.what has changed...
the forecast remains generally on track with no significant
changes.

.key messages...
1) below normal temperatures and dry conditions will trend towards
seasonal values by saturday.

2) chances of showers and thunderstorms return sunday into the early
part of next week.

key message 1...
upper level trough responsible for the cooler airmass over the
region will pivot east into new england on thursday. meanwhile
high pressure will expand at the surface across the central
great lakes maintaining cool and dry conditions to end the week.
overnight lows through thursday night will be in the low 50s
and high temperatures will gradually warm 3-5 degrees each day
through saturday. a healthy cumulus deck of clouds is expected
inland again on thursday but will tend to clear late afternoon.
mostly sunny to partly cloudy conditions continue through
saturday.

key message 2...
active weather will return sunday into monday as the upper
level ridge expands eastward into the central great lakes
accompanied by the moisture and instability axis. dewpoints
return to the mid 60s with ml cape values of 1000-2000 j/kg on
sunday. a shortwave moving through the northwest flow aloft will
likely provide a focus for scattered thunderstorms and
sufficient shear is expected for some storms to be strong. by
monday a warm front will be in the vicinity and likely act as a
focus for additional thunderstorm activity. given uncertainty in
placement and coverage will keep most areas at scattered
coverage for now but could trend up once we gain confidence in
timing. temperatures will trend back to more summer like
conditions with highs in the mid to upper 80s and increasing
humidity to start the week.

.aviation /18z wednesday through monday/...
vfr conditions are expected through the taf period as high pressure
builds into the great lakes region. few/sct clouds around 5kft
will continue at times through the period. light and variable
conditions through tonight become out of the north around 5
knots during the day thursday.

outlook...non-vfr possible with periodic showers and
thunderstorms sunday through monday.

.marine...
conditions across lake erie have improved over the course of the day
and the small craft advisory and beach hazard statement have been
cancelled. high pressure builds into the region this evening with
winds subsiding to less than 10 knots out of the north overnight
with waves subsiding to 1 to 3 feet. winds will become less than 5
knots and variable thursday morning through much of friday. the high
pressure will drift off to the east by early saturday and winds will
shift to be out of the south to southwest at around 5 knots. late
saturday into sunday, a tough will move through the great lakes with
winds shifting to be out of the west at around 10 knots into
monday.

behind yesterday`s cold front, surface high pressure noses into the
area and continues affecting us with drier conditions and below
normal temperatures until saturday. looking at naefs climatology
between mid july and early august on the ensemble sit table, 850 mb
temperatures cooler than 8c happens about once in every 10 yrs or so
in parts of n in and nw oh midday today. the coolest night in this
period is tonight and then we slowly warm with lows back above 60
degrees again saturday night.

a strong theta-e plume pushes back through the area midday saturday
with 70 degree dew points returning overnight and 850 mb
temperatures achieving 18+c again by sunday morning. at this point,
we have a ridge over the western us and a trough over the eastern
us, putting our area in a northwest flow regime, which would seem to
indicate the possibility of mcss or ridge riders. sunday morning has
what appears to be an outflow boundary or at least some sort of
temperature gradient entering the area. then there appears to be a
more concrete upper pv anomaly associated with upper divergence and
sfc convergence on the gfs (with some model confluence from the
ecmwf with having a similar pv anomaly moving through sunday
morning) that usually occurs in the vicinity of mcss perhaps
indicating the potential for such an occurrence sunday afternoon
depending on the state of the area after the morning outflow
boundary. we actually have some effective shear around on saturday
into saturday night, but instability appears rather weak at less
than 1000 j/kg. shear is gone by the time we get into sunday though.
perhaps another opportunity for stronger storms is some time on
monday. the gfs has better shear in the morning with thermal
boundaries around as well as instability. the wxnext ai model
indicates the best chance for severe weather is that monday time
frame.

a broad area of midwest high pressure builds into southern lower mi
and the ohio valley tonight and thursday. it provides ideal aviation
conditions as high based cumulus gradually dissipates this evening
leaving clear sky and light wind late tonight through thursday
morning. a fair weather cumulus field returns thursday afternoon but
with less coverage compared to this afternoon. these clouds
dissipate in favor of clear sky again for thursday evening.

thursday.

dissipating right jet exit region over southern lower michigan is
still facilitating upper level convergence, leading to a weak
subsidence tendency. this occurs as longwave troughing remains
entrenched across most of the great lakes region for the next 24
hours, with a vortmax sweeping across northeast lower and northern
lake huron. forecast soundings indicate a seasonably dry column with
the 22.18z kdtx raob measuring a pwat near 0.55 inches, below the
climatological 10th percentile. diurnal cumulus positioned just
below a 5 kft inversion layer wanes this evening, after the boundary
layer decouples. expect mostly clear skies overnight as surface high
pressure builds southeastward. winds trend toward calm after
midnight as the gradient relaxes.

the surface ridge centers over chicago on thursday with the longwave
axis departing east. this results in mid level flow turning zonal
amidst geopotential height rises. 850 mb temperatures are forecast
to moderate, given the anticyclonic orientation to the lower column
flow. warm advection setup lifts values to around 11c by thursday
afternoon, marking a steady warming trend that should progress
through the weekend. favorable insolation conditions arise given a
low cloud fraction and weak winds, lifting highs into the upper 70s.

the current stretch of dry weather persists friday as the center of
the anticyclone drifts east, settling over the ohio valley. this
causes surface flow to back toward the south-southeast, initiating
the gradual rise in dewpoints over the weekend. winds aloft begin to
strengthen friday night and into saturday as the synoptic pattern
becomes more active. a large ridge over the western half of conus
amplifies with stronger embedded flow rounding the apex. this
interfaces with a deep upper low over hudson bay. expect the
resident dry air to delay saturation until late saturday or early
sunday, ahead of an ejecting ridge-running shortwave targeting
southeast michigan. showers and storms are possible with this wave
as moisture/instability increase. sunday or monday appears to be the
warmest day of the forecast period, with highs briefly breaking
above normal, into the upper 80s.

marine...

northwest winds peaked late this afternoon in the 20 to 30 knot
range as low-level cold advection has largely exhausted itself.
however, elevated waves over the southern lake huron basin will take
time to subside below 4 feet; small craft advisories remain in
effect into the evening hours.

850 mb temperatures, currently at or slightly below 7 c, will
gradually warm over the next couple of days, reaching around 12 c on
friday. with the center of the surface ridge over the southern great
lakes thursday into friday, the lightest winds will be over lake st.
clair and lake erie. even over lake huron, wind speeds should remain
predominately under 20 knots. a surface trough slowly passing
through during the weekend will bring a good chance of showers and
isolated thunderstorms, though winds are expected to remain light.
