What forecasters said that day
The local office's own words before this small craft advisory 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 small craft advisory went out at Aug 26, 6:13 AM CDT, 4 hours 2 minutes earlier.
Area forecast discussion, Aug 26, 6:13 AM CDT, 4 hours 2 minutes before
Area Forecast Discussion National Weather Service Green Bay WI 613 AM CDT Sun Aug 26 2018 Updated aviation portion for 12Z TAF issuance .SHORT TERM...Today...Tonight...and Monday Issued at 330 AM CDT Sun Aug 26 2018 Despite several sites reporting visibilities near 1/4 of a mile early this morning, area webcams and in situ observations here in GRB indicate the fog this morning is fairly shallow and transient. In fact several sites keep bouncing around between various visibilities, further backing up this assumption. Therefore will hold off on issuing a Dense Fog Advisory this morning and handle the current conditions with an SPS statement. After a foggy start to the morning, temperatures will warm into the 80s across much of the region as a warm front lifts north across the western Great Lakes. Across the north highs will generally be around 80, with lower to middle 80s across central and east-central Wisconsin away from the lake. A very moist unstable atmosphere will be in place this afternoon and tonight as a mid level PV anomaly tracks through the western Great Lakes with the low level jet increasing to around 50 knots in the vicinity of a surface warm front. Instability will increase to 3 to 4 J/g this afternoon and this evening, with 40 to 50 knots of bulk shear and PWATs around 2 inches. These parameters and model soundings indicate that strong to severe storms are on the table along with torrential rains. These storms could produce damaging winds, large hail and localized flooding. Mesoscale models indicate the main storm mode this afternoon and tonight appears to be multi-cell clusters or even a QLCS. Some of these storms from the complex may be ongoing early Monday morning as the warm front lifts north across the UP. This will allow temperatures to rise well into the 80s across the entire area during the afternoon hours. The warm front will be the focus for additional showers and thunderstorms Monday afternoon, mainly across north-central Wisconsin in close proximity to the front. Given similar severe weather parameters and PWATs, the severe weather and flooding threat will be on par with today. However the greatest threat will be across north-central Monday afternoon as the warm front begins to push south as a cold front late in the period. .LONG TERM...Monday Night Through Saturday Issued at 330 AM CDT Sun Aug 26 2018 The main forecast concerns are severe storms and flooding potential during the early part of the long term. A mid level short wave is forecast to pass through Wisconsin on Monday night. Models had MUCAPE values near or even in excess of 3,000 J/kg, 30 to 50 knots of deep layer shear, and an 850 mb jet of 50+ knots. In addition to that, PWATs around 2 inches are also forecast. An approaching cold front looks to be the focus for storms, and any outflow boundaries or other boundaries in the area would also help to generate convection. The presence of significant instability, shear, abundant moisture and a lifting mechanism should be enough for a damaging wind threat. Flooding may also be an issue depending upon how much rain falls tonight and whether the same areas are impacted by heavy rainfall Monday night. A flood watch may be needed if there is significant rainfall with tonight's convection. The cold front is not expected to make much progress into the state before it stalls across northern Wisconsin on Monday night. As a result, a third round of storms is possible Tuesday until the front clears the area. If there is enough time to stabilize on Tuesday, some storms could be strong or severe. There should be a period of dry weather from Wednesday afternoon through Thursday night before the next chance for storms arrives Friday into Saturday. Expect above normal temperatures on Tuesday to give way to near or slightly below normal readings Tuesday night through Thursday night before a warming trend brings highs mostly in the mid to upper 70s for Saturday. && .AVIATION...for 12Z TAF Issuance Issued at 613 AM CDT Sun Aug 26 2018 Areas of fog (locally dense) and low stratus will continue for another hour or so this morning, resulting in IFR/LIFR conditions in most places through 13z-14z. Once the fog lifts, VFR conditions should prevail from mid-morning through mid-afternoon. An upper level disturbance and approaching warm front will bring showers and thunderstorms to the region late this afternoon and tonight, with the potential for strong gusty winds, very heavy rainfall and associated IFR conditions. LLWS looks to develop across the eastern TAF sites this evening and continue through the overnight hours as the low level jet increases. Further west conditions were too borderline so continued to leave out of these sites. && .MARINE... Issued at 330 AM CDT Sun Aug 26 2018 Southerly winds will increase late tonight into Monday as a low pressure system approaches from the west, turning southwesterly Monday night as a cold front moves through the area. Winds and waves will likely approach or exceed Small Craft Advisory criteria, especially across the Lake Michigan nearshore waters late tonight through Monday night. Given the timing and uncertainty regarding conditions tonight will hold off on issuing any headlines with this issuance. However a Small Craft Advisory will likely be needed at some point, especially for Monday and Monday night. In addition to the hazard to boaters, a Beach Hazards Statement may be needed on Monday for beaches along Lake Michigan due to the aforementioned high winds and waves, producing an increased risk for rip currents. && .GRB WATCHES/WARNINGS/ADVISORIES...

The primary concerns with these storms are damaging winds and large hail. Torrential rainfall could lead to localized flooding. Areas of dense fog could make travel hazardous in some areas early today. .DAYS TWO THROUGH SEVEN...Monday through Saturday There is a slight risk of severe storms across the area Monday into Monday night. The primary concerns with these storms are damaging winds and large hail. Torrential rainfall could lead to flooding, especially in locations that receive heavy rain with tonight's storms. Large waves may result in dangerous currents and hazardous swimming conditions on Lake Michigan beaches on Monday. There is a marginal risk of severe storms, mainly in central and east-central Wisconsin Tuesday afternoon and evening. Damaging winds and large hail are the main concerns with these storms. Heavy rainfall and flooding remain a concern with the storms. There is another chance for thunderstorms Friday into the weekend, but is too early to determine their severe potential. .SPOTTER INFORMATION STATEMENT...
