So new snow would be 1.5 to cocorahs with the snow LE. Now if you not home and couldn't measure the 1.5" and then it rained and it was .2" when you got home, then you would report .2" From Cocorahs One of the difficulties with accurate and consistent snowfall measurement is related to the melting, settling, or evaporation of snow before you have a chance to measure it (especially in the Fall and Spring). Please try to do a measurement as close in time to when the storm ends as possible. Don't wait until 7AM if the snow ended the previous day. During long-duration snowfalls, you may choose to measure and clear the snowboard every six hours. The total snowfall would then be the summation of the different measurements Backedge is right on here, as are the others in the conversation. You want to try to catch those “maximum” accumulations before any melting, and that’s what you report to CoCoRaHS. The peak of depth indicates what really happened and is a representation of the event, but if you don’t report that, it’s as if it never really happened. Since I can’t always be home due to work, travel, etc., that’s why I specifically set up my webcam with a close-in zoom on a measurement stick. I can check in on that to know if there was any melting, settling, or whatever. Here’s a shot from my webcam today when I was monitoring this storm while at work: Link to comment Share on other sites More sharing options...

Thanks, yeah I've been doing that as well although I think only one, maybe two events have gone longer than 6 hours this season lol Link to comment Share on other sites More sharing options...

It’s actually been a while since we’ve had a decent January, but this one is doing well thus far - we’re only a third of the way through the month and this January already has seen more snowfall that any of the previous seven Januarys had in total. We’re not quite at 2007-2008 or 2008-2009 pace overall, but with this latest event this season seems like it wants to try to at least give them a run for their money.

The total snowfall would then be the summation of the different measurements That's the way to measure how much snow actually fell. However, if you enter the depth on the ground, that's as it stands at observation time. A crazy scenario- bare ground on, say, Dec. 10 at 7 AM. Later that morning a quick 2" falls, but by sunset it's gone. Then 3" new is on the board at the 7 AM obs time on 12/11. One would report 5" snowfall but 3" depth. If one captured LE for both the 2" and the 3", the sum would be entered. If it were me and I was unable to get the 2" LE but had the 3" LE, I'd not report LE at all.

Right, its possible to get say 3" new snow and then it rains and at 7am you have 3" new and 0" depth. Regarding the bolded, I would only report the LE if I added a note in the observations notes section saying i only got the LE for 3" of the 5".

This added a good shot of QPF to the mountain... despite some great fluff during the second half, the high winds packed it a bit. I bet the mountain added a good 1.75-2.0" of liquid equivalent to the snowpack. As of Tuesday before the storm I had 26" and 6.5" of water at the 1,500ft elevation. Be interesting to see the total liquid in the pack during the next survey. That's a healthy refresher to finally get us off that ice crust from the cutters during the holidays.

That ice is the real problem, it’s like hitting cement. Happy that the mountains are back in good condition even if I’m not partaking for a while. The entire spine did well with this event.

The snow banks up at the resort look like what 36-40" on the ground would look like now. Totally different world up there in that pocket. Great CAD on the 1,500ft bench on the east slope so the snow never melts and it gets a lot of precip. Such a weenie location the base area of the ski resort is.

J.Spin Posted January 12, 2019 Share Posted January 12, 2019 Event totals: 22.5” Snow/1.64” L.E. The clouds have just about cleared out here now and the snow has stopped, so that closes the books on this storm and the numbers above represent the final storm totals. In terms of snowfall, this storm has now taken the top spot for this season at our location, beating out Winter Storm Bruce from the end of November. Details from the 6:00 P.M. Waterbury observations: New Snow: 0.2 inches New Liquid: 0.01 inches Snow/Water Ratio: 20.0 Snow Density: 5.0% H2O Temperature: -1.1 F Sky: Mostly Clear Snow at the stake: 24.0 inches Link to comment Share on other sites More sharing options...
