AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
934 PM EDT Fri Oct 4 2024
.SYNOPSIS...
Dry conditions will continue through Saturday as high pressure
pushes across the Great Lakes. A few showers and thunderstorms
will be possible on Sunday thanks to a cold front trailing
Canadian low pressure. Dry weather is forecast to return for the
remainder of next week as high pressure builds across most of
the United States.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
Surface high pressure resides over the region once again
tonight. Mostly clear skies, light winds will help produce some
river valley fog once again, but not expecting any dense fog
from this. A slight increase in dewpoint temperatures will keep
lows primarily in the 50s tonight.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/...
Dry weather will prevail through the period as high pressure
moves to the Atlantic Coast. Increasing southerly winds will be
observed by Sunday morning as the pressure gradient tightens
ahead of the next cold front. Above normal temperatures are
forecast to persist, with highs reaching the mid 70s to around
80, followed by lows in the 50s.
&&
.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
A cold front attached to a strong low in Canada progresses through
the Ohio Valley on Sunday. Warm and breezy southwesterly flow ahead
of the front will cause temperatures to reach into the 80s areawide
before FROPA later Sunday afternoon. Some degree of moisture return
ahead of the front appears likely with dew points and PWATs reaching
above seasonal averages. This moisture increase could allow for some
instability ahead of the front. Low end chances for a few
showers/thunderstorms are highlighted especially across central Ohio
through southeast Ohio Sunday afternoon.
Temperatures drop after FROPA Sunday night and high pressure will
build in through at least mid-week. Highs next week generally remain
near 70 areawide with lows in the middle 40s under abundant
sunshine. Beyond the low end chances for precipitation on Sunday,
dry conditions appear highly likely through the week.
&&
.AVIATION /02Z SATURDAY THROUGH WEDNESDAY/...
VFR conditions expected through the taf period at every terminal
except KLUK. River valley fog potential remains tonight, but not
expected to be quite as dense. Still have an MVFR mention, but
went with a TEMPO IFR mention given the weaker signal present
for tonight.
There will be a wind shift through the taf period as
north-northeasterly winds will shift to the southeast by the
late morning/early afternoon hours Saturday. Some cu development
possible as well.
OUTLOOK...No significant weather expected.
