Met Éireann's forecasting charts show snow in the weather for St Patrick's weekend just days after Storm Gareth hits Ireland.
The charts show a lot of rain and wind leading up to St Patrick's Day while another plunge in temperatures is set to be accompanied by a day of heavy rain on Saturday.
"There will be some heavy bursts with a risk of hail. Some of the rain possibly turning to sleet, with snow on hills and mountains. Elsewhere it will be drier with just a few showers, although some of hail," it says.
The forecaster says it will be cold with highest temperatures of 3 to 5 Celsius. It says Saturday night will become dry in most areas, but a few showers will persist in Atlantic coastal counties and a few will be wintry. Cold with lowest temperatures of -1 to +3 Celsius with frost and icy stretches.

Breezy to begin tomorrow Friday. Many places will have a largely dry day, however scattered showers will affect the north and northwest, and patchy rain, drizzle and mist will persist in west Munster. The best of the brighter intervals will be in the north and east, with mostly cloudy conditions prevailing elsewhere. Top temperatures 7 to 11 degrees, with the gusty westerly winds moderating through the day. Rain will become more widespread again on Friday evening.
Headline: Cold and unsettled over the weekend, with a risk of wintry precipitation, especially in the north and northwest and also some frost. Early indications suggest that mild, more settled weather is likely to develop next week.
Friday night: Outbreaks of rain will become widespread, with some heavy falls and a risk of spot flooding, especially in parts of Munster. Rain will turn to sleet and snow in parts of north Connacht, Ulster and north Leinster, with temperatures there falling close to freezing, but air temperatures elsewhere will range 2 to 6 degrees, highest in the south and southwest. Winds mostly light to moderate overland, variable in direction, but strong southwest winds will develop along Munster and south Leinster coasts.
Saturday: Rain in the early morning, heavy in places, with falls of sleet and snow in some northern and northwestern areas, but brightening up gradually from the northwest during the morning and early afternoon, with scattered showers following. However, it will turn much colder everywhere and some of the showers will turn wintry, especially in the north and west, but in other parts also, with hail, sleet and a risk of snow. There is also a risk of thunder. Maximum afternoon temperatures 2 to 5 degrees in the north and northwest, 6 to 9 Celsius elsewhere. Winds mostly moderate northwesterly. Saturday night will be dry in many areas, but there will be further wintry showers, mainly in west Ulster, Connacht and west Munster. Very cold, with widespread frost and a risk of icy stretches.

Further outlook, Monday to Friday: Early indications suggest that it will be mainly dry and settled, but there will be a little patchy light rain or drizzle at times, mainly along western and northwestern coasts.
