70 F. high at St. James, Minnesota yesterday.
39 F. high at Staples, evidence of the sharp temperature gradient and subsequent wind shear that whipped up as many as 3 small tornadoes near Saint Leo.
58 F. high in the Twin Cities Monday.
49 F. average high at KMSP on March 31.
42 F. high on March 31, 2013.
Land Of Mega-Extremes. While temperatures flirted with 70 across southwestern Minnesota, and tornadoes touched down not far from Canby, residents of Duluth and International Falls were enjoying 30s with 24″ of snow still on the ground in both cities. Good grief.
I’d like to lock Mother Nature in my basement and throw away the key. March came in like a polar bear and went out like a (rabid) mountain lion, with blizzard conditions over the Red River Valley yesterday, but that wasn’t the most unusual feature of yesterday’s weather map.
In 40 years of tracking the weather I have NEVER seen a tornado warning and a blizzard warning in effect (simultaneously) for the same county. That happened yesterday in Yellow Medicine county; tornadoes moving at 40 mph causing structural damage near Saint Leo – the county under a blizzard warning for high winds and snow expected to move in Monday night. A new level of weather-whiplash. A new level of bizarre.
Whispers of the Polar Vortex return today as cold exhaust shakes the trees outside your window – a coating of slush possible in the metro; a few inches of snow for Brainerd. But we all realize that spring in Minnesota is always two steps forward, one step back.
A clumsy atmospheric waltz.
No more 60s in sight anytime soon, in fact heavy jackets linger into late week with a few days in the 30s and low 40s. It’s premature to toss around inches, but there may be enough cold air in place for a slushy snow event by Friday. But even if it does snow a high sun angle guarantees rapid melting, with 40s returning next week, even a shot at 50F.
If anyone asks the average high reaches 65F in the Twin Cities by the end of April. Extended models show a cool bias. We won’t be boating anytime soon.
Longer term an El Nino is brewing; warmer Pacific water which often correlates with milder winters here. That’s more of a prayer than a forecast by the way. But we go from one extreme to the next.
Maybe we’ll catch a break.

Minor Structural Damage. Abraham Grant snapped this photo near Saint Leo, showing EF-0 damage to outbuildings – no reports of injuries from yesterday’s freakish tornadoes in Yellow Medicine County.

Taking Weather Whiplash to a New Extreme. Tornado warnings issued for a county under a Blizzard Warning? True, blizzard conditions weren’t expected until Monday night, and convection whipped up in the “dry slot”, a surge of warm, dry air that pushed into southwest Minnesota, resulting in highs in the 70s, a sharp temperature gradient and subsequent low-level wind shear that spun up a couple of small tornadoes. (Map: Earth Networks).
“Hey Paul, I have a question. Have you ever seen a confirmed tornado (Warning) in the same place where a Blizzard Warning is also in effect? Hard to believe my eyes right now. Then again in Wisconsin yesterday there was elevated fire danger in the same areas where rivers were flooding. What could possibly be ahead??? Cue the locust.”
Short answer? No.
Who’s Your Mamma? Sorry – I’ve been standing too close to the Doppler. No locust showing up (yet), but Mike Gaddow in Prior Lake captured a great shot of cumulonimbus mammatus clouds as thunderrshowers pushed across the metro Monday evening, “pouches” of rain and hail illuminated by the setting sun.
Spring Is In No Great Hurry. This probably won’t come as much of a surprise, but there’s every indication we’ll limp into spring this year. The southern USA is warming up nicely, but a series of cold intrusions sweeping out of Canada will result in a sharp north-south temperature gradient capable of whipping up a series of storms: rain and snow. The best chance of precipitation comes Thursday into Friday, possibly a rain/snow mix ending as a few inches of slushy snow Friday. Graphic: Weatherspark.
Too Early To Panic (Much). Again, I tend to go with “persistence”, which is a fancy way of saying go with the flow, don’t deviate from the current pattern and trends. Spring is taking it’s sweet time, with only a few tantalizing glimpses of real warmth. I’m not buying a major snowfall for Friday (yet) – I want to see a few more computer models and see if the solutions are consistent. But there’s certainly a potential for a “few inches” of slushy snow Thursday night into late Friday. GFS data shows the best chance of a hearty pile of snow south/east of the Twin Cities. Too early to say with confidence, but we’ll keep an eye on it. Feeling lucky?
A Reason To Keep On Going. After showing the GFS model solution it would be cruel and unusual not to leave you with a few ragged scraps of hope. Here it is, courtesy of NOAA’s CFS (Climate Forecast System) model, showing highs consistently in the 60s or milder after about April 23. My confidence level is low in anything that far out, but let’s pretend this might actually happen. Graphic: Ham Weather.
A 1,720 Foot High Tsunami? I thought it was a typo at first, but apparently not. Good grief. I’m feeling better about being near the center of the North American continent. Here’s an excerpt from an eye-opening account at Quartz: “…Calamity struck at 10pm on July 9, 1958, when a 8.0-Richter-scale earthquake rammed the Alaskan coast up and northward. That impact shook free between 40 million and 60 million cubic yards (30.6 million and 46 million cubic meters) of rock and ice that rimmed the Lituya basin, dumping it 3,000 feet into the bay below. The 1,720-foot monster that reared up as a result shot through the bay at 100 miles per hour (161 kilometers per hour), as Susan Casey details in her book, The Wave: In Pursuit of the Rogues, Freaks and Giants of the Ocean…”
Higher Probability Of El Nino By Summer of 2014. The threshold is .5C, and we should reach that in the Pacific as early as May or June. For a little light reading and more than you ever wanted to know about a brewing El Nino and ENSO in general, check out this 29 page PDF from NOAA NCEP.
Update On California Drought. Residents of the western USA may be praying for a moderate to severe El Nino warming phase of Pacific Ocean water, which correlates with more frequent storms for California and a more active southern branch of the jet stream. Here’s a good summary of the deepening drought from Peter Gleick at scienceblogs.com.
4.8 Magnitude Quake Hits Yellowstone. The tremor was reported on Sunday in an area riddled with earthquake faults – more details from earthsky.org. (Map: Google).
Parallel Parking In The Arctic Circle. If you missed Thomas Friedman’s latest Op-Ed in The New York Times it’s definitely worth a read – with a son in the Navy I found this especially fascinating. Here’s an excerpt: “…More important, you learn how crucial acoustics are when operating deep under ice with no vision and no GPS satellite to guide you. Or, as the New Mexico’s captain, Todd Moore, 40, put it: It’s like every day “engaging in a knife fight in a dark room: the only thing you can do is go after what you hear.” You can’t see the adversary. You can’t see the ice keels, but you can hear enemy subs, surface ships, whales, calving icebergs, schools of fish and bounce sound waves off them with sonar to measure distances…”

People Can Predict The IQ Of Men, But Not Women, By Looking At Their Face. Deep down you always knew this, right? Here’s an excerpt from psypost.org: “New research published in PLoS One has found that a man’s facial characteristics contain some clues about his intelligence. Surprisingly, the same can’t be said for women’s facial traits. And the particular male facial characteristics linked with intelligence are a mystery…”
How You Know If You’re A Serious Techno-Geek. At least this new wearable camcorder doesn’t look too dorky. Details from Gizmag: “Panasonic has unveiled the world’s first 4K 30/25p wearable camcorder, the HX-A500. Following in the dua-body footsteps of the HX-A100, the camera part of the new 4K-toting device can be worn on the head sans helmet thanks to head mount, while the main body – which now includes an LCD monitor for checking shots on the go – sits in an armband worn by the user…”

13 of 14 Warmest Years On Record Occurred In 21st Century – U.N. Here’s a clip from a summary at The Guardian: “13 of the 14 warmest years on record occurred this century, according to the UN. Publishing its annual climate report, the UN’s World Meteorological Organisation said that last year continued a long-term warming trend, with the hottest year ever in Australia and floods, droughts and extreme weather elsewhere around the world. Michel Jarraud, the WMO’s secretary-general, also said there had been no ‘pause’ in global warming, as has been alleged by climate change sceptics. “There is no standstill in global warming,” Jarraud said…”

Food And Water Shortages May Prove Major Risks of Climate Change. Scientific American has more on the implications of continued warming; here’s a clip: “…In that light, climate change becomes a risk management proposition, particularly given the uncertainty about exactly how bad impacts might become and when. The worst risks include sea level rise for small islands and coasts, flooding, the breakdown of infrastructure in the face of extreme weather, loss livelihoods forfarmers and fishers, food insecurity and heat-wave deaths. Expect a big demand for energy for air conditioning as the 21st century continues. Some of these impacts are already here, from a meltdown of polar ice and glaciers everywhere to higher rates of sea level rise than the IPCC predicted in the past…” (Image credit: NASA).
Climate Change Impact On Agriculture To Accelerate. Here’s an excerpt of a longer look at the latest IPCC report and implications for agriculture, worldwide, courtesy of The Guardian: “…On average, we are looking at yield decreases. By the 2030s most of the changes in crop yields are negative,” says Andy Challinor, University of Leeds climate researcher, author on the paper, and on the new IPCC report, too. “The second half of the century is when the negative impact in yields becomes more common.” The researchers found this by comparing results from almost 100 independent studies—more than double the number used in the IPCC’s fourth assessment—that measured the impact of higher temperatures on three of the globe’s primary staple crops: maize, wheat, and rice…”
