Area forecast discussion, Sep 6, 10:30 PM CDT, 3 hours 14 minutes before
Area Forecast Discussion National Weather Service Green Bay WI 1030 PM CDT Sun Sep 6 2026 Updated aviation portion for 06Z TAF issuance .KEY MESSAGES... - Dry conditions for the rest of the Labor Day weekend. Patchy fog is possible late tonight into Monday morning. - Next chance of rain and storms (60-80%) late Monday night through late Tuesday night. Strong storms are possible Tuesday and Tuesday night. - Gusty winds and high waves Tuesday through Wednesday will likely result in hazardous conditions for small craft and an increased risk of rip currents at Lake Michigan beaches. - Above normal temperatures continue into next weekend. && .DISCUSSION... Issued at 214 PM CDT Sun Sep 6 2026 Remainder of Labor Day Weekend...The prevailing high pressure and upper-level ridging will keep dry conditions in place for this forecast period. The only minor impact would be the potential for patchy fog to develop late tonight into Monday morning, but the potential for dense fog is low. Temperatures will remain above normal with overnight lows in the mid 50s to low 60s, and highs on Labor Day ranging from the upper 70s to low 80s. Late Monday through Late Tuesday Precip/Storm Potential...The ridge and high pressure will gradually depart late Monday as return flow sets up ahead of an approaching system/cold front. Ahead of the front, a southwesterly LLJ (35-45 kts) and increasing WAA will aid in rain showers and a few elevated storms starting late Monday night in north-central WI and spreading/moving east/southeast across the remainder of the forecast area through late Tuesday night. It appears the majority of the precipitation will be pre-frontal. Given the greater instability, stronger sheer, steeper mid-level lapse rates will be associated with the cold front, this leads to a conditional risk of strong/severe storms sometime Tuesday evening/night, but will depend on frontal timing and how much cloud cover will be around from the morning precipitation. There will also be an increased risk of heavy rainfall/downpours given PWATs will be around 1.75-2.00 inches throughout the period. In addition to the precip/storm potential, breezy south winds are expected on Tuesday gusting to 20-25 mph, followed by westerly winds on Wednesday gusting to 30-35 mph. Rest of the forecast...Thursday and Friday are expected to be dry with the next chance of showers/storms on Friday evening into Saturday. Near normal temperatures are anticipated on Thursday, but will rise above normal again Friday into Saturday. && .AVIATION...for 06Z TAF Issuance Issued at 1030 PM CDT Sun Sep 6 2026 Middle to high clouds will continue to pass over the region at times through tomorrow, resulting in VFR flying conditions prevailing through the TAF period. Only exception will be with any reductions in vsbys due to patchy fog development after midnight tonight, though confidence was not high enough to include in the TAF. Vsbys should still remain MVFR even if fog were to directly impact a terminal. Next chances for rain then arrive from the west toward the tail end of the TAF period (just beyond 06Z Tuesday) for most locations, with the potential exception of RHI. After becoming light and variable overnight, winds shift to the south late Monday morning, increasing to around 5 to 10 knots during the afternoon. && .MARINE... Issued at 214 PM CDT Sun Sep 6 2026 Southerly winds will increase on Tuesday and result in increased waves on the nearshore waters of Lake Michigan and Green Bay. Winds will veer west on Wednesday and remain gusty. During these periods, conditions will likely be hazardous to small craft. There will also be an increased risk of rip currents mainly Tuesday into Wednesday morning, or until winds turn offshore. Small Craft Advisories and Beach Hazards Statements will be needed. && .GRB WATCHES/WARNINGS/ADVISORIES... None. && DISCUSSION.....Kruk AVIATION.......Goodin MARINE.........Kruk
