MPCWhat forecasters said that day
The local office's own words before this severe thunderstorm 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 severe thunderstorm warning went out at Jun 5, 2:36 PM CDT, 3 hours 20 minutes earlier.
Area forecast discussion, Jun 5, 2:36 PM CDT, 3 hours 20 minutes before
Area Forecast Discussion National Weather Service Green Bay WI 236 PM CDT Wed Jun 5 2019 Forecast discussion for routine afternoon forecast issuance .SHORT TERM...Tonight and Thursday Issued at 236 PM CDT Wed Jun 5 2019 Conditions in the short term part of the forecast will be fairly mild. This afternoon, a few showers are possible for the northeast along with a rumble of thunder. Fog and mist likely return tonight, primarily for north-central Wisconsin. By tomorrow morning, high pressure conditions are expected to move into the region, bringing in more clear skies and sunny conditions. The main portion of the front moved into southern Wisconsin this afternoon, which will keep the majority of the instability out of the region. However, easterly flow from the lake will keep an area of convergence in place from approximately Wood to Marinette County. This convergence coupled with diurnal instability, and lingering moisture from the previous night's rain will bring a few scattered showers and possibly a rumble of thunder. However, with virtually no shear or instability, don't anticipate the formation of any strong thunderstorms. Low clouds, fog, and mist are likely to return to the region overnight. The majority of the fog is expected to be in north- central Wisconsin, where the winds will be light and the low level inversion the strongest. Depending on how the rain from the afternoon goes, some patchy fog may extend a bit further east and south as well. There are a few signals for isolated showers again on Tuesday, but stuck with the dry forecast as with previous updates, with the expectation that the easterly flow will keep the area dry. Stuck with a blend of top performing models for temperatures through the period. .LONG TERM...Thursday Night Through Wednesday Issued at 236 PM CDT Wed Jun 5 2019 Fairly tranquil weather expected through the upcoming weekend before the next chance of showers and thunderstorms arrives for the first part of next week. Expect slightly above average temperatures into the weekend before dropping to slightly below average temperatures for the first part of next week. Thursday night through Saturday night: Much of the area will remain under the influence of the western edge of broad high pressure centered over eastern Canada. This will keep dry conditions in place through this time period. Skies will generally become partly cloudy during the afternoon with diurnal heating before clearing overnight. If winds remain light enough, some fog could develop during the overnight hours, especially for locations that received rainfall from the Tuesday night evening. An upper-level ridge will slide across the area Friday and Saturday, which will help keep high temperatures in the upper 70s to low 80s. For comparison, average high temperatures for this time of year are right around the low to mid 70s. Sunday and Monday: A surface low and deepening upper-level trough, digging across the northern Plains, will approach from the west Sunday afternoon. At the same time, the aforementioned high pressure center will slip farther to the east. This will allow moisture to lift northward on increasing southerly flow. These features will shift eastward and cross the area Sunday night into Monday morning. As the associated cold front pass through northeast WI, look for showers and thunderstorms to develop for this time period. The timing of the front will be key to strong to severe thunderstorm potential. Currently, the late afternoon and evening passage of the cold front would allow for enough instability to increase chances for a some strong to possibly severe thunderstorms. Will need to keep an eye on it though as a slower cold front approach would allow for lower instability into the overnight hours. A bit early for details, but it does look like shear values would be in the 20 to 30 kt range with a good portion of that being orthogonal to the front. This again lends some support for stronger thunderstorms. Rest of the extended: Monday afternoon into Monday night, the aforementioned trough axis will be directly overhead during this time period, which will lead to continued chance of scattered showers and possibly a thunderstorm. High temperatures will be kept a bit cooler with most locations in the upper 60s to low 70s. Beyond that time period, timing becomes a bit less certain; however, it does look as if another quick moving surface ridge may slide through the area during the day Tuesday. Highs will likely remain in the upper 60s to low 70s. && .AVIATION...for 18Z TAF Issuance Issued at 101 PM CDT Wed Jun 5 2019 MFVR to VFR conditions are expected across the region today. This will vary through the afternoon and evening as MFVR CIGs develop with afternoon cloud cover, but may scatter out a bit at times. A few showers are possible but thunderstorm development is expected to be greatly limited this afternoon. Tonight, CIGs will drop again and fog development is likely for the western TAF sites, especially northern Wisconsin but may also impact the eastern TAF sites briefly. CIGs will improve quickly towards the end of the TAF period as high pressure builds in to the region. && .GRB WATCHES/WARNINGS/ADVISORIES...
