What's your opinion on cloud cover tomorrow John? Do you think there might be alot of high cloud or mid level cloud about at all?

Cheers

I think there should be an increase of high to midrange cloud as the day wears on. Nothing really spectacular

Yeah, pretty much what I was thinking. Thanks.

Abit foggy here this morning rather cool too with that SW blowing.
Nice CB in the Tasman just off SE Australia auckland tracker picking up strikes from further out at sea that way could be from the CB quite big though another weaker one closer satelitte below.

A bit thundery is the Tasman sea as cold air and mild moist air collide.
Should be some big blow ups out there in the next day, will they reach NZ though?

I note the Chch airport reporting cumulonimbus clouds, where!? I can't see a thing with all this low cloud about! Looks like a strike has occured just off the West Coast (around 15 minuted ago), could it possibly be the aeroplanes reporting the clouds?

Yes Steven, should be some showers tomorrow in the Waikato then moving up to Auckland later on with a few heavy showers at times within that trough system extending out into the Tasman. Will it turn thundery? Hope so!!

Cheers.

Aaron, I think you are misreading the comment at the end of the metar, VCBR which means mist in the vicinity (BR is the code for mist, from the french for fog, and VC being the prefix meaning in the vicinity, as in VCSH for nearby showers etc). There should be plenty of internet pages with the Metar codes on them if you need to brush up

And, the rules are quite strict, the metar can only report what the observer can see or measure, so if planes could see CBs then that doesnt qualify them to be reported in the metar.

I didn't actually read the metar, it was just the NOAA website. Perhaps the computer they are running is missinturpreting (sp?) the METAR. This is what it said:

Wind from the E (080 degrees) at 6 MPH (5 KT) (direction variable)
Sky conditions mostly cloudy
Weather Cumulonimbus clouds observed
Temperature 53 F (12 C)
Dew Point 48 F (9 C)
Relative Humidity 81%
Pressure (altimeter) 29.83 in. Hg (1010 hPa)
ob NZCH 270400Z 08005KT 020V150 15KM SCT014 BKN180 12/09 Q1010 TEMPO FM0500 3000 -DZ BKN008 RMK VCBR

Cumulonimbus clouds observed! Perhaps it's wrong then? Oh well. You might be able to see it if the link is still up. It's here: http://weather.noaa.gov/weather/current/NZCH.html

It does say BR as you note in the METAR, oh well. I'm not sure? Thanks.

Cheers

Gary, that wasn't you trying to awaken Frankenstein this morning was it? lol. Looks like there were a couple of strikes near you early this morning (5am?). Did you hear or see anything?

Cheers

The southerly was a bit stronger than expected out on Banks Peninsula; we had some hail, plus a slight dusting of snow on the tops of some hills. Chch (Hillmorton) must've got a shorter period of precipitation, with 1.8mm this morning, most of it in 1 hour.

Willoughby · Unread post by **Willoughby** » Wed 28/09/2005 16:09

Heavy rain has eased now as well as the northwester.

At 10am: Napier 22c

3pm: Whangarei 21c, Auckland (ap) 14c

The wind was quite gusty early on, up to 55km/h around 6:30am. I got to work before the shower came through. Temperature dropping now 6.4C and calm.

After a frost in exposed areas, there should be a lovely fine day tomorrow before the next onslaught

Well only got down to 1 C last night so no frost,

EDIT: actually airport had chch down to -1C

NZstorm · Unread post by **NZstorm** » Thu 29/09/2005 10:31

An air temp of 1C would equal a ground frost.

The grass is typically 2C to 3C colder than the air.
