The US is way behind on weather modelling, in part due to lack of computing power available to do the grids at sufficiently small cells compared to Europe and other parts of the world. That means less accurate predictions and less advance notice of impending disasters, which means more risk of loss of life and impact on infrastructure and the economy (and vice versa, inaccuracy can lead to more caution than is necessary, which has economic impact too). The US has to lean on Europe etc. for predictions.

Talks about the fact that IBM / Weather.com actually uses a more accurate system than the NWS uses, because the NWS is still stuck on GFS (been several years now since congress passed an act to force NOAA to update away from it, and unfortunately it takes time)
