There was a chance of a few showers in inland areas but most of the region would be fine, she said.
The scattered showers would be a result of the broad low moving across the country.
There would be a low of 14C and a few northeast winds which would only feel a "little fresh" on the coast.
Tomorrow will start off with some inland rain with high clouds elsewhere.
Occasional showers might spread across the region due to a chance from northeast to northwest winds but they wouldn't last long, Ms Murray said.
They would clear by the evening and Monday would be fine with a few high clouds, she said.
Temperatures would again reach 23C both tomorrow and Monday but would drop to 12C overnight tomorrow.
The rest of the week looked relatively mild with a fine focecast for Tuesday and high cloud increasing on Wednesday and the chance of some rain.
