Dry pattern! Cold through Thursday; warmer weather this weekend; colder risks return mid/late next week

A few days ago, a meteorologist at the National Weather Service in Duluth used the word “humdrum” in one of their forecast discussions to describe our weather pattern as of late, and well I would have to agree with that after looking over the long range computer models, as a dry/fairly quiet weather pattern looks to continue around here looking out the next 2 weeks.

For the most part, this winter has been a quiet one. Sure there’s been quite a few minor and the occasional moderate snow event sprinkled in since December, but for the most part this winter has been on the boring side of things, yes we had that powerful post-Thanksgiving weekend blizzard, but not much after that when it comes to a major winter storm hitting the Northland, however this winter is still running above normal in snowfall across the Northland which is a little interesting.

Long range computer models have changed considerably for next week, yes I realize models change daily, but this is one of the bigger changes I’ve seen in a while.

Threat for a storm impacting the Northland next week has pretty much disappeared in the GFS and Euro models today as the storm track remains well south of our area.

Shown below is the 50 member European ensemble (EPS) snowfall forecast for Duluth through March 4th. Check out the spread in snowfall totals for Duluth as we get into late next week, this shows the spread in the EPS model and its members, as some members still show quite a bit of snow in Duluth late next week, others show nothing.

The late week warm-up is still on track as a nice ridge builds SE into the upper Midwest, but there are signs showing up in long range model guidance for a flip to colder conditions once again by mid to late next week.
