Detroit Weather Alert: Patchy Frost Early Thursday Before Sunny Warm-Up Into the 60s
DETROIT, MICHIGAN — Southeast Michigan is in for a cold, crisp night as skies clear and temperatures dip near the freezing mark outside the metro area. The National Weather Service in Detroit/Pontiac has issued a frost advisory for early Thursday morning, warning that patchy frost could develop before sunshine brings back seasonable warmth later in the day.
Patchy Frost Expected Overnight
Brief light rain moved through the region early Wednesday but is expected to clear by afternoon. Overnight, temperatures will fall into the mid-30s for rural areas and upper 30s around Detroit, Ann Arbor, and Port Huron, cold enough for frost to form on vehicles and outdoor plants.
Residents are urged to protect sensitive vegetation and garden plants before nightfall, as frost could damage tender foliage.
Sunshine Returns Thursday
After a chilly start, Thursday will deliver picture-perfect fall weather, featuring mostly sunny skies and highs in the lower 60s. Light northwest breezes will add a touch of autumn coolness but keep conditions pleasant for outdoor plans.
Friday Brings Clouds and Possible Showers
By Friday, clouds will increase across southern Michigan as a weak weather system approaches. A few isolated showers are possible in the Tri-Cities and northern Thumb region, though most areas are expected to stay dry.
Mild Weekend Ahead
The weekend forecast looks dry and slightly warmer, with temperatures reaching the mid-60s by Saturday and calm conditions continuing through Sunday.
The National Weather Service advises residents to stay weather-aware overnight and cover outdoor plants to prevent frost damage. After that, southeast Michigan can look forward to several days of calm, comfortable fall weather.
