A very large low pressure system covers NZ with mild weather in the north and colder conditions in the south.

Some places in the south will actually warm up a little today while those further north stay warm, but colder air is coming in the days ahead for many places. Nothing major in the north but a reset back to normal.  Windier weather is moving in for some places over the next few days too, as low pressure deepens south of NZ.

Snow flurries will affect inland parts of the South Island today and colder air flows remain stuck around the lower South island until mid week. While a colder air flow is surging north this week the good news is that the most polar of it will be too our east. Still, wind chills remain a bit tough for newborn livestock for the next few more days in some areas.

Isolated thunderstorms, squalls and hall are also moving in off the Tasman Sea ahead of the strong W to SW flow moving in,

Here are some updated rain and snow maps for the next 48 hours.
