High Resolution NWP Reflectivity Comparison
Select a WRF based high resolution simulation below and then hover over the forecast hour to
display the corresponding low level reflectivity forecast. The product is the 1km Reflectivity
unless noted as (cr) for composite or (sfc) for surface. Click on the check box to animate.
Be sure to pay attention to the model run time and forecast valid times.

A reference chart that contains information
on the various high resolution NWP sources including model configuration, initial/boundary conditions, and parameterization
is available here.
Comments or if you find this service useful,
please let us know !
NCEP model status information is available via the NCEP Production Suite Status Page.
Status information on the HiResWindow runs is available via the HiResWindow log.
Information on which tropical cyclones are being simulated by the HWRF and could be precluding the HiResWindow runs is available on the
Tropical Guidance Page

Recent research has shown that convection allowing high resolution NWP reflectivity forecasts can be
useful in the forecast process when used appropriately. The journal articles below provide some additional
