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.
Whoah! How clever is this? The Metcheck Thunderstorm Tracker Satellite allows you to see the develo...

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
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.
The stratosphere is about 35,000ft above your head right now. So why would that matter with regards to the weather? Well, the vortex over the poles is a major factor with regards to weather patterns around the world.
You've probably heard of Sudden Stratospheric Warming? Well this is the page you can use to see whether the polar vortex is intact (means a mobile weather pattern) or whether a pattern change is about to occur.
The images are updated at 6.25am, 12.25pm, 6.25pm and 12.25am (BST) and take approx 35 mins to complete.
