Milwaukee woke up to a crisp start Wednesday, with temperatures hovering near 37°F and mostly clear skies early in the morning, plus a Frost Advisory in place until 8 AM CDT on May 6. Gardeners are being urged to cover tender plants, while inland commuters away from Lake Michigan are dealing with frosty grass, icy windshields and a brisk start to the day.
Frost Advisory Details
The National Weather Service issued the Frost Advisory at 4:46 AM CDT, warning that temperatures could dip to around 31°F, cold enough to damage sensitive outdoor vegetation, according to NWS Milwaukee. The advisory is mainly aimed at inland and sheltered pockets of the metro, with lakeshore neighborhoods expected to stay a few degrees milder. Officials are urging residents to "take steps now to protect tender plants" before the morning sun melts away the frost.
Today And The Week Ahead
Skies turn partly sunny today, with a high near 55°F and a light west breeze at 5 to 10 mph. Tonight looks partly cloudy with a low around 38°F, and another round of frost is possible Wednesday night. A chance of light rain showers moves in Thursday, mainly after 10 AM, with highs in the mid-50s, and spotty showers may linger into Friday as temperatures climb into the low 60s. Saturday is poised to be the warmest day in the stretch, with highs near 72°F, west winds of 5 to 15 mph and gusts up to 30 mph, along with a slight chance of afternoon showers or an isolated rumble of thunder; for more on the broader setup, see our earlier May 2 breakdown.
Practical Tips
Cover potted and tender plants tonight and again Wednesday night, and hold off on planting warm-season seedlings if you can. For the morning drive, budget extra time to scrape frost from your windshield and dress in layers. Afternoons will be noticeably milder, so if you are eyeing outdoor projects, aim for Saturday when the warmup really starts to show.
