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.
