I'd expect the mean max to end up in the 19.x C somewhere. I'd be very interested in knowing what the coldest January mean temp record is though (possibly 97?).

Currently 13.4c mean as at Jan 14th the airport site.

With the breezy weather and low rainfall here over recent weeks the garden is getting very dry. Still on track for heavy rain over the upper North Island from late Monday, some downpours and thunderstorms on Tuesday. I will be away so next week so will miss this next system, the garden should get a good drink.

Looks like we are heading back into a simular phase like back in November early December soon.
The W-NW flow with occasional SW, this will see those temperatures back into the mid to upper 20,s.
A quick taste on Thursday before returning again on the weekend.

EC is going for high winds next weekend, while GFS is throwing out hints of a decent thunderstorm set up for the 26th.
Meanwhile the tropics continue to fire up.
A busy few months ahead perhaps 🤔

Indeed, from mid November through later December the MJO took us on a grand loop from phase 2 all the way around to phase 6. The current forecast has us taking the same path in the next 3 weeks. So a similar pattern, but somewhat compressed.

A last! A blue dome day, well nearly. There were a couple of clouds around this afternoon but basically, it was a welcomed sunny day with light to moderate NE winds with 24C the maximum for today. Hope for more sun tomorrow.

A second sunny day: the situation is becoming serious ;-)

Mares' tails streaming up from the south; a chemtrail contrail showing aloft from a passing aircraft, so perhaps a change coming.

11.9°C, expecting 23°C; 1010.6hPa, slight northerly.

Been a few nearby rumbles out in the Gulf earlier this arvo.

Ended up with a very welcome 23mm here since last night. Don't think Akld got much though?

Parts of Northland have had around 50-70mm today by the looks (bringing Kerikeri Aero's 3 day total to 144mm).
Whitianga up to about 70mm so far today...

Only 0.8mm here. These subtropical lows from the North are so hit and miss this time of year. Things were absolutely lush up until the end of December but have really dried out now. Maybe a better chance this Saturday but won't be surprised if same happens again.

The frontal activity later Saturday/Sunday morning could be active with thunderstorms, something to watch.

In Sydney this week, up 35C here today before a cooler change with some weak looking thundery showers.

Fine warm day here today with light easterly breezes. A wee bit hazy though. Up to 25C for a while this afternoon.
Might be a rumble or 2 tomorrow with the southerly change but nothing much to issue a STW.

Brief shower cell around inland Rakaia threw out a couple of strikes just before, looks to have been some hail there too.
Still breezy NE here but can see the southerly signature on the radar coming up.
Probably just a smattering of showers tonight with this front.
Maximum of 22.4C so far much warmer inland with the NW
