Developing cold change looking pretty weak

The expected change to cooler weather following this second spell of warm July weather is still on track – but it looks significantly weaker than first thought.

A low in the Tasman is currently visible on our satellite maps – but it is weakening as it moves towards New Zealand.  It will bring rain, showers and drizzle patches to various regions as it falls apart over the country around Tuesday and Wednesday,

By Wednesday – as expected – the winds are likely to start to dip more west to south west, then by Thursday a general south west flow will spread over the country, dropping temperatures.

However this south west change is fairly weak – in fact, incredibly weak for northern regions.

Highs in Auckland and other northern regions will be around 16 to 18 degrees over the next day or two – but by the end of the week we’re back to 14 or 15.

At the other end of the scale we have Southland and Otago hovering into the low to mid teens in recent days, but by Thursday the highs drop back to single digits, around 8 or 9.

Frosts, if any this week, will unlikely be too heavy and snow is expected to be limited to the mountains.

We may be in the depths of winter, but July is so far proving to be a very mild month, despite the brief cold snap last week.

Time is running out for winter to really kick in – generally speaking things start to warm up by mid-August as sunlight hours become noticeably longer and the rest of July looks fairly average to above average temperature-wise.
