Snow Storm #8: Preview Redux

Today/s 12z NWP solutions in strong agreement with their depiction of cyclogenesis along the SE CONUS coast on SUN.

The image loops today/s 72-hour forecasts from the 12z runs of the ECMWF... UKMET...GFS...and GEM.

The upper LOW isn/t all that cold; however...strong HIGH pressure parked over eastern Canada will be needed to maintain low-level cold air. Synoptics also suggest a threat for freezing rain...especially coastal stations in New England and the mid-Atlantic/s inland stations.

NAM time-height x-sections suggest ~9 stations could be in play...more than enough to get #8 finally off the ground. After a healthy pace during the first two months of winter...FEB has turned out to be a big disappointment. Not a single contest-worthy storm. Snowfall climatology favors FEB as prime-time for most mid-Atlantic stations.

Should this scenario still seem likley tomorrow...a call for forecasts will come Friday evening with an entry deadline several hours earlier than usual Saturday evening so as to include snowfall in Pennsylvania.
