This weekend continues to look mild, but I think record warmth is unlikely on Sunday (February 2nd) given a few things which I will get into a little further down in this post.
First for Saturday, should have widespread 30 to 35 degree high temperatures in northeast Minnesota and northwest Wisconsin. I can’t guarantee will see a whole lot of sun though.

Source region for this weekend’s warmth is currently over the Northern Rockies and will spread farther south/east through Sunday morning.

Sunday does look windy as will have very strong winds aloft (~5,000 feet) of 45 to 65 knots covering the Northern Plains and upper Midwest, some of this will mix down to the surface resulting in 20 to 40 mph wind gusts across the Northland.

Monthly outlooks much like seasonal outlooks are always a crap shoot, but here is the forecast for February 2020 per CFS model. Note: Don’t bet the house on this forecast being right.

Still dealing with widespread low clouds in the Northland today, but just like in previous days, we have seen a few brief breaks in the low clouds which has allowed for a tiny bit of sunshine, but overall it continues to be quite gloomy around here with the lack of sun.

High temperature forecast for Saturday, February 1, 2020.

…Weather Summary…
Mostly cloudy skies will continue tonight with areas of fog, haze and freezing mist. Lows will be on the mild side for this time of the year ranging from the teens to the upper 20s with winds out of the southwest at 5 to 15 mph.
Given how persistent the clouds have been for about a week, I don’t have much confidence will see much clearing on Saturday, but maybe will get a little more sun compared to what we’ve seen lately, will just have to wait and see. Highs on Saturday will be in the 30s with southwest or west winds at 10 to 20 mph.
This leads us to Sunday which still looks mild, but probably not as warm as what I was hoping for 24-hours ago. One of the issues I’m seeing is the warmest air moves over the Northland early in the day when 850mb temperatures peak in the +2 to +6C range, then will start to get into some cold air advection before Noon Sunday thanks to a fast moving cold front which is forecast to move through the area Sunday morning, so instead of seeing highs in the 42 to around 50 degree range on Sunday, it’s looking more likely will have highs somewhere in the 37 to 45 degree range which will still feel nice, but just a little cooler than what I was forecasting on Thursday. The deep snow pack we have right now doesn’t help either if you want real warm temperatures.
