Area Forecast Discussion
National Weather Service Green Bay WI
320 PM CDT Fri Apr 14 2017

Forecast discussion for routine afternoon forecast issuance

.SHORT TERM...Tonight and Saturday
Issued at 320 PM CDT Fri Apr 14 2017

Clouds spread across most of the area during the day and there
were a few light showers/sprinkles. The rain was in a northwest to
southeast band of moisture and warm advection around 850 mb. As
of 20Z radar indicated little or no precipitation in the forecast
area.

Models indicated elevated CAPE, so showers and storms can be
expected this evening and overnight as a warm front and a mid
level short wave trough push northeast across Wisconsin. The front
is expected to be through most of the state by 12Z Saturday, and
by 18Z the entire forecast area is in the warm sector of the
surface system where surface winds and low level moisture will
increase. Models continued to show QPF in the area Saturday
morning though little upper level forcing is evident and the cold
front first reaches northwest Wisconsin around midday.

Later in the day thunderstorms are expected as a mid level short
wave and approaching cold front encounter some surface
instability. There is a marginal risk of severe storms across
about the southern two rows of counties in the forecast area where
winds increase considerably in about the first 2000 feet.

Rainfall totals are forecast to be highest, in excess of 0.5" over
much of the area from 06Z to 12Z tonight, so the Menominee River and
Wisconsin River are likely to rise even more.

.LONG TERM...Saturday Night Through Friday
Issued at 320 PM CDT Fri Apr 14 2017

The threat for severe weather will continue Saturday night as a
cold front sweeps through the western Great Lakes region. While
MLCAPE values of up to 1 j/g and 0-6 km bulk shear values of 40
to 45 knots ahead of the front lend themselves to a lingering
severe weather threat during the evening hours, the severe weather
threat itself appears to be marginal and mainly limited to the
southern portion of the cwa given the late arrival of the system
dynamics. The main threat appears to be damaging winds with linear
type convective mode, however large hail cannot be ruled out.
Given many area rivers are already at bankfull, some flooding is
possible given the long skinny CAPE profiles and amount of rain
expected from this system. However the quick moving nature of the
system itself could help mitigate the flood threat. The severe
weather threat drops precipitously after midnight as the cold
front moves east.

A period of dry weather will follow behind the front Sunday and
Monday as a secondary cold front tracks through Sunday night
without much fanfare. While temperatures behind the main front
Sunday will bring a drop in temperatures, a more noticeable drop
will occur Monday behind this secondary cold front. Model
soundings are fairly dry with this secondary cold front, therefore
will maintain a dry forecast with this feature. The next chance
for rain arrives Tuesday and Tuesday night as a low pressure
system tracks through the western Great Lakes. Although there is
still some model discrepancy, there appears to be enough agreement
to raise pops during this period into the likely category for
Tuesday afternoon and evening given the general pattern of the
main dynamics tracking through during this period. The thunder
threat appears to remain south during this period with the main
instability, however if the system trends north will put thunder
chances in as appropriate in subsequent forecasts.

Behind this system another one takes aim for the region Wednesday
and Thursday. However this system has serious issues with respect
to timing and intensity amongst the models. Therefore will
maintain the low chancy pops across the region given the high
level of uncertainty. Beyond this system the models do seem to
agree on another period of dry weather to end the work week next
Friday. Temperatures during this stretch will generally be around
normal for this time of year.

.AVIATION...for 18Z TAF Issuance
Issued at 104 PM CDT Fri Apr 14 2017

VFR conditions prevailed across the area at 17Z as clouds
continued to move in from the southwest. There were some light
showers/sprinkles in parts of central and east central Wisconsin
that were generally weakening as they moved northeast. An
approaching warm front will bring lower clouds along with
showers and scattered thunderstorms starting this evening. Low
level wind shear is expected to develop as southwest winds
increases to around 40 knots at 2000 feet AGL. Clouds and a few
sunny breaks expected Saturday, with scattered thunderstorms,
especially late in the day as a cold front approaches.

This Hazardous Weather Outlook is for north-central and northeast
Wisconsin.

.DAY ONE...Tonight

Some rivers and streams in central and far northeast Wisconsin are
near or above bankfull and running fast. Rainfall and runoff
tonight will cause additional rise of water levels. Be sure to
use extra caution near rivers and streams. Thunderstorms are
possible tonight, but severe weather is not expected.

.DAYS TWO THROUGH SEVEN...Saturday through Friday

Thunderstorms are possible on Saturday and Saturday night. A few
storms on Saturday afternoon and evening could contain damaging
winds and hail. Rainfall and runoff from these storms Saturday and
Saturday night could exacerbate flooding concerns on swollen
rivers and streams.

Additional moderate to heavy rain is possible Tuesday and Tuesday
night as another low pressure system tracks through the western
Great Lakes. Persons near flood prone areas should monitor future
forecasts for possible flooding concerns from additional rainfall.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated tonight.
