Area Forecast Discussion
National Weather Service Cleveland OH
Issued by National Weather Service Buffalo NY
633 AM EDT Fri Aug 14 2020

.SYNOPSIS...
An upper level low slowly passing across the Ohio Valley will
trigger a few showers and thunderstorms this afternoon, tonight
and Saturday. A cold front will advance through the area Sunday,
ushering in much more comfortable levels of humidity for the
start of the work week. An area of high pressure will dominate
through mid week with much of the time rain-free.

&&

.NEAR TERM /THROUGH TONIGHT/...
This morning regional radars display a few showers and
thunderstorms over the warm open waters of Lake Erie. Greatest
instability, and weak surface convergence will reside over these
open waters of Lake Erie this morning...with isolated showers
and thunderstorms possible through about 12-14Z.

Elsewhere much of the region will remain dry through the morning
with a mix of clouds and sunshine.

An upper level shortwave over the Lower Ohio Valley this morning
will slowly track eastward across the Ohio Valley this period.
By this afternoon instability will be increasing with MUCAPE
values of 1000 to 1500 J/KG across far western zones and sharply
decreasing eastward. It is along this instability gradient
across western zones, and ahead of the upper level shortwave
that showers and thunderstorms will likely form this afternoon.
Activity will remain scattered...thus will maintain chance PoPs
to the west...and slight chance or lower farther to the east and
north. Upper level winds remain weak, and with PWATS around 1.5
inches to our far south...a downburst of rain will be the
greatest concern.

Isolated to scattered storms will taper down through the
evening with the loss of daytime heating. However with the upper
level low still in close proximity to our south and lingering
instability a few showers or isolated thunderstorms will remain
possible across southern zones tonight. Temperatures tonight
will be very similar to this early morning, with lows in the mid
to upper 60s.

&&

.SHORT TERM /SATURDAY THROUGH MONDAY/...
Upper level trough will shift east across the area Saturday
with an associated area of positive vorticity advection.
Moisture associated with this upper level feature is expected to
move east across the area as well by Saturday evening. A weak
wave of low pressure at the surface will move east across the
Ohio Valley with an inverted surface trough extending north
across the local area Saturday night. Due to the upper level
support and wave of low pressure along with the aid of day time
heating, expecting showers and a few thunderstorms to develop
Saturday and then lingering into Saturday night. A cold front is
expected to move east across the area Sunday afternoon with a
bit of a surge of moisture associated with the front and
convergence along the boundary. This should bring a line of
showers and thunderstorms east across the local area during the
afternoon. Once front shifts east Sunday night, threat for
showers and thunderstorms will diminish Sunday night into Monday
morning. Then, by Monday afternoon, a surface trough and deep
digging negatively tilted upper level trough will move over the
local area. Cold air advection and upper level support will
likely cause some lake induced showers over the northeast.
Temperatures through the period will be in the middle to upper
70s most areas; except lower 80s extreme west Saturday. Lows
Saturday night will be in the lower to middle 60s and highs
Sunday in the middle to upper 70s east and upper 70s to lower
80s elsewhere. Lows Sunday night will be in the lower to middle
60s followed by highs in the middle to upper 70s Monday.

&&

.LONG TERM /MONDAY NIGHT THROUGH THURSDAY/...
Large upper level trough will shift east of the area Monday
night into Tuesday. Another upper level positively tilted trough
will linger behind into Wednesday as an upper level high
pressure over the Plains States continues to amplify and remain
nearly stationary. This whole upper level pattern remains
somewhat unchanged through Thursday but there are some signs the
trough in thee east will make an attempt to break down slightly
over southern Canada and cut-off the trough by the end of the
week. Weak surface high pressure will build southeast over the
eastern Great Lakes during this forecast period and will for the
most part keep the forecast area dry. Temperatures will be in
the middle to upper 50s each night and highs will be in the
middle to upper 70s Tuesday and Wednesday and warming a bit for
Thursday in the upper 70s to lower 80s.

&&

.AVIATION /12Z Friday THROUGH Tuesday/...
VFR flight conditions expected through today. Increasing high clouds
will gradually lower into a mid cloud layer by this afternoon. Some
afternoon convection is expected to develop, but should remain south
and west of the TAF sites, with chances too low to mention at KTOL
and KFDY at this point.

Outlook...Non-VFR with isolated to scattered showers and
thunderstorms tonight through Sunday night.

&&

.MARINE...
Winds on the Lake today will remain northeast, with a large
area of high pressure over western Quebec. Winds are again
expected to increase to near small craft range, with these
winds not decreasing in strength until the second half of
tonight.

Otherwise, light southeast flow develops into the weekend. A
cold front is expected to move east across the area Sunday
afternoon and this will result in some cold air advection to the
area. There is the possibility for some waterspout activity
Monday with the cold air advection. Winds will diminish and
become light north to northwest by Thursday.
