needbiggerboat Posted January 24, 2016 Share Posted January 24, 2016 good work by the obs and measuring crews at IAD. they are buttoned up and really dedicated to quality and accuracy. Link to comment Share on other sites More sharing options...
McQuackleton Posted January 24, 2016 Share Posted January 24, 2016 Looks like the last real gasp for DCA is moving through. There's one band behind it. Link to comment Share on other sites More sharing options...
MN Transplant Posted January 24, 2016 Share Posted January 24, 2016 Wow. DCA gets 0.13 from 7 to 1, and 0.14 from 1 to 7. Wut? They had 4 obs of heavy snow! something is wrong here!! Two things here: 1) The heavy snow obs are based on precipitation falling and visibility, 2) the automated gauges are prone to undercatch, especially during windy conditions.

Scarlet Pimpernel Posted January 24, 2016 Share Posted January 24, 2016 Going with 24.0 where I am for pretty much a final tally. Very difficult to get a truly accurate measure but think this is reasonable given some other nearby reports in here. I probably had some degree of compaction and stuff drifting/blowing about into and out of various measuring spots. Plus, not going to count what left over bit may have fallen since 7PM. Probably all averages out in the end. So, this tops Snowmageddon for me by a little bit. But will say as a whole this storm was better (but not by too much)...more wind and drifting, and colder temperatures. Duration was longer too. Worthy of the new crown.

colonelaureliano1 Posted January 24, 2016 Share Posted January 24, 2016 Living right next to BWI, being able to see the airport if I walk 5 minutes up my street, we never truly got dryslotted, we had small flakes but it kept going all day. I've been taking 6 hour measurements on a board, and although I wasn't confident enough to post them, BWI's totals have been fairly consistent if about a half inch to an inch higher than mine, but they have a slightly higher elevation. Maybe they had some snow blow onto their measurements but its hard for me to say they are wrong. There was a steady slow accumulation even during the lull.

aldie 22 Posted January 24, 2016 Share Posted January 24, 2016 Whats your total? Has to be near 28, 30? I'm on a farm with wide open spaces so the drifting is ridiculous. I would say based on several measurements I found a low of 27" and a high of 34" lol. I think 28-30" is about right. How did you do? Link to comment Share on other sites More sharing options...

usedtobe Posted January 24, 2016 Share Posted January 24, 2016 Not only that. They're reporting 3.8 inches since 7 AM. Sure we got semi-dry-slotted for a few hours in there, but it never stopped snowing. Not for a second. And yet, through 13 hours of snow, including multiple heavy bands that lasted for hours, they picked up under 4 inches. The DCA defenders in this thread who have buddies who work there or whatever can say what they like, but that's a bogus measurement that is not supported by a single observation point anywhere in the region. And this same thing happened the last major storm, and the one before that, and the one before that, and the one before that. Maybe there was an error, and maybe they'll correct it. I hope they do. But if they stick with this current number, that's a disservice to our region. It is bizarre as I ended up with a little over 5 from the final banding and DCA had better echoes than I did.

DCWeatherGuy Posted January 24, 2016 Share Posted January 24, 2016 That's a pretty damning read. And I'd bet that they followed the protocol overnight and abandoned it this morning. Their 14" total at 7am was reasonable and within an inch of what a lot of people in the immediate area were reporting. And then it went completely off the rails. I joked earlier about the Day Shift screwing up the Night Shift's good work, but maybe that's really what happened. Link to comment Share on other sites More sharing options...

Bob Chill Posted January 24, 2016 Share Posted January 24, 2016 Last band is quietly snowing itself out overhead. Last 3 inches have been pure Colorado powder. 30 straight hours of snow with no breaks. Cold to start and cold to finish. Definitely my favorite storm and a benchmark. I have a lot of work to do tomorrow and I'm already sore. Lol ETA: All 3 airports and almost all MA peeps beat annual climo today! Link to comment Share on other sites More sharing options...

winterymix Posted January 24, 2016 Share Posted January 24, 2016 DCA's 1z ob has a comment :"SOME DATA ABOVE MAY BE INACCURATE!!!!" Wouldn't a scientific approach to knowing the DCA snow total be the following? Determine a statistical mean of ratios (per six hour intervals) for several locations near DCA and use those ratios to estimate the total snowfall based upon six hour liquid measurements taken at DCA. Exclude six hour intervals when snow was absent or mixed at DCA. Long story short, for each six hours that DCA had accumulating snow, use the mean of ratios and the DCA liquid measurements for each six hour interval that had snow accumulation and add up those calcs.

Let them make the zoo have an official weather station for DC and outsource their measurements to people who care about science. Link to comment Share on other sites More sharing options...

True but snow is supposed to be measured on snow board every 6 hours with the snow board cleaned after each 6 hour measurement. I have to admit I don't follow the guidlines so I proably under measure but I'm not an official measurement. It's discouraging that DCA often seems to get it wrong and this time, maybe more than most Link to comment Share on other sites More sharing options...
jnis Posted January 24, 2016 Share Posted January 24, 2016 I'm going with 24" but low confidence in that measurement...it looks like more as I walked down my road with the huge drifts and 4'-5' snow berms blocking people's driveways. Link to comment Share on other sites More sharing options...
Bob Chill Posted January 24, 2016 Share Posted January 24, 2016 What was your total? I had a rough measuring day. I had around 23" or so around 1pm. Local coops had the same.
