Two Tasman Lows Bearing Down, Rain on the way

Persistent low cloud and drizzle in Chch this afternoon and evening. Not exactly pleasant, but I'd rather have this than what Tauranga's getting.

Meanwhile Buller and Westland seem to have gone back to summer, with 20-21C maximums today.

Good session from 1900 - 200Hrs last night with a string of Cbs banging away - unfortunately I couldn't get out to play

Good to see you made it through with only (another) wet carpet, Snoops.

It's wierd out there this morning, very low fast moving cloud? With a thin high level cloud, No rain whatsoever, but warnings we can still expect up to 100mm more in the next 12 hours. Apparently there will be another system with lots of rain through on the weekend.

Man, this place just plain old stinks.

From the MetService site, total of 554.8mm to 9am this morning

Fine morning here, but cloud has increased now and showers are on the way soon.

Showery tomorrow, mostly cloudy on Saturday, wet from Saturday night and strong westerlies from Monday

More murk and drizzle this morning. No precip now, but no break in the sky either.

Showers on the way shortly, maybe heavy locally. Temp a warm 20c, but lower humidity than yesterday.

Does it look very active from Auckland, guys?

Just a normal Summers day here.

Warm and Sunny.

Here's pic I took YESTERDAY from Mt Roskill of a Cb over Brians house out there on the Manakau Heads. Could here Thunder from this cloud.

Manukau heads obs · Thu 19/05/2005 19:00

you guys have tempted me back to post
great photos of a great thunderstorm we had here!
17mm i have from one report that fell in a short period of time
heaps of lightning and thunder
25 knot outflow winds too boot (on a otherwise only 10 to 15 kt wind day).
what wa amazing was how fast the whole thing developed, especialy the 2nd cb line a bit further west...
there was a weak sea breeze coming in the heads that helped the whole thing go up so quickly I think..we ended up with a westerly wind...and we were right on the edge of the rain....but it weird becuase the wind looked like it would blow it on to us...but it was actualy moving north/south...
afterwards quite a good NNE blew...like it was sucking air into it...probably was...

incredible rain in the BOP yet again...unbelievable sights on the TV!

grass jumping out the ground here now

smiles here at least

Temp a warm 20c, but lower humidity than yesterday.

The lower humidity today removed the instability.

I saw the t/cu inland today but didn't expect anything due to the drier air today. Instability is a fical thing.

Looks a change to moderate WNW or NW tomorrow with the odd heavy shower

Persistent low cloud in Chch (but no more drizzle in afternoon, at least not in central city and Burwood) turned into a real pea-souper earlier this evening, but it's now breaking up and I can even see a few stars.

Yes Brian, looked like a good Thunderstorm over your way yesterday afternoon. Later in the afternoon I noticed another very big Cb W/SW of here but I think this Cb was SW of you and may be out to Sea.
Took the photo below at 4.20pm before low cloud rolled in.

But the low cloud and drizzle returned later in the evening, though it's just cloudy this morning.

Cloudy today with isolated light showers. NE breezes and very warm again, 21c

Northeast winds will be quite strong come Sunday morning

Looks like BOP could see some more rain this Sun morning easing during the afternoon/evening. 50-100mm possible, get ready!

Not sure about thunderstorms this time though, smaller risk if anything is all I can come up with at the moment than the last low.

Cheers.

Warning now cancelled, thanks to an awesome display by the mighty Crusaders.

Thanks Aaron, I'm leaving the sandbags in place & haven't bothered cleaning up the silt outside for now.

The combined dehumidifier extraction overnight was 70 litres inside... Things are staring to dry nicely now. The Rotating direction fans in addition to the dehumidifiers have made a huge difference.

Not sure about thunderstorms this time though,

Should be some strong convection within the system due to very moist air, so thunderstorms look on the cards, particularly for Northland/Coromandal ranges. Met Service reflect this risk in there latest convective outlook.
