March is normally the highest sea ice extent month in the Arctic Ocean. Here is Mar 2015 compared to Marches past (NSIDC). Yes, its a record low for the satellite era.

You know all that snow that fell in the East this winter? Here's where it all came from.

NSIDC scientist Andrew Slater maintains regular updates of western U.S. mountain snowpack conditions using data from the SNOTEL (snowpack telemetry) system – a network of automated sensors that measure snow water equivalent. The automated SNOTEL sites are complemented by snowcourses, where snow water equivalent is measured manually on a periodic basis.

Typically, the snowpack peaks around April 1. As seen in Figure 5, the April 1 snowpack over most of the western United States is far below average. At many sites, snow water equivalent is at historic lows for this time of year.
