A COMPLEX WEDNESDAY – a few afternoon showers for parts of South and Mid Canterbury

Good morning. It’s a clear and cool start for most of Canterbury, with areas of light frost. We’ll see contrast across the region today, with some afternoon showers about southern areas and mostly drier conditions in Mid and North Canterbury. Winds tend south-westerly during the afternoon south of Christchurch. Temperatures peak around 14-16 degrees for most, cooler about South Canterbury, with more extensive cloud cover and south-westerlies developing. 

Please check your local CWU town forecast for specific, locally moderated details today, as conditions will vary considerably across the region.

OUTLOOK

The second half of the week looks drier and more settled overall, with just the possibility of cooler southerlies and showers on Sunday.

Early and middle stages of next week look mostly fine, before an increase in rainfall chances late next week.
