Area Forecast Discussion
National Weather Service Cleveland OH
1253 AM EDT Thu Sep 21 2017

.SYNOPSIS...
High pressure builds in across the region tonight. This area of
high pressure will remain anchored over the area into the
beginning of next week.

&&

.NEAR TERM /THROUGH THURSDAY/...
Dry weather is expected for everyone through Thursday night. While a
stray shower cannot be completely ruled out across far eastern Ohio
into northwest Pennsylvania Thursday afternoon, the odds are too
small to include in the forecast.

Areas of fog will develop tonight and it may be dense in spots
with visibilities dropping to below 1/4 mile at times. Best
chances will be inland and across locations that have recently
seen rain, such as the Toledo area.

Temperatures will warm to well above normal again Thursday
afternoon with highs in the middle and upper 80s. Considering
how dry it has been over the past month, would not be too
surprising to see someone touch 90 degrees.

Fog may develop again Thursday night across much of the same
areas.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/...
High pressure at the surface and aloft are expected to dominate the
region through the short term. Unseasonably warm temperatures are
expected Friday through Sunday. Cooler near the lakeshore each
afternoon as a lake breeze develops.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
A highly amplified upper level pattern across the CONUS will
leave the eastern CONUS under a strong ridge Sunday night
through Tuesday night. This will provide dry conditions and
above normal temperatures to the local area. Highs in the low to
mid 80s are expected Monday and Tuesday, with slightly cooler
temps on Tuesday. A cold front will push east into the area by
Wednesday night, which could provide some showers and
thunderstorms to the area beginning Wednesday afternoon through
Wednesday night. Temps will be slightly cooler on Wednesday just
ahead of the cold front, with highs in the upper 70s to low
80s.

&&

.AVIATION /06Z Thursday THROUGH Monday/...
Mostly clear skies and light winds should allow MVFR to local IFR
fog to develop into daybreak then dissipate from 13z to 15z. Some of
the cirrus from convection to the west may spread into the TOL and
FDY areas this morning, otherwise expect sct to locally bkn cu to
develop with daytime heating then dissipate into sunset. Winds will
remain light with an afternoon lake breeze affecting ERI and CLE.

OUTLOOK...Non-VFR possible in fog Friday and Saturday mornings.

&&

.MARINE...
High pressure will continue to control the region through Sunday.
Winds will be light. However, onshore winds may increase to
around 10 knots each afternoon as the lake breeze circulation
sets up.

&&
