higher parts of the strezlecki's ice??
Meh...... Sunday looks colder.
strange how they forecast snow to 6-700mt the last system but yet imo this one
looking at that,id say sunday night/mon morning def coldest time
Anyone care to clarify how this things shaping up for NSW Saturday-Wednesday?
This is kinda what I'm guessing from the info you guys have been giving out....
Saturday - lotsa snow, uber windy, epic if the lifts aren't all on wind hold
Sunday - more snow (but not as much as Sat), windy, cold temps keeping snow in great nick
Monday - less snow, but touring should be epic as it's still cold, but not as windy
Tuesday. - no new snow at resort, good touring in the morning before it turns to snot below treeline in the arvo?
Wednesday-Friday - snow might be ok up high in south-east aspects, but freeze/thaw on anything with sun or under treeline.
What are your thoughts on my thoughts? (please say snow will be in good nick all week!)
Sunday 3:23pm and 33.67secs.
Looks good. imo.
Day temps Sunday and Monday will be similar but Sunday will feel colder with the wind chill.
Always better to come down sooner
Prediction/question from an obsessed beginner in the forecasting world.
Ive been trying to get my head around EC and GFS and it looks like some of the moisture will arrive late friday night/saturday morning.
In saying that GFS seems to have a weird loop going on with the 850 temp over the mountains though seems to have relatively cold uppers. This being the case what are peoples thoughts on avoiding r!@n late friday/early saturday.
Awesome chucked a sickie and blew the whole schedule up. Any word on Mt P and Eyre - you must be itching to start lapping the bowl. Sorry CC for being off topic.
I think everyone agrees moisture arrival Fri. Cold pool is lagging on the 850 temps. I'd buy a $2 plastic poncho, if Skiing Friday. imo. Though at the higher resorts, might be ok. Sat should be snow only. imo. Hope that helps.
Thanks for that astro. No skiing Friday just the weekly pilgrimage up to hotham. just trying to decide on where to ride on Saturday morning. I guess we'll wait and see.
That's if anyone will be riding due to wind hold. I've got my fingers and toes crossed. Bom forecasts of damaging winds to be equal to or even greater than earlier in the week has me worried.
Well Perth has had a lot of wind but bugger all rain out of this one so far. I've a sneaking suspicion it might not deliver as much snow as some think. I hope I'm wrong.
It only clipped Perth. Bulk of the moisture is well south. Plus perth doesn't have a 2200m mountain range running north south to suck every last drop out of it.
We're working on it. Think Mt WASTED. Might take a while, but I'm sure we'll get there. That is my prediction.
Stay on topic.
I dunno about visibility on Monday, for touring. But it would be super dry.
Yeah I think it is a fair summary freeheel. The forecast has lingering cloud through to Tuesday, sometimes the best systems for BC and inparticular the easy-to-access high zones like LBC are the ones that quickly clear out so you have that instant good follow-up visibility. Not sure the snow will be all that dry by the time Wednesday comes around.
Mount Tassie if anything. I don't see a 528 line anywhere near Vic for this one, which doesn't spell low level snow to me. I'm actually surprised they're even forecasting to 800 metres. At this point in the season I'd much rather a hell of a lot of snow to 1000 metres than a drier system which brings the odd shower to 500 metres.
Is it still looking good for snow on the western side of the blue mountains/CT? THinking about getting the kids in the mood on sunday with a drive up to blackheath...
I think so.
Based on previous experience i'd be thnking Monday will be one of those days that is fairly fine early in the morning. Then as the sun gets up a little cloud starts forming over the mountains and there will be some lighter snow showers with sun poking through occasionally.
Still looks windy on Monday. Wind + Mountains usually = cloud across the highest parts of the range.
IMO - monday good for sidecountry. Tuesday better for getting further away.
But that window on Monday morning, would be something to talk about in the highest country.
The north east part of the Range might be okay for vis.
Monday morning still looks a bit brutal for the Range on second thoughts. 40 to 60 knts on the peaks above 2150m. Ouch.
The wind chill at 2200m must be around -40. The snow will get better through Monday ( thaw (dry) out). Tuesday Morning looks epic and it will preserve till Wednesday, as Ii think the wind chill will be still -20 with temps around -2 Tuesday night at the warmest.
what elevation is that temperature map for??
Its at 700hpa
altitude varies vs air pressure
rough rule of thumb...post snow change 2100 metres.
Interesting to see a significant change in the forecast for Melbourne on Sunday, now predicting rain and maximum of 11C, which seems to be in alignment with the predictions in this thread. Hopefully, we will get a set of decent follow-up snowfalls over the next two-three weeks, as all too often lately an early-season dump has become an isolated event.
There was talk yesterday of maybe seeing some snow in or south of Canberra, but I can't see that happening with the current setup on any of the models?
Hey do you think if the pressure drops than we get a reduction in elevation from say 3000 m to 2100m AHD. It feels like it sometimes, but I have never been higher than 2500 m RL in alpine environement
700hpa height is relative to temp
PV + nRT
hpa is a measurement of Pressure, which is proportional to temperature in the ideal gas law ( Pressure * Volume = n (mass) *R(constant) *Temperature.
So I assume that 700 hpa is pressure at roughly 3000 m AHD, but would be lower if the pressure was lower, during a storm event.
Sea Level Pressure is av. 1013 hpa.
Than for every 1000 elevation we have a loss of 100 hpa
What time are we expecting the colder air to move through the resorts? Looking a tad warm currently
Looking at any one thickness in isolation is fraught IMO, interpreting 700 hpa and 850 hpa together gives a better sense of the Dynamic/ vibe
New BOM 4 Day is out, looking good. Maybe a little shorter than snowmaggedon 1.0? So I'm thinking totals more like 60-70cm for NSW
were did you see max of 11 for melbourne sunday slog?
AXS R going for 50-60mm precip 24 hr to 10am sunday. Then 20-30mm till 10am monday. Thats NSW.
Are there any signs of a follow up system in the next fortnight. We all seem to be foaming over this one so much that I haven't heard if there is anything on the horizon? Too soon?
SPG - just be happy with 150cm base by July!!!!
You kids are getting greedy
AXSR showing some of the tightest iso bars i've ever seen. I wouldn't be suprised if everywhere is on wind hold tomorrow and for most of Sunday.
I just googled melbourne weather and that was the first thing to pop up
Severe Weather Warning for damaging winds
for people in the North Central, North East, South West, Central, West and South Gippsland and East Gippsland forecast districts
Issued at 4:00 pm EST on Friday 27 June 2014.
A strong cold front is crossing the Bight, with an associated low pressure system crossing waters south of the Bight to be just west of Tasmania by Saturday morning. Strong to gusty northerly winds will reach gale force at times tonight and Saturday ahead of the cold front, then colder and squally west to southwest winds will extend eastwards across the State in the wake of the front as it crosses Victoria on Saturday.
Damaging winds of around 60 km/h with peak gusts of about 100 km/h are forecast for parts of the North Central, North East, South West, Central, West and South Gippsland and East Gippsland forecast districts on Friday night and Saturday, particularly over elevated areas. Alpine Areas are likely to experience winds of 60 to 80 km/h with peak gusts around 120 k/h.
A wind gust of 104 km/h was recorded at Mt Hotham this morning.
A wind gust of 100 km/h was recorded at Kilmore this afternoon.
First thing to pop up when I google the current weather is a damned good boner. I'm way over excited at what's happening.
