area forecast discussion

937 pm edt Mon aug 19 2019

Synopsis
A weak area of high pressure over the area will move east of
the region overnight. A stationary front south of the area will
lift back north across the area as warm front Tuesday morning. A
cold front will move southeast across the local area Wednesday
evening. A ridge of high pressure will build southeast across
the area Thursday. High pressure will be centered over the local
area Friday night.

Near term through Tuesday night
Just added some patchy fog to the forecast for some of the
interior counties for late tonight into early Tuesday. With
mostly clear skies and light winds, wouldn't be surprised to
see the atmosphere decouple and allow for fog development. Some
mid level clouds moving in from the west may abate dense fog
development, but typical low spots may see some lower
visibilities.

Previous discussion...

a cold front remains north of the forecast area this evening as
the area remains in the warm sector with temperatures in the
upper 70s and lower 80s and dew points in the upper 60s to lower
70s. Diurnal cumulus that was along a weak former lake breeze
boundary has dissipated across the region and most folks should
see clear skies tonight.

The area remains in the warm sector for Tuesday as a mid-level
wave approaches the region from the west. This will be the
forcing for shower and thunderstorm development on Tuesday. The
area appears fairly unstable with warm temperatures in the 80s
and fairly good low-level lapse rates. The shear over the area
is not as good as areas north and west, so that will be somewhat
of a limiting factor for thunderstorm coverage and severity.

Will have increasing pops on Tuesday with a mid-chance pop to
indicate scattered coverage. The mid-level wave does not pass
the area until Tuesday night and will keep pops into the later
part of the forecast period.

Short term Wednesday through Thursday night
A broad upper level trough over western canada will dig south into
the great lakes new england regions Wednesday through Thursday
night. A surface low just north of the great lakes Wednesday will
deepen and move northeast into quebec as a strong shortwave rounds
the base of the trough through the northern great lakes Wednesday
night, forcing a surface cold front south of the area.

Shower thunderstorm chances will peak diurnally on Wednesday with
weak destabilization ahead of the cold front, although kept pops in
the low mid chance range with the best forcing remaining northeast
of the area and southwest of the area as a convectively induced
shortwave tracks east through the ohio valley. The front will settle
just south of the forecast area Thursday into Thursday night as high
pressure tries to build south from western ontario through the great
lakes. Have kept the forecast dry across the area Thursday and
Thursday night, with any precip potential limited to upstream mcvs
tracking along the front, and models trending towards strong
pressure rises across the region by Thursday night. Above normal
temperatures and humid conditions Wednesday will give way to drier
and cooler conditions by Thursday.

Long term Friday through Monday
High pressure will slowly build southeast across the great lakes
Friday and Saturday into the northeast CONUS Sunday into Monday,
providing a period of cooler temperatures and dry weather over the
weekend. Highs in the 70s Friday and Saturday will slowly moderate
into early next week, with highs near normal in the low 80s Sunday
and Monday. Shower thunderstorm chances may creep back into the area
Monday as return flow ramps up and a trough approaches the region
from the west, but for now have kept pops in the slight chance range.

Aviation 00z Tuesday through Saturday
Vfr conditions expected through at least the next several hours
as high pressure sits over southwest ohio and a cold front
remains well to the north of the region. A robust lake breeze
boundary allowed for some good cumulus development, but much of
that has tapered off. Expect light and variable winds with
ceiling-free conditions. With a warm, moist atmosphere in place
over the region, some modest fog is possible across the interior
portions of the forecast area. Some mid-level clouds upstream
may try to slip into the region and abate some development, but
the air mass is muggy enough to allow a brief MVFR window.

Showers and thunderstorms are possible on Tuesday afternoon and
evening. Coverage appears very scattered at this point, so have
omitted from all tafs except kcle, where a prob30 window is
mentioned to give the best guess for timing.

Outlook... Intervals of non-vfr possible primarily with
thunderstorms possible Tuesday night through Wednesday.

Marine
A front will remain stationary near over the lake tonight, before
lifting north of the lake tomorrow into tomorrow night. Winds will
generally remain light until Wednesday, as a cold front approaches
from the northwest and winds increase out of the southwest to 10-15
kts. Winds will become northerly as the front cross the lake
Wednesday night, with winds remaining out of the north through the
end of the week as high pressure builds across the great lakes.
