This is the full meso-eta directory for that case.

Looks as if the May 04 03H run is all that is currently available.

All GRIB files available conform to the following
naming convention. 



{##} is the model number:
                39 = NGM
                77 = AVN
                81 = AVN SSI (initialization)
                78 = MRF
                85 = Meso-Eta (40km)
                86 = RUC/MAPS 
                89 = Eta (run at 40km, output grid at 80km)

{YYMMDDHH} is the year, month, day, and model cycle hour

{T} is the grid type:
                 H = Family of Services
               Y/Z = AWIPS grids 

{G} is the grid number:
                 A = 201 N.Hemisphere
                 H = 213 National CONUS Double Resolution
                 I = 202 National CONUS
                 J = 203 National AK
                 N = 207 National AK
                 Q = 211 Regional CONUS
                 R = 212 Regional CONUS Double Resolution
                 U = 215 Regional CONUS Quadruple Resolution
                 X = Experimental

{F} is the forecast hour:
                 A = 00 (initialization)
                 B = 06
                 C = 12
                 ...      FOR AWIPS GRIDS ONLY, if grid type is Z
                 A = 02
                 B = 03
                 C = 04
                 D = 08

All these numbers & letters come from the GRIB Edition 1 document written
by John Stackpole, and based on the WMO GRIB standard.

Let me know if the 15Z is critical to your research and I might be able to
locate these later or earlier model runs. I assume you were looking for
the 15Z on 3May...

Please let me know if I can be of further assistance.

Thanks for using the COMET Case Study Library,
