TODAY - Tuesday 11th December

Tuesday will begin mostly cloudy and mild, with just a few spots of drizzle, mainly appearing along south and east coasts. However a spell of persistent rain will move into Munster and Connacht during the afternoon, turning heavier here towards dusk. The band of rain will slowly push into other areas later this evening, whilst a clearance will develop in southwest areas. Highest temperatures of 9 to 11 degrees Celsius. Southeast winds will freshen, backing westerly later in the day and easing.

TONIGHT - Tuesday 11th December

Many areas will be wet early tonight as rain extends northeastwards. Staying wet for much of the night in the north and east, though the rain will gradually ease off. Whilst a clearance will develop in other areas, mist will thicken into dense fog in parts; and where skies clear, frost will set in. Lowest temperatures of 0 to 6 degrees Celsius, in near calm.

TOMORROW - Wednesday 12th December

Some lingering rain will affect east and northeast fringes into Wednesday, with frost and fog clearing other areas. Otherwise staying dry across many areas with some winter sunshine, however southeast breezes will freshen with rain arriving into the southwest of Munster into the afternoon and evening. Feeling cool, with highs of 7 to 9 degrees Celsius.

National Outlook

OUTLOOK: Generally unsettled with spells of wet and windy weather, in particular affecting the west and southwest.

TOMORROW NIGHT: Breezy with outbreaks of rain, turning heavy and persistent across Connacht and Munster, with the risk of spot flooding here. Lowest temperatures of 3 to 6 degrees Celsius, in a fresh and gusty southeast wind.

THURSDAY: A wet and breezy start across the midlands, west and south: surface water too, after heavy overnight rain. Drier across much of Ulster and east Leinster though with sunny spells. Whilst the southeast winds and rain will ease off in the west and southeast, it will remain dull, damp and rather drizzly in these areas for much of the day thereafter. Cool, with highs of 7 to 9 degrees Celsius. Broken cloud and largely dry weather will follow overnight, but with frost and fog, and turning cold with overnight lows of 0 to 5 degrees Celsius.

FRIDAY: A cold and bright start with frost clearing. Dry for daylight hours across many areas, however cloud will tend to build and the winds will slowly freshen. Later in the afternoon rain will move into the west and southwest, and will move up into other areas later in the evening. The rain may even turn wintry locally. Feeling raw, with highs of only 4 to 8 degrees Celsius, in a freshening southeast wind, windy along southern coasts. Further wet and windy spells overnight, with locally high accumulations possible.

THIS WEEKEND: Current indication suggest it will remain unsettled. Rather wet and windy for the early part of Saturday. However it should become drier, calmer and somewhat brighter after that. Largely dry on Sunday with some sunshine, but it will be very cold (frosty to begin), with the risk of rain moving into the very east of Leinster.
