    June Discobs Thread

    Point of Rocks has just verified the highest flood stage since Fran's aftermath in 9/96. It's going to be close at Little Falls between tonight's crest and 3/15/10-- forecast is still for surpassing 3/15/10 to be the highest flood since 9/96. Georgetown should get close to the 4/11 level that ruined all those harbor businesses and cars in the garage when the flood walls were not raised. This is a once-a-decade type main-stem Potomac River flood.

    Noteable Potomac River flooding: https://water.weather.gov/ahps2/forecasts.php?wfo=lwx Highest predicted crests since Fran (9/96) at Little Falls and Point of Rocks, for example.

    April Mid/Long Range & Disco

    86 was worse relative to climo the further north you go, it looks like. It was double this season’s total at DCA and hit average with a nice active February.

    Combining HECS/MECS totals across IAD/DCA/BWI- The Top 10

    I assumed that was a conversion thing. I think maybe they convert to metric first and then convert back to inches from the metric value? If you're not trying to go back to the 80's and earlier, here's a *great* site to sift through-- airport totals are included: http://www.jhuapl.edu/weather/education/ACONdata.html Given where you've been drilling down in terms of data, I think you'll really enjoy going through the "Precipitation" pdf's for many winters past. (BWI's total for 12/18-19/09 got downward revised to 18" much later in the season-- the only wrong total I'm aware of.) And, if you're looking for an easy place to catch all the stats (high, low, precip, snowfall, snow depth, max wind, max wind gust, temp departures from average) about winters 13/14, 14/15, and 15/16, you should familiarize yourself with the NWS forecast offices' climate pages: http://w2.weather.gov/climate/index.php?wfo=lwx Select (CF6), the airport you want, then Archived Data. Then choose the month. They only keep a certain number of months backwards in time, so you have to save the expiring months by copying and pasting into whatever format you want. Let me know if you'd like CF6's for the 09/10 winter; I have those saved.

    Mid-Atlantic snow totals for winter 2017/18

    10.9"

    April 7-8 snow event

    Yup the snow total controversies are well known, and we were impressed by the efforts by those who posted on EasternWX and here to get storm totals revised by AKQ. IIRC, they managed to convince AKQ to revise 1/30/10 upward, but AKQ wouldn’t budge on 1/23/16. For DC, it’s the same complaint about DCA all the time. But we’re stuck with both sites being the official one.

    April 7-8 snow event

    I think he's talking about official records from the airport, in the same way people would be referring to DCA when they're talking about DC snow records. KRIC has not reported a 12"+ snowstorm since 2/83, even though 1/96, 1/00, and 1/16 all had >12"+ reports in the metro region. 1/96 in particular seemed like an atrociously low total at 9.5" (the 2.5" on 1/9 was from the clipper).

    Yes, the distribution has been weird with very specific zones particularly under-performing relative to seasonal averages. But we've seen the general idea before, in winters like 04/05 and 10/11, when people in the northeast who end up well above climo will remember the winter as snowy while those further south will remember the winter as a stinker.

    NYC cleared 40" and is 15.5" above average snowfall for the season. Philadelphia is running almost 8" above average snowfall for the season. DC is at ~50% of average. LOL at posters from those areas in here fretting about model runs as if we are all in it together.

    April 7-8 snow event

    The surface temp panel for 18Z on Saturday is even more absurd on this run. It’s verbatim *colder* than what the models were showing (and what more or less verified) at the same time of day for our 3/21 snow event.

    2018 Mid-Atlantic Reunion & Reconciliation

    Well, 4/21 doesn’t work for our friend wxdude64. I just got back into the area after travel. Can we do another April Saturday like 4/14 or 4/28? For balance of travel for different contributors, I agree that the meetup should be in the DC metro area. I met lots of you in the Rockville meeting and I would like to reunite.

    Winter did return, just super late. IAD: 3/20/1990- 2.2", 3/24/1990- 3.0", 4/6-7/1990- 3.8"

    March 20-21 Storm Banter and Party Thread

    I am just guessing and I may be totally wrong— Maybe you don’t know *who* the mods are in this subforum? Because the mods themselves have posted often in various threads encouraging people to knock it off with the bad posts. And a certain poster reacting aggressively to a mod’s post in this very thread this morning started the whole new exchange.

    You and I have discussed the storm before— I’m surprised it didn’t stick on roads predawn where you are but I don’t remember our conclusion. The pictures from Wheaton and Savage in this article are the road coverage I’m talking about: https://www.washingtonpost.com/news/capital-weather-gang/wp/2013/03/25/beautiful-spring-snow-blankets-washington-d-c-area/?utm_term=.7693e6c5c95f I’m guessing this was a storm that varied neighborhood by neighborhood.
