This higher res radar pic at 12:15pm today shows that small cell right over Central Park in Henderson…RODALCO wrote:The rain radar may have been out of calibration today. It was bucketing down with rain in Central Park Drive, Lincoln, Henderson, while the radar only showed tiny light yellow dots.
+300 hours! Yikes that's a long way out..Bradley wrote:The more of these forecasts the better, next week has been looking unstable for a few runs of GFS now!
It was more a remark on how consistent GFS has been in forecasting a stormy and unstable week next week, obviously nothing specific that far out just a general trend I was remarking onSnwAddct wrote:+300 hours!

was north canterbury always like this though? even 5 years ago i only remember one stormy afternoon downpour in all the time i worked in the amuri basin but always dry, thought it was geographically stuck in a rain shadow from almost all directions.Richard wrote:Neat looking cloud spwill
Digging some of the garden in the weekend i noticed that its getting very dry again, starting to think will we ever see another flooding rain again, be coming up three years the last time we've had such an event.
Not for such long periods as this, this is not normal, sure March was wet this year but really all that did was give the sub soils a good wetting, a wet period where the country side was totally sodden was about three years ago. Even over the last 15 years, as a kid i remember the Ashley river north of Rangiora used to have a mostly open braided river bed, hasn't been a flood now for 15 years to clean out all the over grown vegetation.shovelopikis wrote:was north canterbury always like this though? even 5 years ago i only remember one stormy afternoon downpour in all the time i worked in the amuri basin but always dry, thought it was geographically stuck in a rain shadow from almost all directions.Richard wrote:

Interesting. I did a quick and dirty calculation from the Riverside station data (not far from Culverden), and it shows the following decadal averages:Richard wrote: Not for such long periods as this, this is not normal, sure March was wet this year but really all that did was give the sub soils a good wetting, a wet period where the country side was totally sodden was about three years ago.

It is getting drier, a farmer not far from me was telling me recently that going by his father weather recordings we get about 100mm less rainfall per year than back in the 50 & 60's.
Yeah it's interesting how memory can't be completely relied upon normally, stats don't lie 2010-2016 by average has been as wet or wetter then 5 of the last 9 decades...TonyT wrote:Interesting.

1920s 714mm
1930s 667mm
1940s 861mm (2 years missing)
1950s 755mm
1960s 668mm
1970s 771mm
1980s 692mm
1990s 696mm
2000s 640mm
2010s 695mm (to 2016)
So, the 2000s were the driest decade, although the 60s and the 30s were similar. The 40s were clearly the wettest decade, but the 50s and 70s were also wet. Interestingly we haven't seen a wet decade at this site since the 70s.
Not for a while yet but July and August could bring some interesting weather by the sounds of it,,,NZ Thunderstorm Soc wrote:A terrible day to end Autumn in Geraldine.
Dull, cold and overcast all day with no wind at all.
Hope the winter months will bring some decent weather here?
