key message 1...
a strong mid/upper ridge axis will slide over the ohio valley
and great lakes monday as the downstream mid/upper trough
currently over the eastern great lakes slides off the east
coast. this will allow the surface high to drift across new
england and the mid atlantic through the day, setting up
southerly return flow. this warm air advection combined with 850
mb temps warming above 17 c will yield highs in the upper 80s to
low 90s monday, but luckily, dew points will remain fairly
comfortable (a drier heat).

by monday night and tuesday, the first piece of broad overall
western conus mid/upper troughing ejecting across south central
canada will help to pick up a southern stream mid-level
shortwave and eject it through the ohio valley/great lakes. this
will temporarily weaken the mid/upper ridge overhead, and as
the associated surface low lifts through the western and central
great lakes tuesday, a warm front will lift through the region.
this will usher in a much more moist low-level airmass. a few
showers are possible in the isentropic ascent ahead of the warm
front monday night, but surface heating of the increasingly rich
low-level moisture tuesday (dew points rising into the low 70s)
will yield moderate to strong destabilization. this will lead
to widespread convection tuesday afternoon and evening. boundary
layer flow will be weak, and pwats look to climb to near 2
inches, which is near the maximum climatology for june 9, so
slow moving convection with torrential/efficient rainfall will
be a concern. luckily, most of the cwa has had a bone dry past 2
weeks, but training convection will need to be monitored for
localized flooding of low-lying and poor drainage areas,
especially where locally heavy rain occurred yesterday. the bulk
of the area has been placed in a day 3 marginal risk for
excessive rainfall by wpc. temperatures will be a few degrees
lower tuesday due to the clouds and convection, but the much
higher humidity will probably make it feel worse than monday.

key message 2...
the mid/upper ridge will become reestablished across the great
lakes and ohio valley wednesday and thursday while also
expanding across the eastern conus ahead of the main piece of
the western conus mid/upper trough progressing into the northern
plains. deep west-southwest flow and 850 mb temps of 20-22 c
advecting into the region beneath the thermal ridge will allow
for the warmest temperatures of the young summer season.
ensemble guidance points to highs between 88 and 93 f across
most of the area wednesday and thursday, and this combined with
dew points in the low 70s will yield heat indices approaching or
exceeding 100 f in some areas. the nws heatrisk map depicts an
increasing area of major (level 3 of 4) heat impacts wednesday
and thursday, and with this being the first extended period of
heat and humidity of the season, extra precautions will need to
be taken to stay cool and hydrated. overnight low temperatures
will remain elevated in the upper 60s to low 70s.

key message 3...
the hot and humid airmass will allow for scattered diurnal
convection wednesday and thursday, but fairly strong mid-level capping
beneath an elevated mixed layer (eml) plume will keep coverage
much lower than tuesday. nevertheless, if coverage ends up
higher than expected, temperatures and resultant heat indices
could end up a little lower wednesday and thursday. this will
be monitored, but as of now, hot and humid is the main message.

the aforementioned mid/upper trough progressing through the
northern plains is trending faster and looks to reach the great
lakes friday. this will break down the ridge and allow for a
cold frontal passage friday. the trough will bring mid/upper
synoptic support and dynamics, so depending on the timing of the
front, strong to severe thunderstorms are possible friday. lower
temperatures and humidity are expected friday through the
weekend, but still on the somewhat sticky side as the front
becomes quasi-stationary nearby.

thunderstorms early tuesday through thursday.

high pressure will depart to the east by tomorrow. winds turn
easterly while increasing to 10-15 knots on monday, resulting in
some nearshore choppiness, especially in the western basin. a warm
front approaches the lake on tuesday allowing for winds to shift
southerly while remaining between 10-15 knots. southerly to
southwesterly flow will continue through the remainder of the week.

- daily periodic chances for showers and storms possible through
next weekend. highest chances of around 60% monday afternoon

the stalled boundary over our area this morning has begun slowly
moving southward. the front has completely cleared our area with the
exception being white county, in. chances for showers and storms
remain low today (20-30%) as we end up on the cool side of this
boundary. with a tight instability gradient across northern indiana,
the us 24 corridor and south has the best chances, albeit low, for
seeing a stray shower or storm today. light winds and highs in the
mid 80s are expected this afternoon amidst partly cloudy skies.

a developing upper level low pressure system lifts into the upper
midwest on monday. a few rounds of scattered showers and storms are
expected across the area monday afternoon through tuesday. first,
this upper level low will help pull the stationary front back north
during the day monday. waa strengthens during the daytime hours on
tuesday, bringing warmth, additional rain chances, and allowing for
the boundary to finally clear out.

it will then become hot and humid, especially from tuesday onwards
into late next week. as an upper level ridge builds across the
eastern conus and surface high pressure develops over the southeast
us, an early season heatwave is expected across much of the eastern
us this week. strong southerly flow will allow for heat and humidity
levels to soar in our forecast area. summer-like temperatures in the
upper 80s to low 90s are anticipated with dewpoints in the low to
mid 70s, especially during the peak of this early season heatwave on
wednesday and thursday. the first 90+ degree day is likely for many
locations by the end of the week. while heat and humidity begin to
rise starting early this week, heat indices may approach 100 degrees
during peak heating hours wednesday and thursday. please take the
heat seriously and take steps to prevent heat related illness!

depending on the magnitude and exact placement of the upper
level ridge, there could be daily periodic chances for
rain/storms by mid to late in the week. for now, pops range from
20-60% each day for wednesday and beyond with low confidence on
exact timing and coverage. spc did include much of our forecast
area in their day 5 severe outlook for thursday, june 11th.
models diverge on an exact solution but a cold front could move
through, causing a setup where severe weather with all hazards
could be possible. pattern recognition tells me that this is
often how we break our hot and humid patterns during the
summertime either with a cold front or with storms that ride the
edge of the upper level ridge.... stay tuned!

vfr/dry with easterly winds near 10 knots through monday
morning as any shower/storm activity likely remains southwest
of the terminals near a frontal zone. this front does lift back
north into northern in monday afternoon with renewed chances

- dry conditions with warmer temperatures monday.

- chance of showers and thunderstorms starting monday night. greater
potential exists tuesday, with locally heavy rainfall possible.

- hot and humid wednesday and thursday along with additional
thunderstorm chances.

.discussion...

dry and stable conditions exist to finish the weekend period, as
high magnitude upper level ridging maintains control atop surface
high pressure anchored over ontario. little variation in the
resident profile expected over the next 24 hours. deep column
subsidence held within this environment affords limited cloud
production, while a resident dewpoint of mid 50s to lower 60s
represents the lowest expected humidity over the upcoming week. lows
tonight in the 50s, with highs pushing well into 80s monday as mean
thickness readings peak as the upper ridge apex slips eastward.

higher amplitude upper level trough digging into the upper midwest
will effectively shunt a lower amplitude positively tilted
disturbance currently drifting across the plains northeast toward
the great lakes by early tuesday. strengthening low level jet monday
night along the lead edge of the height falls will initiate a
pronounced period of moisture transport during this time. surface
dewpoint projected to surge sharply into the mid 60s to lower 70s,
with model pwat values approaching 2 inches by tue evening.
supportive large scale ascent tied to the passing wave timed
coincident with daytime heating will yield a high probability for
some clusters of showers and thunderstorms to develop. profile
characterized by high quality moisture at the deep level and
associated weak instability, but lacking in meaningful low level or
deep layer shear. this suggests limited potential for greater
convective organization, although isolated stronger downbursts could
materialize driven by localized precipitation loading. heightened
risk for heavy rainfall exists given expected slow storm motion and
prospective efficient rainfall rate. wpc maintains a marginal risk
for excessive rainfall across lower michigan.

in the wake of tuesday`s system, southwest flow strengthens across a
deep layer within the backdrop of building upper heights. strong low
level warm air advection takes hold on wednesday as 850mb
temperatures climb to near 20c. this sets the stage for an extended
stretch of high magnitude warmth and humidity for the late week
period, as surface temperatures climb into the upper 80s to lower
90s both wednesday and thursday. this occurs while dewpoints remain
locked in the upper 60s to lower 70s. this translates into peak heat
index values solidly in the 90s both days. while larger scale
capping concerns will exist, some convective potential will exist
with reliance on upstream convective behavior. this convective
potential does introduce minor predictability barriers regarding
exactly how high max temperatures will peak each day.

western periphery of a high pressure system will hold across the
great lakes today through tomorrow afternoon. this will maintain dry
conditions along with light winds. winds from the north to northeast
will back to the east-southeast through tomorrow in response to the
departure of high pressure. weak low pressure will then bring some
unsettled weather through the midweek period. some periodic rain
showers with embedded rain showers will be likely on tuesday, with
lower end potential wednesday onwards. the weaker pressure gradient
keeps wind gust potential aob 20 knots outside of any thunderstorm
activity.

very dry airmass in place will continue to support clear to mostly
clear skies through tonight as high pressure is slow to exit the
central great lakes. there was limited low level stratus this
morning that came off saginaw bay/lake huron, which has transitioned
to modest (few-sct) vfr cu field early this afternoon, but is mixing
out as we speak. winds remain light easterly into tomorrow, thus
another low chance for low stratus to develop around mbs late
tonight into early monday.
