IBM has launched a new weather service called Deep Thunder that can predict the rain, the wind, and temperature conditions down to a one-kilometer resolution. In time, IBM researchers say they should even be able to nail the resolution down to individual streets.

Deep Thunder increases the resolution by using IBM’s pSeries Cluster 1600 computers — a mini-supercomputer — to include additional information about the local area that can affect weather conditions, such as the topographic layout of the metropolitan area and coastal information, such as the city’s exposure.
