    Been fairly heavy all day. Hopefully Rangerider can give us an update later on how it was on the mountain. I had to work today so can only watch on in envy...

    With windhold happening it might not have been as good, should be good when it clears though.

    CT scans are normal - while Mrs LTB may not be bumping, it appears we should be good to go as long as we have some pain killers in tow [​IMG]

    Keep the white room stuff coming for another fortnight please.

    GN - if you are free from Fr 26/3 - Wed 31/3 and would like to show jnr LTB and I some of the good stuff in exchange for lunch and a beer (assuming it's not sheet ice) shoot me a PM

    It was always going to happen eh GN?
    I just like the redevelopment of the high over Siberia.
    It seems in a better more sure place than it has been recently.

    LTB, I had a niggly back before I went this year (Niseko) and on day 3 when bending over to get ski boots out of locker (being careful of a crook knee), it strained again. Major pain, but I took a Mobic, two panadol osteo, reminded myself that it was nothing compared to childbirth, and went skiing. Snow was too good! After a few days and an onsen every afternoon, I felt fine.

    Ah, the snow of Niseko is kind to us geriatrics!

    Around 30-40cm has fallen in the last 24hrs and it's still snowing. According to the avi report drifts of up 1.5m have developed in lee slopes over the last 36hrs. Avi danger still very high so they probably won't open peak gates today but maybe tomorrow if the wind abates. Going to pretty epic out there today.

    First thing this morning in the village

    ^ Worlds apart. I won’t show you a picture of my carpark.

    The rest of March is ok though, slowly accumulating fresh snow which should remain cold and dry above 2000m, though winds will be a problem. Currently we are frozen rock hard.

    Scattered flakes falling now.

    And you get plenty.

    Our recovery from ice is shaping up well, faster than forecast.

    Good things happening here: 10cm down this evening without a stitch of wind. We don't see vertical fluttering flakes often enough. Good for the soul. Sitting outside on the porch enjoying the show.

    16cm total at 800m and so little wind up there (yet). 7% water content. A good day today.

    And a bad one tomorrow with +8C at the top lifts and 60kph winds forecast.

    It is a day for some fun and casual and loooong side country powder lines with friends - you don't get enough of them in a season.

    Next week will be great for higher altitude touring. Looks a bit warm for the slack country (which doesn’t start all that high and ends really low.

    I’m quite excited about next week.

    Almost hot today, lets see how high it gets. +15? Such a shame as yesterday am top of Happo was -9C or so, today it is +6C.

    Yesterday had manky sludge below 1400m with poor skiing, great powder between 1700 and 2300m. Over 30-40cm deep and very little wind with temps below freezing above 1800m all day.

    Next week still looks great, but as for this time of year, the higher altitudes will be favoured.

    +20.7C in Echoland! 9.5 on top of Happo. No one likes this on their holiday's, but will, it is amazing to see what the weather can do in such a short period.

    Yes, tonight we get a tropical storm of sorts (seriously! 15C in the evening, 2cm of rain and 60kph winds at least)... and then snow to the valley floor tomorrow.

    1400hrs and 22.5C in Echoland. That has to be the high for the day!

    Hey Damian. What site do you get the Echoland temps from? I've got 15 degrees on mine. Big difference.

    The Japanese Meteorological Agency weather monitoring station in Hakuba
    http://www.jma.go.jp/en/amedas_h/today-48141.html?groupCode=33&areaCode=000

    My own weather station at 800m, higher than Echoland, reached 20 degrees, confirmed with a second calibrated digital thermometer.

    I worked outside all day on my snow melting project and no doubt it was hotter than 15.

    The top of Happo reached +9.5C

    Screen shot from the quite trustworthy JMA

    The whole thing is just bizzare.....

    It only got to 19.5 degrees in Yokohama today, compared to Hakuba.

    That would have to be some serious melting happening there [​IMG]

    Bizarre indeed. Seems common across our part of Nagano prefecture: +22 to 24C in Nagano City, Matsumoto, Omachi and some other randomly selected Wx stations near us or south. Yet Nozawa a little north of here only hit +12C.

    Well, possibly, but I don't think so.

    I've looked at the temperatures across Japan today, and there have been high temperatures pretty much west of Nagano. e.g. Kanazawa got to 24.9 degrees today, and 25.7 in Toyama!!!!!

    If there was a foehn wind, I would have expected Toyama to have been cooler than Hakuba.

    I think the very warm temperatures have pushed in from the west, and pushed over the top of the peaks behind Hakuba. Tomari, a mere 30km NW of Hakuba recorded 25.9 degrees!!!!!!!!!!

    Apart form slightly further north along the coast, the warm temperatures didn't penetrate further east than Nagano.

    Is there an actual reading for Echoland or are you assuming the temps are the same throughout Hakuba Valley. Just wondering why you are using Echoland as a reference as I didn't know there was a station here. I would be interested to know if there was one close by as I only have my own one sitting outside the office here. It would be good to compare especially with an official one.

    I use Echoland because it is the most readily identifiable low-land area of Hakuba. The phrase “..in Hakuba†might mean anywhere from the train station to slope-side in Wadano to the top of Happo. For foreigners, Echoland is easily identifiable at the same time almost the lowest altitude area in Hakuba. Specifying the low altitude was important given the temperatures were so high. I wouldn’t want people thinking it was +22Cin the ski areas, which would be very wrong.

    The JMA instruments are about 35m lower than Echoland in elevation. Mine are 100m higher and recorded a high of +20C. I’d say your thermometer is broken if you only recorded +15C

    Have a look at Sandy’s post and the JMA data from yesterday before it disappears: clearly Hakuba was not an error as other towns within 50km also recorded highs well over +20C. It was very warm, and remained mild at +13C most of the night until the thunder and lightning and very windy rain storm hit at about 2am.

    Here's some JMA data for around the warmest part of the day. I've marked Hakuba, Nagano city, Nozawa & Tokyo. I believe that the warm air pushed in from the NW, and hit the mountains. Only SOME of it spilled over and as far as Nagano, but not beyond (as indicated by the arrow):

    Thanks for the map, it is informative. Hakuba is cursed!

    This morning’s strong southerly has weakened and swung to the north at my house and it is now snowing reasonably hard. Hakuba is blessed!

    I am starting to think it may have been a foen wind as the highest temps in Nagano prefecture are all lee side of the highest mountain range. Yet by comparison Nozawa was much cooler, and it has no significant true mountains between it and the NW stream.

    Do you know where the weather station is? By the altitude on the site I would think it would be down towards the station. Although it looks to be only about 60 meters difference in altitude, there is quite a big difference between Echoland and the Station which is clearly evident by the amount of snow on the ground in each area. I find there are many micro climates here which again is evident from one end of the valley to the other.
    I won't argue yesterdays temps as I don't pretend to have a good thermometer and I am not that interested. At the moment my thermometer is saying 1 degree and it is dumping outside my window. The reading on JMA for 9am is 6 degrees so maybe a 5 degree variance for the 2 areas is possible.
    More importantly is that it is snowing and it looks like we have a bumper week ahead.

    No, almost impossible.

    It is +1C at my house as well, at 10.30am, the temps have fallen since 9am - look at the JMA site reading for 10am, it reads only 0.8C warmer than your thermometer at 10.20am. You can't compare 10.30am to 9am on a day like today when a forecast drop in temperatures arrived between 9am and 10.30am

    I don’t know exactly where the JMA instruments are –some where down town past Echoland. Most likely at the Yakuba.

    Lack of snow at the station relative to Echoland is only due in small part to any very slight temperature difference, not really even altitude difference of some 57m. The biggest driver is the precip shadow. Take a look at the east hills – they are much higher than Echoland yet get much less snow than Echoland and at times even Wadanao (I know because during heavy storms I ski on the east side hills as well). The reason is that they are further to the east of the main range and therefore deeper in the precip shadow, not because they are warmer (they are colder). Same applies to the station, which gets less snow than Echoland because it is further east.

    And yes, it’s great that it is snowing now – it was always going to snow today as forecast. Weather is weather no matter the type. Having said that, happy snow today does not invalidate the remarkable high temps of yesterday unles you attache emotional bias. And great weather next week is not more important than bad weather yesterday, that is spin. Data is data, fact are facts.

    We had snow flakes here while I was eating breakfast at 8:10 and the JMA site is saying 6 degrees so I don't know whats up with that. Not sure why you say yesterday was bad. Our guests loved skiing around in their tshirts with their young kids. Horses for courses.
    Call me selfish however I have to disagree with you that next weeks powder is going to be more important for me than what ever the conditions were yesterday. [​IMG]

    It was -6.3C at 2080m at 8.30am, and it was snowing up there. It was +4C at my house (800m) at the same time, and there were very random flakes in the gusting wind. The snow is create in cold temps and can easily fall, though much less heavily, into lower climate zones with above freezing temps. It happens all the time.

    I used the term ‘bad’ because most people, the vast majority, don’t fly here for skiing in +10C temps, even though very steep fast corn is about as fun as it gets for me, and I get it here until June. I thought yesterday was great weather as I managed to clear and melt heaps of snow for important non-skiing related purposes. I also thought it was great when the wind picked up and shut down the ridiculous and noisy Tsugaike “heli-skiing†gig. I also used the term 'bad' because you deferred attention from it to next week's snow falls, inferring that you thought it was bad.

    Next week’s powder will possibly be relatively thin and probably quite heavy in the low altitude resort terrain. As you say, horses for courses [​IMG]

    Blizzard like conditions at the moment here in Niseko. Blowing a gale and snowing with gusts up to 50 knots I reckon. Larry Adler lost the awning from their roof this morning. Weather should moderate a little bit this evening into tomorrow. With a bit of luck it could be another powder day tomorrow. Thursday was EPIC. Bottomless turns through the gates all day.

    33cm here at 800m, probably 50cm at 2000m, blue bird, strong wind last night loading up some areas on the previous ice, public holiday, perfect photography weather, race for fresh tracks, quickly warming temps below treeline... very gong show with a frenzy of rats on cocaine with the stage set for a mishap. Heading down valley to some empty road-side perfect trees.
