Area Forecast Discussion
National Weather Service Green Bay WI
244 AM CDT Thu Aug 3 2017

Forecast discussion for routine morning forecast issuance

.SHORT TERM...Today...Tonight...and Friday
Issued at 244 AM CDT Thu Aug 3 2017

Scattered showers and a few thunderstorms continue across central
and northeast Wisconsin early this morning associated with weak
isentropic lift ahead of an approaching low pressure system across
the upper Mississippi Valley region.

As the slow moving low moves through the western Great Lakes today
and tonight it will bring several rounds of showers and
thunderstorms to the area. Upstream radar observations indicate
that its not a matter of if it will rain, rather how much will
fall and and will it be severe. The area appears poised to receive
a widespread 1 to 2 inches of rain given the moisture and potent
dynamics associated with the system. Locally higher amounts are
possible given the nature of thunderstorms, with localized
flooding possible from torrential rains in stronger thunderstorms.

The other concern is severe potential given the high amount of
shear available with bulk shear values of 40 to 50 knots. The main
factor in question is the amount of instability that will be
available across the area. The models suggest MUCAPEs could be as
high as 1-2 J/g during the afternoon and evening hours. Closer
inspection of the CAPE indicates it will be very long and skinny,
which would make it tough for severe weather. In addition the
amount of MUCAPE the models are suggesting may be a bit high given
the expansive cloud cover currently in place and the amount of
cloud cover upstream. There aren't significant breaks in the
clouds to suggest the atmosphere will be able to realize that much
instability this afternoon. Therefore while the potential for
damaging winds is certainly possible given the shear values, there
are certainly a lot of factors going against the severe potential
across the cwa this afternoon and this evening.

Showers will slowly end from west to east on Friday as the low
moves away from the western Great Lakes. In its wake much cooler
temperatures are on tap as highs are limited to the 60s. In
addition a tight pressure gradient will bring gusty north to
northwest winds of 20 to 30 mph, particularly across northeast
Wisconsin.

.LONG TERM...Friday Night Through Wednesday
Issued at 244 AM CDT Thu Aug 3 2017

Focus of this forecast revolves around precip chances this weekend
and will lean on the ecmwf for the details.  For later periods,
models diverge significantly by the middle of next week, when the
next system is due to arrive.  Will therefore let the multi-model
blend populate the forecast for next week.

Friday night through Saturday night...A few showers may linger over
far northeast WI early in the evening.  Otherwise, should see
clearing skies from west to east with breezy northwest winds
diminishing during the evening.  Then a weak shortwave will bring in
more clouds for Saturday.  With daytime heating, surface based capes
between 500-1000 j/kg appear possible during the afternoon, which
could result in isolated to scattered showers and storms developing.
These should dissipate with loss of heating on Saturday evening,
leaving scattered clouds for the rest of the night. Temperatures
will be comfortable over this period, and slightly below normal.

Rest of the forecast...More showers and storms are possible on
Sunday into Sunday evening when a more vigorous shortwave trough
arrives from the northwest.  Coverage should be greater than on
Saturday due to stronger forcing and slightly higher instability,
though severe weather is not expected.  A few showers could also pop
on Monday afternoon over northern WI with flattened upper troughing
lingering overhead.  Then will be looking at a the next
shortwave/cold front arriving around midweek.  Temperatures will
remain slightly below normal over the period.

.AVIATION...for 06Z TAF Issuance
Issued at 1020 PM CDT Wed Aug 2 2017

Remnants of the convection over central Wisconsin Wednesday
afternoon continue to weaken late this evening and drift over
parts of east central Wisconsin. Mainly mid level VFR clouds were
noted along with patchy MVFR cigs with the lingering light
showers late this evening. After these light showers run their
course the next few hours, focus turns to the approaching
deepening short wave trough and developing surface low. A
widespread rain will work over the state Thursday into Thursday
night. Progs continue to track the fall like surface low west to
east across the central wisconsin. Showers will be more numerous
on Thursday while cigs deteriorate over most locations late
Thursday morning into Thursday night. Scattered thunderstorms
likely, especially along and north of the warm front.

Thursday evening over east-central and portions of central
Wisconsin. A few of the storms could be strong to severe,
and produce damaging winds and large hail. Meanwhile, a more
persistent rainfall with some embedded thunderstorms is expected
farther to the north and west, across north-central and far
northeast Wisconsin. Heavy rainfall is possible across the entire

severe weather during this period.
