Milwaukee is getting a rude reminder that it is still spring and not quite summer on Thursday, April 30, 2026, with shallow fog, a chilly start in the upper 30s, and some low-lying spots flirting with pockets of frost before sunrise. Showers are expected to build through the afternoon with a high near 46°F, so the commute and any yardwork plans are likely to feel damp and dreary. If you have tender plants out early, keep them covered or bring them inside until temperatures bump up later in the day.
Morning Frost And Fog
The National Weather Service expects frost to be most widespread north of I-94 and west of I-41, with Frost Advisories in place through 8 a.m. in several nearby counties. Gardeners will want to bring in or cover cold-sensitive plants overnight, since shaded lawns and typical low spots can hang on to frost and shallow fog during the early drive. This guidance comes from NWS Milwaukee.
Afternoon Showers
Rain showers are likely this afternoon, with a high near 46°F and about a 60% chance of precipitation. Most spots are expected to pick up under a tenth of an inch. Forecasters say to plan for hit-and-miss showers instead of a soaking all-day rain, though outdoor plans could still get interrupted by brief downpours, according to FOX6 Milwaukee.
Evening Commute And Overnight
Showers may hang around into the evening before gradually sliding out overnight, with lows dropping to around 35°F and light west winds. A few inland, heavier showers could mix in some small graupel pellets, but forecasters are not expecting hazardous travel or significant impacts. The National Weather Service also notes that additional frost is possible Thursday and Friday nights away from Lake Michigan, so it is not a bad idea to keep protecting sensitive plants and outdoor decorations, according to NWS Milwaukee.
Looking Ahead
Temperatures are set to rebound over the weekend, with highs in the low to mid 50s on Saturday, climbing into the low 60s on Sunday and the mid 60s by Monday. More showers and a few isolated thunderstorms could pop up Sunday night through the middle of next week, but forecasters currently expect any activity to stay below severe levels, according to FOX6 Milwaukee.
