A few showers possible Friday and Saturday but overall a dry pattern into next week

  • A few showers are possible in parts of the Northland Friday and Saturday, but a lot of us will likely miss out on getting anything more than a brief light shower or sprinkle over the next few days.
  • Daytime highs Friday and Saturday are forecast to be in the 60s to lower 70s, but it could be cooler closer to Lake Superior if winds become easterly, and this is a possibility both days. Note: High of 70 in Duluth today (May 13th) first 70 or warmer temperature in Duluth since May 1st when the temperature hit 83. We’ve had 2 days so far this month with a high temperature of at least 70 in Duluth, normal in May is 6 days at or above 70.

A desert like air mass over the Northland today with relative humidity values of only 15 to 25% across the area, with some locations even below 15% this afternoon.

Note: Duluth, Minnesota had the same dew point temperature as Phoenix, Arizona at 4 PM CT today. Both locations had a dew point of just 25 degrees!

With how dry it is, the fire danger remains very high across much of Minnesota with extreme fire danger in parts of northern Minnesota (red area on map)

Very high fire danger also covered all of northwest Wisconsin today.

An upper level ridge was over the Great Lakes today while NW flow aloft covered the Northern Plains.

A few disturbances over the Northern Plains this afternoon will be moving east and over the upper Midwest Friday and Saturday bringing a chance for some rain showers to parts of the Northland, but it still doesn’t look like will be seeing any heavy rain or all days rains with this setup.
