Area Forecast Discussion
National Weather Service Cleveland OH
732 PM EDT Sun Jul 23 2023

.SYNOPSIS...
An upper trough moves across the area this evening before
surface high pressure builds into the area overnight. Surface
high pressure lingers over the region through the week with a
few shortwave troughs moving overhead.

&&

.NEAR TERM /THROUGH MONDAY NIGHT/...
Water vapor imagery continues to show a short wave moving
southeast into NW OH as of 00Z. This area of vorticity has
assisted afternoon heating and outflow boundary interactions to
get some briefly stronger storms to develop. Mostly just 40 mph
and half inch hail. However a couple storms across Morrow and
Knox counties were strong enough to warrant warnings earlier
this evening.

Any stronger convection will be located near and east of I-71
through sunset. Elsewhere showers and a couple thunderstorms may
redevelop ahead of the southeastward moving short wave.

Previous Discussion...
Scattered convection continues to persist across the region,
mainly across northwest Ohio and along the Lake Erie shore in
northeast Ohio. Some of the cells over the past two hours have
pulsed up to appreciable levels to produce some gusty winds and
perhaps some hail. Around 1000 j/kg MLCAPE currently present
across the area with steep low level lapse rates allowing for
quick developing/short duration convection. Overall, storms are
not expected to be strong to severe given the lack of deep layer
bulk shear marginal mid level lapse rates. Coverage should
expand a bit eastward over the next several hours as an upper
shortwave works east towards the lower Great Lakes. Instability
is expected to weaken diurnally this evening and would expect
shower/storm coverage to diminish aside from some lingering
shower activity coincident with the vort max moving over the
region tonight.

Broad upper troughing will remain over the region tonight
through Monday night with some weak surface high pressure
building into the area. Some diurnally driven convection
possible on Monday, but the better support for convection may
remain south of the area. Went with slight chance/low chance
pops similar to the previous forecast.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...
Cyclonic W'erly to NW'erly mid/upper-level flow and embedded
shortwave disturbances are expected to impact our CWA during this
period. At the surface, we should be located along the northern
flank of a high pressure ridge centered in vicinity of the southern
Appalachians. Simultaneously, multiple and subtle surface trough
axes should accompany the shortwave disturbances and traverse our
region generally from west to east. Net low-level warm and moist air
advection from the Gulf of Mexico will contribute to a warming trend
in our CWA as humidity increases. Sufficient daytime heating of
surrounding land and a relatively-weak synoptic MSLP gradient should
allow a lake breeze to occur within about five miles of all of Lake
Erie during the late morning through early evening hours on Tuesday
and within about five miles of the lake from northeastern Cuyahoga
County to Erie County, PA during the late morning through early
evening on Wednesday. Overnight lows should reach mainly the 60's
around daybreak Wednesday morning and mainly the mid 60's to lower
70's around daybreak Thursday morning. Late afternoon highs should
reach the 80's to 90F on Tuesday and the mid 80's to lower 90's on
Wednesday. The coolest highs are expected within the lake breeze. Of
note, normal lows are in the lower to mid 60's and normal highs are
in the lower to mid 80's this time of year. Isolated to scattered
and periodic rain showers/thunderstorms are possible, especially
during the afternoon through early evening hours of the short-term
period, since daytime heating of the humid boundary layer should
yield moderate to perhaps strong CAPE and non-excessive CIN for
parcels rooted in that layer. Low-level convergence and associated
ascent along the expected lake breeze front and surface trough axes
should act as a focus for shower/storm formation. However, odds
favor fair weather on Tuesday when the stabilizing surface ridge may
exert greater influence in our CWA.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
W'erly to NW'erly mid/upper-level flow is expected to remain
cyclonic over our CWA during the long-term period. Additional
shortwave disturbances embedded in the flow aloft are forecast to
impact our region. At the surface, a high pressure ridge is expected
to remain centered near the southern Appalachians and influence our
region before a cold front drifts SE'ward across our CWA on Friday
and/or Saturday. Another high pressure ridge should build from the
Canadian Prairies and north-central United States behind the front.
However, subtle surface trough axes accompanying the shortwave
disturbances will continue to move generally E'ward through our
region. Periodic and isolated to scattered showers/thunderstorms
remain possible amidst sufficient atmospheric moisture and
instability, especially on Friday into Saturday with the approach
and eventual passage of the cold front. Continued low-level warm and
moist air advection ahead of the cold front will contribute to
unusual warmth and continued increase in humidity on Thursday
through Friday. Late afternoon highs are forecast to reach mainly
the lower to mid 90's on both days. Overnight lows should reach only
the lower to mid 70's in most locations around daybreak Friday
morning. Somewhat cooler readings are expected Friday night through
Sunday due to low-level CAA behind the eventual cold front passage,
fairly abundant cloud cover, and the wet-bulb effect associated with
periodic precip. Overnight lows should reach mainly the 60's around
daybreak on Saturday and Sunday mornings. Daily highs should reach
mainly the upper 70's to mid 80's this upcoming weekend.

&&

.AVIATION /00Z Monday THROUGH Friday/...
Areas of showers and thunderstorms will continue across the
region, mainly near and east of I-71. MVFR/IFR conditions are
expected around any of the showers and thunderstorms. All of
this activity should dissipate shortly after midnight, lingering
longest near the OH/PA border into NW PA.

VFR conditions should occur late tonight through late Monday
morning. Isolated to scattered convection develops again Monday
afternoon. Current thinking is that most of the convection
develops along the lake breeze boundary across NE OH into NW PA
and near and south of a line from KTOL to KMFD to Millersburg.

Light winds away from the thunderstorms. Thunderstorms may
produce speeds up to 35 knots through sunset. Southwest to west
winds of 5 to 12 knots should after sunrise Monday. Lake breeze
boundary turns winds off of the lake at around 12 knots Monday
afternoon.

Outlook...Non-VFR in isolated to scattered afternoon/evening
showers and thunderstorms Tuesday through Thursday. The greatest
chance of thunderstorms appears to be Tuesday evening into the
overnight.

&&

.MARINE...
Primarily southerly to southwesterly winds around 5 to 15 knots are
expected through Friday as a ridge lingers over Lake Erie and the
parent high pressure center moves from near the Lower MS Valley
toward the southern Appalachians. However, a daily lake breeze
should impact all nearshore zones during the late morning through
early evening hours on Monday and Tuesday, and nearshore zones from
roughly Cleveland to Ripley on Wednesday. Waves trend mainly 3 feet
or less. Occasional 4 footers are possible on Friday when
predominantly southwesterly winds may freshen toward 20 knots and a
cold front approaches the lake from the northwest.
