Here’s what is making the weather headlines today.
THUNDERSTORMS TODAY AND TOMORROW
Becoming unstable this afternoon and tomorrow afternoon with a chance of thunderstorms and downpours for the North Island, especially for inland hills and ranges.
A risk exists for the South Island too but it is less, today this risk is about the lower South Island for inland hills and ranges. Thursday’s risk is about inland areas east of the Main Divide.
More on today and tomorrow’s thunderstorm risk here.
FEELING MUGGY
The convective activity mentioned above gives a hint that there is good surface moisture about, more so for the North Island. Dew points will likely be in the mid to late teens.
A dewpoint of around 10 degrees is fairly average, 11 to 15 is getting more humid and 16 to 20 is getting tropical. A dew point of 20 degrees is actually very similar air as to what Fiji may get, some North Island regions may reach 18 to 19 degrees today and tomorrow.
WESTERN REGIONS STILL GET BULK OF THE RAIN
Rainfall for New Zealand over the next seven days is looking average to wetter than average, western regions pick up the majority of any upcoming rain but eastern regions don’t miss out totally.
The western theme is mainly be due to the weather arriving in from the west, at first this is mainly a low then fronts in a northwest airflow from the 21st November. Eastern precipitation will mainly be the result of convective activity like the type mentioned in the first article above. But we also have a front rotating over the country into the second half of Friday then this feeds into a low out west on Saturday, at this point the eastern South Island should hopefully get a more sustained period of rain or showers.
The below precipitation percentage of normal map runs through Wednesday 23rd November, red is drier than expected conditions while blue is wetter than average expected rainfall, white is average rainfall.
