BRRRR: The southerly engulfs Mt Grey.

Although Christchurch was treated to a warm autumn morning today, a cold southerly change has dramatically dropped the temperature this afternoon.

MetService meteorologist John Law said Christchurch's temperature had dropped by 10 degrees Celsius in the space of an hour.

In about a minute just before 2pm, the temperature dropped by about 6C as a southerly front came through.

Between 1pm and 2pm, Law said the temperature dropped from 21C to 11C. With wind chill, he said the temperature this afternoon was closer to 8C.

This morning Christchurch was treated to a warm morning for late autumn. At about 7am on Wednesday the temperature was sitting at about 0C, but this morning the 7am temperature was 14C.

Law said temperatures then rose quickly, accompanied by a "blustery north-westerly".

Queens Birthday weekend would be dry for Canterbury, but with cool nights and possible frosty starts.

Law warned those running in the Christchurch Airport Marathon on Sunday that it would be a chilly start to the morning.
