Wednesday: "Scattered light showers in the morning will tend to fizzle out by the middle of the day becoming drier and brighter during the afternoon with long sunny intervals developing. Highest temperatures of 14 to 18 degrees in light to moderate northwesterly winds.
Wednesday night: "Cloud will quickly extend from the west early in the night with patchy outbreaks of rain following later in the night. Another mild one with lowest temperatures not dropping below 8 to 11 degrees with some mist and fog patches developing in light west to southwest breezes.
