Today's weather

Severe weather warnings remain in force with heavy rain and severe gales for many parts of the North Island. For the latest, check MetService warnings.

Niwa forecaster Chris Brandolino said there would be rain and possibly some hail for the upper North Island.

"We'll see the winds still brisk and strong. Cold for everyone, I mean we'll be lucky to hit the mid tens in Auckland today.

"People down south are probably thinking they'd love to see 14 or 15 as they won't escape the single digits down across the South Island."

He said there would be a break in the wind tomorrow then another system would approach from the west again.

"Winds not nearly as strong, but the winds will become gusty again, we'll see some showers ... I do see much warmer weather coming as Sunday rolls around and for the start of the school holidays."

Meanwhile, temperatures are forecast to plummet in the South Island tonight, making wet roads icy and bringing frost to the mainland for the first time this year.

Snow is coating mountain passes including Arthur's Pass where chains are required and towing vehicles are being turned back.

Snow and ice was an issue for inland Otago and the road to Milford Sound while in South Westland, strong winds were continuing to cause problems for high sided vehicles.

Christchurch is expected to dip to 1°C and Reefton is expected to dip to -1°C.

Metservice forecaster Tom Adams said motorists would need to watch for morning ice. Growers could also be affected.

"Agriculture, horticulture need to be aware it's going to be a cold night tonight and take relevant precautions. Tomorrow night looks a little bit warmer as a fast moving front crosses over and then getting cold again on Friday, potentially down to -2°C in Queenstown."
