GFS model charts

Metcheck GFS Model Charts


About this page


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.

Help & Info

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

Ensembles ▼

Ensembles are clever things. If you ask a weather forecaster whether it will rain next week, they will probably say "Well, it may do. Or it may not...". That really isn't very helpful, so this is where ensembles come into play.

Every 6 hours, the GFS weather model is run not once, but 20 times and this gives us a fantastic tool to see how many of the model runs agree with each other. Click on the tools below for more information on ensemble forecasting.

Model Time Plots ▼

No, it's not something out of Dr Who! The GFS Time Plotter allows you to scan the entire dataset of the latest GFS model run and find out the maximum, minimum and average values of all the weather variables.

This feature is especially handy when it comes to perhaps totaling up rain values, or finding the highest wind speeds.... but it doesn't do time travel, we've tried.

Jet Stream ▼

You probably hear a lot about the Jet Stream in the news. It's either too far North or too far South. The jet stream is identified as winds at 300mb (during Winter) and 200mb (during Summer). It is these winds which are responsible for driving and developing weather systems across the Atlantic.

The images are updated twice a day at 6.10am and 6.10pm (BST) and take approx 20 mins to complete.
