Area Forecast Discussion
National Weather Service Cleveland OH
637 AM EDT Fri Jun 14 2024

.SYNOPSIS...
A cold front will move south across the area Friday morning,
followed by a strong upper level ridge that will persist through
the weekend into next week.

&&

.NEAR TERM /THROUGH SATURDAY/...
630 AM...A cold front is pushing south across the area this
morning, evident on radar and characterized by winds shifting
towards the north. The forecast continues to trend drier across
our southeast, as the remnants of the overnight MCV exits OH.
This feature will likely become the focus for initiation later
today further east with only isolated activity anticipated along
the front.

Unfortunately, this means that much of the region will likely
remain dry once again as the front continues to push south
across the area through today. Depending on the front`s
southward progression throughout today, there could be some
additional thunderstorm development later this afternoon,
mainly along the US-30 corridor, though given recent trends,
confidence appears to be decreasing in this potential and
anticipate PoPs may need to be lowered in the next update as
residual outflow boundaries appear to be much further south and
east. However, if any storms are able to develop later this
afternoon along the front, they will have a narrow and brief
window to become strong to severe with favorable mid- level
shear of 40 to 50 knots in addition to modest MLCAPE of ~1000
J/kg. These storms would primarily pose a wind/hail threat given
straight and long hodographs.

Quiet and more seasonable weather will arrive on Saturday with
highs generally upper 70s to lower 80s. This will likely be the
last "nice" weather day for a while as a prolonged heat wave begins
to develop on Sunday and is expected to persist through much of
next week. More details on that below.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
Upper level high over the southern plains region will migrate
eastward and build over the eastern third of the CONUS for the end
of the week and into early next week. The main story is a building
heat wave over the region that has been in the forecast for a few
days now with temperatures well into the 90s by Monday. Only far NW
PA will potentially remain in the upper 80s, but conversely, on the
western end of the CWA upper 90s should be expected. The
ground/surface continues to dry out overall despite a little rain
yesterday in NW OH which will contribute to the ability of the
temperatures to climb. Will need to see if there will be any cloud
cover, but likely just some cumulus fields for the CWA. The
operational long terms differ a little bit with one having lower
500mb heights and 850mb temperatures, and also suggesting convection
possible with enough layer moisture while the other has a stronger
dome of high pressure aloft and less convective coverage in the
return flow setup. Leaning towards the hotter and drier solution for
this forecast into Monday. Immediate lakeshore areas may be a couple
degrees cooler Monday, but the southerly wind component will likely
eliminate much of that advantage. Dewpoints mainly in the mid 60s to
lower 70s.

&&

.LONG TERM /TUESDAY THROUGH THURSDAY/...
Heat wave will continue into the long term portion of the forecast
towards the end of next week. No real changes to the pattern
overall. The upper level high will likely shift towards the
northeastern US, but this will not change the sensible weather much
for our CWA. Expect 90s to be the norm through the week and very
little in the way of rain chances with no organized systems moving
into the region with the largely blocked upper level pattern. Will
be needing rain by the end of the long term forecast as it stands
with this issuance. Dewpoints persist in the mid 60s to lower 70s
through the period.

&&

.AVIATION /12Z Friday THROUGH Tuesday/...
VFR across the TAF sites this morning with primarily VFR to
persist through the TAF period. Isolated to scattered
thunderstorms may develop along the US-30 corridor this
afternoon, primarily impacting CAK, though confidence remains
low. Will maintain a brief window of vcts at this time. There
could be a narrow corridor of MVFR ceilings ahead of an
approaching cold front this morning, but confidence on coverage
remains low.

Winds are variable this morning, favoring a northerly direction
behind the cold front and remaining out of the southwest ahead
of the front. Eventually, all winds will be out of the north by
later this afternoon behind the cold front, around 10 knots.

Outlook...Primarily VFR expected through Tuesday.

&&

.MARINE...
With a cold front coming through, onshore winds prevail today
through tonight 15-20kts for the central and western basins of Lake
Erie with 1-3ft wave heights, becoming 10-15kts Saturday with a more
easterly component to the winds and waves gradually subsiding to the
1-2ft range. From Sunday on, expect offshore winds to prevail with
high pressure situated to the east of the region and nearshore wave
heights generally a foot or less through the rest of the forecast
period.
