These are the latest NCEP GFS model weather charts at Metcheck.
The maps below show a variety of weather variables and are in 6 hour intervals out to 192 hours then every 12 hours out to 384 hours ahead. The images begin updating at 4.30am, 10.30am, 4.30pm and 10.30pm (BST) and take approx 90 mins to complete.

Sea Level Pressure - Plotted using isobars displaying the pressure levels in contours 3hr Rainfall - Displays sea level pressure and the accumulated 3hr rainfall amounts 2m Temperature - The forecast temperature in centigrade at 2m above ground Freezing level - This is also known as the zero degree isotherm and shows the height at which all air above is freezing or below Rain/Snow - This shows you whether precipitation will fall as sleet or.... snow. 850mb Temperature - This is the temperature of the air at the 850mb pressure level. This is the height at which day and nighttime heating have no effect on the atmosphere CAPE - This is the amount of convective potential of the atmosphere for the creation of thunderstorms Cloud Cover/Thickness - This displays the cloud cover, rainfall and thickness of the air showing how precipitation is likely to fall. 10m Wind Speed/Gust - This is the forecast wind direction and gust wind speed at 10m above the ground
Whilst the GFS is a great model for global forecasts, for absolute local detail you need a much higher resolution model. Instead of interpolating the GFS model which many other weather sites do, we run the Harmonie weather model for the UK.
This super high resolution model forecasts the weather for the next 48 hours in 3 hour intervals at a resolution of 2.5km! The images are updated at 8.15am and 10.45pm (BST) and take approx 5 mins to complete.
