Thunder possible Northland/north Auckland May 8th to 9th

NZstorm · Unread post by **NZstorm** » Wed 08/05/2013 07:21

The upper trough has brewed up some convection out over the sea just the west of the North Island.
A frontal band will move onto Northland this morning and drift slowly south to reach north Auckland this evening according to gfs. Dewpoints this morning across Northland are around 14C which is supportive for at least isolated thunderstorms given 500mb temps -23C. CAPE 400j/kg. As the front is slow moving some eastern parts of Northland could get a decent amount of rain.

Hard to tell how much rain is coming our way, but I am just within the limits of the Metservice moderate risk area tomorrow

I'm surprised how quickly the rain is coming toward Auckland this morning, faster than any models had been indicating.
Skies looking dark to the north.

The line to the north has become more active this morning with thunderstorm activity.

Feels quite chilly here with moderate rain and very dark out there! No wind...

Raining pretty well at Auckland uni
And I'm here with no umbrella because I thought the rain was due tomorrow

Darkening skies to our north here. Wasnt expecting the rain to be this far south so early. Its really building fast too from what the radar is showing.

You're in the fireing line tomorrow by the looks david. I wouldnt say your on the edge. Looks juicy indeed with the hail size.

The northland radar is supposed to be opperational around July with site works due to commence around June once final approvals have been provided. Thismorning would have been a good day to have it up and running.

The front is clearing upper Northland, more aimed at Auckland/North Auckland now.

I see Ricky's weather station rain gauge not working.

There is a new weather station online in Kingsland now.

Yes, just had a look and there was a large bird poo right down the middle! measured out about another 3mm accumulated in the funnel..
All good again now, updates the figures.

Make that an extra 10mm just calculated it...

MetService's severe thunderstorm watch now extended to include North Auckland this evening. Very wet and gloomy here in Takapuna.

Really that's quite a significant reading - I'm south of Kerikeri in Whangarei and weve only had moderate to light steady rainfall over a 3 hr period since midday today.
There has been a couple of heavy downpour's that lasted for a min or two at the most. I thought nortland (Whangarei) would be clear of all the heavy stuff and Auckland was going to get all the rain.

Takecare.

Cb's have been developing over Northland today, they can bring localised very heavy rainfall. The radar shows more developing now inland from the Bay of Islands

Thanks, though the rainfall reading seems quite low

Might get some heavy falls this evening, looking at the radar

Very eerie sunset here, peeking through a gab in the cloud to the north west and lighting up the towering clouds Just to the east.

It's been interesting watching the rain area shrinking in on itself on the radar, a few hours ago I assumed it was going to rain most of the night. Up to 31mm, easing off here now.

00Z gfs not showing too much precip for us overnight.

We will have to see what can develop tomorrow before the system shifts away.
