12z aviation forecast update...

Synopsis
A zonal flow will set up across the great lakes region this
weekend through the early part of next week which will bring an
active weather pattern as well as above average temperatures. A
trough will cross the great lakes region towards the middle of
next week bringing a cooler and drier airmass to the region for
the end of the week.

Near term through Sunday
The main challenge and concern will be the timing and threat for
additional thunderstorms this weekend, mainly during the
afternoon and evening. There is currently some very active
weather and storms ongoing across the central u.S. Associated
with a stout MCV near kansas city. This system will be racing
eastward with a fast zonal flow. Timing and placement are
slightly different amongst the various high-res models and
guidance. But the general consensus will be this MCV nearing
western ohio by 21z and crossing through northern or central
ohio during this evening. With this feature in the region during
the late afternoon and evening along with bulk shear values
approaching 35 knots or so, we will have to monitor the threat
for additional thunderstorms with a few strong to severe. The
main threat will be damaging wind gusts up to 65 mph and large
hail up to quarter size.

It appears the weather and storms may calm down after midnight
through early Sunday morning. There will be another series of
mcvs riding along the mid level flow but timing will be hard
more than 24 hours out. One MCV may reach far northwest ohio by
12z Sunday morning with another round of possible storms for
that part of ohio and the western basin of lake erie. The mcv
depicted by the models which appears to move across northern
indiana towards lake erie by 21z may be the one to watch more
closely due to it coming across during peak daytime heating and
a little better thermodynamics. The main story for tomorrow will
be again the chance for additional storms in the afternoon with
a few severe possible. Temperatures will be running warmer than
average, in the middle and upper 80s with humid conditions.

Short term Sunday night through Tuesday night
Instability will linger into the Sunday overnight hours, allowing
scattered showers and thunderstorms to persist. A cold front will
approach from the northwest Monday morning and slow down into a weak
west-east oriented stationary front over our forecast area. Although
there is weak upper level forcing, MUCAPE ranging between 2000-3000
j kg will be plenty to support mostly diurnally driven showers and
thunderstorms, some of which could produce strong downburst winds
and some hail on Monday and Tuesday. There won't be too much
vertical wind shear each of these days, so there won't be much
organized convection and any threat of severe weather will remain
isolated. Flooding could be a concern with a weak stationary front
over our area. Pwat is expected to range between 1.6 and 1.8 with
mean storm motions around 15 to 20 knots. While these numbers aren't
particularly concerning, the presence of a stationary front along
with this environment could prove problematic if we get training
thunderstorms.

Long term Wednesday through Friday
A large digging upper trough is expected to move southeast across
ontario and into the upper great lakes region Wednesday. A surface
low is expected to develop over ontario and into western quebec. A
cold front extending from the low is expected to sweep through our
forecast area on Wednesday afternoon. A relatively warm, moist
atmosphere will still be in place ahead of this front. With slightly
higher deep layer shear of 25 to 30 knots present on Wednesday,
convection that initiates along and ahead of this cold front should
be more organized that Monday and Tuesday's convection. The threat
for severe weather will be a little bit higher on this day is the
passage of the cold front is during the afternoon when it is most
diurnally favorable. High pressure will follow on Thursday and
Friday, with a big airmass change. Expect mostly sunny skies,
temperatures in the mid to upper 70s and dew points in the upper 50s
on Thursday and Friday, all of which are far more comfortable than
the preceding days.

Aviation 12z Saturday through Wednesday
GenerallyVFR conditions are expected through the next 24 to 30
hours with the exception around convection and scattered
showers where brief MVFR to ifr could be possible. There may be
some vcts between 18z and 21z but not confident enough to
mention in tafs at this point. Have targeted the best potential
for scattered afternoon and evening convection to possibly
impact TAF sites between 21z and 24z in prob30 groups. There is
a very limited chance for a couple strong to severe storms as
well across the region this afternoon and evening. Otherwise,
winds will be generally 5 to 11 knots from the south or
southwest during the next 24 hours.

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

Marine
Generally west to southwest flow will persist through the weekend. A
west to east oriented stationary front is expected to be present
over or south of the lake on Monday and Tuesday, making winds and
waves a little more variable on those days. Scattered thunderstorms
remain in the forecast through Wednesday. A cold front will move
east across the area Wednesday afternoon. Northerly winds of 10 to
15 knots will follow this, bringing waves of 2 to 4 feet,
likely to be the highest waves in the forecast period.
