Cold and blustery this evening with bright spells and showers, some with hail.Tonight
Cold and windy tonight with clear spells and showers. The showers will be most frequent across Ulster and Connacht with some wintry falls and with the risk of hail and thunder near Atlantic coasts. Minimum temperatures of between zero and +3 degrees with a frost forming in sheltered areas. Fresh to strong and gusty north to northwest winds.
Tuesday will be a very cold day for late April with a mixture of sunshine and showers. The showers will initially affect northern and western coastal fringes but will become widespread during the afternoon, some of the showers will be wintry with the risk of hail and thunder. Top temperatures of just 6 to 10 degrees in a fresh and gusty northerly wind.
Headline: A brief cold, showery spell of weather for the first half of this week. Less cold after midweek, but changeable and unsettled.
Tuesday night: Cold under clear spells, with showers retreating to the coastal fringes. Wintry falls possible in any showers that drift inland, with the main risk of this about Ulster. Northerly winds will fall back light, leading to a fairly widespread frost. Minimum temperatures of -1 to +3 degrees.
Wednesday: Still rather chilly, but a bright day with sunny spells and showers. The showers won’t be as heavy as on Tuesday and the risk of hail and thunder will have diminished. Top temperatures of 7 to 10 degrees in light to moderate northerly breezes.
Wednesday night: Not quite as cold on Wednesday night owing to increased cloud cover, and some patchy rain, chiefly across northern and eastern parts. Still a few clear spells, though, allowing temperatures to fall to between 2 to 6 degrees, in slack northwest winds, leading to a slight grass frost in places.
Thursday: Mainly cloudy on Thursday with patchy light rain or drizzle in places. Top temperatures of 9 to 12 degrees in light to moderate northwesterly breezes.
Friday and the weekend: Still a degree of uncertainty with regard to the details and timings for the end of this week. Frontal systems in the Atlantic look to make slow progress eastwards, but they will eventually bring unsettled – wet and windy - conditions to all parts during the weekend. Early indications suggest Friday could hold dry with just increasing cloud amounts, with the wettest and windiest conditions expected later on Saturday and through Sunday.
