My trip to Des Moines got canceled later so I'll get to have a few cold ones and watch it snow from home. Couldn't have had a better timing on this thing. Snow started right when sun was coming up and will go all day into tonight. Can't beat it6 points

For a winter lover and transplant from Minny- it's a great day in C.IA. See below- so serene and beautiful out, it's hard to describe - but those here understand the beauty of mother nature other than just the "draw backs".6 points

Shifting the 30yr running mean ahead by a year (1992-2021), and we see that August and January warmed by an additional 0.2°F. This is despite both months being colder than their 2020 predecessors. This makes sense since both months have been notorious for excessive torching over the last 10-15 years, this last year being no exception (as it stands 2022 is following the Jan transcript too, unfortunately.) Unsurprisingly, 2021 dropped Dec by 0.2°F. 2021 was 0.9°F cooler overall than 2020, yet still 0.5°F above the 30 year mean. The statistical oddities start showing up however during that magical, offputtingly excellent second month of the year. February, given the mid month cold snap and -2.7°F departure, actually cooled the running mean by an additional 0.2°F. This means that as it currently stands, the newest February 30 year running average is cooler than the one 31 years ago by 0.1°F. Amazingly, given the current -ENSO and improving guidance for an impending cooler than average February, this anomaly could drop further. To add to this insanity, if March ends up cooler than usual (likely given -ENSO), March could drop its 30 year running average down to the 1981-2010 mean or even colder. For the record, while the running average for March didn't budge, Mar 2021 was 0.8°F cooler than normal, so this is just an artifact of rounding.6 points

Frogs will start chorusing almost any day now. Absolutely love the biorhythms of life esp those driven by photoperiods but I'd pass it up for a good February. Chorusing and La Nina seem like a contradiction although they're not connected to anything but increased daylight. Maybe we can get the frogs to chorus in some serious cold and snow despite longer days.5 points

NZ is like 1.8k miles away, Australia 2k. Wonder if they'll be able to hear it.4 points

GeologyHub (awesome channel, just a volcano nerd dishing out no-BS science) made a video today regarding yesterday morning's eruption. Tomorrow he will have a new video out about this evening's eruption, which appears to be orders of magnitude larger.4 points

Earlier eruptions were primarily steam above 11k feet. Given the total darkness, it looks like were was more solid ejecta this go around.4 points

Man, this back edge has been over performing. It’s been basically stationary for a few hours now. No way to measure accurately anymore, but I’d guess 2.5-3”. Enough on the ground to form some 1’ drifts in my backyard at least. Winds are gusting to 40 mph and the temp is down to 18 degrees so it’s all blowing around now and is pretty near looking like a blizzard at times. At the very least I’m hoping this will be enough so my girls can go sledding tomorrow’s like they’ve been begging to do all winter. IMG_0148.MOV4 points

2008-09 had a fairly cool and troughy February with a couple of snow events. Otherwise might have to go back to 1992-93, although Western WA got screwed pretty hard in February 1993 north of Clark County.4 points

*sorry for the wall of text, i just love this stat stuff and i can go on and on abt it There is a mechanism that has driven the January average upward, and it's really a combination of several factors, mainly statistical. You must keep in mind that the graph reflects 30 year running averages, so it's just a composite of those 30 years. This means that the beginning of the time period, encompassing the late 1940s through 1970s, includes pretty much all of the great January tempests during the SeaTac POR, including January's '47, '49, '50, '54, '57, '63, '69, and '80. And those are just the "great" Januaries. Believe it or not, there was once a time when January regularly came in with a sub-40°F average, and the years in between were no exception. From 1946 to 1964; a sample size of 19 years; there were only four years where January averaged 40°F or more. In that same time span there were two years where January came in with a sub-30°F average. This means that during that stretch, you were only twice as likely to come across a 40°F January as you were a 20°F January! That would be unheard of during a 19 year stretch today. The next piece on the puzzle emerges when we look beyond January 1980. That month is a very important; not only is it the last "great" January, but it is also the last sub-35°F January KSEA has ever recorded. In fact, that month marks the end of the "great January" era, and from then on, most Jan's are 40°F+; it's as if that year was a sort of changing point in how January behaved in our climate. Putting it all together, this means that as we slide the 30 year average forward, starting in the 1949-78 package, we not only lose our best Januaries, but we also start factoring in our warmer, more modern Januaries. This essentially means that, as we slide forward year after year, we're replacing our coldest Januaries with our warmest ones. This has a profound effect on the graph, producing a warming trend which exceeds what you would normally expect from AGW. You might ask yourself then, wouldn't that insane warming trend in the 30 year Averages slow down after the 1980-2009 package, when the "great January" period leaves the 30yr focal point? Well, in short, it does. Since the late 2000's, the Jan warming trend has slowed down significantly on the graph, to a rate much closer to AGW. -- As for why it's been running warmer than February by a solid 2°F+, that answer lies in the latter. February's deal is pretty much the opposite of January. As it turns out, the 70's and 80's, with one massive fat exception, weren't all that kind to February. This last decade however has seen a few more sub-42°F's, and of course Feb 2019. For the last decade or two, we've stalled the graph by replacing the warmer Februaries with the cooler ones, allowing January to play catch-up. I do not think it is physically possible for January to beat out December, let alone lose much more ground. In the coming decades, February's luck will run out, and January's more moderate rise will prevail. December will start warming more regularly. That's just my guess though. Perhaps there are certain mechanisms in a warming climate that have promoted cooler weather patterns during February and warmer ones during January. I have no earthly idea.4 points

That climb in January average temperatures is astounding. I just don't see why January would warm so much while February (and December to a lesser extent) stay cool. If anything, due to the maritime climate, sun angles, and a touch of seasonal lag, January should stay our coldest month of the year. And even if La Niña's tend to have the flip switched later in the winter there's no reason we should be experiencing more of them in a warming climate. I wonder if it's truly down to luck or if there's something else at play that has become dominant for our Januaries.4 points

I think I’ll be recommending that we send employees to work from home today for the afternoon. Due to safety reasons. Not for my own personal desire to watch the snow…4 points

Rain has changed to snow in KC about 2 hours ahead of schedule. I would think this is a good thing.3 points
