Regional-scale modeling is being done in various places.  For example, 
see the work of Lloyd Treinish and his group at IBM -- their "Deep 
Thunder" project predicts local weather using mesoscale high resolution 
(1 km) simulations, which get initialized and updated based on synoptic 
scale (40 km resolution) data from the National Weather Service.

Of course, IBM uses their own hardware (RS/6000) for this...


P.S. Weather model initialization from diverse sources of collected data 
is an interesting problem.  See the Data Assimilation Office at NASA 
Goddard ( for more detail.
