Latest Rainfall Radar showing live precipitation and the last 90 minutes precipitation over Ireland, updated every 5 minutes. Precipitation can be rain, hail or snow. Accumulations can refer to rainfall only.
Lightning strikes, when they occur, are displayed as a cross. Initially, they are red but change to orange and then yellow after a period, then disappear © Met Office ATDNet.
Ground Clutter may appear (South Co. Dublin), bright bands and spokes may also be present in images. They are artefacts (false echoes) of rainfall radar systems and should be ignored. Further information on Radar here
Met Éireann forecasters manually produce the weather icons for midday and midnight to reflect the predicted major weather type for these times.
The rainfall forecast is direct model output from Numerical Weather Prediction models but is a guideline only. Rain refers to precipitation, which can be rain, sleet or snow. It forecasts how much rain will fall (in mm) hourly during the previous hour (accumulations), then in 3 hourly and finally 6 hourly accumulations up to 7 days. This service is based on data and products of the HARMONIE-AROME and the European Centre for Medium-range Weather Forecasts (ECMWF) models.
The wind is direct model output from Numerical Weather Prediction models but is a guideline only. It forecasts the strength of the wind (in knots and km/h) at 10m for the top of each hour, in hourly, then 3 hourly and finally 6 hourly intervals up to 7 days. The wind arrow tip points in the direction the wind is blowing and the tail length indicates wind strength. However, in the text forecast below, it is described as where it is blowing from. This service is based on data and products of the HARMONIE-AROME and the European Centre for Medium-range Weather Forecasts (ECMWF) models.
The temperature is direct model output from Numerical Weather Prediction models but is a guideline only. It forecasts air temperature on land and over sea in °C for the top of each hour, 3 hourly and finally 6 hourly intervals up to 7 days. Minus zero (-0) indicates values between 0 to -0.5°C. This service is based on data and products of the HARMONIE-AROME and the European Centre for Medium-range Weather Forecasts (ECMWF) models.
The Mean Sea Level Pressure (MSLP) is direct model output from Numerical Weather Prediction models but is a guideline only. It forecasts the MSLP in hecto Pascals (hPa) for the top of that hour initially in 3 hourly intervals, then 6 hourly. This service is based on data and products of the HARMONIE-AROME and the European Centre for Medium-range Weather Forecasts (ECMWF) models.
National Forecast
20 November 2024 21:35
Tonight
A very cold and wintry night with outbreaks of sleet, snow and rain spreading from the west. Scattered wintry showers will affect parts of the north and northwest. Some snow accumulations are likely across the country. Lowest temperatures of -4 to 0 degrees in light to moderate easterly or variable winds. Frost and icy stretches will develop too.
Tomorrow
A very cold, wintry and treacherous start to Thursday with a dusting of snow starting out across many areas; frost and ice in places too with some spot flooding across southern fringes starting out. Outbreaks of snow, sleet and rain will clear most areas by mid-morning, and southern counties by midday. While some sunny spells will develop, scattered wintry showers will follow into Atlantic counties. Icy stretches will linger through the day in place with maximum temperatures of just 1 to 4 degrees in light to moderate northwesterly winds, fresher near northern coasts.
