Milwaukee is preparing for a weekend of wet weather as the National Weather Service forecasts rain and thunderstorms. A weather system moving in from the west is expected to bring significant rainfall, with some areas potentially receiving up to 2 inches. Thunderstorms are likely to occur intermittently, accompanied by the possibility of strong winds and lightning. This weather pattern is part of a broader system affecting the Midwest, driven by a low-pressure system intensifying as it moves eastward.
