Consensus for a northern New England event.

Northern annular modes still well below zero providing well-chilled air masses for dendrite production.  Not the typical NE CONUS snow storm morphology where westerlies amplify and long-wave length shortens...evidenced by flat PNA.

Surface LOW forecast to retro-grade and stall in the Gulf of Maine during next 24 hours...which will likely create a tight baroclinic zone and strong forcing from coastal frontogenesis.

Verification period ends 11:59 PM EST SUN 03-JAN-10.
