A southwesterly airflow lies over New Zealand today.
The odd shower for the western North Island this morning then clearing, Northland (more so in the west) doesn’t see the odd shower till midday then clearing there in the evening. Risk of a light shower about Wellington, showers more likely in the evening. Showers move into Wairarapa late afternoon or evening.
The odd shower possible for the West Coast otherwise mainly dry, the odd light drizzle patch possible by late afternoon or evening for Marlborough (especially in the east). Canterbury has the odd drizzle patch or shower, showers a little more persistent from evening Banks Peninsula southwards.
The odd shower about Southland and perhaps Otago at times, mostly cloudy and dry otherwise. Showers more likely from evening.
