Area Forecast Discussion National Weather Service Green Bay WI 303 PM CDT Tue Jun 16 2026 Forecast discussion for routine afternoon forecast issuance .KEY MESSAGES... - Showers and storms end by evening. Most storms will produce small hail and gusty winds. An isolated storm could produce quarter sized hail over eastern WI. - Another round of showers and storms are expected for Wednesday (80-100% chance). A few strong storms with small hail and gusty winds may occur. Moderate to heavy rainfall will have a 60-80% chance of exceeding 1 inch of rain. - Below average temperatures in the 60s and 70s through the week. && .DISCUSSION... Issued at 303 PM CDT Tue Jun 16 2026 Active weather continues through late this week. Temperatures will remain below normal. Into this evening...Compact, tightly wrapped up shortwave trough crosses the region. Instability has built sufficiently to result in strong to severe storms early this afternoon with 0.5 inch to 1.0 inch hail, especially with such low freezing levels. Lack of shear well under 20 kts means main storm mode will be pulse type. Showers and storms will exit eastern WI after 6-7p. Wednesday... Another, stronger shortwave drops towards the region on Wednesday, bringing another round of showers and storms. The track of the accompanying surface low is expected to remain over southern Wisconsin which should keep warm front and more unstable air south of the area, and greatly limit the overall severe potential. That said, some overrunning moisture from the surface warm front combined with some surface heating and sufficient shear will still support at least embedded storms. Best potential for any stronger storms will be from central to east-central Wisconsin, mainly south of highway 10. Heavy rainfall will also be possible with any convection. There is a Marginal Risk of Excessive Rainfall stretching across central to east-central Wisconsin and southwards as well. Rest of the forecast period...Another brief round of scattered (20-30% chance) showers will be possible on Thursday, driven primarily by strong surface heating. Convective support will be relatively minimal, so expect impacts from any scattered showers to be minimal. After this, the only chance for more widespread active weather would be Saturday night into Sunday, when another larger system enters western Great Lakes. Greatest risk for rain appears to be setting up for Sunday instead of Saturday. && .AVIATION...for 18Z TAF Issuance Issued at 1232 PM CDT Tue Jun 16 2026 Numerous showers with scattered thunderstorms will prevail through the afternoon as sfc low crosses WI. Greatest instability is over east-central WI and this is where hail the size of quarters and wind gusts over 30 kts could occur this afternoon. Mainly VFR cigs are expected, though pockets of MVFR are possible, especially over central WI. Showers end by this evening, with the next round of showers and possible thunder arriving late Wednesday morning. && .MARINE... Issued at 303 PM CDT Tue Jun 16 2026 S to SE winds increase Wednesday afternoon before shifting to NE as sfc low passes by to the south. Waves build sufficiently enough that a Small Craft Advisory and Beach Hazards Statements will eventually be needed. The higher waves will linger into Thursday morning, before winds shift offshore to the NW. && .GRB WATCHES/WARNINGS/ADVISORIES... None. && DISCUSSION.....JLA AVIATION.......JLA MARINE.........JLA
