Yes, Feb 20-21 2015. One of my favorite storms as a young weenie. That was near the peak of our arctic blast, and so when precip arrived, temps were still in the mid teens for most across the area. Took a substantial amount of precip until it finally changed over, with 6"+ from IAD west, as well as a glacier on top of it. Pretty sure temps rocketed the day after, but the snowpack was encased pretty well. In fact some areas maintained that snowpack from then until after the March 5-6 snowstorm (another personal favorite). 

That was a VERY memorable February. One of the few times I remember seeing a negative air temperature around here. And Alaska was very warm.

in my opinion no..it hasnt only trended south, its also a weak piece of crap generally now..There just no spacing for it to really develop anymore between this wave and then saturday

euro shows mixed precip for the first time since we started tracking this storm....on the day of the storm...wow

[North Balti Zen]

38/26 in my part of Balt City. Glancing at radar, trajectory looks...decent (for DC north folks) for where precip is currently occurring?

Thru 7a tmrw. Short pump screwed.

Euro caving to the NAM again.  When did the NAM become so good?  Was it always this good and we just ignored it?

Maybe its better in a la nina winter when everything seems to trend warmer and/or north in the last 24 hours lol.  It was always usually too amped and wet from what I remember but I guess maybe its corrected some of that

Just going off memory here, could be wrong, but I think this is the third event in a row where it's had the right idea first for our area.

Euro complete whiff on Wave 2 for EZF and north...

[WxUSAF]

925 and 850 stay below zero in DC going by the 6hr panels at least. Maybe it sneaks warmer near 8-9z when the NAM and RGEM had the mix line reach its northernmost point, but I can’t tell. Solid euro run for MD.

Boy that south trend really hurt MD

2010 with the last blizzard is the last I can remember for this area. For me, there was a really nice surprise in New York on November 15, 2018. But yeah busting low or totally is usually the way.

Your snow was supposed to come mostly from the 2nd wave which got suppressed too far south.

42 and partly sunny.Not a snowball’s chance in DC proper does wave 2 come north.

On the euro but I kinda thought it was off it’s rocker from the beginning. I think the gfs and NAM was always indicating problems with the first wave. But I thought the second would get you as the cold pressed. Ended up pressing too much and squashed it.

Wow. Just wow. Definitely one of the biggest model fails I've seen since boxing day 2011, in terms of trajectory whiffs. 

I swear the models used to be better than this.

Just updated my snow plow contract guy...My thoughts are 2-4" for metro Baltimore, Potential for 5-6" especially just north of the city along a line from Frederick-Westminster-Hunt Valley-Bel Air..mainly from 10PM-8AM...thats my story and Im sticking to it!

For DC, the "always reliable" precip type indicator shows snow beginning just before 00 UT with mixing near DC from 7-11 UT. 

[snowfan]

If the euro is going to bust at this range, then you gotta throw your hands in the air. We’re, what, 7 hours from this starting?

Imo there was no way both waves were going to be legit and hit the same area. With the first wave stronger, (and confluence to our NE not as strong as advertised, esp on the Euro) it goes norther, and in its wake it pulls the boundary further south. Had the lead wave been a weak pos, I think the second one would have probably been good for N and C VA and much of MD, DE.

[SnowGolfBro]

Updating expectations to snow TV for wave 1 and flurries for wave 2.  He’ll of a hobby we have here boys and girls.
