Isobars: Isobars, lines of equal atmospheric pressure, are drawn every 4hPa (hectopascals or millibars). Areas of High and Low pressure are indicated.

Rainfall: Rainfall accumulated over 6 hours. The deeper the shade of blue, the heavier the rainfall. Some regions of very light rainfall may not be indicated.

Cloud: Computer generated cloud using fractals shows the extent of predicted cloud amounts.

Temperature: Areas of warmer and cooler air are represented by red and blue shades respectively.

These charts come from a computer model of the weather called Hirlam. These are the same charts used as guidance by Met Éireann forecasters. The forecasters, however, will also take into account the latest satellite and radar imagery, and the latest weather station reports, in producing the forecast. These charts, therefore, may not always be consistent with the official forecasts as shown on the "Detailed Forecast" and "Regional Forecast" pages.
