Ok maybe burn was a poor choice of words, "dissipate" ?

Sounds like a jim hickey term.

Yea down -4 before midnight, but a warm -1 now at breakfast. Thick high cloud and a northerly developing here.

Coldest this morning between 8-830 in chch -2c

High cloud here so not as cold as i expected 2 degrees at 7am overnight low of -5.

Down to -3C at 7am this morning, but ice on top of ice from yesterday made for a bad morning on the roads with lots of accidents due to ice.
One near Rolleston involving a few cars, one between Ohoka and Swananoa on Tram Road which i traveled up with one car and one 4 wheel drive involved head on by the looks with black ice in the area.
One up near Oxford a truck went through an intersection but couldnt stop because of ice and hit a car.
Two outside work both hit the same bridge where black ice was, heard them both one at around 10:20am the other at midday.
Bridge concrete wall taken out on impact with one the crashes.
Any proper police reports on these accidents would be good if anyone knows, as i know there were alot more too around Canterbury.
Even i found by dropping my speed my car slid off a few times, so it seems it wasnt the fact of a heavy frost but just yesterdays frost didnt melt enough and was layered again by this mornings.

Yes, it was slippery ride to work this morning as the back of the truck swung around on icy bits. A car has rolled into some trees after hitting some ice at 'The Whisky Bend" in Jones Rd. near Weedons.
Even though the frost wasn't as severe as the previous two mornings, it would be the accumulation of ice in sheltered areas which would give the roads the hazardous conditions.

There's a trend where each mornings frost gets lighter,the same again today too,only -3.

-3.5 this right now. should get colder.

Maybe inland but not here in rangiora, had -3.4C tuesday and -3.2C today.
Have had a ground frost every day this month with -9.2 the worst.

Managed 1.9 here this morning despite a light breeze.....very light ground frost in open areas

Ended my run of 4 decent frosts this morning with the temp only dropping below zero just after sunrise. Previous 4 mornings were -3.9C,-2.9C,-3.6C and -3.8C on Saturday morning. Yesterday morning was Nelson's aero coldest morning as they got -2.5C.

Air min yesterday in Upper Hutt was -6 with a gmin of -10C ..This morning was -4 with -7C on the ground. Chilly Willy stuff

Did you have cloud this morning???,i could see a bit of low stuff towards the eastern hills.

-1 in rangiora this morning but it was a very frosty frost with the worst ice on the roads around here and kaiapoi this week, so thats a frost all 15 days of this month so far.
The roads round here are starting to look like central otago with the amount of grit going down

No cloud this morning in ChCh. Clear, light breeze and much warmer than Richard and SSW, and rangiora. By a number of degrees!

Quite amazing really

There was ground-frosting in wind-sheltered areas away from the NE this morning, but no frosting in open areas.
Plus figures overnight here.
