Note: Wednesdays are the preferred snow survey day.  This day allows for the most recent data to supporting River Forecast Center modeling efforts and Weather Forecast Offices flood outlooks.  Tuesdays and Mondays are also acceptable as snow surveys days.  The Eastern Region goal is for ALL SNOW SURVEYS to be TRANSMITTED WITHIN 6 HOURS OF THE OBSERVATION using an RR2 product.  Additionally, the National Operational Hydrologic Remote Sensing Center requires that all snow observations be less than 24 hours old to be useful in snow data assimilations.
