<b>Abstract</b>: Numerical weather prediction (NWP) has grown
considerably from its humble beginnings decades ago. Current
state-of-the-art NWP models routinely produce skillful global
forecasts at high resolution thanks to advances in computational
fluid dynamics, understanding of physical meteorological
processes, and availability of supercomputing resources. These
advances have led many prediction centers worldwide to stretch
the boundaries of their systems and begin exercising these
models in spatial and temporal domains outside those of
traditional NWP. One such system is the Navy Global
Environmental Model (NAVGEM), which delivers operational
tropospheric weather forecasts for the U.S. Navy. Recent
development has provided a configuration of NAVGEM that
leverages new scientific and computing capabilities to deliver
long-range seasonal forecasts up to 100 km in altitude. A
prototype research configuration is also in development that
extends this capability even further to deliver space weather
forecasts of the thermosphere up to 500 km in altitude. This
presentation will review uncovered challenges in long-range and
space weather prediction and describe novel strategies in
evolving NAVGEM from a global NWP model into a whole atmosphere
prediction system.</div>
