9-14 Feb Subtropical northerly flow, embedded troughs

[NZstorm]

It has brightened up here and no DP is 23.3

I see Gisborne on 29C with a dp of 23C. And even Taupo airport has had a dp of 23C today. Very muggy!

Auckland has been stuck under a low grey overcast for 3 days now. I have 74mm for the event.

Some really heavy rain headed for Coromandel. Getting a heavy burst here currently but looks to be clearing soon.

Been a sticky humid day in Wellington today. Especially once the northerly kicked in. I cleaned the fish tank and refilled it, and since then the outside of the tank has been dripping with condensation.

54mm for the day now, 98mm for the event. Currently warm drizzle

Very heavy rain here, sitting nicely at 60-90mm/hr

? 60-90 mm/hr is pretty high for NZ, was that sustained for long?

No it wasn’t anything spectacular. Had much much heavier for much longer. Was about 10mins and just over 10mm. About 13mm in 10 mins.

Everyone around Hamilton is commenting on how damp carpet, bedsheets, flooring, clothing etc is today and yesterday. Washing that was hung out yesterday still isn’t dry in our hose. Our bed even feels weirdly wet.

Levin had heavy rain, thunder and lightning at around 8:30pm with surface flooding (most of it has receded now)

[David]

Already on 178mm here this month! Looking like another round of rain tonight and tomorrow.

[Razor]

Some significant downgrades and upgrades occurring across the global models on an each run basis. The German high res model Icon just projected a 200 to 300mm soaking convergence zone for late in the weekend from upper to central NI.

Looks to be coming to pass, albeit a day late

Metservice modelling throwing up some insane numbers around Auckland and Waikato tomorrow, 100mm or more in just a few hours in some places

Heavy Rain Warning
Heavy rain may cause streams and rivers to rise rapidly. Surface flooding and slips are also possible and driving conditions may be hazardous.
Area: Great Barrier Island, Coromandel Peninsula, Waikato from Morrinsville eastwards, Bay Of Plenty, Rotorua, Taupo and Tongariro National Park
Valid: 44 hours from 8:00pm Sunday to 4:00pm Tuesday
Forecast: Periods of heavy rain till Tuesday afternoon, with thunderstorms possible. Expect a further 200 to 250mm to accumulate about the Kaimai Ranges and Taupo and 150 to 180mm elsewhere. Peak intensities of 20 to 30mm per hour.

Well they obviously don't trust their own model as the watches are now lifted for Auckland/Waikato...

Only partially lifted- still in place for Taupo and eastern parts of Waikato, Waitomo and Taumarunui Tuesday

[David]

Yes, didn't read it correctly. Should have said watches lifted for Auckland/Coromandel, both areas where their 3 day model shows some quite large accumulations.

Currently 24.6c, 23.3c DP and full sun. Grass growing rate is 5mm per hour

4000 km elongated trough is linking up with TC Gita and receiving an atmospheric river running around 50mm to 60mm, moving slowly moving westward towards central and upper North Island tonight. This could be the mother of all convergence zones if it lines up tomorrow. Some models think big, some not so big……. As razor mentioned, MS is now talking it up and their modelling is juicy. Where ever that trough stalls, it's going to be a narrow tropical water slide on the east side of it.

When the trough linkage to TC Gita is disconnected late tomorrow night, Gita will become a wild independent Cat 5.

Auckland similar to Darwin right now but it is 7.20am at Darwin.
Auckland 25C,dp 23C Darwin 25C, dp 24C
Christchurch is humid today, current 26C, dp 18C, Jeffs station.

[jamie]

26.7 with a 23.5 dew point. It’s hot!

That's crazy! I remember the DP spiking to over 24C when I had the weather station - but it was only a short time when it was above 24C.

People will be feeling it I guess - not many places have AC.

[David]

26.7 with a 23.5 dew point. It’s hot!

Similar on my station. Today's max dewpoint is 23.5C, my station record is 23.7C back in 2011

[spwill]

The general Auckland dewpoint is around 23C, possibly up to 24C at times in places. current temperature around 26C

[jamie]

Just keeps getting hotter. 28.2/23.1. I think today is the most uncomfortable heat we have had all summer. Two degrees warmer but the DP 2 degrees lower didn’t feel as uncomfortable as this.

[harleyb]

Same here. A PWS a block or so from here just hit 31.7 with dp 24.1... ugh.

Currently a 23.9c DP here. Record for me.

Atmospheric river running hard now from the tropics, with the flow shifting west. It's going to go big where ever that squeeze zone ends up. http://tropic.ssec.wisc.edu/real-time/m ... anim=html5

Cicadas are going nuts again, somethings brewing

[David]

Currently a 23.9c DP here. Record for me.

My station broke it's all time high dewpoint record by 0.1C. It got as high as 23.8C before dropping back a little bit.

[melja]

I've got cicadas here in my garden in Rangiora North of Chch too which is unusual for here.

Do tend to get a few cicadas here in summer but none heard this summer for some reason.
