Warm weather on the way to some parts of the country thanks to subtropical winds

Warm weather is on the way for some parts of the country thanks to subtropical winds, but some regions can expect rain too.

Temperatures Tuesday could reach 30 degrees Celsius in some places, according to WeatherWatch.

A warm northwest, which would be sup-tropical for those on the North Island, was expected to increase temperatures on Tuesday and possibly Monday as well, WeatherWatch said.

Daytime highs in the eastern North and South Island were strongly forecast to be in the mid to late 1920s.

WeatherWatch said the incoming warm subtropical winds would be caused by a high output from northern New Zealand.

That height was over northern New Zealand on Sunday, bringing sunny weather and high clouds.

The high pressure system would be located in the northeast of the country on Tuesday.

The anticyclonic flow around it would reach into Samoa and Fiji and push that airflow down and over New Zealand.

However, a colder southwesterly flow would drive it away all Wednesday and Thursday nights.

MetService said on social media that heavy rains were coming for the central regions.

The hot and humid north winds were to bring several days of rain to west and central New Zealand.

MetService said persistent rains and heavy falls could cause rivers to rise rapidly in the Tararua ranges, where there was a warning of heavy rain, which was expected to receive significant rain Monday through Wednesday.

The Taranaki, Kapiti-Horowhenua and Nelson regions were also prepared for long periods of rain and heavy falls, with alerts for heavy rain starting Monday.

The hurricane-force winds from the northwest were to affect the regions that are in the shadow of the ranges.

Strong wind clocks were installed for Wellington, Wairarapa, Marlborough and Canterbury High Country.

According to WeatherWatch, the biggest contenders for reaching 30 ° C on Tuesday, and possibly Monday, are:

Northern region

Northland would have the added aspect of humidity with subtropical winds, WeatherWatch said.

Whangārei was expecting a high of 28 ° C on Tuesday, but Humidex’s temperature, or “feels like,” is probably 32 ° C.

Hawke’s bay

Hawke’s Bay appeared to be the hottest, with overnight lows on Monday night / Tuesday morning around 18 ° C to 20 ° C in the coolest part of the morning, which was between 5 a.m. and 6 a.m.

WeatherWatch said the shadow highs on Tuesday would likely be in the late 20s, with Hastings tilted to hit 29 ° C.

He said it was possible that inland places could get a few degrees higher than that.

Canterbury

Canterbury would be more on the edge, with a thicker cloud cover stretching over the Southern Alps at times and most places weren’t quite in that subtropical flow.

Still, mid to late 20s highs were possible, WeatherWatch said, so 30 ° C was not out of the question when a north-northwest wind is in play in December.
