The local office's own words before the first event, 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 the first event at Aug 3, 5:04 AM CST, 1 hour 21 minutes earlier.
Area Forecast Discussion National Weather Service Green Bay WI 604 AM CDT Wed Aug 3 2022 Updated aviation portion for 12Z TAF issuance .SHORT TERM...Today...Tonight...and Thursday Issued at 338 AM CDT Wed Aug 3 2022 Showers and thunderstorms north of a warm front will continue this morning across the region this morning. Although the storms upstream have been strong to severe, our area has been worked over fairly well. Therefore, confidence in these storms maintaining their severity is low. Additional showers and thunderstorms are possible later today into the afternoon as a cold front tracks through the area. Some of these storms could be strong to severe, especially across the Fox Valley east to the lakeshore with MUCAPEs of 2-3 J/g and bulk shear of 30 to 40 knots. The strongest storms would likely produce heavy rain and possibly damaging winds, with marginally severe hail a secondary threat. Localized flooding is also possible, especially across areas that receive several rounds of rain. Conditions will be warm and humid ahead of the cold front with highs in the 80s, as heat index values soar to 90 to 95 across the eastern portion of the cwa. Any remaining rain showers or thunderstorms should quickly exit east of the area this evening, with dry conditions expected for the rest of tonight into Thursday as high pressure builds in across the northern Great Lakes region. Lows tonight are expected to fall into the lower 50s across the north, with lows around 60 across east-central Wisconsin. Highs on Thursday will be cooler; ranging from the upper 70s across the north and highs around 80 across central and east-central Wisconsin away from Lake Michigan. .LONG TERM...Thursday Night Through Tuesday Issued at 338 AM CDT Wed Aug 3 2022 Main focus is on thunderstorms potential this weekend along with warm and humid conditions on Saturday. Otherwise, low-impact weather is expected throughout the long term forecast. Thursday night through Friday night...Starting out clear and quiet as high pressure slowly slides east. Overnight lows will be close to normal in the middle to upper 50s. Staying mostly sunny throughout Friday with highs in the upper 70s (lakeshore) and low 80s elsewhere. A slight uptick in humidity Friday with Tds in the upper 50s and low 60s. More clouds moving in Friday night, particularly across the Northwoods. With southerly flow throughout the night temperatures will be mild and only drop into the 60s. Saturday and Sunday...Somewhat less certain with the timing of any weekend showers and thunderstorms. High confidence that a cold front will track across the area sometime Saturday afternoon into Sunday afternoon, but models differ on timing and whether the front stalls out for a time, and where this would occur. This could be due to the lack of any upper level forcing, as the westerlies will be well north of the Great Lakes this weekend. The GFS is the slowest at bringing the front through, and also shows pwats climbing to 2.00 to 2.25 inches. If this occurs, heavy rain would be a concern with any shower or thunderstorm that develops. The Canadian brings the front through fairly fast Saturday night into Sunday morning, which would be less favorable timing for any severe storms. And the ECMWF is in between, but is starting to trend slower. Increased PoPs a bit from the previous forecast, as showers and storms are likely, but the timing will need refinement. Currently have the highest PoPs from 00Z to 12Z Sunday. Thunderstorms will be possible, but it is too early to fully determine severe potential. Meanwhile, temps and dew points will climb on Saturday, especially across central, east- central, and far northeast WI. Highs are forecast to reach the upper 80s to lower 90s here, with Tds near 70, which could produce some heat index values in the low 90s. Temps will be closer to normal Sunday, with decreasing humidity behind the cold front. Monday through Wednesday...Less certain in details by this point. Some indications a shortwave could break off the main flow and bring a chance of showers early in the week. Overall, this time period looks mainly dry and quiet with surface high pressure lingering over the region and an upper ridge building to the west over the Northern Plains. Temperatures will be near normal. && .AVIATION...for 12Z TAF Issuance Issued at 604 AM CDT Wed Aug 3 2022 Additional showers and thunderstorms are expected today as a cold front sweeps through the region. Conditions could fall to MVFR with the strongest thunderstorms, with damaging winds possible across the eastern TAF sites this afternoon. High pressure will then build in later tonight with VFR conditions and quiet weather expected through Thursday. LLWS will impact the TAF sites early in the TAF period across the eastern TAF sites, but should wane shortly after issuance. Gusty S winds will become SW this morning, then turn NW after the front moves through in the afternoon/early evening. && .GRB WATCHES/WARNINGS/ADVISORIES...
