Weather Summary for May 7, 2016

Compared to Friday, today was much cooler in northeast Minnesota and northwest Wisconsin with daytime highs in the 60s which is still a little bit above average for early May but yes a lot cooler compared to the record breaking heat on Friday.  Smoke was a huge issue in most of the Northland last night and this morning but a lot of this smoke moved away this afternoon.  Sky conditions ranged from mostly sunny to mostly cloudy with even a few showers passing through extreme northeast Minnesota at times.

A quiet weather pattern continues through Sunday with high pressure in control.  Expect low temperatures to be in the 30s and 40s tonight and Sunday night with highs on Sunday in the 60s to around 70 degrees.  An east wind is forecast to develop on Sunday near Lake Superior which will result in temperatures in the 40s and 50s.

Looking ahead...Multiple rain chances beginning Monday or Tuesday and lingering through Friday.  A slow moving low pressure system will approach from the west and southwest bringing a few rounds of rain to northeast Minnesota and northwest Wisconsin.  The better chances for rain appear to be on Tuesday and Wednesday the way it looks now.  Enough cold air could move in late in the week (Friday the 13th) to produce a few snow flurries in parts of northern Minnesota.
