......so why is California burning?
Fuel buildup from the very wet summer followed by autumn dryness. Lots of dead grass around to burn. Plus its a typical La Nina USA pattern to be cold in the east and warm in the west. Probably not such a good snow season in the Rockies, pretty epic in the Appalachians.

Its the winter nearly a year ago they had the good rains

Good amount, anything below 20mm doesn't do a lot, gone within a day or so

Hearing rain on the windows and the roof at the moment - very refreshing sound

Possibly an isolated supercell/large hail over Gisborne region later tomorrow.

Had a brief heavy shower here around 5am, nice to hear! First rain of the month. Only 2mm though.

There was some TCu around first thing. Looks like a fine day for Auckland with a southwest breeze, the afternoon showers will be well north.

Front breaking up by looks, might get something later on but missing the bulk of the rain on the front here maybe

Starting to doubt if any rain will make it here today. Happy to stand corrected!

Gone easterly so maybe a little convergence going to happen

Aw man, gis some rain! This anaemic drizzle won't do.

Razor · Unread post by **Razor** » Tue 12/12/2017 11:53

Nothing in the central city yet. Only a light drizzle at home. 0.2mm at airport. Doubt it will reach the 1mm required to break the 'streak'

Light rain here for the last 20 minutes but just 1mm so far.

Looking very good for rain in Canterbury tomorrow, moist onshore flow, cold upper trough crossing.

NZ Thunderstorm Soc · Tue 12/12/2017 13:21

Most welcome on and off drizzly showers here since about 6am this morning.
7.9mm to 1pm.
First decent drop for 24 days here.

Beautiful summer afternoon here, sunny 25C, nice SW breeze blowing.

Interesting GFS run for 11/12/2017 18z for December 19th / 20th. It's put together a 969 hPa bombing surface low attacking the east coasts of South and North islands. With current the SST's, it would be an warm air advection machine. Needs to show up a few more times and on a few more models to be taken seriously but one to watch

Razor · Unread post by **Razor** » Tue 12/12/2017 14:46

Still not a since drop of rain in the central city today as at 2:45pm

I see what you mean... way too far to really get hyped about interesting picture anyway

6mm from the convergence this afternoon. Great to smell the petrichor at lunchtime.

Def one to watch! Could see some significant if not very brief heavy rain.

Thank you for using this interesting word, I've happily followed a bunny-trail of research into it now

No rain here today apart from a spit or two

melja · Unread post by **melja** » Tue 12/12/2017 18:23
