National Outlook
Overview: Some showers about early next week but they'll be hit and miss and most places will continue dry and sunny in the main until after midweek. Low pressure is signalled to become more dominant towards the end of next week bringing an increased chance of showers or spells of rain then.
Sunday night: Largely dry and clear, apart from isolated mist patches around dawn. Lowest temperatures 4 to 9 degrees in light to moderate easterly or variable breezes.
Monday: Mostly sunny to begin on Monday but patchy cloud looks set to build through the morning with a few showers breaking out in the afternoon and evening, one or two possibly heavy. Highest temperatures of 16 to 22 degrees in light to moderate easterly or variable breezes.
Monday night: Many parts will be dry and clear on Monday night, although the odd shower can't be ruled out. Lowest temperatures of 4 to 9 degrees in light easterly or variable breezes, with a few mist patches around dawn.
Tuesday: Mostly sunny to begin on Tuesday too, but again patchy cloud looks set to build into the afternoon bringing the chance of showers, some heavy and possibly thundery. Highest temperature of 16 to 22 degrees in light easterly or variable breezes.
Wednesday: Current indications suggest a warm and dry day with variable cloud amounts and sunshine. Highest temperatures 19 to 23 degrees generally, a little cooler in the northern coastal fringes all in light to moderate northerly breezes.
Further Outlook: Still a fair bit of uncertainty at the current lead time, but Atlantic westerlies do look set to eventually return towards the end of the week bringing a greater chance of spells of rain or showers.
