Probably weigh 75% EURO. The sleet is a good thing as it takes longer to melt. The METS always say CAD is under modeled. Probably a 1 to 4 inch sleet snow combo for coasties.
NWS just issued WS Watches all the way down to portions of Long Island!
3 to 6 for LI and Coastal CT. I guess they are leaning a little higher than some models
GFS now has the backlash as well. Would early FEB storm of 2015 be a ok analog. Had front end then ice then backlash. Boston had 16. Coastal CT 10.5 not sure about the City
