Milwaukee, Wisconsin – Thunderstorms could disrupt holiday plans across southeast Wisconsin as early as Wednesday afternoon, bringing lightning and localized downpours just days before July 4th celebrations.
According to the National Weather Service in Milwaukee, a 20% chance of storms begins after 1 p.m. Wednesday, with continued chances Thursday and Friday nights. The best chance for widespread showers is Thursday night into early Friday. High temperatures will remain in the mid-to-upper 80s through Friday, with a surge into the low 90s by Saturday.
Residents along I-94 and near the lakefront should plan for slick roads and potential weather delays Thursday evening into early Friday morning. Local events and fireworks setups may be impacted by intermittent rainfall and lightning. Officials recommend checking forecasts frequently and securing outdoor equipment in advance.
Wednesday brings the first sign of instability with a high of 85°F and light winds. Thursday is hotter at 83°F, with thunderstorm chances increasing after midnight. South winds up to 10 mph will push humidity levels higher into Friday and Saturday. Independence Day (Friday) itself may start dry, but a 20% chance of storms lingers into the evening.
By Saturday, heat becomes the main concern, with highs reaching 91°F. Storm chances return Saturday night (50%) and persist into Sunday. Keep devices charged, stay hydrated, and monitor NWS alerts as shifting patterns could affect timing.
