.AVIATION...

All TAF sites are still reporting P6SM vsbys this morning, despite
patchy fog elsewhere in the airspace. Any BR/FG development at this
point will be brief with sunrise already well underway. High
pressure currently located over Lake Erie affords another dry and VFR
forecast period, with the only cloud nearby coming from the MCS well
to our northwest. Winds veer to the southwest this afternoon but
remain light with peak speeds aob 7 knots before returning to the
south tonight.

For DTW/D21 Convection...there is a low chance for thunderstorms to
develop between 16z and 18z Monday, although the better opportunity
exists after 18z.

THRESHOLD PROBABILITIES...

* Low chance for thunderstorms between 16z and 18z Monday.

DISCUSSION...

The center of 1019mb surface high pressure will build across the
central Great Lakes aggregate this morning to portions of PA and
upstate NY by this afternoon. NWP progs are very aggressive in
advecting/lifting a relatively shallow 950-850mb warm front through
the area into the Lake Huron basin by the afternoon. Expecting a
combination of deeper mixing and an uptick in surface dewpoints to
bring very warm conditions, heat indices in the lower 90s, although
the relatively shallow thetae return will maintain higher static
stability and convective inhibition between 2.5 and 7.0 kft agl.

A midlevel trough will push through the Great Lakes region Monday
and Tuesday. Forecast data depicts a trough that will remain in a
positive tilt while harboring 2 disorganized shortwave maxima. The
main geopotential height fall response with the system is expected
to occur during the daytime Monday as ragged, weak lead wave energy
ejects northeastward in advance of the trough. Magnitude of surface
based instability at 2000-3000 J/kg Monday will bring a strong to
severe thunderstorm threat but the lack of kinematics will limit 0-
6km bulk shear to 25 to 35 knots during the late afternoon. Storm
mode of multicell may support damaging wind gusts between 2pm-10pm
Monday with precipitation loading and wet microbursts. The potential
does exist for some isolated short live linear structures as
convective transitions to outflow dominant.

Northwesterly flow system relative isentropic descent will bring
subsidence and a modest lowering of humidity for the middle to end
of the week. More comfortable, but nonetheless, classic summer
weather conditions are anticipated. Looking at daytime highs in the
80s Tuesday through Friday (0 to 5 degrees above normal) with
dewpoints predominately in the 60s. There doesn`t appear to be much
potential for organized precipitation during middle to end of
the week period.

MARINE...

Light winds and low waves over the Central Great lakes to start the
day as a ridge of high pressure exits east. As a result, light
southerly flow under 20 knots develops this afternoon ahead of the
next low pressure system, which enters the northern Great Lakes
Sunday night into Monday driving a stronger cold front through the
region. This cold front will provide additional storms Monday and a
stronger post-frontal wind field Tuesday, around 20 knots
