\ud83c\udf29\ufe0f Active start to the week in southern Wisconsin<\/strong><\/p>\n A moist, unstable air mass<\/strong> lingers across southern Wisconsin<\/strong> this Monday<\/strong>, fueling scattered showers<\/strong> and isolated thunderstorms<\/strong>, primarily west of Madison<\/strong>. These disturbances are being driven by a shortwave trough<\/strong> combined with weak warm air advection<\/strong>\u2014two ingredients that continue to stir up evening convection<\/strong>. While some showers may weaken tonight, clouds will persist<\/strong> across much of the region.<\/p>\n Overnight<\/strong>, another batch of light to moderate rainfall<\/strong>, with embedded thunderstorms<\/strong>, could redevelop after midnight and carry into early Monday morning<\/strong>, especially west of Madison<\/strong>. Afternoon skies may break at times, boosting inland temperatures<\/strong> into the mid-80s\u00b0F (29\u201330\u00b0C)<\/strong>, while locations along Lake Michigan<\/strong> stay significantly cooler due to an onshore southeast breeze<\/strong>.<\/p>\n <\/p>\n \u26c8\ufe0f Monday night into Tuesday: Storms gather strength<\/strong><\/p>\n By late Monday night<\/strong>, models hint at a decaying mesoscale convective system (MCS)<\/strong> sweeping across northwestern Wisconsin<\/strong>. Although instability and shear remain modest<\/strong>, there’s still enough cold pool support<\/strong> to maintain some organized convection<\/strong> through the night. As a cold front approaches on Tuesday<\/strong>, it\u2019s expected to stall near the Illinois border<\/strong>, setting the stage for multiple rounds of rain and thunderstorms<\/strong>.<\/p>\n The Tuesday afternoon into Wednesday<\/strong> period looks particularly volatile, as upper-level energy<\/strong> enhances thunderstorm development<\/strong>. Some storms could turn strong<\/strong>, capable of producing gusty winds, heavy downpours<\/strong>, and frequent lightning<\/strong>. Rainfall during this time may lead to localized flooding<\/strong>, especially in low-lying and poor-drainage areas.<\/p>\n <\/p>\n \ud83c\udf27\ufe0f Midweek: Surface low deepens, widespread storms<\/strong><\/p>\n By midweek<\/strong>, a developing surface low pressure system<\/strong> traveling along the stalled boundary<\/strong> will interact with upper-level support to generate repeated rounds of rain<\/strong>. Expect moderate to heavy rainfall<\/strong> across southern Wisconsin<\/strong>, particularly along and south of Interstate 94<\/strong>. There is a growing concern for river rises<\/strong> and flood-prone areas<\/strong>, especially if storms \u201ctrain\u201d over the same locations.<\/p>\n Forecast models remain in moderate agreement<\/strong>, indicating stronger thunderstorms<\/strong> embedded within the broader rain shield<\/strong>, particularly late Tuesday into Wednesday night. Areas around Janesville<\/strong>, Beloit<\/strong>, and Milwaukee<\/strong> could be in the crosshairs for multiple heavy rainfall events<\/strong>.<\/p>\n <\/p>\n \ud83d\udd25 Weekend: Turning hot and humid<\/strong><\/p>\n As the front eventually lifts northeast, warmer air surges northward<\/strong> by the weekend. Expect hot and sticky conditions<\/strong> across southern Wisconsin<\/strong>, with daytime highs<\/strong> soaring into the upper 80s\u00b0F (31\u201332\u00b0C)<\/strong> or higher in some spots. Dew points<\/strong> are projected to climb to 70\u00b0F (21\u00b0C)<\/strong> or more, pushing the heat index<\/strong> into the 90s\u00b0F (32\u201335\u00b0C)<\/strong> range.<\/p>\n This summer-like setup<\/strong> will dominate the weekend, raising the potential for heat-related stress<\/strong> and additional storm development<\/strong>, especially during the late afternoon and evening hours<\/strong>.<\/p>\n Stay alert for evolving severe weather updates<\/strong>, particularly Tuesday through Thursday, as southern Wisconsin<\/strong> braces for an active and potentially stormy pattern<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":" \ud83c\udf29\ufe0f Active start to the week in southern Wisconsin A moist, unstable air mass lingers across southern Wisconsin this Monday, fueling scattered showers and isolated thunderstorms, primarily west of Madison.
