A period of unsettled weather has set in bringing rain and showers to the west, and is likely to hang around and spoil the weekend.

MetService lead meteorologist Mark Todd said a weak front was moving over the country from the Tasman Sea, leaving an unsettled westerly flow in its wake.

"So this means showers to most western areas in both islands, while it will be mostly dry in the east."

This westerly flow was likely to hang around until Sunday.

🌵 2 towns, both in the east, are tracking for a record dry July.

🌵 10 towns, mainly east, are tracking for a near-record dry July (i.e. 2nd to 4th driest on record).

Today would start fine in most places, before showers kicked in this afternoon, with some heavy about Auckland.

Snow lowered to 900m in parts of the South Island overnight, with road snow warnings in place for Lindis Pass (SH8), Crown Range Rd and Milford Rd (SH94).

Another weakening front embedded in this westerly flow was expected to pass over the South Island on Saturday, then the North Island on Sunday.

Heavy rain was forecast for Fiordland and southern Westland from Friday to Saturday, with a low risk of severe westerly gales about exposed parts of coastal Southland including Stewart Island, and Clutha.

The westerlies would ease later on Sunday, as a narrow ridge of high pressure moved on to the country, followed by another front on Monday.

This front was expected to bring rain to western parts of the South Island and Northland later on Monday.
