.what has changed...
the forecast largely remains on track and no significant changes
were needed with this update.

&&

.key messages...
1) cool temperatures and dry weather expected tonight.

2) an unsettled and humid weather pattern returns tuesday
through late week. a few strong storms are possible in northwest
ohio tuesday night, although confidence is low.

&&

key message 1...
high pressure will remain in place over the region through
tonight. clear skies will allow for efficient radiational
cooling and expect lows in the upper 40s and lower 50s. a few
spots across interior ne pa may manage to drip into the low to
mid 40s if cooling ends up being more efficient than currently
anticipated. this will be the last chilly night of the workweek
before temperatures warm up tuesday onwards.

key message 2...
after a brief break in the unsettled weather pattern, multiple
rounds of showers and thunderstorms will likely impact the area
late tuesday through at least thursday. the first round of
showers and thunderstorms will arrive behind a warm front and
with a pre-frontal trough tuesday evening. there is a small
chance of a couple of stronger storms tuesday evening into
tuesday night, although most cams suggest that the best
instability will be to the west of the local area and storms
will be coming in during a diurnally unfavorable time of day.
the severe weather risk may be a little bit higher if storms end
up moving in earlier than currently anticipated, but either way
bulk shear values of around 30 knots supports an spc marginal
risk (level 1 of 5) of severe weather with damaging wind gusts
being the main concern.

from there, a cold front will push southeast across at least a
portion of the area before slowing and wavering over the region
wednesday through late thursday. this will result in periodic
showers and thunderstorms for the mid to late week timeframe.
there may be opportunities for a few stronger storms given the
proximity of the front, but there is still uncertainty in the
exact placement of the boundary and the amount of instability in
place each afternoon. will need to keep an eye on the forecast
and update as needed.

it will also be quite humid and warm across the area with highs
in the 80s and dew points in the upper 60s and low to mid 70s
wednesday and thursday. pwat values will increase to 1.5 to at
least 2 inches during this time and flow parallel to the
boundary may result in potential in heavy rainfall rates and
training showers/thunderstorms.

&&

.aviation /18z monday through saturday/...
high pressure continues to provide for cooler, drier, and vfr
conditions through the taf period. few-sct cumulus around 4000
feet across parts of ne oh/nw pa will continue to clear out
through this evening. high clouds will filter through at times.
fog is generally not expected tonight due to a light breeze.
speaking of, north-northeast winds at under 10kt this afternoon
will remain light while shifting south-southeast tonight. winds
increase to around 10kt out of the south-southwest on tuesday.

outlook...non-vfr at times in scattered showers/storms tuesday
night through thursday night.

&&

.marine...
light and variable winds will continue through early this
evening before shifting to the southeast and increasing to 10 to
20 knots ahead of an approaching warm front tonight into tuesday
morning. there may a brief period where winds in the nearshore
zones (especially in the western basin) touch 20 knots tuesday
morning, however confidence in winds of 20+ knots is highest in
the open waters. have opted against a small craft advisory for
the time being, but will need to keep an eye on wind speeds.
the offshore winds will mitigate wave heights and keep the risk
of rip currents relatively low. offshore winds will diminish to
roughly 10 to 15 knots tuesday evening with flow becoming more
southwesterly behind the warm front tuesday night into early
wednesday. northeast winds of 10 knots or less are expected on
the lake as a frontal boundary wavers over the region wednesday
with flow becoming variable thursday through the end of the
week. winds/waves should remain below small craft advisory
limits late this week.

very pleasant temperatures in the 70s and dewpoints in the 40s will
shift away as the sfc ridge moves east and an increasing low level
flow starts ushering much higher dewpoints to the area. this will
take a bit of time, with values into the low to mid 50s by 12z tue.
off to our nw, an axis of much higher dewpoints will be pooled along
a slow moving frontal boundary that is expected to approach later
tomorrow and linger across the region (in a weaker state) through
thursday. dewpoints and low level temps will climb through the day
with a much more muggy feel returning by afternoon. high temps
before any convection occurs will reach well into the 80s for most
locations and if cloud cover stay away long enough, a few 90s are
possible in sw areas.

models have generally backed off on upstream convection making it
into nw parts of the area as it encounters the drier air mass and
outruns the better forcing. as we move into tuesday afternoon and
beyond, this changes with at least chance pops warranted as leftover
outflow boundaries that may drift in during peak heating interact
with increasing cape. there seems to be a continued lean towards
better development in the 20 to 22z time frame, mainly nw but
honestly could end up just about anywhere. these then progress
southeast through about 2z to 3z wed before shifting out of the area
or weakening. shear profiles are on the lower side (25 to maybe 35
kts) for some organization of convection, and decent low level lapse
rates will help with the initial lift, but mid level lapse rates are
quite unfavorable for more robust convection. spc has maintained the
marginal risk for severe storms with some gusty wind potential for
those storms that can interact with boundaries and maybe sustain
some briefly better updrafts and cores.

beyond 6z wed forecast becomes even more challenging as frontal
boundary slowly weakens and stalls over the general area with models
struggling (as to be expected) with the handling of subtle waves and
possible new development or propagation of upstream convection.
given the amount of lingering moisture in the area and at least some
instability, it won`t take much to pop additional showers and
storms, thus warranting the chc to likely pops through thursday. by
no means does it look like a washout with periods of little/no
precip likely in between waves, but no way to time those out at this
point in the forecast. severe threat should be very minimal, if non
existent, but heavy rain/localized flooding could become an issue
with high pwats and any repeated training of multiple rounds of
convection. marginal risk for excessive rainfall remains in place
tue and wed and is reasonable.

no changes beyond thursday as models seem to want to push the
ridging north into mi for the weekend. however, history over the
past several weeks in this setup has pointed towards low confidence
on how much of this comes to fruition. as a result, blend is left
alone with some slgt chc to chc pops, especially sat.

mid/upper level clouds will continue to increase through the
evening as the next trough and associated warm front approach
the region. this front could touch off a few showers/storms at
ksbn 12-16z but confidence is low (30-40%) due to better
forcing and moisture convergence setting up just north of the
terminal and poor diurnal timing. some marginal llws is also
possible at ksbn tue morning. much quieter conditions will
persist at kfwa given further displacement from the main front
but thunderstorms will be likely there tue evening.

high pressure has led to a dry but cool day across se michigan. many
locations have seen temperature readings hold in the upper 60s, even
under plenty of sunshine. anticyclonic surface wind pattern over
western michigan identifies the center of the surface high, which
will drift overhead this evening and cause winds to back to the
southeast. flow backs further to the southwest overnight, drawing a
theta-e ridge into the great lakes region tuesday. this brings
warmer temperatures, increased rain chances, and breezy southwest
flow to se michigan.

the theta-e surge will be aided initially by a belt of ~50 to 60
knot h8 winds late tonight, driven on the larger scale by se conus
high pressure. the nose of the jet reaches northern michigan early
tuesday morning, focusing a broad area of precipitation toward the
saginaw valley for the first half of the day. a deep closed low
across ontario will simultaneously drag a cold front across northern
conus, which will push rain chances eastward and thus into the rest
of the cwa through the day tuesday. one questionable aspect of this
system is how well the stratiform rain can hold up against the dry
airmass sampled overhead today (pwat of 0.44" per 12z kdtx sounding
for reference). soundings are showing a good amount of dry air
surviving at the low levels, which could eat into qpf amounts and
even rain chances altogether, especially as the low level jet
forcing departs mid-day tuesday. the waning llj presence will still
be enough to produce breezy conditions with gusts of 25 to 30 mph
possible.

as the cold front and associated moisture convergence arrive tuesday
afternoon-evening, event character becomes more convective with
showers and thunderstorms redeveloping along the boundary.
instability is not expected to be overly impressive, but several
models bring 70 degree dewpoints across the state line tuesday
evening which is enough for about 1000 j/kg mlcape. this occurs in a
fairly tight time window between about 21z-01z (5pm-9pm) south of i-
94. swody2 continues to designate a marginal risk for severe weather
across lenawee/monroe counties, mainly for isolated precipitation
loaded downbursts in a marginal shear environment. the broader
threat looks to be heavy rainfall, especially given the high
moisture environment and proximity of the frontal zone. more details
are in the hydrology section.

se michigan through the rest of the work week will be in the hands
of the frontal zone. the baroclinic zone certainly stays within
reach of us, but models generally shove it into the ohio valley for
wednesday before lifting back north thursday-friday. broad brushed
pops reflect the uncertainty in coverage/timing of this pattern
rather than a full wash out over the next several days. wavering
nature of the frontal zone will also cause temperatures to waffle
between 70s and 80s through the rest of the work week with unsettled
conditions possibly extending into the weekend.

strong high pressure over the great lakes tracks eastward this
evening, giving way to a mature low pressure system over the upper
midwest. this system advances across northern ontario on tuesday and
directs a strong southerly low-level jet across the region. the
strongest winds are still on track for northern lake huron where
gales to 35 to 40 kt are forecast. a gale warning remains in effect
north of alabaster from 4 am to 4 pm. farther south, gusts of 20 to
30 kt will be more common and small craft advisories remain in
effect for the lake huron nearshore waters. a band of showers with a
few embedded thunderstorms accompanies the gale event with highest
coverage across lake huron during the morning. additional scattered
showers and thunderstorms are forecast across lake st. clair and
western lake erie during the late afternoon and evening ahead of a
cold front. this front eases across the area tuesday night, bringing
the end to showers and causing wind to shift from south/southwest to
north/northeast by wednesday morning.

.hydrology...

a moisture rich airmass surges into the region tuesday ahead of a
cold front which tracks through in the afternoon and evening. the
front then stalls out across the northern ohio valley before lifting
back north later this week. this will result in multiple
opportunities for widespread rainfall throughout the week. in the
near-term, the best opportunity for heavy rain will be south of i-69
tuesday afternoon and evening where thunderstorm development may
enhance rainfall rates to over an inch per hour. depending on where
the front stalls, rain may linger overnight to produce storm totals
over one inch by wednesday morning with training storms not out of
the question. localized ponding or minor flooding of low-lying or
urban areas will be possible.

high pressure centered over the region is making for a quiet day
with just a few diurnal cu developing under an increasing canopy of
cirrus. clouds will continue to thicken and lower through the night
as moisture rides up over a warm front approaching the area in the
early afternoon tuesday. a band of showers will accompany the front
beginning predawn at mbs and drifting southeast through the morning.
most guidance suggest an overall weakening trend while passing
through the state so confidence is higher for mbs and fnt than down
toward dtw. there remains a very low chance of an embedded
thunderstorm so will not include in the tafs yet, but will tempo a
brief period of heavier rain. cold front passes through around 00z
with a chance of a second line of showers or thunderstorms
developing but that is mainly outside of dtws taf period so will
just note here for now. winds become southeasterly this evening and
tonight before becoming gusty tomorrow ahead of the cold front.

d21/dtw convection...no thunderstorms are forecast through tuesday
afternoon.

* low for ceiling 5000 ft or less through tuesday morning.
