Subject:  Amended:  Addition of mean total sky cover

          to 1200 UTC extended-range GFS MOS text and

          BUFR messages, effective November 5, 2013.

 

Amended to change the implementation date from October

15, 2013 to November 5, 2013

 

On Tuesday November 5, 2013, beginning with the 1200 Coordinated

Universal Time (UTC) model run, the NWS Meteorological

Development Laboratory (MDL) will update the 0000 UTC mean total

sky cover and add mean total sky cover to the 1200 UTC extended-

range Global Forecast System (GFS)-based Model Output Statistics

(MOS) text (MEX) messages.  At present, mean total sky cover is

available in the extended-range message only for the 0000 UTC

cycle.

 

This change will slightly alter the format of the 1200 UTC MEX

message because a line for total sky cover will be added to the

existing bulletin.  After the change, the format of the 1200 UTC

MEX message will be identical to that of the 0000 UTC message.

The communication identifiers for all products affected by this

change are listed in Tables 1 and 2 below.
