The March 5-7 White Lion Obs/Nowcasting Thread

[WinterWxLuvr]

Taken half hour ago. Basically quit now.

[kmill14]

Heard a noise suspiciously like a transformer blow then lost power. But it came back on a minute later. Odd, since the grass barely is white.

Same here. We're in Parkfairfax near Shirlington. Happened about 15 minutes ago.

[MN Transplant]

Perfectly said, Hoo.

 

Agree.  Large flakes, but it isn't exactly pounding like you'd want for a 1-2"/hr rate (at least not at 33-34 degrees).

[mitchnick]

wow

but will it be snow is the question

[Snowpocalypse]

*Sigh*...mostly rain.

I'll take the HRRRRRRR for 1,000,000, Alex.

It can't be overstated just how hard this area is to forecast and plan for.  Portions of the DMA are under a foot of snow, and others are in a driving rain storm.  Some have seen snow for hours and not a trace to show for it, and some are approaching 3 inches.  Not only forecasters, but for groups like OPM, etc to try and come up with a single policy/decision for the area is near impossible.

[NoVaWx]

Crazy fat flakes falling very heavily. Everything is instantly white. 1-2" per hour stuff.

[heavensbee]

Back to heavy snow in College Park.

[North Balti Zen]

Everytime someone in Columbia reports rain a little piece of my snow loving soul dies...need you all to flip before I have hope.

[onel0126]

Moderate snow in La Plata with an inch on the ground @ 34. Wind warnings up for Harry Nice Bridge (301 bridge)

[PhineasC]

wow

Looks like many more hours of light rain to come here.

[mattie g]

*Sigh*...mostly rain. 

Damn, dude. Seriously?

[Fozz]

Light rain/snow mix.

Yuck

[Midlo Snow Maker]

Calm before the storm? Hopefully we can get some winds generated for those E of 95

[North Balti Zen]

Damn, dude. Seriously?

 

Yes. The I-95 cooridor from Columbia north to BWI to downtown and up is pure unrelenting rain.

[Skywalker03]

Huge flakes in north Rockville, but I wouldn't call this heavy snow. Maybe moderate at best. Prob closing in on an inch? My side street is covered.

[Ger]

I feel like all of us are accustomed to receiving a long period overrunning or WAA with our KUs; and less familiar with Nor'Easter-type (e.g. moisture fetch from the Atlantic).

Why?? It could be this: this area's geographic location translates to being less prone to the features of a Nor'Easter, particularly a Nor'Easter that is undergoing rapid intensification. Other places such as NYC and SNE experience this more frequently.

I say this because looking at current radar, it really struck me when comparing our current radar signature to similar signatures I have seen before on NYC or SNE radar. Just a thought.

[das]

It's been snowing moderately for the last two hours and the temp is 31.4F.  During that time, my snow total has gone from 1.9" to 1.9".  Pretty snow but it's just not accumulating.  Maybe this next moderate band will change that.

[mattie g]

Agree.  Large flakes, but it isn't exactly pounding like you'd want for a 1-2"/hr rate (at least not at 33-34 degrees).

Every once in a while it really batters us, but it lets up just enough to bring the rates down to a manageable level for the March sun.

Radar is looking good back into Maryland, though.

[RIC_WX]

Heavy snow now on the east side of Leesburg.  This will accumulate quickly if it continues.

[heavensbee]

...and now the big flakes are gone. Back to rain.

[josh]

CBS' new accumulation map still has 6-9" for immediate DC area.  with 0" on the ground right now, it should be some fun later if it holds true.

[mattie g]

Yes. The I-95 cooridor from Columbia north to BWI to downtown and up is pure unrelenting rain.

'Eff me, that sucks.

[TalcottWx]

On the doorstep... hoping this is going to be a switch to better than a rasn mix

[NovaHoo]

I'm only not calling this heavy snow in Burke right now because, like a figure skating judge, I'm leaving room for some of those 35 dbz returns I'm seeing.

 

Coincidentally, first snow with the Dish Network. Now I see the downside.

[haudidoody]

Light to moderate snow for an hour now and nothing to really show for it, even on grass.

[Ike]

The rain hurts.  I've lost almost an inch of snow since I measured at 7. 

[TalcottWx]

NE Balt it was even rain on 83 north of hunt valley when the echos subsided a half hour ago
