Area Forecast Discussion
National Weather Service Cleveland OH
122 AM EDT Sat Jun 15 2024

.SYNOPSIS...
High pressure will build across the region tonight and persist
through the weekend. A strong ridge will remain over the region
through much of next week providing well above normal
temperatures.

&&

.NEAR TERM /THROUGH TODAY/...
No changes to the forecast at this time.

7 PM Update...
The cold front has cleared through the forecast area and any
shower/storm threat is done for the night. Some orphaned mid-
level clouds remain in NW Ohio and close to the front, but
conditions will trend to clear with the loss of diurnal heating.
Light north to northeast winds will be favored through Saturday.

Most of Previous Discussion...
High pressure builds into the area tonight and persists through
Saturday night, with mainly clear skies and seasonable
temperatures. Highs Saturday will be in the mid 70s to low 80s
across the area, with areas near Lake Erie only reaching the low
70s. Lows tonight and Saturday night will generally be in the
50s.

&&

.SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/...
An dominant ridging pattern is expected through the short term
period, with the axis of the ridge moving over the region Sunday
afternoon into Sunday night. This ridge coupled with the associated
surface high and dry airmass will keep conditions dry Sunday and
Monday. The one thing to watch on Monday is a shortwave upper level
vort max that pushes along the northern fringe of the ridge which
will be located near Lake Erie. This may result in some isolated
showers/thunderstorms over and/or near Lake Erie, but confidence is
higher north of the entire area, so opted to maintain dry conditions
for now. Both days can expect a diurnal cu field to develop, which
will give a few breaks in the direct sun, but with increased WAA and
very dry surface antecedent conditions, expecting temperatures to
begin to climb. On Sunday, highs will be in the mid 80s to low 90s
before climbing into the 90s for the entire area Monday. The
exception will be the far western tier of counties which may touch
100 degrees on Monday. In addition, higher dewpoint values ranging
from the mid 60s to low 70s will result in apparent temperatures
values exceeding 100 for areas along and west of I77. Not much
relief will be felt with overnight temperatures only falling into
the upper 60s to low 70s both nights. This period ultimately marks
the start to a prolonged period of well above normal temperatures.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
The dominant ridging pattern discussed in the short term period is
expected to persist through much of the long term period. Near the
end of the period on Friday, the upper level ridge axis is expected
to shift to near the East Coast along with the surface high. This
means that the aforementioned prolonged well above normal
temperatures will likely continue through Thursday and Friday with
highs in the 90s, lows in the 70s, and heat indices nearing 100.
With such a prolonged heat wave, there are the potential for heat
related illnesses, especially for the vulnerable populations and
those that do not have places to cool down. Stay tuned for updated
forecasts, especially about when the area will see some relief.

&&

.AVIATION /06Z Saturday THROUGH Wednesday/...
VFR across the TAF sites early this morning with VFR to persist
through the TAF period. No precipitation is anticipated through
the TAF period.

Winds are generally out of the north early this morning, 5 to 8
knots. Winds will generally favor a northerly direction through
much of today. Winds will gradually favor a more northeasterly
direction by later this evening and overnight.

Outlook...Primarily VFR expected through Wednesday. An isolated
thunderstorm or two is possible in the afternoon on Monday and
Tuesday, though confidence is low.

&&

.MARINE...
High pressure has begun to build over the area and will persist
through much of next week, slowly meandering towards the East Coast.
Winds tonight will be from the north-northeast at 10-15 knots,
weakening on Saturday to 5-10 knots. This will result in waves of 1-
2 feet, especially in the central basin. On Sunday, winds of 5-10
knots become southeasterly allowing for waves less than 1 foot. The
winds shift again on Monday to become southwesterly but remain at 5-
10 knots as the high pressure is dominant. Winds will generally
maintain a southerly component through the end of the week with
little change expected in the overall pattern. No marine headlines
are expected at this time.
