Canterbury is in for a mostly fine Show Weekend, with dry weather expected for Saturday’s races before cloud and possible rain arrive later on Sunday.

MetService meteorologist John Law said Christchurch could expect a little morning cloud on Friday before conditions cleared, with a high of about 18C.

While temperatures would be lower than Thursday’s, the outlook was promising for people making the most of the anniversary weekend.

“I think there’s still plenty of dry weather as well. The only thing I will say is keep an eye on the forecast for that second half of Sunday.”

Weekend racegoers could look forward to a marked improvement on the weather than earlier in the week.

“The good news is Saturday is looking much nicer than the weather we saw at the races on Tuesday,” Law said.

Saturday was expected to stay dry with plenty of clear sky, with temperatures reaching the late teens or possibly the low 20s.

Cloud was expected to build later on Sunday, with rain more likely inland around the Canterbury foothills. Some patchy rain could also reach Christchurch.

Law said conditions should improve during Monday, although the working week could begin with some cloud.
