area forecast discussion
national weather service cleveland oh
951 am edt Tue aug 20 2019

Synopsis
A stationary front will lift back north across the area as warm
front this morning. A cold front will move southeast across the
local area Wednesday evening. A ridge of high pressure will
build southeast across the area Thursday. High pressure will be
centered over the local area Friday night. Below average
temperatures are expected for the end of the week and weekend.

Near term through Wednesday
No major changes to the forecast with the mid morning update,
aside from some minor adjustments to pops and sky cover over the
next several hours. Still expecting scattered convection to
impact parts of the area generally around and after 22z.

Original discussion...

the main show we will be tracking for today is the evolution of
a strong MCS developing across iowa this morning and tracking
towards the east-southeast. We are seeing fair skies and quiet
weather across northern ohio and northwest pennsylvania this
morning. There could some some patchy fog in lower elevations
and valleys this morning. Otherwise, we are rain and storm free
at this morning.

The region remains in a westerly flow aloft and an upper level
high pressure system down closer to texas. A stronger shortwave
impulse is currently moving across the midwest this morning near
iowa. There is severe convection already out there this morning
and starting to organize into what will be a MCS moving through
the midwest and into the ohio river valley later today. Short
term and high-res models are in fair agreement and timing of the
mcs moving into western ohio by 20z-21z. The question remains
if most of the energy of the MCS dives southeast across southern
ohio late this afternoon or has a more eastward push across
central and maybe portions of northern ohio between 21z and 00z
this afternoon. The latest NAM 4km, hrrr, nmm, and arw seem to
think so. The nam12 and other guidance seem to move the complex
more towards the southeast down by the ohio river. We will go
with a chance for scattered or a broken line of storms moving
into the area late this afternoon and evening. Some of which
will be strong to severe with damaging wind gusts up to 70 mph
possible and large hail up to quarter size. It will be quite
warm and humid again this afternoon with highs in the middle to
upper 80s and dewpoints in the low 70s. These conditions will
add fuel to these potential severe storms. Convection with this
complex may linger through 03z this evening before moving out
and weakening.

We will start to see the weather pattern shift with the upper
levels. A cold front will start to gain momentum from southern
ontario and the upper great lakes region and push southward by
Wednesday afternoon. Additional scattered showers and storms
will be possible as the front moves through. The better dynamics
for stronger convection will be east of our area on Wednesday.

Short term Wednesday night through Friday night
Through the course of the short term, a trough from the upper
midwest northern lakes will rotate across the great lakes. High
pressure at the surface will slowly build through the second half of
the week. A cold front may still be across the area early Wednesday
night, but will get shunted south through Thursday. Will continue
the chance pops with this front and have a dry forecast for Thursday
night through Friday night. The front may slow with some lagging
upper energy and those precip chances for Wed night Thursday may
need to be raised if a trend in this direction takes place.

Temperatures will be cooling with lower mid 70s expected
Thursday Friday. Will have a couple nights in the 50s.

Long term Saturday through Monday
Little change with the long term forecast. The high builds across
the great lakes through the weekend and shifts to new england for
early next work week. This will yield a dry forecast with slightly
cooler temperatures (70s) for the weekend and gaining a few degrees
for Monday. Shower thunderstorm chances may creep back into the area
Monday as return flow ramps up and a trough approaches the region
from the west, but for now have kept pops in the slight chance
range.

Aviation 12z Tuesday through Saturday
Vfr conditions should be the rule of thumb for TAF sites across
the area through the next 24 to 30 hours. Skies will generally
be fair today and tonight. There is a slight chance for a few
isolated to scattered storms late this afternoon and evening.

Coverage appears scattered at this point, so will prob30 window
to give the best guess for timing. Winds will be light and
variable 5 knots or less becoming southerly or southwesterly
around 5 knots. Winds will likely be gusty and erratic around
any convection that does develop late this afternoon and
evening. A few strong to severe storms could be possible.

Outlook... Intervals of non-vfr possible primarily with
thunderstorms possible Tuesday night through Wednesday.

Marine
Light winds and an afternoon onshore component will result from weak
high pressure over the lake today. Low pressure crossing the central
lakes will take a warm front across the lake tonight and swing a
cold front across late Wednesday. South-southwest winds will hold
for tonight and Wednesday. With the cold frontal passage and high
pressure building across the central lakes winds will shift to a
northerly direction for Wednesday night and Thursday. The high
expands across the lakes going toward the weekend keeping a north
through northeast flow on the lake through Saturday.
