The Met Office in Exeter is to get a new super computer - costing £97 million.
It'll be able to perform 16,000 trillion calculations a second and will weigh the equivalent of 11 double decker buses.
It will be able to provide very high detail weather information for precise geographical areas and help predict events such as flooding and heavy snowfall more effectively.
It's being welcomed by the Chief Secretary to the Treasury, Danny Alexander.
We've a fascinating insight now into the role the Met Office played in the lead up to the D-Day landings, which took place 70 years ago this week.
