Can certainly see some evidence of that from the city. Managed 27 degrees here today, warmed up early on then at about Midday cooled off to about 24 degrees before warming up to 26/27 again later in the afternoon. Now down to about 21 degrees.

Edit: Now a Severe Thunderstorm Warning in force for the area north of Gisborne City by the looks of things. Issued at 6.02pm by the Met. http://metservice.co.nz/public/weatherW ... nings.html

AWESOME!!!! is this the first ever thunderstorm warning? There is a lot of white and green on the radars. Im even picking up some strikes from here. There are a lot of ranges between here and there so they must be quite strong strikes.

Yes, this was our first official Severe Thunderstorm Warning. The new Mahia radar did a great job and showed that this was one of the strongest storms we have seen on radar anywhere. Storm tops were 11 kilometres as it approached Tokumaru Bay and it indicated hail in the 15-20mm range for a time.
It will be interesting to get some weather reports.

A very high tropopause today, 14km over NZWP! Quite a subtropical airmass over over us today.
And a little bit of upper level cooling has occured over Gisborne ranges for those cb's to fire. Hopefully these storms are a sign of things to come!

Interestingly the radar shows some isolated heavy showers or Thunderstorms in the Western Waikato at around the same time (the red bits).

These are direct from M/S: http://www.weatherwatch.co.nz/content/t ... s32deg-bop

Cheers!
Yes, I did see that, but thought the use of a comma instead of an 'and' might've meant that Kawerau was part of Whakatane, particulary as Kawerau wasn't on the list. #-o Plus I would've expected Kawerau to normally be a little higher than Whakatane, although with rounded figures that could still well be the case. Either way, it's most likely a Nov record for Whakatane and at least an equal Nov record for Kawerau (bearing in mind a lack complete records). :smile:
Myself wrote:I clicked on Whakatane earlier and the 4PM observation said 30C, with NW wind at 15km/h. 1010hPa, 47% RH.

Kind of eerie the stats you post....November 24th......strong El Nino......followed by legendarily hot summer?
Hmm... must've still had the 3pm figures showing when I clicked on, despite it saying 4pm.

And yeah, the 1997 dates are kinda spooky... 0_o

Paul,
Can you attach the warning to the forum (and the graphics) if you please?
I completely missed it. ](*,)

Here is image of the t-storms that started to fire around Gisborne.
Its from the Aqua/MODIS satellite, which would have taken the images around 3-4PM.

Elevated terrain would have been a key factor in the development of the storm late yesterday. The reason storms develop a lot more easily over the high country is because convection requires less of a dewpoint to develop the higher up you go. The storm was likely a short lived supercell.

I see the moisture starts pouring back onto the country by Saturday with some thunderstorm chances likely to result, more particularly early week as a shallow low crosses. Fingers crossed the low doesn't pass north of us which can happen when high pressure is to the south.

high pressure is to the south
looks like a flip flop reversal in the weather pattern for later next week
high pressure to the south and low pressure to the north....will make a big change from the last 6 weeks!

Nice sunny 21.1C here today.

Just looking at yesterday's BoP stats and it looks as though not only was Whakatane's 32.1C a Nov record, but so was Tauranga's 28.6C, beating its previous Nov record of 28.3C set in 1922.
(Tauranga's second highest being 28.1C in 2007 & 1940 - third highest 28.0C in 1997)

Kawerau's 31.9C was just shy of a 32.0C recorded in 1980. However, for the few years prior to 2009, a practice of rounding Kawerau's figures seems to have been adopted (still happens with sites like Alexandra and Culverden) and there were 2 consecutive days in Nov 2007 when Kawerau recorded a rounded 32C.

And yes, yesterdays high temps all appear to have peaked between 3pm and 4pm. :-#

Strong gusty NWer from about 5pm today, i see on the news weather webcams it was still NE in Chch is that correct?.
The sun was quite strong today got up to around 26C for much of the day with a very light NE, then once the NWer came or just before it with no wind at all it rocketed to 31C.
Back to 28C now but still strong NW.
