  1. Is there some official repository of leaf-out/bloom dates for various locations in the area? I never really follow it but am curious how "late" we really are.

    April 2nd Snow Wave

    Snow picked up a bit around 8:45-9:00 am, but really backed off in the last 5-10 minutes. Looking like accumulating snow is about over. Final tally for my house as of 9:15 am is 4.0" (about 2" on pavement). Pretty amazing for 4/2. Should be mostly gone by tomorrow, lol.

    Snow has backed off a bit to moderate and the sun is starting to do its dirty work of melting/compacting, I think. We're at 3.5" as of 8:30 am and I would've thought we'd have more in that last 40 minutes - again, think we're seeing compaction (and snow on the busy road in front of us is definitely melting). Still a beautiful snowfall with no wind and the snow cliinging to everything. Still 32F. By the way, 3.5" puts us over 50" for the season at 50.2"!

    Holy crap it's pouring snow here. Went from 2.25" at 7:20 am, when it started snowing heavily, to 3.0" at 7:50 am, which is 1.5" per hour rates. 4" definitely looks in range now, given the look of the radar - only need another 30-40 minutes of snow like this to get there.

    Heaviest snow of the event started around 7:20 am - ripping! Up to 2.25" as of 7:20 am. Radar looks great - thinking we at least get to 3" by 8 am and who knows maybe 4" is in reach for the storm. Roads now covered locally. 32F still. Gorgeous.

    I am not, as I've said a few times - it's all about snowfall rates exceeding melting rates and the snow quickly cools the surface (it takes up the heat from the surface to melt the initial snow), especially before the sun angle is a factor, and once a layer of snow covers the surface, then it's snow falling on 32F snow and it will accumulate easily.

    As of 6:05 am, we have 1/2" of snow on colder surfaces and it's just starting to stick on the driveway and sidewalks; temp is also down to 33F now. Coming down moderately to close to heavily. Very pretty snowfall with little wind - sticking to everything not named asphalt.

    Snow already starting to accumulate on cartops, deck and grass (earlier than I expected). Down to 34F here. Assume it'll take at least an hour on the warmer paved surfaces unless we get into some heavy snowfall (moderate right now). And according to the WSI radar, the rain snow line has collapsed to about 276/195 already (never been that impressed with its ability to distinguish rain from snow, but that's what it says).

    Surprisingly starting off as snow here, after maybe a 10-15 min of light rain. It dropped from 40F to 35F over the last hour. Advisories are mostly unchanged, but the NWS did update the maps and cut some south of 78 and especially 276/195. We'll see soon...
  10. From her paper... Results of the statistical analysis suggest that cool-season NE precipitation tends to be enhanced during positive-to-negative NAO and negative-to-positive PNA transitions, and suppressed during negative-to-positive NAO and positive-to-negative PNA transitions. Of the four types of regime transitions, only the positive-to-negative NAO transition is associated with substantially more frequent major cool-season NE precipitation events compared to climatology. https://journals.ametsoc.org/doi/abs/10.1175/2010MWR3362.1
  11. Just for giggles...point isn't to say this will happen, but to show potential of pattern (most of this for I-95 corridor is on 4/2)...
  12. That's basically what I think should be done, but I get it's more complicated and relies on someone actually being there to make those judgments, whereas simply measuring total snowfall after 24 hours or at the end of the event is simpler. I guess there's no simple answer to this...
  13. Thanks, but I've never been able to figure out how to make a snowfall map from that site and frankly, I shouldn't have to. The NWS ought to simply provide the map in some easy to find location on each CWAs winter page and also on the Eastern Region page.
  14. I find those guidelines to be a bit confusing at times. First off they say that "if required to take observations every 6 hours" (for contract employees) you can clear the board at those times. That, to me, implies it should be ok for Joe Q. Public to do the same (if it's good enough for the NWS/FAA, why not everyone). Second, they talk about measuring the max snowfall at the end of the storm, where possible, prior to melting and compaction Per their example: "Snow begins to fall at 10:00 a.m., accumulates to 4.2 inches by 3:00 p.m. and then stops. Ideally, this is when you should measure the snow. The snow begins melting and settling such that by your observation the next morning you only have 2.6 inches of snow on your snow board. The correct number to report for your 24-hour snowfall is 4.2 inches - the accumulation prior to melting and settling." That makes sense, but there's no allowance for melting/compaction that occur in a snow to rain/sleet to snow scenario, like we had on 3/7, where got about 3.5" of snow, then a bunch of sleet and rain, which compacted the snow to 2" in depth; it then changed back to heavy snow and the final depth was 8.5" (with 6.5" of new snow on top), but IMO 10" of snow accumulated in two parts (3.5" and 6.5"). If the event had ended after 3.5" of snow and just rain fell afterwards, you'd get to count the 3.5", but the fact that the storm didn't end and changed to means you can't count that the 3.5" as part 1. Maybe this is all too picky, but wondering what others think.
  15. Here's the NWS Eastern Region map, which is pretty similar. Is there anyone on this planet who can show me where the source map is on the Eastern Region or NWS webpage? I see this map get generated for various storms and posted by people, yet it's apparently unfindable from the site or google (I get the graphic from google, but not where the graphic is located). Also, Mt. Holly has the map below, but Upton doesn't appear to have a map on their winter weather page, yet clearly Upton's data are in this Eastern Region page. It's all a bit annoying.
