intact, will likely upgrade to an area of
Freeze Warnings later this afternoon (area remains undetermined
at this point). Most model guidance has minimum temperatures
down to 32 with a strip of clearing for parts of northwest Ohio.
It's not a guaranteed freeze though as temperatures are fairly
marginal and some model guidance has residual 850mb moisture,
with some potential for clouds to clear tonight and then come
back in from the west sometime Saturday morning (warmer minimum
temperatures are possible if clouds cover come back in before
12Z).

Previous Discussion...
A cold front continues through the forecast area this morning,
dropping temperatures into the 50s and shifting winds to the
northwest across the area. Rain and lower clouds are largely
occurring behind the front, as both better moisture and lift are
present and better thermodynamics are in place with some lake
induced instability and moisture. Certainly will not be a wash
out across the area this morning, but suspect that most of the
northern counties will get a few hundredths of rain as a band of
rain moves through the forecast area and have restored some
higher PoPs to the forecast. As the front pulls away from the
area, rain will become more scattered today and more tied to
lake effect processes as cold air advection surges in with a
fetch across a warm Lake Erie in the lower 60s. Therefore, have
some chance PoPs for today, especially for NE OH and NW PA. Rays
will be hard to come by today with lake clouds behind the front
guarding the area from the sun. These clouds, along with the
cold air advection regime behind the cold front, should keep
temperatures down and high temperatures for the day likely
already occurred at midnight, but daytime temperatures should be
stagnant in the lower 50s.

For tonight, clouds will start to disappear across portions of
Northwest and North Central Ohio as drier air and high pressure
build into the region. While the surface high will be to the
west and a slight pressure gradient will be across the area to
keep some light wind, conditions should be favorable enough for
temperatures to drop into the lower 30s and widespread frost
should develop over the western half of the area. Therefore,
have issued a Freeze Watch for 2 AM to 10 AM Saturday. Frost
potential decreases into Northeast Ohio and Northwest PA with
clouds still off the lake and will allow another forecast cycle
to determine the more conditional Frost Advisory areas for
tonight.

Some low level ridging and surface high pressure building in
from the southwest will start to disrupt the lake effect clouds
and rain tonight into Saturday, as some warmer temperatures
aloft enter and mean low level flow shifts from the northwest to
west. Have tapered some chance PoPs tonight for NE OH/NW PA to
just slight chance for Saturday. Saturday's high temperatures
could be slightly improved into the mid 50s during the day for
some.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
During the short term period, high pressure will push north from the
south, allowing for winds across Lake Erie to become southwest and
shift any lingering lake effect rain potential out of the area. This
high pressure will also bring much drier air to the region, with
dewpoint temperatures dropping into the low 30s through Monday
afternoon. These factors will keep the area dry through the short
term period. With the shift to southwest winds, warm air advection
will allow temperatures to gradually begin to climb with highs on
Sunday and Monday reaching into the low to mid 60s. Overnight lows
Saturday night will be in the mid to upper 30s for much of the area,
but temperatures along the lakeshore will remain in the 40s. These
low temperatures mixed with lighter winds may allow for areas of
frost to develop. On Sunday and Monday night, temperatures will be a
bit warmer with lows only dropping into the upper 30s to low
40s.

&&

.LONG TERM /TUESDAY THROUGH THURSDAY/...
The aforementioned high pressure that kept the area dry during the
short term period will gradually drift off the Mid-Atlantic Coast by
Tuesday night. By Wednesday morning, another trough will begin to
dig south across the north-central United States. A cold front will
extend along the spine of this trough and begin to gradually shift
east towards the region. On Wednesday, a warm front associated with
this system will shift north across the area, allowing for possible
showers to develop along and ahead of the boundary. Behind this warm
front, temperatures will continue to rise resulting in Wednesday's
high temperatures reaching into the upper 60s to low 70s across the
area. The aforementioned cold front will move across the area on
Thursday, bringing plenty of moisture and widespread showers with
it. As the boundary moves through temperatures will cool and only
reach into the low to mid 60s on Thursday. Overnight lows
temperatures will follow a similar pattern with Tuesday night being
in the mid 40s to low 50s, increasing on Wednesday night into the
low to mid 50s.

&&

.AVIATION /18Z Friday THROUGH Wednesday/...
Lake effect cloud cover continues to produce widespread ceilings
in the 2500 to 4000 ft range through this afternoon evening.
Moisture coverage (and thus cloud cover) is reduced for parts
of northwest Ohio by tonight. Lake effect rain showers will also
be possible, with light returns already being observed on radar
this afternoon. Lake effect showers should pick up this evening
into tonight as colder air aloft arrives. MVFR ceilings become
more prominent with lake effect rain tonight, largely in north-
central and northeast Ohio tonight, shifting eastward to
northwest Pennsylvania for Saturday morning.

Northwest winds of around 10 knots continues through this
afternoon, diminishing to around 5 knots overnight, except near
the lakeshore where winds of 8-10 knots could be possible. Winds
increase back to 8-12 knots Saturday afternoon out of the west.

Outlook...Non-VFR ceilings from lake clouds may linger across
NE OH into NW PA into Saturday night.

&&

.MARINE...
A strong cold front moving across Lake Erie this morning has
resulted in winds shifting to become north-northwest at 15-20 knots.
The strong onshore flow will allow waves to build 4-6 feet through
this afternoon, persisting for the central basin into the first half
of tonight. As a result, a Small Craft Advisory remains in effect,
but has been extended for all zones. The eastern and western basins
are now in effect into the afternoon and the central basin through
early tonight. As high pressure begins to push across the region
tonight, winds will initially remain out of the north-northwest, but
weaken to 10-15 knots. On Saturday, the aforementioned high pressure
will continue to push east towards the Mid-Atlantic Coast allowing
for west-southwest winds to develop across the lake. Increased
pressure gradient over the lake due to a low pressure north of the
region will result in winds of 15-20 knots, possibly touching 25
knots in the open waters. These conditions will persist into Sunday
morning and may be the next period that would require a Small Craft.
By Sunday afternoon, high pressure will push north across the lake,
weakening the pressure gradient and allowing west winds of 5-10
knots to occur through Monday. Waterspouts should not be a problem
through the weekend as strong winds, lack of moisture, and less than
optimal delta-T between the lake and 850mb should prevent any
development.
