A cold front moved through our area last night and brought a much cooler and less humid air mass to Northeast Michigan. However, some afternoon instability led to pop-up showers/thunderstorms south of Alpena. Any leftover showers will diminish this evening with partial clearing.
High temperatures so far this month in Alpena are averaging slightly below normal. However, the first half of the month was significantly colder than normal and the last half of the month has been running a few degrees above normal. From May 1-15, the average of the high temperatures in the first half of the month was 8 degrees below normal. Looking at May 16-29, high temperatures in that period averaged 5 degrees above normal, thanks to the recent stretch of warm temperatures from last weekend until Thursday.
The coolest temperatures in the forecast will come Saturday and Saturday night. Winds out of the northwest will supply cold air this weekend originating from central Canada. After that, temperatures will go on a warming trend through the middle of next week. Winds will shift out of the southwest on Monday, pushing warmer temperatures into our area. Highs will be near 60 degrees Saturday, then Sunday’s highs will be in the middle to upper 60s. Temperatures will likely get a little above 70 degrees Monday afternoon.
Overnight lows will cool to around 45 degrees. Saturday morning, temperatures will be around 50 degrees. Partly cloudy skies are expected throughout Saturday with highs near 60 degrees. Temperatures will drop to the middle 30s early Sunday. The second half of the weekend will be mostly clear with highs around 66 degrees. Cloud cover will increase Monday afternoon/evening and highs will reach the lower 70s.
