  1. I don't think it's that easy though.. Nam had a general 2-4" across a large area that already has 4-8" down there..
  2. Everything was earlier (start and sleet), I'm more looking at totals when it changes to sleet, still not sure what to believe yet. I really want to see Baltimore and Philly totals before changeover than compare to EURO/NAM/HRRR etc.
  3. 4" unofficial measurement in the Greenwich/Rye Brook/ Tarrytown area, might be a local jack there north of the Merritt as they had a 3" head start on areas just NE as we saturated..
  4. Visibility dropped quick steady snow 7.7 degrees .. Took 50 minutes from first flakes to steady snow..
  5. I think it's more of a function of earlier start time as the amount of sleet is still the same?
  6. Finally steady light snow with a coating.. Nice band getting ready to move in, should be snowing heavily by 8am.. which is about 3 hours earlier than I thought last night ..
  7. There's def a brick wall of dry air past SW CT, having a hard time saturating here , still just random flakes for 30 minutes now , where as the NYC metro went straight to heavy snow instantly. Dew point depressions slowly dropping
  8. No doubt, my forecast for first inch was between 9-10am in Tarrytown.. So way ahead of schedule with 1.5" at 7am.
  9. Greenwich probably has close to an inch I'd assume based on radar and duration, waiting for an ob from a snow removal client in Tarrytown about 5 miles west of greenwich .. EDIT he says about 1.5" "very fluffy snow"
  10. Still Heavy snow and low vis live cam in DC right now.. That 700mb warm layer has met some resistance already
  11. What is the board clearing rules for a storm of this duration? How many hours in? Do I do it when I change to sleet?
  12. @ORH_wxman how big is the scope of the 10"+ compared to some of the other big ones? An area from Texas to Maine 300-600 miles wide seems insanse.
  13. ya hard to tell exactly where it is based on obs and CC, it should be a few hours ahead as the accumulating snow is about 2-3 hours ahead up here..
