CAUTION THIS IS NOT A WEATHER UPDATE BUT A MEMORY OF THAT AMAZING STORM IN AUG 2011. Enjoy the read. SEVERE WEATHER UPDATE: THE BIG CHILL - SNOW WILL FALL IN WELLINGTON REGION TO 100 METRES ASL 13 August 2011 at 11:21 Severe Weather Update: Ok places to expect snow to fall an settle from Sunday afternoon onwards. Rimutaka Hill will very likely be CLOSED for 2 to 3 days as this storm is far worse than the previous one in July, the road may open briefly during a couple of fine breaks during this event. Temarua, Birchville, Akatarawa Valley, Brown Owl Maoribank, Kingsley Heights, Riverstone Terraces, Whitemans Valley , Blue Mountains, Higher parts of Silverstream, Haywoods , Higher parts of Stokes Valley. Kelburn, Maungaraki , Wainuiomata, Khandalah, Karori, Brooklyn, Higher parts of Tawa an Porirua. Any land areas upbove 100 metres above sea level will see the snow settle. Snow could be as deep as 20cms maybe more above 200metres with lighter falls down to 100 metres. Be aware snow falling below 100 metres will melt quite quickly so get those cameras charged. The Hutt Valley will see snow that many of you may not have seen before this low the last snow that fell this low in Upper Hutt was 1983 where people made snowman at Brown Owl School. Weve had a few snowstorms since then of course but nothing as much as what this storm is expected to drop in the way of snow. Computer models are holding fast and true in the main as it continues to track a sizeable snow storm due to hit parts of New Zealand tomorrow (Sunday) There is potential for some record breaking snowfalls over the next few days in pockets of the country and it appears that waves of snow activity will sweep up southern and eastern parts of both Islands. The start of the coldest air still seems to be arriving tomorrow and perhaps a little earlier than we thought during the day. It seems to be coming in waves, with the first band moving through later tomorrow and overnight before a possible easing for a part of Monday in the south. Now for some people they might think theres not much snow but a heavier surge should arrive later on Monday and Monday night. Indications are for places such as Canterbury that snow could be around 20cm deep in Christchurch, possibly up to 30-40 cm during the whole event and heavier falls on the Port Hills and further inland. Exact figures on how much snow will fall and where it will take place as theres always a risk that these things dont come off. It has the potential to be quite significant so its always good to be prepared. The wintry weather in exposed areas of the storm is likely to last up to 3-4days but cold temperatures could linger for considerably longer. For some southerners theyve had enough of the snow this winter although it was only a brief cold snap almost 3 weeks ago however the one kicking in tomorrow starting in the south could have much more venom attached. This icy blast appears more prolonged than the previous one with substantial precipitation over a wider area and winds to boot. One or 2 locations in both islands may see snow fall for the first time in years if not decades.Its always difficult to pinpoint exactly where the snow will fall and how much theres going to be but one thing for sure is that the cold and the wind will make it feel very wintry for a few days. This still appears significant and blizzard like conditions will take place in some regions over eastern and southern districts of both islands. It looks as if the rain and snow will comes in waves but parts of Monday in the south and Monday night could see the heaviest falls during this storm cycle. The lower North island looks as if it will cop a pasting and the outbreak may hang in longer than their southern neighbours. This vigorous southerly will also make it feel much colder than the actual temperature readings so windchill is a concern for both people and livestock. Looking at the weekend weather ahead of the polar blast and it appears quite sunny in many areas with temperatures near average or above for much of the weekend. So there you go get ready and keep warm. Stockup on those warm foods as people living in higher suburbs may well be having Monday off!!! The southerly air flow that is about to form just south east of New Zealand is one of the most significant southerly outbreaks I have ever seen - and Im sure many other forecasters are saying the same thing. The air will be coming from directly off the Antarctic iceshelf where its -30 and colder. All the lows and highs are joining forces to suck air up from the South Pole as far north as the sub-tropics. The polar air will travel thousands of kilometres - the energy in this system is simply impressive. Keep you posted Daniel Talbot. That was probably one of my biggest weather updates. Id love to see this happen again. I love the snow and the scenery it produces. Was a great photo opportunity as well. Hope you all having a great day. :)
