538 FXUS63 KGRB 200729 AFDGRB Area Forecast Discussion National Weather Service Green Bay WI 229 AM CDT Sat Jun 20 2026 Forecast discussion for routine morning forecast issuance .KEY MESSAGES... - Scattered showers are expected this afternoon. Some rumbles of thunder will also be possible at times, mainly across far northeast Wisconsin, including Door County. - Next chance for widespread rainfall will be the middle of next week. - Near to below normal temperatures and comfortable humidity will prevail through next week. && .DISCUSSION... Issued at 229 AM CDT Sat Jun 20 2026 Active Weather Potential... A few showers may yet linger over northeastern Wisconsin around sunrise but clearing skies are expected to quickly work their way into the region by noon. The dry conditions will be short-lived as the next shortwave crosses the region over the afternoon, capitalizing on the lingering low- level moisture and instability to develop scattered showers across the area. A few of these showers may also includes some rumbles of thunder, with the best potential for any storms being across far northeastern Wisconsin. No severe weather is expected. Sunday, a more potent system will pass well south of the region. Slight variations on the track of this system have changed the northern most extent of precipitation, which has once again made for a dry forecast for our area. If this system begins to track a little further north once again, some showers may again work their way into the forecast. Finally, active weather continues next week as northwesterly flow persists across the region. Another round of widespread showers are in the forecast for sometime Tuesday night into Wednesday. Long range guidance does support some storm development during this time as well, but its too early to assess potential for severe weather. Temperatures... Without any major airmass changes, temperatures remain fairly similar through the forecast period, although there is a slow warming trend through the end of next week. High temperatures are generally in the 70s but a few areas may see the lower 80s again by Friday. && .AVIATION...for 06Z TAF Issuance Issued at 1009 PM CDT Fri Jun 19 2026 As a cold front exits eastern WI early overnight, the threat of storms will diminish at GRB/ATW/MTW, but light showers will likely continue through 08-09Z. As the rain ends overnight, confidence remains low with the flight conditions as guidance generally disagrees in the development of low clouds and/or fog. Considering winds and climatology, continue to show a mention of low end MVFR ceilings at AUW/CWA/RHI late tonight into Sat morning. With heat of the day, these ceilings should rise to VFR by late morning or early afternoon. Scattered showers will develop again on Saturday afternoon, but confidence of coverage near the TAF sites is low enough to forego a prob30 group. Then clearing conditions are expected after 00-02Z Sun. && .GRB WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION.....Uhlmann AVIATION.......MPC
