Area Forecast Discussion
National Weather Service Green Bay WI
1041 PM CDT SAT JUN 4 2016

Updated aviation portion for 06Z TAF issuance

.UPDATE...
Issued at 913 PM CDT Sat Jun 4 2016

Intensity and coverage of the showers and storms have lowered the
last few hours. Still anticipate scattered showers and perhaps an
isolate storm will linger over northeast wisconsin as upper
heights continue to fall as the deep upper trough works into the
area. Meso data shows some lingering weak mu capes across
northeast wisconsin as well. As a result...expect shower activity
to very slowly diminish overnight with loss of heating.
&&

.SHORT TERM...Tonight and Sunday
Issued at 257 PM CDT Sat Jun 4 2016

Currently monitoring a marginal severe weather threat over central
WI, where partial clearing has occurred, CAPE has increased to
800-1000 j/kg, and a warm frontal boundary is situated nearby.
Right now, it appears that hail and heavy rainfall will be the
main threats, but the non-supercell tornado parameter is
highlighting a threat of funnel clouds/weak tornadoes in our far
western and southwest counties. Have noticed some weak rotation
with a few cells in western WI, but haven't seen any reports of
funnel clouds from upstream offices.

The convective activity will peak late this afternoon and early
evening, especially over our western and southern counties.
Despite the passage of the upper trof overnight, a general
decrease in shower activity is anticipated due to waning
instability. Have pulled the mention of thunder after 03z/Sun.
After a general lull in the pcpn late tonight into Sunday morning,
expect sct showers and isolated tstms to redevelop in the
afternoon as a short-wave trof moves through northern WI.
Instability should be fairly weak, so not expecting any strong
storms.

Used a blend of the better performing guidance sets for
temperatures. Lows tonight should be in the upper 40s to middle
50s, with highs on Sunday in the upper 60s to middle 70s.

.LONG TERM...Sunday Night Through Saturday
Issued at 257 PM CDT Sat Jun 4 2016

Northeast Wisconsin will remain in a relatively cool pattern
through the upcoming work week as a broad upper-level low
pressure trough over the eastern half of North America slowly
transitions east. There is a chance for showers and thunderstorms
off and on through the week. A strong upper-level high pressure
ridge will expand into the Midwest by the end of the week and
temperatures will warm at that time.
&&

.AVIATION...for 06Z TAF Issuance
Issued at 936 PM CDT Sat Jun 4 2016

An upper low system with frontal system settling over
the state overnight will continue to produce isolated to scattered
showers. Patchy mvfr/ifr cigs will become more widespread
overnight due to a moist boundary and light winds. Patchy to
areas of fog will also likely develop where skies can clear for a
few hours. Conditions expected to improve later sunday morning as
westerly winds increase.

.GRB WATCHES/WARNINGS/ADVISORIES...
NONE.
