Tomorrow

Highs of 8 to 12 degrees with strong and gusty southwesterly winds. The rain will start to clear the northwest towards the evening.

Outlook

As the last of the rain clears the southeast, it'll become dry and clear on Tuesday night, and it will turn colder too as a moderate west to northwest wind becomes established over the country. Temperatures will fall to between plus 1 and plus 3 degrees. Wednesday, Christmas Eve, will be mainly dry. Some sunshine will develop for most places but Atlantic showers will affect coasts, dying out before making any progress inland. It will be a noticeably colder day though with a moderate westerly wind, decreasing light later. Temperatures in the afternoon will be between about 5 and 8 degrees generally, but along the south coast it'll be a milder 10 or 11 degrees, and it will become very cold and frosty overnight with temperatures down below freezing for most places. Thursday, Christmas Day, will start out cold and frosty. It will be a dry day with light winds and with some sunshine too. Temperatures will be low, between about 4 and 7 degrees, coldest in the east. Winds will be light westerly or variable in direction. Under clear skies on the night of Christmas temperatures will fall to between minus 2 and minus 4 degrees as winds fall off and skies clear.Beyond St Stephen's day the outlook becomes much more uncertain. At the moment it looks like St Stephen's day will be dry to start with rain developing from the west later in freshening southerly winds. It looks likely to become milder again too but there is a large degree of uncertainty in the atmosphere beyond the short range.
