I measured 24” in Hoboken earlier trying to avoid any areas of drift, so I believe it. Theres been a nearly stationary band over the area for many hours..hopefully it was also over CPK!
Both NWS offices have detailed explanations on their discussion pages for the forecasts and the support/ factors that went into their totals. Not saying it will necessarily verify, but it's not like there's no support.
Same in Hoboken, moderately snowing for a few hours but little accumulation as it's been hovering around 34, although dropped to 33.6 now. I was expecting rain at first and a later onset.
15 and sleet in Hoboken. Measured 10" in the best spot I could find, but definitely some much deeper drifts. Sleet seems mixed with snow, but lots of sleet right now.
