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 Milwaukee, WI wrote its last area forecast discussion before this small craft advisory went out at Aug 26, 8:43 PM CDT, 6 hours 44 minutes earlier.
Area forecast discussion, Aug 26, 8:43 PM CDT, 6 hours 44 minutes before
Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 843 PM CDT Sun Aug 26 2018 .UPDATE... Using the SPC Mesoanalysis low level thermal gradient and subtle radar depiction of outflow boundaries, the effective low level boundary likely stretches from about South Milwaukee, east to near Madison, then northeast toward Sauk county. This boundary is of concern as the increasing low level jet impinging on it will likely result in repeated rounds of showers and storms north of this boundary. It will not be stationary and may shift north with time due to the strengthening low level jet. As mentioned in the previous discussion, caution is advised as any strong convection can manipulate that boundary in surprising ways. But, current trends suggest the core of the higher rainfall would focus over the northern half of our forecast area, or roughly north of I-94...give or take a few miles for uncertainty. The southern tier of counties should escape much of the heavy rainfall tonight. The main threat overnight will be heavy rainfall. Some areas north of a Milwaukee to Madison to Baraboo line have received between 1 and 2 inches of rain already this evening. We'll have to keep an eye on trends, but local flooding is a real possibility. Secondarily, strong, damaging straight-line winds are possible in any stronger thunderstorms. The atmosphere is warm to a quite a depth, thus limiting the hail threat. && .MARINE... Scattered thunderstorms are likely through the night, especially north of Milwaukee, and a few could be strong or severe, with gusty winds. Frequent lightning is also expected. Southwest winds will gust to near Small Craft Advisory levels on Monday and Tuesday. There will be additional thunderstorm chances late Monday night and again on Tuesday. A cold front will sweep through the area late Tuesday, with high pressure building into the area on Wednesday and Thursday. && .PREV DISCUSSION... (Issued 546 PM CDT Sun Aug 26 2018) UPDATE... This first round of storms was likely triggered by an old MCV from convection upstream much earlier. This will blow out over the lake by 7 pm. Then we should be mostly quiet into the later evening hours. We then expect another round of storms to develop as the low level jet strengthens into Wisconsin. The concern we have is related to any potential latitudinally oriented old convective boundary with the jet pointing across it. This could set up training storm scenario. It's very difficult to pin point where or if that will happen. For now, the encouraging news is that the more reliable guidance is keeping the core of that heavier rain north of Madison and Milwaukee. But, vigilance is required as convection can and will take on a life of its own and throw a monkey wrench in our expectations. AVIATION(00Z TAFS)... We should remain VFR through the TAF period. The exception will be a period of lowering CIGS to MVFR or even IFR in any stronger thunderstorm activity. Once the storms across the southeast push out over the lake early this evening, we should be generally quiet into the later evening hours. Then another round of showers and storms is expected from about 05-08z Mon...give or take. Once that moves out, we will just have a lingering smaller chance of showers and storms through the remainder of the TAF period. PREV DISCUSSION... (Issued 224 PM CDT Sun Aug 26 2018) SHORT TERM... Rest of this Afternoon through Tonight..Forecast Confidence is Medium... Clusters of thunderstorms are expected to move into the western portions of the forecast area around 4 PM or so. These should then move east with time through the evening hours. Additional development can be expected along various outflow boundaries, making for what will likely be a rather messy evening of convection. Instability is quite high across the area, so once convection does develop, there will be an associated wind gust threat. There will also be a threat for large hail, though this will be mitigated somewhat by high freezing levels. The tornado threat is low but non-zero, with eastward surging line segments and boundary interactions as the most likely features from which to see a brief tornado. Additional thunderstorm development is then expected late this evening into the overnight as the low level jet noses into the area. The most widespread activity late tonight should be across central Wisconsin, though a few scattered storms may develop across the southern portion of the state. Along with the threat for severe weather, heavy rain and flooding remain a significant concern. With PWATs in excess of 2 inches, lots of CAPE and high freezing levels, rainfall rates will be very high with any convection this afternoon. Even with progressive movement, today's storms could easily produce a quick 1-2" of rain in less than an hour. The flood and flash flood threat will be greatest across the central and southern forecast area, where soils are most saturated from last week's rainfall. Monday through Tuesday Morning - Confidence...Medium Another hot and humid day is on tap for Monday as southwesterly flow continues across southern Wisconsin. Appears as though there will be some leftover showers extending from central Lake Michigan southwest through southwest Wisconsin Monday morning downstream from an elongated mid level shortwave trough. Once this convection clears by late morning, temperatures should quickly rise while surface dew points linger in the low to mid 70s. Heat indices max out around the mid 90s in the afternoon, so a heat advisory is not looking likely at this point. Convection should then initiate in northwest Wisconsin Monday afternoon and push east-southeast into the low level moisture transport which will be nosing up into northern Wisconsin. The main question is with how far south that MCS makes it and whether it just stays up in northern WI along the strengthening LLJ. Given the strong low level winds, unstable air mass feeding into it (~2000 J/kg 0-3km MUCAPE) and decent 0-6km effective shear of 30-40kts, can not rule out the chance of severe thunderstorms for southern Wisconsin, mainly on Monday night. Damaging winds, large hail and heavy rainfall would be the main concerns. Precipitable water will be up around 2", so some localized flash flooding is certainly possible if the MCS holds up in any areas. LONG TERM... Tuesday through Wednesday Night - Confidence...Medium Fairly consistent idea between the 26.12z guidance in bringing the cold front into the region on Tuesday but each model has it's own idea of where the convection will initiate. With the ingredients for severe weather will still be there with decent mid level winds and an unstable air mass in place ahead of the front. Just a matter of what the previous night's convection does and where boundaries set up. What happens on Wednesday is a bit up in the air as the previous runs of the NAM/GFS/ECMWF had the front well to the east but now the 26.12z NAM/ECMWF bring another shortwave through the mid level flow and bring another round of convection into the region. Thursday through Saturday - Confidence...Medium to Low With ridging in place for Thursday and Friday, it appears as though there will be a few dry and seasonal days in there before the front lifts back to the north by next weekend. Saturday appears to be the next best chance for storms with the front again cleared by Sunday. AVIATION(18Z TAFS)... Thunderstorms are expected to affect the area this evening. There will likely be a prolonged period of scattered activity from late afternoon or early evening into the mid to late evening hours. Did indicate via TEMPO groups the most likely timeframe for thunderstorm impacts, which look to be during the early to mid evening hours. Outside of thunderstorm impacts, winds will start to increase from the southwest later tonight and tomorrow. A few gusts around 20 knots are possible tomorrow mid day through the afternoon. MARINE... Areas of Dense Fog will remain possible into early evening, especially north of North Point Light. Fog will be most widespread near open waters. Scattered thunderstorms are likely this evening, and a few could be strong or severe, with gusty winds. Frequent lightning is also expected. Southwest winds will gust to near Small Craft Advisory levels on Monday and Tuesday. There will be additional thunderstorm chances late Monday night and again on Tuesday. A cold front will sweep through the area late Tuesday, with high pressure building into the area on Wednesday and Thursday. && .MKX WATCHES/WARNINGS/ADVISORIES... WI...None.
