The drastic change from colder than normal conditions to warm dry conditions is complete and will continue into the weekend. With the warm temperatures, cool water and light winds, we will see lake breezes develop each day this weekend.
These lake breezes that see afternoon onshore winds near large bodies of water are the result of unequal heating of the land than the water. Another feature of these breezes can be the development of late afternoon isolated showers inland, away from the water. We often see this phenomenon occur over the UP of Michigan and east of the Sault, inland of the North Channel in late spring and early summer.
A few clouds move in Friday, but that won't stop temperatures from hitting 20°C in the afternoon. A few isolated showers are possible along the St. Marys River later in the afternoon due to lake breezes over northern Michigan.
Saturday will start with sunny skies in the morning, and then a few clouds move in during the peak heating of the afternoon as daytime highs reach 21°C again. Isolated showers are possible in the late afternoon for inland locations away from Lakes Superior and Huron and quickly dissipate as temperatures cool in the early evening.
Cloud cover Sunday morning will give way to sunshine in the afternoon as the temperature climbs to 19°C. The warm and lack of widespread rainfall will continue well into next week.
