The weather maps appear ready to deliver the warmest air mass Minnesota has seen in four months. Medium-range upper air maps continue to favor very mild air as March arrives.

Let’s start with next week first.

40s again next week

Our current February chill gives way to milder breezes this weekend. March arrives Sunday with another mild Pacific air mass.

Persistent Pacific flow

We may see a few cooler days in the first two weeks of March. But the overall upper air pattern forecast maps have been remarkably consistent. They suggest a well-established mild Pacific flow for most of the first two weeks of March.

NOAA’s 16-day GFS temperature output cranks out highs in the 50s for the Twin Cities around March 11. That’s still a long way off for total forecast confidence, but the mild signal has been persistent for a few days now.

The last time the temperature hit 50 degrees in the Twin Cities was on October 26 when we topped out at 56 degrees. So if we get to 50 in March it will be the warmest air mass in over four months.

Of course, Minnesota can still expect more freezing weather and snow in March. But it’s been interesting to watch the signals for an earlier spring accumulate over the past few weeks.

Stay tuned.
