Looks like an interesting low developing in the Tasman Sea next week.

That’ll be yet another East Coast Low that’s going to flood my dad on the NSW east coast for the 4th time this year… the model numbers are pumping out huge amounts of rainfall for him so it will be interesting to see what impact it has on NZ.

Frosty start to the month in Chch, plus a dusting of snow on Mt Herbert. (1st I've seen this year)

Snow potential looks to be increasing for mid to late next week. Ruapehu may get the fall of snow it needs.

Frosty start but icy underfoot this morning from last night's overnight rain. Fine day eventuated with light winds.
Today's maximum was 11.1C.

After a frost, another fine day eventuated with not much wind, calm really
Here is a photo of tonight's sunset to make this posting more interesting.

looks like the North tasman sea is going to be a low factory this month!

Fog here this morning.

Snow for the SI high country later in the week.

A fine blue dome day here today except for the sunrise and sunset.
Calm or not much wind. 15.1C for today.

Dont see 20C forecast in July very often as Whangarei and Auckland have for this Friday, when it's not due to a foen effect.

Here it is out my front window! It has ever so slowly crept north throughout the morning. I wish it would hurry up, it’s quite chilly!

Reached here by about 4.00pm

Covered the sky here this morning withholding the cold temperatures from the frost overnight but cleared away to the north and the sun warmed the day up.

Another fine day, especially this afternoon, being blue dome with a light NW blowing.
Milder than the past few days with today's maximum being 15.4C today. Slight frosting overnight on the grass and windscreen of the truck.

a warm night here for July (after a cold start to the day), due to the passage of a warm front in the evening
(15c during the night)
40mm of rain here yesterday

High of 15.0C here yesterday recorded around 8pm, followed by a low of 12.0C this morn around 2am.
33mm of rain here yesterday.

Wettest places from MS yesterday (mm):
49 ... Whitianga Airport
38 ... Tauranga Airport
35 ... Whenuapai
32 ... Auckland Airport
30 ... Paeroa
28 ... Hamilton Airport

Starting to suspect my station has been under reading on rainfall somehow (was calibrated years ago so not sure how).

Put the manual gauge out for this latest event and it picked up 35mm. Weather station showed 26mm. Pretty big discrepancy!

36mm here yesterday.
Very moist air showing up for Friday, dew point will be around 17C here, some of the showers might be heavy on Friday but upper level temperatures are very warm this week.

I run my manual one within 30m of my electronic gauge all year round so I am always on top of an incorrect reading. It can vary massively tho. I can have +/- up to 5mm on rainfalls like we had. For example yesterdays event was 34mm electronic and 30mm manual. However it can easily go the opposite. On a event 70mm it can get close to 10mm difference each way.

@David
the Davis station does tend to under read, over time
I have an offset

48mm rain yesterday. Was steady from around 3pm to midnight with nothing especially heavy, just consistently persistent.

Apparently it was a warm day in Timaru yesterday with 18.3C. Not that warm here even though a light westerly was blowing.
