key message 1...
upper level ridging over the plains region that has been persistent
over the past several days will work its way eastward into the great
lakes heading towards midweek. high pressure that had been building
into the southern great lakes from the north will finally trudge
eastward after keeping the region in northeasterly flow this
weekend. this will allow flow to finally turn southeasterly by
tuesday, and then as the cold front approaches from the west,
southwesterly with surface dewpoint advection, all while 500mb
heights increase. though the weather will be dry prior to wednesday,
expect a brief period of very warm/humid air in the region late
tuesday into wednesday prior to the arrival of convection/the cold
front as temperatures and dewpoints climb.

key message 2...
will see low level jet, shear, and mlcape values increasing
ahead of the cold front for wednesday into wednesday night
leading to higher confidence of thunderstorms for the midweek
period. one thing to watch will be the track of the main surface
low for this system as it currently looks to push through
northern ontario/james bay/northern quebec with the upper level
trough as well. with the main energy that far north, will need
to watch how the models handle the placement of the aforementioned
low level jet. as it stands, the stronger winds should be further
to the northeast towards upstate new york/new england. so at this
point, still have many of the finer details to sort out for this
system, but for now, it looks like lines of storms ahead of the
cold front should be expected with at least a potential for
severe weather for now.

.aviation /06z monday through friday/...
vfr across the taf sites early this morning with vfr to persist
through the taf period. a sct deck around 3.5kft may develop
this afternoon across the interior with brief pockets of bkn
possible. otherwise, winds will favor an east to northeast
direction through the taf period, generally 7 to 10 knots.

outlook...non-vfr possible in showers and thunderstorms
wednesday into thursday.

&&

.marine...
one last day of persistent northeast winds 10-20kts that will
bring wave heights 2-3ft over the central and western basins of
lake erie, peaking in the late afternoon hours today. surface
winds finally turn offshore/southeasterly tonight 5-10kts into
tuesday with wave heights in the nearshore a foot or less.
winds turn west southwesterly 15-25kts heading into wednesday
ahead of a cold front. this will translate to immediate
nearshore zones cleveland and west at 1-3ft waves, increasing
rapidly away from shore. cleveland east towards new york expect
wave heights 3-5ft with the winds now parallel to the shoreline.
a small craft advisory may be needed wednesday into wednesday
night.

high pressure over the eastern great lakes provides a tranquil labor
day. high clouds are spilling in from convection elsewhere in the
midwest, however. this activity is on the decline, so, generally
more sun than clouds today. our pesky upper-level ridge, now
centered over western mn, will exert a hint of influence overhead
today as temperatures creep up a touch warmer than sunday; highs
generally in the low-80s. the ridge tracks east tuesday and
wednesday but flattens through time as low pressure deepens over
manitoba. a trailing cold front moves through wednesday bringing a
40-60% chance of showers and thunderstorms. forecast soundings ahead
of the front wednesday afternoon show marginal support for isoalted
severe thunderstorms. lapse rates are poor, while instability and
shear are both acceptable for early autumn. stray showers may linger
into thursday morning due to the latitudinal orientation of the
occluding front atop southeast us high pressure.

while wednesday looks to be the warmest day of the week, cloud cover
permitting (upper-80s), high pressure over the upper midwest
thursday ushers in upper-70s once again. in the progressive upper-
air pattern the follows, additional chances for rain and storms
arrive next weekend.

status quo with this 12z issuance. high pressure promotes vfr
conditions with fair weather cumulus around this afternoon. wind
generally on either side of 090 today with the slightest hint of
a diurnal trend in speed. with an easterly component to the
wind again early tuesday morning, will have to monitor for any
lake erie induced stratus.

vfr conditions persist today and tonight across the region as high
pressure remains over the region. morning fog was very patchy and
short lived so will start the forecast off with no vsby restrictions
though there may be a short window of shallow ground fog but will
scour out quickly. should have cirrus debris passing over the region
through the day with a possibility of some diurnal cu but should
result in only a few or sct coverage. winds will be easterly today
and southeasterly tonight while remaining light through the
duration.

the continued dominance of low to mid level anticyclonic flow across
lower michigan will provide another dry day across the forecast
area. after a relatively cool morning, daytime heating will again
boost afternoon highs into the upper 70s/near 80. aside from a few
cu, some cirrus may continue to stream into the area from the west.
otherwise, ample sunshine will prevail within the dry ambient
airmass. the mid level anticyclone and associated surface high will
be driven across the eastern great lakes tuesday as an expansive
region of mid level height falls encompass the northern plains and
upper midwest. southerly return flow will advect a slightly warmer
and more humid airmass into southern michigan. model guidance is
strongly supportive of highs into the low 80s tuesday. the moisture
advection may allow some increase in cloud cover during the day
while a strong capping inversion inhibits convection.

the aforementioned height falls will be associated with a
progressive mid level low moving from the canadian high plains
tuesday into northern ontario wednesday. this system will send a
cold front into lower mi wednesday and will flatten the large ridge
across the conus. this will place the great lakes region within
stronger mid/upper level westerlies.

of note within the last few runs of the model suite has been a plume
of deep layer moisture circulating around the large ridge and
advecting into lower mi tues night/wednesday in advance of the cold
front. ecmwf ensemble members indicate precipitable water values
ranging anywhere from 1.8 to 2.2 inches within this moist axis, quite
high for anytime of the year in the michigan. the advection of the
deep layer moisture plume into lower mi tuesday night will warrant a
chance of convection, especially across the northern portions of the
forecast area. conditions will be favorable for upscale convective
growth to the west/southwest of lower mi tuesday night. downstream
propagation of any remnant convection/mcv(s) into lower mi wednesday
will warrant a chance of showers/thunderstorms. residual cloud cover
and precip leads to some uncertainty as to the advection of
instability into se mi wednesday. while the operational nam is quite
bullish on instability, the majority of model solutions and their
ensemble members continue to hint at overall weak instability across
se mi, with the axis of higher daytime instability remaining south of
the state. with the low level frontal boundary and moist axis
aligning more parallel to the mean flow wednesday, even weak
convection may support some prolonged rain and thus locally high rain
totals. more notable short wave energy forecast to traverse the
northern lakes late wed/wed night is forecast to drive the frontal
system into the ohio valley, bringing a little cooler and drier
airmass to forecast area for the later portion of the work week.

marine...

benign marine conditions continue through most of tuesday due to
surface high pressure moving from the central to eastern great
lakes. the next chance for increasing winds and waves arrives
tuesday afternoon, ahead of a seasonably strong low pressure system
tracking across southern canada into hudson bay. robust gulf-
modified southwesterly low-level flow and the associated warm then
cold fronts should lead to rising shower and thunderstorm chances
midweek. pre-frontal winds/waves should peak wednesday afternoon
with the possibility of borderline gusts to gales for portions of
lake huron. drier and cooler conditions are expected for the rest of
the workweek as winds turn northwesterly within a modest pressure
gradient. small craft advisories will likely be needed on wednesday
for at least the lake huron nearshores.
