We head into the final week of April with cooler than normal temperatures in the forecast for the foreseeable future.
Normal high temperatures for the last week of the month are in the mid/upper-50's with overnight lows typically averaging out in the mid-30's. While not extreme, forecasted temperatures for the next week will remain below normal the entire stretch with upper-40's/low-50's. Looking at the upper air pattern, Northern Michigan and the Western Great Lakes region for that matter will continue to see intrusions of colder air dropping down out of Canada keeping any warmer temperatures suppressed south/west of the area into next week.
In the short term, rain and yes, even some snow will roll in mainly Friday across Northern Michigan. Low pressure centered along the South Dakota/Nebraska line Thursday morning will track right across Northern Michigan Friday. While rain will fall to our west Thursday, that's where it should stay through Thursday night. We can't rule out a few light showers/sprinkles in the counties near Lake Michigan, but bigger rains hold off until Friday.
Rain will fall Friday and as temperatures fall Friday on gusty west winds as low pressure moves east, snow will mix in and eventually dominate by Friday evening. This is no large storm by any means but we are forecasting some accumulating snow Friday afternoon/evening with the axis of this falling across the Straits region. Places like Cheboygan/Beaver Island/Harbor Springs could see 2-3" of snow by Friday night.
This will all come to a quick end though and the upcoming weekend looks dry with some sunshine, although highs again will remain stuck in the 40's. Rain sweeps back in early next week.
