7 March 2011 - Banded Precipitation Diagnostics

SUMMARY: Laterally quasi-stationary snowband (translation along long-axis of banded precipitation structures across NW VT and northern NY). Aspects of case generally consistent with other events, although Qs in this case may not be small.

Occurred during a positive phase of the NAO (5 Mar 2011 1.356;6 Mar 2011 0.969;7 Mar 2011 0.755;8 Mar 2011)
