2" snow on the ground at MSP International Airport.
January 19, 1982: Just over 17 inches of snow fell in the Twin Cities. Amazingly, it was to be outdone two days later.
January 19, 1917: 16 inches of snow falls in the Twin Cities.
Atmospheric Speed Bump
After a freak case of severe clear air turbulence over the Pacific 20 years ago my wife developed a formidable fear of flying. She'd grip the arm rest, close her eyes and grit her teeth. "Think of this as potholes in the sky" I whispered, trying to be helpful. I know, what a dork. "You don't scream when you hit a pothole do you?"
Pilots are smart enough to detour around thunderstorms and avoid icing when possible. Want to live a long life? Don't push the weather.
Variations in jet stream winds can create pockets of extreme turbulence, capable of severe injuries for people unlucky enough to be out of their seats or unbuckled. Airlines and universities are teaming up on promising technologies to pinpoint areas where conditions are most ripe for turbulence.
A scrawny Alberta Clipper may paint a few driveways white today and tonight; the pattern still not ripe for significant snow. If you're keeping score MSP is running a 10-inch snowfall deficit, to date.
The Great Lakes and New England bear the brunt of arctic air the next 2 weeks. Mild Pacific air penetrates inland, keeping our temperatures from falling off a cliff.
Old Man Winter pulling his punch? No, this won't be a rerun of 2014.

Minor Clipping. The next swirl of low pressure racing southeast pushes a couple inches of snow across the Dakotas into central and southern Minnesota, brushing MSP with a coating to as much as an inch of slushy accumulation. With temperatures close to freezing many roads and freeways will be wet. 60-hour accumulated snowfall: NOAA NAM and Aeris Weather.
Snowfall Potential. A few towns near the Minnesota River may wind up with an inch or two of snow over the next 18 hours; closer to a coating to half an inch for the Twin Cities. Dribs and drabs. Remember when it really snowed? Source: Twin Cities National Weather Service.
- During 2014, the average temperature across global land and ocean surfaces was 1.24°F (0.69°C) above the 20th century average. This was the highest among all 135 years in the 1880–2014 record, surpassing the previous records of 2005 and 2010 by 0.07°F (0.04°C).
- Record warmth was spread around the world, including Far East Russia into western Alaska, the western United States, parts of interior South America, most of Europe stretching into northern Africa, parts of eastern and western coastal Australia, much of the northeastern Pacific around the Gulf of Alaska, the central to western equatorial Pacific, large swaths of northwestern and southeastern Atlantic, most of the Norwegian Sea, and parts of the central to southern Indian Ocean.
