Map – 16 day rain outlook: West is wet, East is not

As we’ve been saying this week the first half of September looks warmer than average – and the spring westerly flow is kicking in.

This favours wet weather in the west and dry weather in the east. The 16 day outlook, courtesy of the US Govt/taxpayer (as the NZ Govt and two tax funded weather agencies currently both charge high rates for this data) shows exactly this set up. 

Heaviest rain is set for the West Coast – with driest weather mostly focused around North Canterbury to southern Marlborough.

Things might change a bit from the maps below as spring’s chaotic pattern moves in – but this is what the largest of the super computers are picking for the first half of September as of today:
