So many things have to be there for snow to settle in ChCh. THK levels are very touch and go for sea level snow. The August 2011 snow event had a thk level of 512 over Canterbury. In my opinion, models need to be outputting a thk level of below 518, and a 850hpa temp of -8C or lower.Bradley wrote:Funny old system this one with 520 thickness levels over Christchurch for around 6 hours on Thursday morning, combined with 850hpa temps of -7C should have certainly produced a little sea level snow but there was nothing, it's like it has just forgotten how to snow in Christchurch the last 3 winters with no settling snow whatsoever even with all the ingredients seemingly there
The 500mb and 300mb charts typically will offer the best clues where heavy snow is most possible. The 500mb/300mb dynamics shifted north of Christchurch quite quickly early Thursday.Bradley wrote:Funny old system this one with 520 thickness levels over for around 6 hours on Thursday morning, combined with 850hpa temps of -7C should have certainly produced a little sea level snow but there was nothing, it's like it has just forgotten how to snow in Christchurch the last 3 winters with no settling snow whatsoever even with all the ingredients seemingly there
