Effective with the 1200 UTC forecast cycle on June 11, 2002, MDL will begin disseminating new Eta MOS(MET) guidance. Guidance is available for 1258 sites in the continental US. They are listed at www.nws.noaa.gov/mdl/synop/stadrg.htm. The Eta MOS guidance will be produced at the 0000 and 1200 UTC model cycles. At this time, forecasts are available for maximum/minimum temperature, surface temperature, dewpoint, wind speed and direction, PoP and QPF, and total sky cover. In the coming months, we will be adding thunderstorm and severe weather forecasts, and precipitation type guidance to the messages. In addition to the alphanumeric text messages, we have some GEMPAK images of the forecasts on our website.

The alphanumeric messages will be available on the AWIPS/NOAAPORT datastream with the following headers:

AWIPS ID	WMO HEADER
----------------------------
METNE1		FOUS44 KWNO
METSE1		FOUS45 KWNO
METNC1		FOUS46 KWNO
METSC1		FOUS47 KWNO
METRM1		FOUS48 KWNO
METWC1		FOUS49 KWNO

On or around June 25th, the alphanumeric text messages and GRIB files will be available for anonymous ftp on the NWS ftp server, tgftp.nws.noaa.gov. We will send more details about the location of these files as the date approaches.

In the future, we will produce files containing the Eta MOS forecasts in BUFR format.

Technical Procedures Bulletin 486 describes the format for the Eta MOS MET message.
