NBM Snow Level Forecast

NBM Snow Level Forecast

These graphics show the 8-day snow level forecast from the National Blend of Models (NBM).  These are produced and posted to the web once per day at 15Z (7am AKDT/6am AKST) from the most current run of the NBM.

The NBM Snow Level is determined from the wet-bulb zero level, which is the lowest level in a sounding at which the wet-bulb temperature is 0°C.  The units are feet above mean sea level.  If a location's elevation is higher than the given snow level, then the user should interpret that the snow level is at the surface.
