Is this NZ’s shortest cold snap of 2019? Just 12 little hours…

NZ has had some short lived cold snaps this winter but the one coming in today and tonight is truly the shortest. While both Friday and Saturday will see a large portion of the country warmer than average a nationwide southerly change tonight will reverse that trend making for a colder than average night in many places.

But…by noon Saturday it’s ending and the warmer than average afternoon kicks in as the colder southerly change quicky gets pushed east of NZ by a stronger westerly flow.

It’s yet another sign we’re entering a spring pattern where cold snaps becoming shorter lived and westerly winds dominate.

Next week the westerlies dominate mostly from the W to SW direction which means some in the south may have colder air at times while those further north have a mild week ahead, especially those in the north east. Places like the Bay of Islands look fairly dry next week with highs in the late teens, possibly even 20 degrees. Dunedin on the other hand may have some days with single digit highs.
