Surface Pressure Charts
showing pressure and weather fronts are provided up to five days ahead for Europe and the North East Atlantic.
These charts show the surface pressure pattern using isobars (lines of equal pressure) and indicate areas of high (H) and low pressure (L) along with their central pressure value. Isobars are represented by solid lines. High pressure is usually associated with settled weather while low pressure is normally associated with unsettled weather. Fronts are also displayed. An analysis chart, which shows the observed state of the weather, is issued along with forecast charts up to five days ahead. These are updated every 12 hours around 0730 UTC and 1930 UTC, with the exception of charts for days four and five which are only issued once per day at 1930 UTC. The reason that these two charts are only issued once a day is because that far ahead the forecast surface pressure pattern will change more significantly, due to uncertainty at this longer time period, and there is limited value in updating it every 12 hours.

WINDY Map and Weather Forecast
A UNIQUE WEATHER FORECAST VISUALISATION
While most weather forecasting apps rely only on free global models, Windy has gone a few steps further and invested heavily in the most accurate models available, always at the highest possible resolution, to ensure accurate weather forecasts.
WEATHER RADAR & SATELLITE IMAGERY
A weather radar is the most requested tool for weather forecasting. To provide the most accurate radar imagery, we constantly expand our resources so that rain, snow, and storms don’t catch you by surprise. Trusted sources include NOAA, Met Office, AROME, DWD, JMA, ACCESS, and others.
Some Aviation tools like:
- Wind forecast (current speed, gusts, accumulation, models comparison, data from weather stations)
- Temperature, humidity, pressure, dew point, freezing altitude
- Rain, thunder, storms, precipitation type, CAPE-index
- Weather radar and Satellite images (blue, infrared, visible)
- Clouds, clouds tops, clouds base and visibility (LIFR, IFR, MVFR, VFR), fog.

METAR TAF
The Graphical Forecasts for Aviation (GFA) include gridded displays of various weather parameters as well as National Weather Service (NWS) textual weather observations, forecasts and warnings. Icing, turbulence, and wind gridded data are three-dimensional. The weather observations and forecasted data are listed under the Weather dropdown menu within the page header. Forecaster produced warnings and advisories can be found under the Products dropdown menu, along with TAF forecasts, Prog Charts, and Forecast Discussions.
