Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 1227 PM CDT Sun Aug 28 2022 .UPDATE... (Issued 1226 PM CDT Sun Aug 28 2022) The MCV and associated strong storms over ern IA will spread newd across srn WI this afternoon. MLCAPE increasing to 1500 J/KG and mdt deep layer shear will likely be enough for a few SVR storms. SPC added a 2 percent Tor prob given modest low level wind shear. Will have to watch for any mesovortex development where the developing line of storms is perpendicular to the swly 0-3 KM shear around 30 kts, but supercellular development is possible as well. The showers and storms will end over ern WI early this evening but another line of storms will approach the nw half of the CWA during the early morning hours. There is uncertainty whether it can hold together out of MN into WI given that the upper dynamics remain to the north. However decent moisture transport will be feeding the line. Will plan on the line moving into the nw CWA but becoming more scattered with time, possibly lingering into the morning daylight hours. The cold front will then gradually pass on Mon with likely storm development mostly to the east and south of srn WI. Very warm and humid conditions are expected with cooling and drying by Tue. Gehring && .SHORT TERM... (Issued 357 AM CDT Sun Aug 28 2022) Today through Monday: A weak shortwave will roll through today, while the low level jet leans more into southern Wisconsin. Will also see the deeper moisture surge into the area. These ingredients will push upstream showers and storms into the forecast area this morning, with continued chances in the afternoon into the evening as moisture and instability lingers. Still looks like highs will struggle up to around 80 given all the clouds, though a few pokes of sunshine may allow for some low 80s. The main surface low will pass by to the north Monday, dragging a cold front through southern Wisconsin. More storm chances are expected later tonight into Monday as the front approaches. Still looks like the front may come through earlier in the day, which would limit the window of time for any strong/severe storms before the front exits. Looking more and more like that threat will be to the east/southeast of the forecast area. Temps will probably be a bit warmer Monday, especially in the east with more time for heating before the front moves through. DDV && .LONG TERM... (Issued 357 AM CDT Sun Aug 28 2022) Tuesday through Saturday: High pressure will begin to move into the area Tuesday, eventually moving overhead by Thursday and then lingering into the weekend. With a somewhat cooler and drier northwest flow aloft during this period, expecting temps to run a bit below normal Tue through Fri. Lower humidity, breezy conditions, and cooler overnight lows may make it feel just a touch like fall is around the corner. Southerly winds will then likely bring a return of highs in the 80s by the weekend. DDV && .AVIATION... (Issued 1226 PM CDT Sun Aug 28 2022) The daytime heating and high humidity is leading to bkn010-020 stratocumulus over south central WI and portions of se WI early this afternoon. A band of showers and strong storms will then move from sw to ne across srn WI during the afternoon hours with very limited Cigs and Vsbys within and around the storms. Afterward, the stratus is expected to only linger for 2-3 hours with VFR conditions returning. Local MVFR Cigs may form once again during the early morning hours of Mon with additional chances for showers and storms especially over south central WI. These conditions will linger into the morning daylight hours, but overall VFR conditions will prevail on Mon. Gehring && .MARINE... (Issued 357 AM CDT Sun Aug 28 2022) Winds will be breezy at times today through the early parts of the week as low pressure moves by well north of the lake. There will also be a chance for thunderstorms today into Monday as the low and associated cold front pass through the region. Lighter winds and lower waves are expected for mid to later parts the week as high pressure moves into the area. DDV && .MKX WATCHES/WARNINGS/ADVISORIES... WI...None.
