COLDER SOUTHERLY CHANGE ON COURSE FOR THE WEEKEND – rain & snow feature

Good evening. It’s been a mostly cloudy day across the region, with occasional sunny periods. Nor-easterlies were fresh and occasionally strong about the coast between Ashburton and Amberley. It was milder in North Canterbury, with Hanmer Springs grabbing top spot, with a pleasant 16.1 degrees; the full list of the daily ‘highs’ below.

The remainder of Wednesday will be mostly cloudy, with spill over shower risk in the east. We expect more sustained and heavier falls about the Main Divide/Headwaters. 

• Please check your local CWU town forecast this evening, for specific and moderated rainfall chances and totals.

OUTLOOK

Our Thursday will be mostly fine, bar areas of cloud and isolated showers before midday. Expect milder afternoon conditions, with foehn influence. Fine and slightly milder weather continues on Friday.

Rain and snow chances look set to increase over the weekend, with the potential for low snow.  This period is coming into town pages, with more detail over the next few days; general changes have taken place on town pages, with sleet and snow forecast for many areas. Members keep up to date with our ‘Live Weather Feed’ for on-going information. A road snowfall warning is also in place for our alpine passes late Saturday and Sunday. Snow may be heavy in some areas and we may see snow to low elevations for a time, especially north of Porters Pass on Sunday morning.
