area forecast discussion
national weather service cleveland oh
1007 am edt Thu jul 18 2019

Synopsis
High pressure will ridge northward from the southeastern united
states today then remain nearly stationary through Saturday. A
cold front will slide southeast across the region Saturday night
with a reinforcing surge of cooler air arriving Sunday night. High
pressure will build south toward the area early next week.

Near term through Friday
A line of showers and thunderstorms will continue to move
southeast into indiana this morning and early afternoon. Latest
spc model guidance suggests some destabilization will take place
as heating increases through the morning ahead of the line. The
bulk of the heavier activity may just give us a glancing blow as
things look now. However, will introduce a chance for showers
and thunderstorms in the western portions of the forecast area
for today. Expecting activity to reach toledo and findlay areas
after about 20z this afternoon. Otherwise, rest of the area
should remain dry and hot. No other changes to the rest of the
forecast area.

Previous discussion...

increasing heat remains the main story for this forecast. All
locations will warm today with NW ohio being the hottest.

Western areas will only hit heat advisory levels (heat indices
100-104) today but the cumulative impacts of the heat will begin
this afternoon and continue into Saturday. The elevated
afternoon heat indices will reach into the heat warning
criteria (greater than 105) on Friday and Saturday with a few
locations seeing 110 or higher for a few hours across the west.

So these high heat indices combined with lows above 75 degrees
will cause a cumulative impact on the region through Saturday.

This is the reason we hoisted the warning for NW ohio starting
today.

It will be very warm to hot elsewhere today but the extreme heat
likely wont arrive until Friday into Saturday. So we will
continue with the excessive heat watch for now. There is some
uncertainty about the highest heat index values across the
region with convective debris cloudiness moving over the region
from the west. There are also some low chances that some thunder
could move into NW ohio or maybe even across lake erie into nw
pa early Friday morning. Outflow from this convection combined
with a lake boundary that will be along the lakeshore from lake
county to erie county, pa may generate enough low level
convergence to produce isolated scattered thunderstorms. Did
not go widespread with the thunderstorm chances since 5h
heights are at least 591 dm across the region. This typically
greatly reduces the convective coverage and may be enough to
keep it from developing. If thunderstorms can develop they will
have the potential to produce strong winds and maybe some small
hail, especially on Friday across NW pa.

Short term Friday night through Sunday night
The upper level ridge and heat wave will be in full force going into
Saturday. The center of the heat wave will be over the ohio river
valley region. Overnight low temperatures Friday night into Saturday
morning will be near record high minimums for the date. Some
locations will remain in the upper 70s to near 80 for overnight low
temperatures, especially around urban areas. A frontal boundary will
start drifting southward across the upper great lakes region on
Saturday. We may see a few more clouds and a slight chance for a
shower or storm along our northern areas. But only a lucky few may
see a cooling spot rain shower. The main story will still be the
dangerous heat wave Saturday. Afternoon temperatures will top out in
the middle 90s again with heat indices between 100 to 110.

The ridge starts to break down Saturday night into Sunday. We will
see that frontal boundary make progress moving southward. Widespread
showers and storms are likely Sunday into Sunday night. Temperatures
will still be warm ahead of the front but more typical warmth. We
will have to keep an eye out for a few stronger to severe storms
possible Sunday afternoon and evening.

Long term Monday through Wednesday
A big weather pattern change is heading our way for the early and
middle of next week. A big amplified weather pattern sets up with a
large ridge in the western u.S. And a deep trough develops over the
great lakes region. We will see a refreshing northerly flow with
cooler and drier weather coming down from canada. Some clouds and a
few showers may still be around early on Monday before the drier
airmass moves in. We will see dewpoints drop into the lower 50s and
be very comfortable. Overnight low temperatures will be in the 50s
to around 60. Afternoon high temperatures will be in the middle 70s
to lower 80s. We will be able to give the a.C. A break and open the
windows!

Aviation 12z Thursday through Monday
Areas of MVFR ifr fog will cause issues until just after sunrise.

Most of the issues will be for kcak and kyng, but MVFR fog will
be possible elsewhere. Otherwise it appears there will be periods
of convective debris cloudiness from the west with some afternoon
cumulus mixed in with it. Any thunderstorms should remain across
central indiana and across michigan this afternoon.

Winds will be rather light today. Lake breeze will likely impact
keri and may attempt to reach kcle.

Outlook... Non-vfr possible in showers and thunderstorms
Friday and again Saturday night through Sunday night.

Marine
Weak high pressure over the lake this morning is giving us light and
variable winds. Southerly winds 5 to 10 knots will return later today
and tonight. Southwesterly winds 10 to 20 knots will be over the
lake on Friday and we may get close to a small craft advisory due to
wind speeds. Southwesterly winds 10 to 15 knots will continue into
Saturday ahead of an advancing cold front. Winds on Sunday may be
somewhat erratic and changing with a frontal boundary slowly moving
across the lake as well as interacting surface boundaries from
convection. A stronger high pressure system moves in for Monday
through early next week with a northerly flow over the lake 10 to 20
knots. We may see a day or two early next week with small craft
advisory conditions with higher wind speeds and higher waves near
the north facing lakeshore.

Climate
It will be hot over the next 3 days but most of the records
will be tough to reach. Here is a list of the record highs
and the warmest minimum temperature today through Saturday.
