A look at surface temperatures from late Saturday afternoon. Note: We won’t be seeing any 60s or 70s quite yet in the Northland, still a little too early for that, but we should have widespread 40s in our area on Sunday.

Computer models are showing a rather stout ridge moving over the Plains for next weekend (~March 6 to 8) This could lead to widespread 40s and 50s for daytime highs in northeast Minnesota and northwest Wisconsin next weekend, while 60s are possible in portions of western/southern Minnesota. 70s and possibly even some 80s in the Central Plains for next weekend the way it looks now.

I’m still not seeing a consistent enough signal in model guidance which would indicate a more active weather pattern setting up across the Northland through mid-March, instead it continues to look pretty quiet with mostly minor precipitation events affecting our area over the next 2 weeks.

Split flow looks to continue into mid-March with an active southern branch, while the northern branch (polar jet) remains over Canada. Note: Need to see some phasing of the jets, or the southern jet to lift farther north before we have a chance to get a more significant storm to affect the Northland, and if anything its looking like we’d have a better chance at getting rain instead of snow should a larger storm take aim at our area toward mid-March.

High temperature forecast for Sunday, March 01, 2020.

…Weather Summary…

A few low pressure systems will be passing through the upper Midwest the next few days, but they won’t be bringing any precipitation to our area.

An occluded front/trough moves through the Northland Sunday morning, followed by a cold front Sunday afternoon/evening. Snow and mixed precipitation tied to this system will remain over Ontario on Sunday, although its possible that we may see a few snow, sleet or rain showers in extreme northern Minnesota later Sunday as that area will be clipped by a strong vort max which moves east out of Saskatchewan and across Ontario on Sunday – See water vapor loop below.
