"Each one should test his own actions. Then he can take pride in himself, without comparing himself to somebody else." — Galatians 6:4.

Mark Twain once said "Comparison is the death of joy." Human nature is a stubborn thing. We can't help comparing ourselves to our peers and neighbors. Who's ahead, who's behind; the grass is usually greener elsewhere.

We compare today's weather with what came yesterday, or a 30-year average. This winter was tame compared to an extended polar vortex two years ago.

Meteorologists compare model solutions, looking for trends and agreement. Finding the signal amidst the noise is an ongoing challenge. What to believe, when?

The Arctic is running 7-14F warmer than average and I'm convinced there's a domino effect. The models are erratic. Sunday's front is now a no-show; we may see 40s Friday into Sunday before a bit of colder air late next week. A nuisance snow is possible late Sunday; any big storms detour south of Minnesota until further notice. Yes, it's been half a winter.
