December 3, 1886: Minneapolis hits a record setting 15 degrees below zero
Are weather extremes becoming more extreme over time, or is all this talk of increased volatility nothing but "alarmist hype"? Minnesota just went from the warmest year on record in 2012 to the worst winter in 30 years. From nagging drought in 2013 to the wettest June, statewide, in 2014.
We've always had our ups and downs but the weather roller coaster ride seems to be wilder than ever.
Steeper and deeper, with more twists and turns than a Stephen King novel.
It's probably not your imagination.
There's growing evidence that jet stream steering winds are becoming amplified over time; more erratic and meandering than average, resulting in some jaw-dropping cases of weather whiplash.
For example: November was the 9th coldest on record. Now weather models show temperatures topping 50 by mid-December. Warm enough for rain days before the Winter Solstice? It looks like it.
A shift in the pattern, possibly a symptom of El Nino warming of the Pacific, pushes a parade of storms into California, turning our winds aloft to the southwest next week. That could mean 40F by late next week, maybe a few days above 50 in mid-December.
No big storms are brewing but a cold twist aloft sparks a wet snow Sunday/Monday. That may be our last best hope for a white Christmas this year.
