Extended Forecast Historical Archive

The Extended Forecast Trace uses historical temperature and precipitation information
combined with current hydrologic model states, reservoir regulation, and short-term
meteorological forecasts to produce a single deterministic hydrologic trace.

Forecasts are for a period of 1 day out to 45 or 120 days, depending on time of the
hydrologic season.

Forecasts are present in two forms, formatted text and comma delimitated.
