This high-resolution weather forecasting model is being produced by the NWS in Pleasant Hill, MO. The model domain is centered west of Kansas City, and covers an approximate area from Valentine, NE (northwest corner) to Blytheville, AR (southeast corner). A smaller domain allows the model to be run at a 4 km grid point spacing, which means features as small as ~10 miles in width can be resolved in the model output. These data, in conjunction with model data run at the National Centers for Environmental Prediction (NOAA NCEP), are being used by the NWS in Pleasant Hill to aid in short term forecasting.

The EAX 4km WRF-ARW is run 4 times daily at 10:30 AM, 4:30 PM, 10:30 PM, and 4:30 AM CDT, and the output is typically available in about 6 hours. Forecast length is 24 hours, and forecast products are available for every hour in this 24-hour period. The 13 km RAP is used to initialize this model, and the 12 km NAM is used to represent conditions outside the model domain. A few other technical specifications of the model are:

  • Core: WRF-ARW
  • Convective Scheme: Off (explicit convection)
  • PBL Scheme: ACM2
  • Microphysics: WDM6

This is a new product, and therefore has not gone through any thorough evaluation or verification. As a result, please use only as a supplement to forecasts issued by the National Weather Service and other model data.
