337 pm edt Fri jul 19 2019

Synopsis
A ridge of high pressure will build northeast over the eastern
united states and linger through Saturday night. A cold front
will move south across the area Sunday. High pressure will build
east out of the middle mississippi valley region Tuesday to the
ohio valley by Wednesday with below average temperatures.

Near term through Saturday night
Lower confidence forecast this evening with respect to
convective potential. A few subtle disturbances will pass just
north of the area this evening. Convection already firing ahead
of these features has prompted a severe thunderstorm watch for
portions of the area. A highly unstable environment has
developed over the area, with SBCAPE values near 5000 j kg, and
increasing low and good mid level lapse rates. Shear will remain
marginal through the night, with effective bulk shear values
around 25 kts. The main threat for severe weather will be
damaging wind gusts. Hi-res guidance is not handling the finer
details very will, especially with the ongoing convection, but
currently thinking the best threat for storms will peak around
00z across the area. Thunderstorm chances will decrease through
the overnight as the atmosphere stabilizes and the main forcing
mechanisms depart the region.

The story for tomorrow is the continued heat and humidity. Not
much changes with the forecast, with highs in the low to mid 90s
and resultant heat indices peaking in the 105f-110f range. Have
kept the headlines the same for now, but the highest heat
indices will again be west of the i-71 corridor on Saturday.

Precip chances will increase again Saturday evening, as the
pattern hints at upstream convection tracking into the area.

With details fuzzy this far out, kept pops in the chance range,
mainly across the northern part of the area, tomorrow evening
and night.

Short term Sunday through Tuesday night
The cold front will be crossing the lake early Sunday and it
will slow as it proceeds into northern oh NW pa. Will continue
with the likely shower thunderstorm wording, but timing of the
front will need to be watched. Peak heating timing may give us
an opportunity for stronger storms. But with the front lingering
a bit longer, it will still be warm and muggy Sunday and precip
chances will drag into Monday, especially for the southern half
of the area. High pressure will build across the great lakes
Monday into Tuesday with a weak trough crossing the eastern
lakes Tuesday. Tuesday is dry with the outside chance of a
shower across the snowbelt. Temperatures for the early part of
the work week will be much more comfortable and we will return
to highs in the upper 70s lower 80s.

Long term Wednesday through Friday
We will retain some semblance of an upper trough through the
rest of the work week and with that seasonable temperatures that
will climb a degree or two each day. Generally left the long
term dry although cannot rule out a spotty shower with the
presence of the upper trough. No significant features to target
better precip chances on.

Aviation 18z Friday through Wednesday
MVFR ceilings are holding strong across the area under a humid
ridge. Some of the ceiling may mix scatter out, but cloud bases
will be near or just belowVFR for through this evening.

Thunderstorm potential will arrive later this afternoon evening
across portions of the area. Have mentioned thunder chances in
tempo groups at kcle, kyng and keri given the latest radar and
model trends. Quiet conditions overnight may lead to some
redevelopment of MVFR possible ifr ceilings at southeast
terminals. Winds will generally remain southwesterly through the
period, with some gusts to 20 kts or so through the rest of the
afternoon.

Outlook... Non-vfr possible in showers and thunderstorms Saturday
night through Monday.

Marine
A complex or two of storms are expected to cross the lake this
evening and tonight with a brief disturbance of the general
southwest flow that will continue into and through Saturday. Waves
on the east end for the rest of this afternoon and for Saturday
afternoon will be 3 feet with an occasional 4 footer. Wind waves
higher in storms. Storms are also possible again on the lake
Saturday with the main forcing Saturday night with a cold front
nearing the lake. Cold frontal timing is sometime Sunday morning
with the front slowing as it pushes south of the lake. Winds on the
backside of the front will shift to the north for Monday into
Tuesday although a secondary trough will cross the eastern lakes
Tuesday. Going into mid week high pressure is weakly in place across
the lower lakes and ohio valley.
