FXUS63 KGRB 222007 AFDGRB Area Forecast Discussion National Weather Service Green Bay WI 307 PM CDT Sun Mar 22 2026 Forecast discussion for routine afternoon forecast issuance .KEY MESSAGES... - Some rivers will remain at bankfull or even reach minor flood stage within the next couple days. - Temperatures will moderate the next few days, rising to above normal again from Tuesday to Thursday. - A wintry mix of precipitation is possible during the middle of of the work week, especially Wednesday night into Thursday. - Pleasant weekend expected, with dry conditions and mild temperatures. && .DISCUSSION... Issued at 307 PM CDT Sun Mar 22 2026 Mostly cloudy skies and cool temperatures were observed across the region this afternoon, along with NNE winds gusting to 20 to 30 mph in the Fox Valley and lakeshore areas. Low clouds had partially eroded over central, east central and northeast WI, but were still locked in over the north central part of the state. Fairly strong subsidence is expected across the forecast area later this evening into Monday morning. This should help to break up the low clouds, though they may briefly move back into north central WI overnight into early Monday morning. High pressure will bring widespread clearing and sunshine by Monday afternoon, though high temperatures will only reach normal readings in the lower to middle 40s. High pressure slides east Monday night, setting the stage for a brief period of WAA overnight, followed by a weak cold front sagging into northern WI on Tuesday before stalling out. These features are only expected to bring a small chance of precipitation to far northern WI through Wednesday. Low pressure approaching from the Northern Plains and an associated cold front may bring more widespread mixed precipitation to the region Wednesday night into Thursday. Once this system passes, Canadian high pressure will move into the region for the weekend, bringing mainly dry conditions. After a cooler start to the week, milder temperatures in the 40s and 50s arriive Tuesday through Thursday. A brief cool down arrives after the Thursday cold frontal passage, but above normal temperatures return for the weekend. && .AVIATION...for 18Z TAF Issuance Issued at 1239 PM CDT Sun Mar 22 2026 Low clouds (mostly MVFR) were breaking up over central, northeast and east central WI, but were holding tough over the north central part of the state. Suspect even north central WI will scatter out later this afternoon and evening, but there are indications that MVFR ceilings may move back into that region (including the RHI TAF site) overnight into early Monday. Gusty north winds will subside later this afternoon/early evening, then pick up a little again by mid to late morning on Monday. && .HYDROLOGY... Issued at 307 PM CDT Sun Mar 22 2026 Several rivers have recently risen above bankfull, including the Wisconsin, Spirit, Big Rib, East and Yellow rivers. Forecasts indicate that the Wolf River should reach bankfull on Monday afternoon. At this point, the greatest threat of minor flooding appears to be on the Yellow River near Babcock, as the current river stage is already within a foot of flood stage, and still rising. Although a Flood Warning or two (for minor flooding) may become necessary, no significant flooding is anticipated at this time. && .GRB WATCHES/WARNINGS/ADVISORIES...
