Abnormal accumulation gradient

[WEATHER53]

Even considering the well known rain snow line this one was nontypical. From 7" in Germantown to 5" at Dulles and a lot of 6-8 out west and north to quickly down to 2" in Wheaton and Silver Spring to an inch in DC to bare ground for most of PG Co. and points east and south of. Probably only 30% of the metro area received 4" of snow or more. The storm on this date last year was a uniform 6" and I think a much bigger deal. As we discussed, the part two phase scenario does not work well for DC but usually does for points further north and it looks like for the MD/PA border and north and northeast a very impressive event is underway while DC is now under benchmark 30.00 barometer with ene breezes and not a lot of life showing up for that nc/va secondary, looks more like it's forming off delaware, I doubt DCA receives over another 1", such that of the main three ob stations aeound here, Andrews, IAD and DCA, two out of the three will receive 3" or less of total accumulation. I admit the bust on my part, historic event this is not.

Here's another unexplainable quirk. A guy who lives in northern Washington Co. on the border with Frederick Co. and at an elevation of over 1000 feet reported ONLY 1 inch of sleet/freezing rain in the overnight and early morning hours. Explain that! Makes absolutely no sense to me.

Quite a huge dissapointment here in Alexandria. Still hoping for a miracle tonight- just give me a 6 hour period of steady snow at this point with a few inches and I will walk away happy- otherwise- well its a tough pill to swallow!

I think you stand a good chance of accumulating snow overnight tonight and Sat morning. Secondary low moving in from west of the apps will drag colder air aloft and at the surface as it merges with the low on the coast.

[jtuckermartin]

That secondary is my hope as well! I can remember several that have given DC more snow than anticipated in the past so still a chance of something happening. I'm also still trying to hold out hope that we get into some of the developing coastals precip and can really get a good snow going!

Slight WAA overnight.

I'm at 1,100'... over 1,000' below Hot Springs. Typically with winter FROPA, WREL will be at least 7° warmer due to Hot Spring's elevation. Last night: 3° difference. Slight difference that makes a big difference when floating around 31°

Have picked up almost 3/4" in heavy burst since 8pm, up to around 1.5 fro both events, but looks real sporadic the rest of the way. Great event for Phillie and north, pretty much garden varielty for most of DC, secondary was a flop.
