Declining Great Lakes Ice Coverage
According to Climate Central, the amount of peak ice cover on Lake Superior has been dwindling over the last several years. Note that the current ice cover of Lake Superior on February 9th was around 8%, which is well below the long-term average of nearly 35% for this time of the year.


Declining Lake Superior Ice Coverage
Not only is the ice coverage on Lake Superior dwindling, but it is dwindling across the entire Great Lakes. The peak back in the mid 1970s was around 80%, while the average in 2020 was a little more than 40%. According to NOAA's GLERL, the Great Lakes was around 19% ice covered as of February 8th.

Cold Air Continues
The coldest air of the season continues over the next several days with high temperatures running well below average. Here's the 850mb temp anomaly from midday Friday to midday Sunday, which shows the core of the cold air sliding southeast through the Midwest through the weekend. Note that highs may not even get above 0F across parts of the state with wind chill values dipping well into the subzero range. Note is some of the coldest air that we've had to deal with in nearly 2 years. Prior to Sunday's subzero high of -3F, the last time we had high temps colder than 0F in the Twin Cities was January of 2019.

Extended Temperature Outlook
Here's the extended weather outlook for Minneapolis through the weekend ahead. Note that temperatures will stay VERY chilly with readings running nearly -20F to -30F below average. This will be the longest and coldest stretch of winter. It does appear that there will be some improvement as into the 2nd half of the month. There will be a light snow chance on Thursday and perhaps again on Saturday. Both chances will be light, but because temperatures will be so cold, roads will become icy across the region.


Wednesday Weather Outlook
Here's the weather outlook for Minneapolis on Wednesday. It'll be another cold day with highs only warming into the single digits through the afternoon. Westerly winds at 5-10mph will keep wind chill values in the subzero range all day.

Wednesday Meteograms for Minneapolis

Wednesday Weather Outlook
Here's the weather outlook across the region forWednesday, which shows temperatures running well below average. In fact, many locations will be nearly -20F to -25F below normal with some folks across northern MN staying below zero.


Extended Temperature Outlook
Here's the ECMWF & GFS extended temperature outlook for Minneapolis through the 3rd week of February. Note that temperature readings will still be running well below average through much of that time. The GFS is a little more aggressive with the cold (which I don't believe), while the ECMWF is more believable. Regardless, both models suggest the worst of the deep freeze will be over at some point during the 3rd week of the month. Stay tuned...
