[NZ Thunderstorm Soc]

Only down to minus 0.6C this morning, with not much frosting around here but more so around Templeton and some parts of the city might have got a lower reading as there were reports of icing on car's windscreens.

[kiwisk8er]

Our first negative frost of the year, currently -1.5C at the bottom of Tawa Valley, Wellington.

[Richard]

Down to -4.5deg here

[Richard]

Only a light frost on the grass today with dryer air and a -2C minimum.

First negative for the year here. Just -0.7. The wind never fully died away. Would have been much colder otherwise.

[trickytiger]

-6.2deg frost here, made milking a bit longer as froze everything at the shed

A little cooler over here, with -1.3 C (Air) and -2.2 C(Grass), as Jamie said Wind never dropped away.

[Andy]

Hard frost again with -7.5 deg

You seem to get a lot colder on calm clear nights then what I get even though I'm hard up against mountains and at a higher elevation..

Was -5.6 this morning and -3.4 now. Has been below freezing since 5.20pm

[Simon Culling]

Interesting to see your low overnight temperatures under high pressure. The METARS for Christchurch Airport give a minimum of -2*C, but this is followed by a day maximum of about 12*C. Here in the UK under similar conditions (and I appreciate further away from the equator + with a lower sun angle) we would see max temps of up to around 5*C and nearer freezing if the o/night lows were nearer the -7*X experienced inland by Richard + Andy. What day maxes do you inland guys get under these clear/sunny set-ups?

This mornings frost is very heavy for this early in the season,gees and we are not even in winter yet,my two gauges in the screen this morning are showing -9.5 and -9 deg doh while i do ask myself why is the nearby recording station at Culverden only showing -5 deg,but how high above the ground level do they have it?,one of NIWA's stations which is 2 kms SE of me have there's what looks about 2.5-3m up https://www.google.co.nz/maps/@-42.8976 ... !2e0?hl=en
Simon - today because the center of the high over us will be starting to move to the east the daytime temps should creep a little higher than yesterday's 12deg, we may get up around the 15deg mark.
