.SYNOPSIS...
Low pressure over the Northern Plains will lift a warm front
northeast across the region today. Another low pressure system
moves across the Ohio Valley Friday night and will drag a cold
front east on Saturday. High pressure builds across the area
Sunday through Tuesday.

&&

.NEAR TERM /THROUGH FRIDAY/...
Upper level ridge will move east across the eastern Great Lakes
today as an upper low over the Northern Plains moves into the Great
Lakes region. The surface low will lift a warm front northeast
across the local forecast area during the day today advecting in a
warm and moist airmass. There`s a low chance for some isolated
showers and thunderstorms across eastern zones this afternoon as an
upper level trough lingers through this afternoon. Otherwise the
daytime hours should largely remain dry under the upper ridge.

A broken line of convection ahead of a cold front develops upstream
today before moving east across portions of Michigan, Illinois,
Indiana and entering western Ohio tonight. These upstream discrete
cells will evolve into a broken line as it approaches the local
forecast area. The latest CAMs indicate that this organized line
will be entering an environment characterized by MLCAPE upwards
of 2500 J/kg, 7.5 C/km mid level lapse rates, roughly 35-40
knots of bulk layer shear, and 300 m2/s2 of sfc-1km SRH. All
severe weather hazards including, damaging wind gusts, large
hail, and a few embedded tornadoes along the line, are possible.
General arrival time for strong to severe storms will be
roughly 8-10 PM along the I- 75 corridor, 10 PM-12 AM across
north-central Ohio, and 11 PM-1 AM across Northeast Ohio and
Northwest Pennsylvania. To cover the severe weather threat, the
SPC has highlighted all of our Ohio Counties in a Slight Risk
(Level 2/5) SWODY1.

Initial round of showers and thunderstorms will exit early
Friday morning as the cold front exits to the east. Another
round of showers and thunderstorms, with the potential for
strong to severe thunderstorms, enters from the southwest as low
pressure lifts across the Ohio Valley. Showers and storms will
likely enter near or after sunset Friday night, similar to the
Thursday night into Friday morning severe weather threat.

Afternoon highs today and Friday will rise into the mid 80s today
with dew points in the upper 60s. Warm overnight lows tonight in the
mid to upper 60s.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/...
At the onset of the short term Friday night, will see a sharp uptick
in the frontogenesis with the cold front moving into northwest Ohio,
and shower/thunderstorm activity increases. Upper level low
traverses the Great Lakes west to east with a secondary cold front
coming through early Saturday. This secondary cold front will have
the more significant low level cold air advection along with an
infiltration of low level moisture from the counterclockwise flow of
the upper level low. Expect variable cloud cover through the weekend
and temperatures cooling significantly from the Thursday and Friday
values and highs in the 60s by Sunday.

&&

.LONG TERM /MONDAY THROUGH WEDNESDAY/...
Upper level low departs with weak ridging for early next week. This
becomes a drier pattern for the area until another upper level low
ejects from the southwestern US into the central plains region.
Associated surface low moves into the Ohio Valley tracking west to
east just south of the CWA, with moisture slung far enough northward
for POP increases midweek.  Temperature recovery will be slow but
steady after Sunday, and back into the lower 70s for most
locations Wednesday.

&&

.AVIATION /06Z Thursday THROUGH Monday/...
Scattered showers and thunderstorms, mainly across western
terminals, will continue throughout the next few hours.
Generally dry weather is expected across terminals on Thursday,
though can`t rule out an isolated pop up shower/thunderstorm
Thursday afternoon across eastern terminals. A cold front will
approach terminals from the west late Thursday night near the
end of the TAF period. Have introduced PROB30 groups for TSRA
moving across terminals from west to east. There is the
potential for strong to severe storms as the cold front moves
east.

Southerly winds 5-10 knots will continue through the TAF period
outside of the development of a lake breeze this afternoon
which may flip winds easterly to northeasterly along the Lake
Erie lakeshore.

Outlook...Periodic showers and thunderstorms with non-VFR are
possible through Saturday.

&&

.MARINE...
Southeast winds this morning 5-10kts gives way to another east
northeast lake breeze this afternoon. Waves less than a foot become
around a foot in the more onshore flow before becoming southwesterly
tonight 10-15kts. A series of cold fronts come through Friday,
Friday night, and early Saturday. The last cold front will be the
one with the most significance of wind direction changes to the west
on Saturday 15-25kts. East of Cleveland, expecting wave heights
during this period to increase to 3-5ft in the nearshore zones, and
2-4ft west. Sunday through Monday, wave heights become 1-3ft as
onshore winds decrease to 10kts by Monday.
