Subject:  Western Region WFO use of Weather Research and

          Forecasting (WRF) Model Output will become Operational

          Effective February 26, 2013

 

Effective February 26, 2013, at 1800 Coordinated Universal Time

(UTC), Weather Forecast Office (WFO) Weather Research and

Forecasting (WRF) model output will become an operational

product in the NWS Western Region. The WRF Model Output has been

available as an operational product at WFO Sacramento (STO), CA,

since 2009 and in experimental status at several other Western

Region WFOs since 2011. The decision to make it an operational

product available for use at all Western Region WFOs is based

upon favorable comments received during the period of public

comment and review.

 

The WRF Model Output is currently available on the following

webpages:

 

Monterey (MTR), CA:   http://www.wrh.noaa.gov/mtr/mtrwrf.php

Phoenix (PSR), AZ:    http://wrh.noaa.gov/psr/wrf

Pocatello (PIH), ID:  http://www.wrh.noaa.gov/pih/wrf/

Sacramento (STO), CA: http://www.wrh.noaa.gov/sto/sacwrf.php

Salt Lake City (SLC), UT:

http://www.wrh.noaa.gov/slc/projects/wrf/wrf.html

San Diego (SGX), CA:  http://www.wrh.noaa.gov/sgx/wrf

 

 

Other WR WFOs may choose to run and display WRF model output in

the future.

 

The WRF is run locally at a WFO. The WRF ARW or WRF NMM

generates hourly to 3-hourly output from 24 to 120 hours,

depending on element. The high resolution model is used for

operational forecasting and research at the local WFO. Model

output graphics are posted on a WFO Webpage. Some of the fields

include: temperature, dew point, relative humidity, wind,

precipitation amount and type and sea level pressure.
