December 20, 1989: Minnesotans are hard pressed to find snow cover across most of the state. Only good places to cross country ski are at Grand Marais and along the Gunflint Trail.
Spoiler Alert: Freakish Warmth into New Year's Eve
Quick, what's the number for 911? Old Man Winter is being held hostage, bound and gagged somewhere in northern Canada. The polar vortex has been frozen in place this "winter".
I can't believe I'm tracking the rain-snow line, still high above Minnesota, in late December. The maps look more like late March.
Why, Paul? El Nino, the Arctic Oscillation, hot air rising above the U.S. Capitol? It's probably a combination of factors, all conspiring to keep our weather tracking in from Seattle, not the Yukon, at least through the New Year.
Many are just fine with Perpetual March, if not a wee bit unnerved.
December is running 14-18F warmer than average, statewide. For perspective: International Falls has yet to see a subzero low. The record for latest 0F low at KINL is December 20, 2001.
The average high now is 26F, but metro area highs approach 40F Tuesday & Wednesday. Christmas Eve looks dry, but a storm may push rain into the metro Christmas Day with snow central and northern Minnesota; maybe a plowable accumulation up north. If you're traveling next Friday you'll want to stay up on the latest.
We stay mild for 2 weeks; GFS guidance hinting at more of a polar front after January 2-3 or so; maybe a real cold front, something potentially polar. In the meantime the sheer persistence of this warm signal is amazing.
Old Man Winter has been kidnapped.

Record-Setting December Continues. It has been a head-scratching month, more March than December. Here's an excerpt from this week's installment of Minnesota WeatherTalk, courtesy of Dr. Mark Seeley: "The December climate pattern across Minnesota is tracking much like November did, warm and wetter, only even more amplified. Average temperature for the month is ranging from 14 to 18 degrees F warmer than normal, and many new warm minimum temperature records have been set such as the low of 38F at MSP and 40F at Rochester on December 13th. On December 14 the temperature never dropped lower than 44F at Caledonia. A high degree of cloudiness has accompanied this warm temperature pattern, fueled by a great deal of water vapor in the air. MSP also set a new high dew point record on December 13th with a reading of 38F. Daily cloud cover has average over 80 percent for the month so far, so little sunshine has made it through..."
December Temperature Anomalies To Date. Over the entire "conus" of North America temperatures are running about 5F warmer than average, but as much as 20F warmer than normal over central Canada. Minnesota is about 14-17F warmer than average as of December 18. Map: WeatherBell.
Which Season is Warming Fastest? The warming signal is showing up most vividly and consistently during the winter months. Here's a clip from Climate Central: "...Even though these are the same areas that tend to have above average temperatures during El Niño winters, this pattern is also consistent with the long-term trend we are seeing with global warming. Winter is the fastest warming season for the majority of the U.S. The exceptions: the Northwest, where fall is warming the fastest; the Southwest where springs are experiencing their greatest rise in temperatures; and Texas, which is pushing it’s sweltering summer heat to a new level..."
What Just Happened in Solar Is a Bigger Deal than Oil Exports. So says Bloomberg Business; here's a clip: "The clean-energy boom is about to be transformed. In a surprise move, U.S. lawmakers agreed to extend tax credits for solar and wind for another five years. This will give an unprecedented boost to the industry and change the course of deployment in the U.S. The extension will add an extra 20 gigawatts of solar power—more than every panel ever installed in the U.S. prior to 2015, according to Bloomberg New Energy Finance (BNEF). The U.S. was already one of the world's biggest clean-energy investors. This deal is like adding another America of solar power into the mix..." (File photo: Solar City).

What's more, this unintentional geoengineering may have already impacted global warming, Wild said. Global temperatures held fairly constant from the 1950s to the 1980s, and warming only accelerated starting in 1985, when the global brightening seems to have begun, Wild reported in a study published this month in the journal WIREs Climate Change. He also sees evidence that this unintentional geoengineering affected the world's hemispheres differently. Temperatures held steady until the mid-1980s in the Northern Hemisphere, where most of the world's population lives, and spiked up sharply afterward..."
