Knowledge of subsurface soil moisture contributions at the start of seasonal or subseasonal forecasts can potentially increase the skill of hydrometeorological forecast through the impact of soil moisture on the surface energy budget and associated evolution of meteorological quantities. This presentation introduces the contribution of soil moisture initializations to subseasonal hydrological forecast skills at one of the most severe drought events in 20th century (The drought of 1988 in US). Soil moisture initializations are based on offline land surface model simulations with realistic atmospheric forcing data which is used in the Global Soil Wetness Project-2. Results, which focus here, show significant contributions to surface temperature forecast skill out 31-45 days across the North America.
