Area forecast discussion, Aug 22, 2:50 PM CDT, 24 minutes before
Area Forecast Discussion National Weather Service Green Bay WI 250 PM CDT Tue Aug 22 2023 Forecast discussion for routine afternoon forecast issuance .SHORT TERM...Tonight and Wednesday Issued at 250 PM CDT Tue Aug 22 2023 The latest RAP analysis and satellite/radar imagery show elevated showers and thunderstorms slowly exiting northeast Wisconsin early this afternoon. Meanwhile, temperatures have been slow to rise over many parts of northeast Wisconsin in part due to southeast winds, ample cloud cover, and positioned northeast of a warm front. This warm front was roughly located north of Minneapolis to the Wisconsin Dells to Madison at 19z. As this warm front surges northward, thunderstorm chances and excessive heat are the main forecast concerns through Wednesday. Tonight...The warm front will progress northeast and into far northern and northeast WI by 7 am Wednesday. Like last night, a 40+ kt low level jet is expected to develop and initiate convection, this time over the central Upper Peninsula from late evening into the overnight. Cloud layer flow will remain out of the northwest which would track any storms over far northern Door county. Small hail and locally heavy rain will be possible. The rest of the region should see mostly clear to partly cloudy skies and warmer conditions. Lows ranging from near 60 degrees in the northwoods to around 70 at Marshfield and Wisconsin Rapids. Wednesday...The warm front will stall over far northern Wisconsin for much of the day, placing the majority of the region in the warm sector. Under mostly clear skies, should have ample sunshine for very warm temps to occur before winds shift to the north late in the afternoon. Taking an average of 925mb temps puts highs in the mid to upper 90s over central and east-central WI. Combined with dewpoints in the low to mid 70s, heat indices of 100 too 110 look likely. Forecast highs have increased a degree or two in this forecast cycle, so will expand the excessive heat warning and heat advisory. The expiration time is not ideal, but matches neighboring offices headlines, and it can be canceled early. .LONG TERM...Wednesday Night Through Tuesday Issued at 250 PM CDT Tue Aug 22 2023 Warm and humid weather is likely Wednesday night as dewpoints remain in the 60s. Thursday will not be as hot as Wednesday, but will still be warm and humid over all but the north despite a northeast wind. An upper trough and surface cold front will move across the area Friday and bring a chance of showers and thunderstorms. There may be enough instability to get some strong or severe storms in the north where directional and speed shear are maximized. Cooler and drier weather will return for Saturday and Sunday as a large surface high moves in from central Canada. There may be enough of a northeast wind Saturday for small craft advisory conditions on the lake and bay. && .AVIATION...for 18Z TAF Issuance Issued at 1228 PM CDT Tue Aug 22 2023 Scattered showers and maybe a a storm or two will continue to slowly move northeast over far northeast Wisconsin early this afternoon before exiting. Additional storms are expected to fire over the Upper Peninsula which will slide southeast and could impact the northern Door Peninsula late tonight. Otherwise, as a warm front surges northeast across the area, MVFR and low end VFR ceilings will gradually retreat northward. Clearing skies will occur tonight, except for parts of far northeast Wisconsin. Low level wind shear will likely impact central WI late tonight into early Thursday morning. Southeast winds today will become south on Thursday morning with some gustiness up to 20 kts possible. && .GRB WATCHES/WARNINGS/ADVISORIES... Heat Advisory from 10 AM to 9 PM CDT Wednesday for WIZ020-030- 031-037>040-049-050-074. Beach Hazards Statement from Wednesday morning through Wednesday evening for WIZ022-040-050.
