.SYNOPSIS...
A stationary front will gradually lift north on Wednesday as low
pressure moves northeast through the Great Lakes, extending a cold
front through the area on Thursday. This cold front will stall and
linger near the Lower Great Lakes into the weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
Main concern for the near term period will be the potential for
showers and thunderstorms Wednesday afternoon and evening,
particularly across Northwest Ohio where a couple of stronger
storms are possible.

For the rest of today, weak high pressure is resulting in mostly
sunny and seasonable temperatures. No precipitation is expected
through this evening, though some pockets of dense fog are
possible across far Northeast Ohio and Northwest Pennsylvania
overnight. Otherwise, a weak mid- level shortwave is currently
located across southern IA/northern MO. This feature will gradually
move east towards the Lower Great Lakes into Wednesday, providing
mesoscale enhancement, in addition to weak upper- level forcing
from a passing trough. The latest HREF indicates mostly scattered
coverage of showers and storms across portions of Southeast MI
and Northwest OH Wednesday afternoon and evening. The environment
is suggestive of modest downburst potential across Northwest
Ohio, with values behind the DCAPE gradient around 800 to 900
J/kg and low-level lapse rates between 7 to 8 C/km. Bulk shear
values around 20 to 25 knots could also support a few organized
thunderstorm clusters. This potential is reflected in the most
recent SPC SWODY2 marginal risk.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
Periods of afternoon and evening showers and thunderstorms will
remain possible for the short term period, with the highest
coverage found along a cold front across the southeast portion
of the area on Thursday. Shower and storm chances appear less
likely, or at least more isolated, on Friday in the wake of the
cold front and as weak high pressure attempts to build south
through the Great Lakes. Mainly seasonable to slightly above-
average temperatures are expected for Thursday and Friday with
highs in the mid to upper 80s. Heat indices may begin to
approach the lower 90s by Friday.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
Active weather appears to continue for the weekend and perhaps
even into early next week as a stronger upper-level trough moves
east through the Upper Great Lakes on Saturday into Sunday,
extending a cold front across the area. The latest guidance
suggests the potential for perhaps some organized convection on
Saturday with the trough passage, although uncertainty remains
on the timing of the cold front. Depending on the timing of the
cold front, Sunday could either feature additional chances for
showers and storms, particularly across the southeast portion
of the area, or favor dry weather as high pressure attempts to
build behind the front. However, the brief respite in the active
pattern does not appear to remain as modest westerly flow
returns across the Great Lakes region, on the northern periphery
of a building ridge to the south.

The hottest day of the long term period is expected to be
Saturday with heat indices approaching the mid to upper 90s
prior to any shower and storm development later in the day.
Slightly above-average temperatures are then expected to
persist for Sunday and beyond with highs in the mid to upper
80s. Heat indices may approach the lower 90s each afternoon.

&&

.AVIATION /06Z Wednesday THROUGH Sunday/...
Weak low pressure is over Lower Michigan at 06Z with a moisture
axis extending southwest across Indiana. Showers with isolated
thunderstorms are ongoing across SE Michigan and develop west
of Toledo. While eastward progress is expected to be slow, can
not rule out a shower in the vicinity of TOL though about 09Z.
Most location will see a mix of mid and high level cloud
overnight with the potential for MVFR visibilities developing
late tonight towards TOL where moisture advection is occurring
and in favored sites in NE Ohio where low level moisture remains
high with only scattered clouds.

The challenge today will be timing scattered showers and
thunderstorms. Thunderstorms have the best chance of occurring
at TOL between 20-23Z while confidence is lower at CLE/FDY/MFD.
Will carry a prob30 at those locations with just a vicinity
shower at CAK by early evening. Wind gusts of at least 20-25
knots are possible with thunderstorms but may need to amend to
add higher wind gusts of 40+ knots if a strong thunderstorm
develops, mainly in NW Ohio. MVFR and brief IFR visibilities are
possible with thunderstorms.

Winds will be southwesterly today, generally ahead of
thunderstorms. The trough moves southeast later today and may
result in a wind shift to the north at northern terminals or
downwind of Lake Erie while winds will tend to be light and
variable again tonight.

Outlook...Non-VFR will be possible with scattered showers and
thunderstorms Thursday through Sunday with the best chance
during the afternoon each day.

&&

.MARINE...
Overall, good marine conditions are anticipated over the next
several days. Winds will generally be southerly at around 10
knots or less through Wednesday before briefly shifting to the
northwest behind a cold front Thursday. A period of onshore flow
due to a lake breeze is likely on Wednesday afternoon. Variable
and relatively light winds in addition to periods of onshore
flow due to daily lake breezes are favored Thursday afternoon
through Friday with winds becoming more south/southwesterly and
increasing to around 10 knots on Saturday.

Periodic showers and thunderstorms are possible on the lake
Wednesday through the weekend, best chance during the afternoon
and early evening each day. Winds and waves could be higher in
thunderstorms.
