Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
1258 PM CDT Tue Jul 2 2019

.UPDATE...The forecast is on track for this afternoon into this
evening. Sct showers and tstorms are still expected to develop.

&&

.AVIATION(18Z TAFS)...Sct-bkn035-040 cumulus or cumulus congestus
this afternoon and early evening. Local MVFR Cigs are possible as
well. Sct tstorms are forecast to develop this afternoon and
linger into the evening. Areas of low stratus anywhere from
200-1500 feet are expected to develop after midnight and last
several hours beyond sunrise on Wed. Areas of mainly light fog
of 1-3SM, locally lower, are also expected to develop after
midnight. The fog and stratus will then lift into sct030-040
cumulus for the afternoon.

&&

.PREV DISCUSSION... (Issued 1028 AM CDT Tue Jul 2 2019)

UPDATE...An outflow boundary has moved south into nrn IL and will
likely remain there today while another weak boundary or weak cool
front will set up over central WI this afternoon and evening. An
additional boundary will be the lake breeze over ern WI. A couple
vorticity maximums or MCVs currently over srn MN and ne IA will
move across the region this afternoon and early evening providing
some upper support to the weak low level convergence along the
boundaries. MLCAPE of 1000-2000 J/Kg has already developed away
from the lake and south of the cloudy region over central WI. It
is expected to build to at least 2000-2500 J/KG for much of the
area this afternoon with little to no capping. Thus, more sct
tstorm development is expected across srn WI with a Marginal Risk
for pulse SVR storms into the early evening.

For Wed, the weak cool front and outflow boundaries will likely
set up from ne IA into nw IL but remain sufficiently close for
chances for more tstorms for sw WI. Dry conditions are expected
for the MKE metro area and locations to the north.

MARINE...Prevailing winds will remain relatively light this week
along with low wave heights. Intermittent areas of dense fog will
be possible during the week due to a humid airmass over the
relatively cool waters of Lake MI.

PREV DISCUSSION... (Issued 551 AM CDT Tue Jul 2 2019)

UPDATE...

The storms continue to remain north of Madison and Milwaukee as
expected. The current round should push out within the next hour
or so, with somewhat quiet conditions then through late morning.
Still looks like more storms will be possible this afternoon and
evening.

AVIATION(12Z TAFS)...

There will be a chance for storms today into tonight. The best
chance through the early morning hours will be mainly north of
Madison and Milwaukee. Storms will then be possible across
southern Wisconsin during the afternoon and evening hours, winding
down north to south overnight as high pressure builds in. A few
storms could be severe, mainly during the afternoon and evening.

Other than lower ceilings/visibilities within thunderstorms, VFR
conditions are expected into tonight. Given enough clearing,
could see some fog develop later tonight.

PREV DISCUSSION... (Issued 315 AM CDT Tue Jul 2 2019)

DISCUSSION...

Today and tonight...Forecast confidence is medium:

A weak low pressure system will approach this morning, moving
through during the afternoon and evening hours. A chance of storms
will continue this morning as the low draws near, mainly north of
Madison and Milwaukee where there is a lingering low level
boundary. The chance for storms is then expected across the
forecast area this afternoon into evening. Models are varying a
bit with where the boundary will be hanging out when the afternoon
storms fire, so kept storm chances at 50 percent due to the
uncertainty.

Given some holes in the clouds today, should be enough heating for
decent instability for the afternoon/evening storms. Mid level
lapse rates and shear aren't very impressive, though a few strong
to severe storms will be possible given the instability and
forcing. Strong winds would be the main threat with any storms
that do reach severe levels.

It looks like most of the activity should wind down by around
midnight as the boundary sags south of the area and high pressure
begins to build in. Given enough clearing, could see some fog
develop later tonight.

Wednesday through Saturday...Forecast confidence is medium.

Subtlety is the nature of the forecast for the rest of the week.
The pressure pattern at the surface is quite weak while the mid
levels will feature periodic short waves in a somewhat fast zonal
flow on the northern periphery of a srn CONUS ridge.

For Wednesday, it looks like a weak surface cold front will be
south of the border in the morning. Therefore, it should be dry
in the morning, but that front may try to push back north during
the afternoon, resulting in a small chance of afternoon
showers/storms mainly over south central areas. Overall,
Wednesday looks pretty dry with warm temps in the 80s.

Independence Day, we will have that weak surface front across the
area...coupled with good model agreement on a mid level wave
likely pushing across the area. This should result in showers and
storms developing during the day, but subsidence in the wake of
the short wave in addition to diurnal stabilization may allow
things to dry out by the time evening fireworks commence. It will
be warm and quite humid with highs solidly in the mid 80s and
dewpoints around 70.

Friday and Saturday will feature a similar scenario to Thursday.
The weak surface pattern will be highly influenced by any
convection over the prior days, but there's still good model
agreement on a few more short waves pushing through. So, expect
mostly diurnally driven convection here with temps remaining in
the 80s.

Sunday and Monday...Forecast confidence is medium.

The guidance has been persistent in showing cooler high pressure
building across the Great Lakes for the first part of next week.
This should dry things out and cool those afternoon highs into the
70s, especially on Monday. We should also get a temporary reprieve
from those high dewpoints.

AVIATION(09Z TAFS)...

There will be a chance for storms today into tonight. The best
chance through the early morning hours will be mainly north of
Madison and Milwaukee. Storms will then be possible across
southern Wisconsin during the afternoon and evening hours, winding
down north to south overnight as high pressure builds in. A few
storms could be severe, mainly during the afternoon and evening.

Other than lower ceilings/visibilities within thunderstorms, VFR
conditions are expected into tonight. Given enough clearing,
could see some fog develop later tonight.

MARINE...

Winds and waves will be on the low end through much of the
rest of the week, with a continued chance for thunderstorms most
days. Some of the storms may be severe later today. There could
be some fog over the lake at times through the next few days given
the warm and humid airmass, with the best chance over open waters
where the water is colder.
