Update Initial area of light rain working towards western cwa.

Made some minor pop adjustments there. Otherwise no changes.

Pc

Aviation(12z tafs) Vfr conditions at the outset will likely
trend towards MVFR as rain thunderstorms move in later this morning
and into the afternoon hours. Ese winds gradually increase north
of a warm front. Later today into this evening there will be
potential for more storms as low pressure approaches and may bring
the warm front back into portions of far southern wi. This would
enhance the potential of some severe storms especially closer to
the wi il border. Stay tuned to later forecasts and updates as the
severe potential will largely be predicated on airmass near the
warm front after the late morning afternoon round of rain storms
moves through.

Prev discussion (issued 314 am cdt Mon may 27 2019)
short term...

today and tonight - confidence... Medium
concern has been heightened with regards to severe potential
later this afternoon into the early evening hours with the focus
of this towards sc wi and closer to il border warm frontal
proximity. In the short term initially dry airmass with lingering
anticyclonic influence, will give way to lower level thermal moist
advection. Showers some thunderstorms likely to be delayed some
but still move into sc wi this morning and trend into the eastern
cwa early this afternoon. Not expecting severe with this batch but
some locally heavy downpours possible. Forcing will be enhanced
by a mid level shortwave that starts to increase DCVA into the sc
later this morning and then shifts into the eastern CWA for the
afternoon. So will delay pops a bit from the outset today and then
gradually ramp things up. Big question will be later day evening
development which will hinge on where effective boundary sets up
in response to the first wave of rain. Seeing some signals where
this front could hang up across far NW il into parts of SW or sc
wi. What's also concerning is that basically all of the models are
now bringing the surface low through SRN or cntrl wi boosting the
potential that the better airmass could be pulled further north
into our area. Airmass would have the potential to become unstable
with decent hodograph in vicinity of warm front. Progs show SW 850
jet core that could override some SE surface winds. 700 millibar
and 500 millibar winds are more westerly. The overall shear could
be be rather impressive. Again this is all dependent on how airmass
responds after the later morning afternoon round. But concern at
this time focuses across the southern CWA where we are adjacent to
spc enhanced risk across NRN cntrl il and where the likelihood
would exist for some late day early evening destabilization which
lead to a more primed airmass for severe storms. Coverage of storms
is proggd decrease as the night wears on.

Long term...

Tuesday through Wednesday night... Forecast confidence low to
moderate...

the forecast for Tuesday and Wednesday remains tricky this
morning. Shortwave ridging behind the shortwave moving through
this afternoon evening should help support a period of relative
calm to start the day on Tuesday. Surface flow will become
northerly late tonight into early Tuesday, which will advect some
drier air into the region. These factors may in fact keep the
region dry for most of the daytime hours on Tuesday. The closed
upper low currently located over the southwestern CONUS will move
into the central plains on Tuesday, with convection developing
across eastern nebraska and much of iowa on Tuesday afternoon.

This activity will push east into northern illinois and southern
wisconsin Tuesday evening into Tuesday night. For now, it looks
like the bulk of the stronger instability may remain to our south,
which would result in a relatively low severe weather threat.

Overall confidence is low, however, as much will depend on how
today and tonight's thunderstorm activity evolves.

Thunderstorms will likely be ongoing across at least parts of the
region Wednesday morning. The upper low will continue to slowly
pinwheel east across nebraska, while gradually weakening. As
various pieces of energy emanate from that low and lift across
the region, expect to see several waves of showers and
thunderstorms. Despite the arrival of higher surface dewpoints,
think that there will be little opportunity for clearing, and thus
appreciable destabilization on Wednesday, limiting the severe
weather risk.

Thursday and Friday... Forecast confidence moderate...

the upper low will continue to fill and will eventually move east
of the area by later Thursday. Showers and thunderstorms will
remain possible across the area, especially during the first part
of the day on Thursday, with diminishing potential Thursday
afternoon and night. Friday currently looks to be mostly dry, with
the region situated within an area of large scale subsidence.

Next weekend... Forecast confidence moderate...

the active pattern looks to continue through next weekend. While
it's too early to nail down particular details, periodic
shortwaves look to move through the great lakes, interacting with
a relatively moist airmass. This should result in multiple
chances for showers and thunderstorms through the period.

Temperatures will likely be around or a touch below climatological
averages, given what is likely to be considerable cloud cover.

Aviation(09z tafs)...VFR conditions at the outset will likely
trend towards MVFR as rain thunderstorms move in later this morning
and into the afternoon hours. A gusty ese wind will be in place ahead
of a warm front. Later today into this evening potential for more
storms as low pressure approaches and may bring the warm front back
into portions of southern wi. This would enhance the potential of
some severe storms especially across the southern portions of our
forecast area. Stay tuned to later forecasts and updates as the severe
potential will largely be predicated on airmass near the warm front
after the late morning afternoon round of rain storms moves through.

Marine... High pressure will shift east of lake michigan quickly
this morning as low pressure approaches from the plains. The low
is expected to move across southern lake michigan tonight and to
the east Tuesday. Winds will vary across the lake today and tonight
due to the track of the low across lake michigan. Developing east
winds will become more southeast or south in the southern portion
of the lake as the low draws closer. Winds will remain northeast
or east in the northern portion of the lake. As the low shifts to
the east tonight into Tuesday the winds will turn northerly across
the entire lake. Will issue a small craft advisory for our
northern two nearshore zones for tonight due to the onshore winds
and subsequent building waves.
