  1. I melted down my 3.0" of snowfall from overnight and once again got a perfect 10:1 ratio with 0.30" of liquid.  The weird thing is that both nights were 10:1 snow but last night's was way wetter than Thursday night's.  I don't get that.
    I'm sure this will change but this morning's 12Z HRRR (which ends at 0Z tomorrow evening) starts the storm as rain early tomorrow afternoon and for portions of the LSV keeps it rain until sunset.  I think it has to do with precip rates in which it doesn't show the rain changing to snow until rates ramp up later in the afternoon.

    I thought the dendrites were bigger in the 2nd event and they stacked higher.

  2. And that's what I hate. There is more to weather than just snow. Try to start a discussion about thunderstorms and tropical systems, and it's mostly crickets in here...

    I do like tracking severe storms and hurricanes.

    Hurricanes can do so much damage and cause pain and suffering it is tough to “root” for a big storm.

    Severe weather is hit or miss, so not as much tracking. And again “rooting” for severe weather is tough because people can die.

  3. Thanks, I guess I should have said 5-7" not 4-6" bit I saw the 3" marker over in Lancaster county so was smoothing it a bit.  Either way it is Certainly a step down from the possibility of 6-12" just yesterday.   Big NAM running coming up :-).

    Storm has lost some of that northern stream energy so although it has reduced mixing issues it has also reduced amount of forcing.

    Anymore deamplification and it’s another 2” to 4” event with even more marginal cold air.

  4. Only problem with that map is it includes at least half of last night's overnight snow.  I'd take at least 1 to 2" off those totals to come up with the forecast for tomorrow.
    I ended up with a surprise of 3.0" of snow on the board this morning.  This snow was wetter as it stuck to the trees significantly more and the woods are really looking very white this morning.  It was really coming down as I went to bed around 1:30...as heavily as the night before.  Pleasantly surprised for sure.  That's 6.8" for the 2 days.  Now we wait to see what tomorrow brings.

    Here is the correction factor map. Subtract that from previous posted map.

  5. If flying SW I would be a bit worried.  Both because of the snow and their penchant to ground flights early and often.  

    Bingo.

    SW grounds flights quickly, and that is what I’m flying....from BWI.

    During that 2017 March Storm, BWI had maybe and inch or two of slop and flights were cancelled.

    MDT had 20” of snow and I booked a flight same day from there on a different airline, and the flight left on time.
