Subject:  Soliciting comments on the experimental NWS Hydrologic
          Short-Term Meteorological Model-Based Ensemble
          Forecasting System from January 1, 2011 to
          June 30, 2011

From January 1, 2011, to June 30, 2011, the NWS will be seeking
comments from users on a new experimental NWS hydrologic short-
term(0-7 days) meteorological model-based ensemble forecasting
system (MMEFS). During this experimental period, MMEFS
information will be generated by the following River Forecast
Centers (RFC): Northeast RFC, Middle Atlantic RFC, Ohio RFC, and
the Southeast RFC.

The MMEFS uses the temperature and precipitation output from the
National Centers for Environmental Prediction (NCEP) Global
Ensemble Forecast System, Short Range Ensemble Forecasts, and
the North American Ensemble Forecast System.  These ensemble
member outputs and the current hydrologic model are run through
the RFC Ensemble Streamflow Prediction System to generate a
number of possible river forecast outcomes. The outcomes are
turned into short-term probabilistic forecasts. MMEFS
supplements the operational river forecasts available online at:


The MMEFS web pages are available online at:
