Synopsis
High pressure over the eastern great lakes this evening will
move off to the east as a warm front pushes north across the
area overnight. A cold front will move south across the area on
Sunday and will then return back north on Monday as a warm
front. Low pressure will move through the central great lakes on
Tuesday into Wednesday and force a cold front across the area
on Wednesday night.

Near term through Saturday night
Latest radar and satellite data show nice circulation moving
east across southern lake huron at this time in response to
upper level positive vorticity maximum. This feature and
associated positive vorticity advection (pva) and moisture have
been producing some scattered shower activity across the area
albeit very light. The best PVA appears to be pushing east at
this time and therefore the resultant showers appear to be
weakening to the west as well. Negative vorticity advection will
begin to push east during the rest of the evening and this
should help suppress any more showers for a period of time.

Surface high pressure over the area at this time will continue
to push east this evening and this will allow warm front just
to the south of the area to push north tonight. Surface analysis
shows warmer air beginning to push north into lima,ohio and will
continue to move north into western portions of the forecast
area over the next few hours. Dewpoints are also beginning to
increase in this area. This trend will occur over the rest of
the area this evening and overnight. Temperatures may dip a few
degrees this evening and then begin to warm up through the night
if clouds stay in and push of warm air is faster than models
suggest. Will monitor this trend over next few hours.

Previous discussion...

while high pressure and an upper ridge reside over the region
this afternoon, some moisture moving over the top of the ridge
is allowing for a couple scattered rain showers to impact some
of the lakeshore areas. These showers should wane later this
evening as the ridge axis crosses over the region. Later
tonight, the warm front lifts north over the forecast area and
could be the focus for some rain development over the same areas
after midnight tonight. With the warm front lifting north across
the area, expect a non-diurnal temperature trend and low
temperatures will be achieved early in the night with increasing
temperatures behind the front.

Saturday presents an interesting weather day over the region.

With the warm front north of the area, temperatures will surge
into the 80s. Good mixing behind the front with the warm
air advection will allow for breezy conditions with wind gusts
to 25-30 mph in the warm sector. With the warm conditions in
place, some diurnal convection may be expected during the late
morning and early afternoon hours. While weakly forced, up to
2000 j kg of CAPE will be in place over the region at this time
and some stronger storms may be possible. Later Saturday
evening, another round of convection remains likely more in line
with a trough moving north of the area and lift in association
with the right entrance region of the upper jet. This round of
convection appears to be better supported dynamically than the
first, but the question remains on if the area will be worked
over from any earlier showers and thunderstorms. Generally
speaking, it appears that showers and thunderstorms should be
expected tomorrow and the severe threat remains conditional and
something to watch going forward.

Short term Sunday through Monday night
Models indicate the frontal boundary will start off overhead on
Sunday before shifting south of the area during the afternoon. The
initial location of the front on Sunday morning will be somewhat
dependent on convection the night before. Shortwave energy will
round the ridge aloft on Sunday, with showers and thunderstorms
developing overhead. The 12z 24 NAM is an outlier with a compact
wave riding along the front across central ohio but suspect this
solution is overdone. However, lots of moisture will remain with pw
values near 1.6 inches and dewpoints in the upper 60s to near 70
degrees so expecting good coverage of showers and thunderstorms
during the afternoon. Instability may be a limiting factor given the
cloud cover but 40-50 knots of bulk shear ahead of the shortwave
moving through the flow aloft so will need to keep an eye on any
thunderstorms that develop. There is a marginal risk of severe
thunderstorms focused south of route 30.

The boundary settles south Sunday night as high pressure builds east
across the great lakes. Marginal rises in water levels can be
expected along the west half of lake erie with easterly winds of 10-
15 knots. The warm front will lift back north on Monday with a
chance of showers or thunderstorms along the warm front Monday
afternoon and lifting northeast across the area Monday night. This
should leave the area primarily in the warm sector on Tuesday with
breezy southwest winds and temperatures in the 80s.

Long term Tuesday through Friday
The second half of the week will start off warm before the ridge
breaks down with temperatures settling back closer to normal by
Friday. Low pressure will track across the upper great lakes towards
james bay on Wednesday with upper level energy spilling around the
ridge and likely kicking off convection across the area. The initial
cold front will follow on Wednesday night but a stronger push of
cold advection does not arrive until later Thursday. High pressure
will build in by Friday bringing near seasonal temperatures and dry
conditions.

Aviation 18z Friday through Wednesday
High pressure over the eastern great lakes region will allow for
vfr conditions to continue through the afternoon and evening
hours. A mid-level deck of clouds has overtaken the region this
afternoon as the remnants of some showers and storms earlier
this morning in indiana. A warm front lies to the south of the
area and will slowly lift north this evening and pass north of
the area overnight. Ahead of the front, some scattered showers
may develop, but the airmass remains fairly dry, so coverage
will be fairly limited and will omit from the tafs. Behind the
front, winds will shift around to the south and become fairly
breezy as there will be some good mixing and ceilings should be
scattered in the warm sector. Showers and thunderstorms are
expected in the region on Saturday afternoon and evening and
have begun a vicinity thunder mention at kcle for the end of the
30 hour TAF period.

Outlook... Non-vfr possible in thunderstorms Saturday and Sunday.

Marine
A period of unsettled conditions is expected over the weekend as a
frontal boundary wobbles north and south across the lake bringing
several rounds of thunderstorms. Onshore winds this evening will
shift to the south on Saturday as a warm front lifts north across
lake erie. Southerly winds will shift to the southwest or west by
evening with a window of choppy conditions and 2 to 4 foot waves
east of cleveland. Winds or waves could be enhanced by thunderstorm
activity moving south out of canada. A cold front will settle south
on Sunday with northwest winds of 10 knots or less veering to
northeast Sunday night. Easterly winds of 10-15 knots on Monday
morning will result in minor rises in water level on the western
basin of lake erie before another warm front lifts across the lake
with winds shifting to southwesterly. Breezy southwest winds are
expected Tuesday into Wednesday.
