550 FXUS63 KGRB 170656 AFDGRB Area Forecast Discussion National Weather Service Green Bay WI 156 AM CDT Wed Jun 17 2026 Forecast discussion for routine morning forecast issuance .KEY MESSAGES... - Showers and storms return today (80-100% chance). A few strong storms with small hail and gusty winds may occur, with the best potential across central to east-central Wisconsin. - Moderate to heavy rainfall today will have a 60-80% chance of exceeding 1 inch of rain. && .DISCUSSION... Issued at 156 AM CDT Wed Jun 17 2026 Today... A strong shortwave will drop into the region today, bringing back widespread rainfall and some embedded thunderstorms. The accompanying surface low will stay stretched across southern Wisconsin and northern Illinois, which will keep the warm front southwards as well. Therefore the strongest severe weather potential will remain focused in these areas, so if you do have travel plans in the direction of Milwaukee and Chicago today stay weather aware. For our neck of the woods, overrunning moisture will bring heavy rain potential into the area. Probabilistic guidance has reduced the probability of exceeding 1 inch slightly, but still remains in the 50-70% chance in a corridor from central to east-central Wisconsin. For severe weather, potential will be somewhat more limited for our area, but a few strong storms will be possible in the mid to late afternoon after the initial showers push through the area. Shear and upper forcing could suffice to produce some hail and damaging winds with any stronger storms, mainly for areas south of Highway 10. Rest of the forecast... Some isolated convection remains in the forecast for Thursday as well, depending largely on surface heating to develop a few showers in the region. While some thunder can`t be ruled out severe weather is not expected. Dry conditions then return for Friday and most of Saturday. The next potential for active weather will arrive early Sunday morning as the next strong system passes to our south. We are again on the northern edge of this system, so early signs do not suggest this will be a period of strong or severe storms for our area. && .AVIATION...for 06Z TAF Issuance Issued at 909 PM CDT Tue Jun 16 2026 VFR flying conditions prevail overnight, with cigs lowering Wednesday morning prior to cold frontal passage. Expect widespread MVFR and even IFR conditions to work their way east during this time, lasting through the end of the TAF period. SCT showers and storms are forecast Wednesday morning through Wednesday evening, with heavy rain, gusty winds, and up to 1" hail possible with any stronger storms during the afternoon. Vsbys may lower into MVFR or IFR territory if heavy rain or a stronger storm were to move over a terminal. However, have withheld mention of thunder in the TAFs this far out due to low confidence in storm coverage and placement. Post-frontal winds ramp up and shift to the southeast Wednesday afternoon, gusting between 20 and 25 knots. Locally higher gusts will be possible with any convection. && .MARINE...

A Small Craft Advisory and Beach Hazards Statement have been issued for the Lake Michigan shoreline as a result.
