…Weather Summary…

Frigid weather the next few days with lake effect snow showers along the South Shore of Lake Superior and downwind of the larger lakes in northern Minnesota.

Arctic high pressure averaging 1046mb was over central Alberta this afternoon. Northerly winds and widespread cold temperatures were found east of this high today. 850mb temperatures at 1 PM Sunday ranged from -24C in central Manitoba to -18C in northern Minnesota. Temperatures across the Nortland this Sunday afternoon were only in the middle teens to middle 20s with wind chills ranging from around zero to 15 degrees.

Partly to mostly cloudy skies will be found in the Northland through Tuesday with occasional lake effect snow showers along the South Shore of Lake Superior in northern Wisconsin and also downwind of some of the larger inland lakes across north-central Minnesota including Lake of the Woods, Lake Vermilion, Rainy Lake, Leech Lake and Lake Winnibigoshish, and also off Mille Lacs Lake, although most of that snow should fall south of Aitkin County. 850mb temperatures of around -20 to -25C moving over the milder lake waters will create favorable conditions for lake effect snow with N-NW winds in place.

Outside of the lake effect snow, it looks mainly dry but a few flurries or light snow showers may occur from time to time tonight into Monday.

Lows tonight and Monday night will range from the single digits below to lower teens above zero, but it’s possible that some of the typical cold spots could get as cold as 10 below zero!

Highs on Monday will only be in the teens with record or near record cold high temperatures possible in the Northland for November 11th – See list below.

-International Falls: 9F set in 1995

-Hibbing: 15F set in 1986

-Duluth: 16F set in 1920

-Brainerd: 18F set in 1950, tied in 1986

-Ashland: 20F set in 1950

Little improvement from the very cold temperatures are expected Tuesday with highs in the middle teens to around 20 degrees.

Note: Milder weather is possible beginning next weekend (November 16th) which could last a while with temps at least getting back to where they should be for this time of year, meaning highs in the 30s instead of the teens.
