Becoming milder as the night goes on though, as winds back southerly and increase fresh to strong and gusty, with gales developing along some western, northern and eastern coasts by morning.
Wednesday: Wet and blustery to begin on Wednesday with widespread outbreaks of rain and drizzle in fresh to strong southerly winds. A clearance will develop in the west by the afternoon, with drier, clearer and calmer conditions gradually spreading eastwards through the rest of the day. Afternoon highs of 9 to 13 degrees with winds veering light to moderate southwest with the clearance of the cloud and rain.
Thursday: Uncertainty in the details for Thursday at present, but current indications suggest another spell of rain may move up from the south and affect eastern and southern parts of the country to start the day. The rain looks set to clear eastwards, allowing scattered showers to spread from the Atlantic, some them heavy with hail and isolated thunderstorms possible. Highest temperatures of 7 to 11 degrees in moderate southwesterly winds.
Friday and Next Weekend: Confidence in the forecast is a little lower than usual for the lead time. A zonal Atlantic regime looks set to persist at first, but there are tentative signs that more settled conditions may develop by the end of the weekend.
