Monday’s News: Southwesterlies ease, Warming up Tuesday on wards, Mainly settled after today

Here’s what is making the weather headlines today….


Well the weekend’s southwest front ended up being about what was expected, bit of annoyance really but nothing much to it.

Today this airflow is easing with showers for much of the South Island clearing this morning (coastal Southland may continue to see the odd shower for the rest of today), showers for some North Island regions may not clear till evening. We have an exception in the South Island being Tasman where there may be a few heavy showers that may not clear till later this afternoon or evening thanks to a trough and some cold upper air.

It’s been a frosty start for some inland areas this morning and we can expect frosts again overnight, the frost risk starts to subside Wednesday morning and further again on Thursday but a risk is still there for inland areas. No point crowing about day time temperatures today as they are a bit cool.


While temperatures are a bit cool today from tomorrow they start to warm up, on Wednesday highs in the east may be in the mid to late teens.


The week ahead is mainly settled and dry apart from clearing showers today, we do have some rain for the upper North Island on Wednesday, clearing Thursday. A front moves into the far south on Friday bringing heavy rain into South Westland, rain or showers for Southland and perhaps Otago.

There should be a fair amount of sun, expect some cloud for western regions from Wednesday.

Sunday may see some heavy rain move into parts of the upper North Island thanks to a tightly packed deep low, something to keep an eye on.

The “Precipitation percentage of normal” map below shows this weeks weather in one snap shot basically, you can see the rain for the upper North Island and rain for South Westland, the rest of New Zealand is mainly dry.

The map below runs through to Monday 4th September. Blue coloring means that part of the country is likely to see more rainfall than would normally be expected at this time of year, red means less rainfall is expected and white is an average amount of rainfall. The more intense either red or blue then either scenario is more true.
