Area Forecast Discussion National Weather Service Green Bay WI 1130 PM CDT Tue Apr 16 2024 Updated aviation portion for 06Z TAF issuance .KEY MESSAGES... - Elevated fire weather conditions will persist into early this evening across northern Wisconsin due to low relative humidity and gusty east winds. - Showers and a few embedded thunderstorms are expected tonight into Wednesday. Widespread severe weather is not expected, but some of stronger showers and storms could produce a brief period of wind gusts over 50 mph. Small hail is possible with some of the stronger thunderstorms. Locally heavy rainfall is possible. - Strong east to southeast winds are expected this afternoon into tonight, with gusts of 30 to 50 mph. The strongest gusts are anticipated across central, east-central, and portions of north- central Wisconsin where a Wind Advisory has been issued. - The strong easterly winds may produce some localized blowing dust across southern Wood and western Waushara counties, especially on Highway 54 in Wood County and Interstate 39 between Plover and Coloma. Once the rain arrives by early evening, the risk of blowing dust will come to an end. && .DISCUSSION... Issued at 315 PM CDT Tue Apr 16 2024 Short Term...Tonight and Wednesday Another day with elevated fire conditions across the north due to low humidly readings in the 15 to 30 percent range along with increasing winds. The strong winds were also causing areas of blowing dust across southern Wood and western Waushara counties, especially on Highway 54 and on Interstate 39 between Plover and Coloma. Any blowing dust will come to an end once the rain arrives. The band of showers and thunderstorms will move into central Wisconsin late this afternoon and across the Fox Valley and lakeshore early this evening. Bufkit soundings indicated between 300 and 600 J/KG of CAPE. The main story will be the strong winds off the deck. Any shower or storm this evening could produce a wind gust over 50 mph. The first band of showers and storms will move into far northeast Wisconsin towards midnight. There will be a break or lull in the shower and storm activity with subsidence behind the first cluster of storms. The next round of steadier showers and storms arrives late tonight into early Wednesday morning, with the greatest focus across central Wisconsin. For the Wind Advisory, moved up the end time across central Wisconsin as winds slacken off there first. I kept the end time across east-central Wisconsin due to strong winds off the lake will continue longer into the night. It is possible that the advisory may be cancelled early. Showers and a few storms will continue Wednesday morning with a decrease in the activity during the afternoon. High temperatures will range from around 50 north and in the lower 60s across central and east- central Wisconsin. Long Term...Wednesday Night Through Tuesday Precipitation...A few rain showers may linger into Wednesday night as a low pressure system shifts off to the northeast, but with dry air at the mid and upper levels progged to pushed over the region expect most of the area to turn dry overnight Wednesday into Thursday. Models are in decent agreement with a disturbance supported by an right rear jet quad moving south of the region Thursday afternoon/evening that may bring a round of rain to central and east-central WI. There is more uncertainty with the potential for rain across northern WI during this time as some models are showing the development of a surface low over the UP creating a convergence boundary across northern WI, while other models don't have this feature at this time. The region will remain in the cyclonic flow of a system slowing moving into Quebec Friday. An area of cold air advection may bring a period of mixed precipitation through Friday evening, with forecast soundings showing a sufficiently cold profile for the possibility of all snow across northern WI, however, with the warm ground any accumulations should be minimal. A ridge of high pressure is then expected to for this weekend returning dry conditions to the region. Next chance for any precipitation then looks to come early next week, but there is not enough of a model consensus to dig too much into the details at this time. Temperatures... Temperatures on Thursday will be dependent an any precipitation that forms and if a surface boundary develops, for now have high temperatures a few degrees above normal with most areas in the middle to upper 50s. The cold air advection will bring cooler temperatures Friday and Saturday with highs expected to be a few degrees below normal. Highs in the low 40s to low 50s are expected each day. As surface winds back and become southwesterly Sunday into Monday slightly above normal temperatures are expected to return. && .AVIATION...for 06Z TAF Issuance Issued at 1130 PM CDT Tue Apr 16 2024 Flying conditions will continue to fall into the MVFR/IFR categories late this evening and overnight as a strong low pressure system tracks towards the state. The first large area of showers and isolated/scattered storms will continue to spread across the area late this evening. A lull in the showers/storms is expected for a time overnight, then another wave will arrive Wednesday morning as the low moves across northeast WI. A few LIFR conditions are possible overnight into Wednesday morning. East winds of 15-30 kts, with a period of lighter more variable winds at times, will continue this evening then slowly decrease overnight into Wednesday morning as the low moves overhead. Winds will shift to the west by Wednesday evening and gust up to 30 kts. Locally higher gusts are possible in/around any heavier showers/storm. LLWS is expected as winds at 2000 ft remain at 45-60 kts for much of the night. LLWS will end Wednesday morning as the winds aloft decrease. Marginal LLWS will be possible Wednesday evening as winds at 2000 ft increase to around 40 kts, but surface gusts could limit the amount of shear. && .MARINE... Issued at 315 PM CDT Tue Apr 16 2024 A Gale Warning remains in effect for tonight. Easterly winds have been increasing this afternoon and will reach gale force tonight.
