          Short Range Ensemble Forecast System:
          Effective December 4, 2012

On December 4, 2012, beginning with the 1500 Coordinated
Universal Time (UTC) cycle, the National Centers for
Environmental Prediction (NCEP) will implement a fix to the Short
Range Ensemble Forecast System (SREF). The fix will address:

-Incorrect calculations of visibility fields for the following
 11 members: 4 NMMB members (n2, p2, n3, p3) and 7 ARW members
 (ctl, n1, p1, n2, p2, n3, p3).

-Incorrect calculations of ceiling fields for the following
 4 NMMB members - n2, p2, n3, p3.

This fix will not affect format or content included in any SREF
output products, and has no impact on the AWIPS products or
ensemble products: mean, spread and probability.

The Environmental Modeling Center (EMC) Mesoscale Modeling Branch
(MMB) has a publicly available Web site with more information
concerning the SREF modeling system as well as other NCEP
regional modeling systems:
