Hi phill what’s causing Nelson’s showers next week even though we have high pressure?

Hi Jet, end of next high pressure moves east of NZ and just before the next big high moves in to the country there is a small area of rain/showers trapped in between over the South Island for a time.

Cheers Josh. Funny you say that, as this is the third time in a decade I’ve finished covering a severe weather event and then juuust as it ended and everything goes quiet, a tsunami alert is issued for the entire Pacific 🙂 No rest for the wicked!

Hi Josh, yes modelling was really good with this event, definiely a soaking for many regions in the north. There’s a little bit of chatter about La Nina later this year, but for now it looks NEUTRAL still until December.

In the WeatherWatch app, the ‘Day’ and ‘Night’ can be translated to ‘maximums’ and ‘minimums’? Why does the Day and Night forecasts in ‘Outlook’ and ‘Temperature Trends’ differ by a few degrees for the same location sometimes? Even the Day and Night temps within the Trends section contrast with the points in the graph by about 1 degree. Why are these discrepancies?

Hi there, we’d need to see an example of this please. Can you please send a screenshot to news@weatherwatch.co.nz of the two different temperatures for the same location (need the location in the screenshot too). In the past when this has happened it’s because it is finding two locations in a similar area (ie, the top of a hill or the bottom of it, in the same area). It’s a rare issue, but it’s the likely cause.
Kind regards
