NOAA PSL GEFS Reforecast Version 2 is another option for medium range forecasts.

This Reforecast V2 dataset consists of an 11-member ensemble of forecasts, produced every day from 00 UTC initial conditions from Dec 1984 to present. The horizontal resolution of GEFS is T254 (about 50 km) out to 8 days, and T190 (about 70 km) from 8-16 days. Real-time forecasts are ongoing.

This website is also a good for seeing what products are available.

Dietze et al. use NOAA GEFS since it has a decent number of ensembles. Thomas et al also use GEFS for driving GLM lake temp forecasts - see here. Check out rNOMADS R package for downloading data. Katie Zarada says

I use PEcAn.data.atmosphere::download.NOAA_GEFS_downscale() to get GEFS downscaled to hourly data or you can use PEcAn.data.atmosphere::download.NOAA_GEFS() for 6 hourly

PEcAn functions from here.
