FROSTY NIGHT ON THE WAY FOR MANY – MOSTLY FINE & SUNNY TUESDAY

(WET & COLD WEEKEND POSSIBLE – POTENTIAL FOR HEAVY RAIN & SNOW ABOUT THE RANGES)

Good evening. After a freezing start this morning, the day has played out mostly fine & settled across the region. Most towns & areas struggled in single digits, with 9 degrees a common ‘high’ across the Canterbury Plains & coast; through the interior & High Country Castle Hill Village, Twizel & Arthur’s Pass struggle to 6 degrees, after dipping to negative 6 this morning.

We’re heading into a relatively settled next few days, nothing to threatening, but our eyes are now fixed on the potential for heavy rain & snow about the ranges this weekend.
