expected Saturday night through Sunday associated with the remnants
of Isaias.

2) A cold front will bring the next chance for showers and thunderstorms
on Tuesday.

.DISCUSSION...
KEY MESSAGE 1...
The remnants of Hurricane Isaias will move north into the Ohio
Valley Saturday night through Sunday, resulting in periods of
moderate to heavy rain across the region, especially late
Saturday night into Sunday morning. Additional periods of
moderate to heavy rain are possible Sunday morning and
afternoon, mainly along and east of the I-71 corridor as the
remnants of Isaias gradually move east towards the Mid-Atlantic
Coast. Rainfall amounts have increased slightly in this forecast
package, especially along and east of the I-71 corridor where
totals may range between 1 to 2 inches. The latest REFS
guidance, albeit somewhat aggressive, also indicates a low
probability (20 to 30%) for a narrow swath of 3 inches of rain,
though this is likely the "worst case" scenario. The overall
threat for flooding is still considered to be low due to recent
dry conditions and low stream/river levels.

In addition to the widespread rain, a potent southeast low-level jet
will bring breezy conditions into the region, with wind gusts
primarily in the 25 to 35 mph range, though can`t rule out isolated
higher gusts up to 40 mph, especially in the favored downsloping
areas.

KEY MESSAGE 2...
The next chance for precipitation will be on Tuesday as a cold
front moves southeast through the Great Lakes. A narrow corridor
of weak instability may form ahead of the front as surface dew
points increase into the low 60s which could support a few
thunderstorms. Can`t rule out a few stronger storms given the
ample mid-level shear in place, approaching 40 to 50 knots at
times Tuesday afternoon.

.AVIATION /06Z Saturday THROUGH Wednesday/...
VFR conditions will continue through the TAF period for all
terminals except KCLE, which will see deteriorating conditions
after 06Z tomorrow with rain showers. Mid to high level clouds
are expected through the day today across the region. Winds will
be out of the southeast at 120-140 at 5-10 knots throughout the
period. KERI will see elevated winds gusting to above 20 knots
after 00Z due to downsloping. KCLE will begin gusting above 20
knots out of 130-140 after 06Z tomorrow.

Outlook...Non-VFR conditions in moderate to heavy rain showers
expected early Sunday lingering into the evening. Non-VFR
possible again on Tuesday with showers and thunderstorms.


&&

.MARINE...
Generally quiet marine conditions are expected through Saturday with
offshore flow of 10 to 15 knots. Southeast flow will increase into
the 15 to 20 knot range on Sunday as the remnants of Isaias
move north into the Ohio Valley, though not anticipating any
marine headlines at this time. Winds will shift towards the
northwest on Monday, 10 to 15 knots, as Isaias moves east of the
Mid- Atlantic coast. Winds will again increase out of the
southwest ahead of a cold front on Tuesday, 15 to 20 knots,
shifting towards the northwest behind the front late Tuesday
into Wednesday, 15 to 20 knots. A Small Craft Advisory will
likely be needed behind the front.
