Area Forecast Discussion
National Weather Service Cleveland OH
632 AM EDT Thu Apr 1 2021

.SYNOPSIS...
A surface trough will cross the region this morning followed by
a weakening cold front this afternoon. Strong high pressure
will spread over the region from the northern Plains tonight.
This high will impact the region into Friday night. A warm
front will move across the area on Saturday and will wobble
near the central Great Lakes into early next week.

&&

.NEAR TERM /THROUGH FRIDAY/...
First round of moderate snow is beginning to decrease in
coverage and intensity as it drifts further inland away from
Lake Erie. We have had reports of 1 to locally 4 inches from
Huron County into NW PA. The 4 inch report was over southeastern
Huron County. Since the accumulating snow is about done in that
area we will not hoist any headlines.

Snow showers will become isolated to scattered by mid morning
and persist into early/mid afternoon. We then should see a
slight uptick as a reinforcing surge of cooler air arrives by
late afternoon into the early evening. So we will see an
increase of snow showers moving to the southeast off the lake
from the Port Clinton area eastward to the NY/PA border. Believe
these snow showers will have a hard time accumulating during
the day but we will have to watch where they are the most
persistent. Would not be surprised to see a few Special Weather
Statements to cover the heavier snow showers with reduced
visibilities for late afternoon/early evening. Highs today will
mostly be in the 30's. Unfortunately the wind will create brisk
conditions with wind chill values in the teens to lower 20's
through the day.

Snow showers should decrease fairly fast this evening but we do
think some lake effect snow flurries will continue through at
least 10 pm. Beyond that time high pressure should begin to
increase its influence with plenty of dry air spreading into the
region. Lows tonight will range from the upper teens across
inland NW PA to the mid/upper 20's.

Friday will be a dry day with lots of sunshine expected. All
the sunshine will help to warm temperatures. Highs will range
from the mid 30's across inland NW PA to the upper 40's across
NW OH.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/...
Primarily fair weather is expected Friday night through Saturday
night. Aloft, a ridge builds slowly from the west. At the surface, a
ridge crests over our CWA Friday night as low temperatures reach the
lower 20's to lower 30's. Milder temperatures are expected Saturday
and Saturday night as low-level WAA takes hold on the backside of
the eastward-moving surface ridge. Saturday afternoon's highs should
reach the 50's to lower 60's and be followed by lows in the upper
30's to lower 40's Saturday night. A few rain showers are possible
Saturday evening into early Sunday morning, especially in northwest
PA, as a subtle shortwave trough ripples through the northwesterly
flow aloft and is accompanied by a weak surface trough passage.

Ridging aloft continues to build slowly from the west Sunday and
Sunday night, allowing northwesterly flow aloft to persist. At the
surface, ridging rebounds over our region and should allow fair
weather to return to the whole CWA. A weak MSLP gradient should
contribute to lake breeze development along and near the Lake Erie
shore during the afternoon through early evening. Highs should range
from the mid to upper 50's along and near the lakeshore to the lower
to mid 60's farther inland. Lows should reach the mid 30's to lower
40's Sunday night.

&&

.LONG TERM /MONDAY THROUGH WEDNESDAY/...
Weak surface ridging and fair weather should persist Monday as high
pressure aloft continues building from the west. A weak MSLP
gradient may once again allow a lake breeze to occur along and near
the Lake Erie shore by afternoon and continue into the early
evening. Highs should range from the upper 50's along the lakeshore
to the upper 60's to lower 70's farther inland. Scattered showers
are possible Monday night as a surface low moves across the northern
Great Plains toward the western Great Lakes and allows a surface
warm front to sweep northeastward through our CWA. Aloft, the ridge
crests over our region as a shortwave trough approaches from the
northwest. Lows should reach the 40's to lower 50's.

Forecast confidence decreases Tuesday through Wednesday as notable
model discrepancies exist. Westerly to northwesterly flow aloft and
embedded shortwave disturbances may affect our CWA. At the surface,
the low may move east-southeastward from the western Great Lakes to
open Atlantic waters well-offshore the Mid-Atlantic states. This low
track may allow the trailing cold front to drift southward toward
the OH Valley. Frontal forcing for ascent and a low-level return
flow of moist and unstable air from the Gulf of Mexico undergoing
isentropic ascent aloft, ahead of the front, may allow periods of
showers and thunderstorms to occur. Afternoon highs may reach the
60's to lower 70's both days. Lows may reach the mid 40's to lower
50's Tuesday night.

&&

.AVIATION /12Z Thursday THROUGH Monday/...
VFR conditions are being reported across NW OH. However further
east in the snow showers MVFR/IFR conditions are being observed.
This first round of snow showers will continue to drift to the
southeast through mid morning with ceilings improving. Any
remaining snow showers through early/mid afternoon will become
isolated/scattered with MVFR/IFR conditions in them. Another
surge of moderate snow showers will move across the central and
eastern portions of northern OH into northwestern PA by late
afternoon and then progress southeast through early evening.
MVFR/IFR coverage area will increase with the uptick in snow
showers. After 02Z conditions should begin to improve with a few
flurries remaining until maybe 04Z across NE OH into NW PA.

Northwesterly winds will persist through the forecast period.
Most locations will see speeds between 8 and 15 knots with gusts
25 to 30 knots possible. Strongest gusts will be near the lakeshore.

Outlook...Non-VFR possible in rain showers across NW PA Saturday
night.

&&

.MARINE...
A Small Craft Advisory remains in effect west of Vermilion until 10
AM Friday. East of Vermilion, the Small Craft Advisory remains in
effect until 2 PM EDT Friday.

A cold front will sweep southward across Lake Erie this afternoon
through early evening. Otherwise troughing persists over the lake
through tonight. Winds trend north-northwesterly at 15 to 25 knots,
but should increase toward 30 knots with the frontal passage and for
several hours following the front. Waves as large as 4 to 8 feet are
expected through this evening, especially in the central and eastern
basins. Waves should subside to 5 feet or less by daybreak Friday.
Northwesterly winds of about 10 to 15 knots are expected on Friday
as high pressure builds from the west. Waves subside further to 3
feet or less by nightfall. Northwesterly winds of about 5 to 10
knots back to southwesterly Friday night as the ridge crosses Lake
Erie from west to east. Waves subside to 2 feet or less.

Southwesterly winds increase to about 10 to 15 knots Saturday as a
trough approaches from the northwest and interacts with the
departing ridge. Waves should trend 1 to 3 feet. Southwesterly winds
of 10 to 15 knots shift to westerly Saturday night with the
southeastward passage of the trough. Waves remain 1 to 3 feet.
Variable winds of 10 knots or less are expected Sunday through
Monday as high pressure reestablishes itself. Waves of 2 feet or
less are likely.
