Even doing 20 winters there are only 4 above average. A few are not that far off but still below. (for full disclosure the ten prior to those 20 had six above average)

The median for 10 years is 11.3

The median for 20 years is 10.9

There has been somewhat lesser snowfall recently in DC, and the spread between mean and median snowfall has widened, but not all that dramatically:

Last 100-year mean: 16.7 inches

Last 100-year median: 14.4 inches

Last 30-year mean: 15.6 inches

Last 30-year median: 11.7 inches

In the world of reality...

Nothing is screaming more than a pedestrian event at this point if anything. Reality is that many are hugging some models with an uninpressive track record. Theres still a couple days to hammer this down though. Shame as the EURO and others aren't on the wagon.

the euro is on the wagon pretty much

living on the edge is never good. we need north trends and not just random well-matched blips. oh so slight chance there is some phase of the streams to give a mod event but it's much more likely we either get a general light snow, rain or a miss to the south. there's just not much real upward mobility unless you believe in miracles.

from what I've seen out of the models that really dig the phase i.e.- GGEM, p006 of the GFS :weenie: , etc, is that theyre pretty good events, on the order of 7-9... but thats in the weenie realm and pretty much the ceiling of where this could go... I'm just hoping for an inch

i would hope for an expansive light area of precip with maybe a few bands that bullseye someone to like .25". caveat is the euro did move considerably north and if it did so again we could have a solid ~.2-.25" across the area. the pattern definitely argues more for squashing than being amazing.. but sometimes luck really breaks hard. we'd probably want to see that convincingly soon...

Not sure anywhere north of EZF even gets flurries on the NAM. Sharp cut off events are painful. I am usually on the south side of those watching MD cash in.

Starting with the GFS. GGEM is prob overdoing and way wrong... didn't check the UKIE though I think Will said it was okay... a Euro hold would be nice with a slightly cooler profile

The Ukie i think showed an inch or 2 for our area, i think it is not unreasonable to hope we finally get a break around here and end up with 2".

I think its unreasonable to expect more than a dusting right now IMO. the NAM is supposedly starting to come into its wheelhouse... and being shutout on it is not a good start for the 00z model suite.

I do not even expect flurries, i said hope. Actually where i am for the weekend i expect to at least see some flurries.

Eh, the event is still more than 48 hours out which is outside the NAM's wheelhouse and on top of that, it has had an absolutely atrocious winter so far. I wouldn't put expectations much higher than a coating either, but the reason wouldn't be because of what the NAM shows right now.

The SREFs actually do have like 10% chace of an inch for DC metro which is not bad in this marginal setup at this time range. Down toward CHO its in the 25-30% range.

A general light snow would be fine with me. It's not like I think we can get a foot.

You mentioned a complex pattern earlier, and the models have certainly had difficulties the last few days. I wonder how close we'll have to get for the models to get a good handle on this thing.
