In amongst a fair bit of wet weather, we should see two bursts of snow this week, a nice little refresher in the last week of the season.
The colder air arrives early on Wednesday and lasts for much of the day. This may deliver 5 to 10 cm, locally more.
It warms up slightly later on Wednesday at lower elevations, but we aren't done, with the coldest part arriving on Thursday. Another 5 to 10 cm is possible, locally more.
Light snow showers may continue on Friday before it dries up (and significantly warms up) for the weekend.
