North Island

Some cloud and the odd shower in the west with northwesterly winds, rain develops this morning in the southwest (Taranaki through to Wellington), chance of a heavy fall then rain moves into the upper North Island this afternoon.

The east coast is drier with high cloud, there may be a few spits of rain spreading from the west afternoon on wards. Later this afternoon southerlies move into Wellington bringing rain, rain spreads north in the west and up the east coast from this evening with the chance of an isolated heavy fall, maybe even some thunder.
