KEY POINTS:
If you thought last night was the coldest night of the year so far, you were right.
Now here's the bad news - tonight is going to be even colder.
In what could be the coldest night of the year for some people, frosts are set to spread as far north as Auckland and possibly Northland tonight following a weekend storm that brought ice and snow right across New Zealand.
The Radio Network's independent Weather Watch Centre is predicting widespread frosts across Auckland and some light frosts in sheltered areas of Northland.
Head weather analyst Philip Duncan says roads will again be dangerous through some parts of New Zealand tonight and tomorrow morning, however conditions shouldn't be as bad as this morning. "Today many woke to black ice on their roads as far north as Waikato.
Thanks to plenty of sun today the risk will be lower Wednesday morning but the risk is still there. If you're driving early tomorrow morning take extreme care".
The Centre suggests placing newspaper over your windscreens to prevent ice on the windows. "For Aucklanders ice on the windscreen can be a bit of surprise! Quickest way to crack your windscreen is to pour hot water on it. Keep windows covered, or park under a tree".
Duncan says the coldest time of the day is shortly before sunrise which is why frosts often form around 7am just as people are leaving for work.
