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.

Today
Treacherous conditions in places for the rest of today with lingering frost and ice. Sunny spells and scattered wintry showers of sleet and snow will occur, mainly across northern and western counties with local accumulations and perhaps the odd rumble of thunder. Rain will affect southwest counties for a time also, turning to sleet or snow over higher ground here. As well as this, a few snow flurries will feed into north Leinster later this evening, bringing the potential for a light dusting. Very cold with highest temperatures of only 1 to 5 degrees in light to moderate westerly winds.
Tonight
Very cold overnight with a widespread sharp to severe frost and icy stretches. Scattered wintry showers will continue, mainly in the North and West, with local snow accumulations and impaired visibility. A few well scattered snow flurries will also feed into the other areas too with a light dusting. Patches of fog or freezing fog may form also. Lowest temperatures of -6 to -1 degrees in light to moderate northwesterly winds.
Tomorrow
Monday will be another very cold and treacherous start with frost, ice and fog or freezing fog patches slow to clear. Some lying snow in places too, mainly across north and northwest counties. Dry and sunny day for most areas, with wintry showers mainly confined to north and northwest fringes by late morning. Highest temperatures of only 1 to 6 degrees in light to moderate northwest to west winds.
