The Grasshopper – The Latest Snow Forecast

Monday 23 September – Snow showers today, then mostly fine


Synoptic Outlook

A wee little low and its trough will give the Aussie Alps a nice top up today of about 3-7cm. The previous few days have chipped away at our snowpack, but this snowfall should freshen up the place nicely.

The rest of the forecast to Thursday will be mostly fine as a high sneaks out of the Great Big Bight and over the Aussie Alps.

Monday 23 September

Glorious snow showers! It’ll start petering out from afternoon after the NW winds have turned to the SW. About 3-7cm should accumulate.


Tuesday 24 September

Mostly fine, but SW winds will push some cloud over Vic resorts.


Wednesday 25 September

A fine start, then some afternoon cloud. Light winds.


Thursday 26 September

Plenty of sunshine with a bit of cloud about the place and a NW breeze.


Extended Outlook

Friday will see a front slip under us, then the weekend may hold a few showers as a shallow low passes by to the north.

High pressure should build next Monday with fair weather likely through until mid-week.

Monday 23 September – A messy wet front, then cold winds with freshies



Synoptic Outlook

A rather wet looking front will pass over the South Island today then the North Island on Tuesday, messing up the Kiwi snowpack a little.

Fortunately, cold air follows close behind, and after a little bit of snow on Tuesday, about 5-10cm should tidy up the place on Wednesday with the passage of another front.

Cold southwesterlies on Thursday will blow a gale across the country, with a little more snow falling over the Southern Lakes and on Ruapehu.

Monday 22 September

Scattered rain over South Island ski fields, clearing and becoming fine over the Southern Lakes this morning and Canterbury this afternoon, as gale to severe gale northwesterlies abate. Some snow may fall about the tops.

Stiff westerly winds push cloud onto lower slopes of Ruapehu this morning, then there’ll be some afternoon showers, falling as snow above 1800m.


Tuesday 23 September

A mostly fine morning for the South Island followed by some light afternoon snowfalls. Chilly westerly breezes.

Heavy rain on Ruapehu, turning to snow during the afternoon as gale NW winds change to a cold southwesterly.


Wednesday 24 September

Snow showers spread up the South Island during the morning as strong NW winds change to the W-SW. Accumulations should be around the 5cm mark.

Westerly winds will be going bonkers on Ruapehu, and occasional snow showers will become more frequent during the afternoon. About 10cm of powder should pile up.


Thursday 25 September

Strong to gale W-SW winds over the South Island push in a few snow flurries over the Southern Lakes, while skies should be mostly clear over Canterbury.

Snow showers continue on Ruapehu while SW winds also continue to blow a gale.


Extended Outlook

Strong to gale W-SW winds continue to blow over the country during Friday, while snow showers also continue to pepper Ruapehu.

A cold front will bring just a dusting to the South Island during Saturday, but rain to Ruapehu during Sunday.

Things look to remain unsettled early next week with the makings of one or two decent snowfalls on the cards.

Japan Forecast – Powder day for Honshu & Sunshine for Hokkaido before Mayhem Monday hits.


Thursday 7th March (Japan time)


Ten-day snow accumulations are tantalisingly sizeable. Source::


Now that we’re in the thick of spring, we’ll see it all this week. Rain on Honshu will turn to snow tonight, with Friday set to offer up some good powder and what could be the best conditions of the week for resorts there. Hokkaido will offer fantastic feel-good weather along with a predawn dusting on Sunday to top it all off. Things take a turn on Mayhem Monday however, as an angry low rampages over Japan with super strong winds, heavy rain and snowfalls eventually abating on Tuesday.


Ten-day snow accumulations are tantalisingly sizeable, but the bulk of this will pile up on mid-upper slopes with wetter slushier stuff lower down. Adding to that, some models show a rip-snorter of a snowstorm next weekend that may or may not come to fruition. It would certainly be a fairytale end to what is my last forecast for the season. That’s right folks, this is indeed my last and it has been a blast, but there are still plenty or turns to be made this season before hanging up the skis. See you all again when the southern hemisphere turn on.


Thursday 7 Mar:

A low sitting off the Pacific Coast of Honshu is currently dumping snow onto mid & upper slopes, but rain lower down. Temps will steadily drop from later this afternoon as strong northerly winds hit, with snowfalls lowering to base levels. It’s a lovely day on Hokkaido with plenty of sunshine and winds out of the N-NE.


Friday 8 Mar:

Snowfalls will gradually peter out on Honshu as northerly winds turn to the west. Accumulations from this event will mostly be within the 15-25cm range, so make the most of this fresh bonanza while you can. Hokkaido should have a beautiful sunrise and sunset, with cloud and maybe a snowflake or two in between.


Saturday 9 Mar:

A high passes over southern Honshu in the early hours, turning the winds over Japan to the SW and causing temps to steadily rise to a balmy day with a mix of sun and cloud.


Sunday 10 Mar:

There’ll be a predawn dusting on Hokkaido, with central parts receiving the most, eventually clearing to a beaut day as winds ease. On Honshu, high cloud will thicken during the afternoon as a low approaches from the East China Sea, spreading rain up to central Honshu at night.


Monday 11 Mar:

The low will rampage up Japan with strong winds and warm temps adding to the mayhem caused by rain. There’ll be really heavy falls, especially on the Pacific side of Japan, which will turn to snow about the tops of Honshu at night. Snow will fall to low levels on Hokkaido at first, then gradually lift to upper slopes at night.


Tuesday 12 Mar:

The angry low will track away to the north while rain and snowfalls gradually peter out, but there may be more showers later, which will fall as snow on upper slopes. Winds will blow a gale over northern Honshu and Hokkaido.


Wednesday 13 Mar:

Snow showers and flurries will blow in on a westerly wind, which will be quite strong. The snowfalls will be a bit wet and heavy at low levels.

North American Forecast – Spring Snowfalls Continue


Wednesday 6th March (Pacific time)


Yet another awesome ten-day snow accumulation chart. This one however, shows good snowfalls more evenly spread throughout North America. Source::


The second week of spring looks set to be a doozy with good snowfalls more evenly spread throughout North America compared to previous weeks. This is all thanks to a broad and complex low-pressure system, which drifts over western North America during the next few days, followed a cold airmass pushing south later in the week. With this being the last forecast of the season, there couldn’t be better way to sign out of one of the best seasons in living memory – this one will go down in the books for sure. Happy spring skiing to you all, I’m heading into the back country and will reappear once the leaves are falling in the Southern Hemisphere.


Thursday 7 Mar:

A broad and complex area of low pressure covers almost the entire western half of North America providing scattered light-moderate snowfalls for all-and-sundry, with pockets of heavier falls along the Rockies during the first half of the day as well as the Sierras during the second half. It may be a bit wet and heavy on lower slopes of many resorts due to fairly warm temps.


Friday 8 Mar:

Scattered snowfalls throughout western North America will gradually clear late in the day or at night as all of that low pressure migrates east. The mountains of Wyoming, Utah and Colorado look to gain the most with some heavier (moderate) falls, but again it might be a bit wet and slushy on lower slopes, as temps remain warm there. Temps should be cold enough elsewhere.


Saturday 9 Mar:

High pressure will see a mix of sun and cloud, with just a smattering of leftover flurries over the American Rockies during the morning and isolated snow showers in the Sierras.


Sunday 10 Mar:

Weak low pressure develops over the southern states to provide isolated snow showers for the southern Cascades and Sierras, which eventually spreads inland to Utah, Colorado, Arizona and New Mexico at night with decent, moderate-ish falls on the cards. Plenty of sunshine for resorts farther north.


Monday 11 Mar:

After what feels like an eternity, Canada will finally see a good dump of powder courtesy of a cold front rolling in from the Gulf of Alaska. There’ll be moderate-to-heavy snowfalls along the Coast Mountains and light-to-moderate falls further inland. The front will also roll over the Cascades later in the day with moderate-to-heavy falls.

Snowfalls farther south over Utah, Colorado, Arizona and New Mexico may actually be heavy at times, especially over the lower two states, with possible thunderstorms to boot.


Tuesday 12 Mar:

The front from the previous day continues to spread light-to-moderate snowfalls south and east from Canada and the Cascades all the way to the Sierras and Utah. Meanwhile, moderate-heavy snowfalls over Colorado, Arizona and New Mexico will ease and become few and far between.


Wednesday 13 Mar:

Scattered light snowfalls throughout the Rockies, but as the cold airmass continues pushing south, there’ll be some slightly heavier, moderate-ish falls over Arizona and New Mexico. Any leftover flurries along the Pacific crest will clear early.

Latest Outlooks

Who is The Grasshopper ?

The Grasshopper. Some say he hatched one summer on a Himalayan plateau. As cold Autumn winds set in, he stumbled upon a scrap of goretex shed by some unfortunate climber and turned it into the smallest snowsuit ever. Then he strapped himself into a nearby leaf and carved his way down the mountains, hitching a ride with some hikers back to civilisation.

Now Mountainwatch’s resident meteorology sensei, this season we can expect a lot from the little critter. His beloved monthly outlooks across Australia and New Zealand over the southern hemisphere winter are being replaced with outlooks for both Japan and North America over November and December leading into the northern hemisphere winter. From there, the little critter will go into overdrive producing weekly forecasts for Japan and North America from December through to March. No doubt he’ll be run off his feet, so it’s a good thing he has six.
