JGWhat forecasters said that day
The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Green Bay, WI wrote its last area forecast discussion before this river flood warning went out at Apr 16, 7:02 AM CDT, 4 hours 14 minutes earlier. Its key messages:
- -Minor to major flooding is ongoing or forecast to occur on several rivers. Expect many rivers to continue rising into this weekend, with the greatest impacts expected on the Menominee and Wolf Rivers where major or record breaking flooding has been observed. -Severe thunderstorm risk is increasing for Friday evening. Strongest storms are expected across central and north-central WI with all severe hazards possible. -Thunderstorms Friday will produce locally heavy rainfall. If this occurs over the flood sensitive areas of central and east-central WI flood concerns may be exacerbated. -Beginning Sunday a prolonged period of mostly dry weather is expected through at least the middle of next week.
Area forecast discussion, Apr 16, 7:02 AM CDT, 4 hours 14 minutes before
Area Forecast Discussion National Weather Service Green Bay WI 702 AM CDT Thu Apr 16 2026 Updated aviation portion for 12Z TAF issuance .KEY MESSAGES... -Minor to major flooding is ongoing or forecast to occur on several rivers. Expect many rivers to continue rising into this weekend, with the greatest impacts expected on the Menominee and Wolf Rivers where major or record breaking flooding has been observed. -Severe thunderstorm risk is increasing for Friday evening.

If this occurs over the flood sensitive areas of central and east-central WI flood concerns may be exacerbated. -Beginning Sunday a prolonged period of mostly dry weather is expected through at least the middle of next week. && .DISCUSSION... Issued at 217 AM CDT Thu Apr 16 2026 Short Term...Today...Tonight...and Friday Today... Widespread dense fog this morning will begin to dissipate after 8-9 AM with most of the fog cleared out by 10 AM. A few scattered showers may also develop across central and east-central WI early this morning along a stalled boundary that is snaked from Green Bay back toward southwest WI. There may be a few rumbles of thunder, but no stronger storms are expected. Will need to watch precipitation rates as these showers pass over the flood sensitive areas of central and east-central WI, but based on upstream treads don't expect this round of precipitation to exacerbate ongoing flooding. Any lingering precipitation should clear out early this afternoon as a ridge builds in. This will leave dry conditions across the region for the remainder of the day. Severe Thunderstorms and Heavy Rain Potential Friday... Beneath a stout cap a highly unstable airmass will be building during the day Friday. Southerly winds will usher in a tough of 60+ dew points as far north as HWY 8 along with temperatures well into the 70s away from Lake Michigan. A plume of 7-8 C/km mid-level lapse rates associated with an EML will also be overspreading the region at this time. This will result in an increase of surface based instability to around 2000 J/kg late Friday afternoon. Forecast soundings from across central WI also show strong low and deep layer shear across the warm sector with 40-45 kts in the 0-6km layer and 25-30kts in the 0-1km layer. As the cap erodes late in the afternoon isolated discrete super cells may be able to initiate across central WI within an area of subtly convergent surface winds. Any storms that do develop within the warm sector will pose a large hail (1-2") and tornado risk. Stronger and more widespread forcing will then arrive between about 5-6 PM as a sharp cold front and upper level trough push in from the west. With the cloud layer shear oriented nearly parallel to the cold front storms mode will likely transition from discrete cells to a line of storms. As this occurs the severe wind threat will increase as will the QLCS tornado risk. One area of uncertainty is how far east surface based storms will persist. Surface winds will be out of the southeast most of Friday which will keep a stable marine boundary layer across our far eastern counties. Along with the severe threat thunderstorms will also bring a risk for heavy rain. PWATs in increase to near 1" Friday afternoon which in near the 99th percentile for this time of year. HREF 90th percentile hourly precipitation values which should be a good proxy for hourly rainfall rates within the strongest storms are around 0.75-1" per hour. With fast flow through the cloud layer (40-45kts) storms should not sit over one location too long, however, any areas that see multiple storms could see upwards of 1.5-2" of rain Friday evening into early Saturday morning. As has been the case the last few days the greatest risk for flooding will be where there is ongoing river flooding or across parts of central and east-central WI where soils will still be saturated. On the back side of this system much cooler air may result in a brief chance over to snow, mainly across northern WI Saturday morning. However, with the ground thawed don't expect any accumulations. Long Term...Friday Night Through Wednesday Saturday night through Wednesday High pressure will build in across the western Great Lakes region Saturday night, then slowly track east through the central Great Lakes during the early part of next week. The high will provide a much needed reprieve from precipitation for the area. Another cold front is slated to track through the region Monday night or Tuesday as the parent low tracks through southern Canada. This system is expected to track through the region mostly dry as the best moisture and lift will be closer to the upper level support across southern Canada. Therefore, impacts from this upcoming system early next week are expected to be minimal. Mainly dry weather is expected to last through at least the middle part of next week. && .AVIATION...for 12Z TAF Issuance Issued at 701 AM CDT Thu Apr 16 2026 LIFR conditions will linger for another few hours across central and eastern WI as dense fog lingers over the area. Across northern WI clouds and fog have already cleared out as an upper ridge pushes into the region. That clearing trend should continue east across most of the area this morning with nearly all terminals becoming VFR for the rest of the day. The one exception will be MTW where linger marine fog may come onshore at times and create LIFR/IFR conditions. Did include a TEMPO group for the return of patchy fog across east- central WI early Friday, however, confidence in this fog is lower than the last couple of nights. && .HYDROLOGY... Issued at 217 AM CDT Thu Apr 16 2026 Multiple rivers, namely the Wolf, Menominee, and Wisconsin Rivers, continue to read in minor to moderate flood stage, with the Menominee River now in major flood stage due to the additional influence of snow melt from the Upper Peninsula. Home evacuations are ongoing along the Wolf River. High flows and rising water levels have also resulted in several dams being compromised or overtopped. If you live near a river or stream, continue to monitor the latest hydro forecasts and Flood Warnings from the National Weather Service in Green Bay. && .GRB WATCHES/WARNINGS/ADVISORIES...
