Early next week, high pressure still dominates, but generally colder air becoming entrained into its circulation from the north, which sees lower temperatures on high terrain. Small amounts of precipitation, occasional showers or snow flurries. Later in the week, a stronger and colder northerly may develop with snow and hail showers becoming frequent in the north and down coastal extremities elsewhere.
