WESTERN NSW has experienced another string of cold nights and dry days during the past week, although a change is on the way.
A slow-moving ridge of high pressure caused a prolonged run of chilly nights over western NSW during the last week.
Parkes Airport registered minimum temperatures between 1.5 and minus four degrees Celsius between last Thursday and Wednesday this week, which is well below the June average of four degrees Censius.
Further south and higher up, Wednesday morning's minimum temperature of minus 6.9 degrees at Perisher Valley was their eighth consecutive morning below minus four degrees.
This was Perisher's longest spell of mornings this cold since 2015.
If the mercury reaches the forecast low of minus four degees Celsius on Thursday, this will be Perisher's equal longest spell of nights this cold since 2010.
Looking ahead, the stable weather that produced cold mornings during the last week will give way to a cold front this weekend.
The front will cause rain and thunderstorms to spread across the state's western, central and southern districts on Saturday and Sunday morning.
Some areas of the southern inland could record more than 30 millimetres of rain from this system, particularly about the ranges and south west slopes.
More widespread totals of 5mm to 10mm are likely over the southern districts of NSW, on and west of the ranges.
Drier weather is expected to return early next week as the next high pressure system crosses the state.
This will likely bringing frosty nights back to some areas.
