Area Forecast Discussion
National Weather Service Cleveland OH
629 PM EDT Wed Sep 5 2018

.SYNOPSIS...
Low pressure will move across Quebec tonight with a cold front
sagging southward through the central Great Lakes. This cold
front will move southward across the region on Thursday,
reaching central Ohio by late afternoon. The front will stall
across near the Ohio River Valley then lift back to the north
as the remnants of Tropical Storm Gordon approach the area.

&&

.NEAR TERM /THROUGH THURSDAY NIGHT/...
Bumped up pops to scattered North Central Ohio for this evening.

Original discussion...
Low pressure will move across Quebec tonight with a cold front
sagging southward through the central Great Lakes. This cold
front will move southward across the region on Thursday,
reaching central Ohio by late afternoon.

For the  remainder of this evening there will be isolated
thunderstorms. The exception looks to be the Mid Ohio region
where a slightly better plume of moisture and a piece of 5H jet
energy interact to generate scattered thunderstorms. This piece
of jet energy moving northward overnight may keep a few
thunderstorms going across the eastern half of the region. We
will also have to monitor along the cold front for additional
development. Anything that does develop along the front will
drift southward and clear the region by late afternoon/early
evening.

One more humid night tonight then gradually drying out through
the Thursday evening. It will be cooler on Thursday with the
frontal passage and additional cloud cover. Highs should range
from the mid to upper 70s near the lakeshore to the lower 80s
south. Temperatures Thursday night will remain above seasonal
averages with middle 60s common. Slightly warmer near the
lakeshore.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
Upper level ridge is expected to build to the lee of the Rocky
Mountains by the early part of the weekend. The ridge has a
potential to have an impact on where the tropical remnants
tracks. Strong surface high pressure building south out of
northern Ontario, Canada will push dry air into the region
during the early part of the forecast period. Expecting there to
be a sharp cutoff between rain and no rain over Ohio and
Pennsylvania Friday and Saturday. The high pressure will then
shift slowly east allowing remnants to move east into Ohio by
Sunday morning. The gradient between the two systems will
tighten over the eastern third of the forecast area with winds
pushing 15 to 25 knots. Rest of the area will see lighter winds
closer to the center of circulation. Abundant tropical moisture
will begin to surge north with the system as well and the best
chance for any rain appears it will arrive Sunday morning.
Instability does not look that impressive and should remain
stable enough to only support showers with the system as it
moves into the region. Temperatures will be considerably cooler
over the weekend with the threat for the showers and cloud
cover. Cool air advection from the effects of the high pressure
to the north will aid in keeping cool air in place as well. Some
slightly warmer air will arrive Sunday as tropical air arrives
with the remnant system.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
The long term begins Sunday night with models in agreement showing
low pressure just to our west, the remnants of Gordon.  The GFS has
the low from Central Indiana to northwest OH while the ECMWF is
centered in eastern IL. Either way, deep moisture will be across the
region with it's origin in the tropics. Will begin with categorical
pops across the entire area and then drop pops to chance/likely
west/central. Monday the low will track northeast across the
central Great Lakes taking much of the tropical moisture with it.
Will need to continue with likely pops east for lingering showers
but will drop to chance elsewhere. Tuesday will be dry as both the
GFS and ECMWF bring high pressure and drier air in from the west.
Wednesday the high will move to eastern Quebec but should extend a
ridge west across the central lakes into the Mississippi Valley.
Should be a decent day but the resultant easterly gradient will
bring enough moisture back into the area from the east. Will
therefor need a slight chance pop east and central counties.

&&

.AVIATION /18Z Wednesday THROUGH Monday/...
Scattered -tsra North Central Ohio will gradually diminish this
evening. Expect more scattered convection after midnight ahead
of approaching cold front that will move across forecast area
tomorrow.

OUTLOOK...Non-VFR possible late Saturday night into Sunday in
showers and isolated thunderstorms.

&&

.MARINE...
Winds on the lake expected to be relatively light this evening.  A
northerly flow will develop late tonight as a cold front slips south
across the area.  As high pressure builds slowly east across
Ontario, Canada, the remnant tropical system will slowly push into
Ohio and Pennsylvania.  The two systems will increase the gradient
over the lake and winds will become gusty Saturday evening into
Sunday night.  Sustained winds 25 to 30 knots will not be out of the
question and possibly higher depending on the track of the remnant
low pressure system.  Winds do shift around to the and begin to
diminish Monday behind the storm system.
