Off an on flurries, even a period of TV Snow™ earlier this afternoon in Reisterstown. We got a solid snow pack and it doesn't seem like it'll go anywhere over the next week. Very nice.

21 with freezing drizzle. Lake is completely frozen...saw a few snow mobiles driving across the lake and a handful of ice fishers.

Here’s a picture from 219 looking towards Wisp. 7684ac912ca43cb3c4126f3d4cea484a.jpg

Most winters aren't nice to DC, but this one hates them the most.

Rhoadesville, VA:  final measurement on the board at 0430hrs, 6.3"

Some notable hours and measurements:

2230hrs 11FEB: 1.6"

2330: 2.1"

0030hrs 12FEB: 3.0"

0130: 4.5"

0230: 6.0"

Had significant periods of severely rimed 'flakes' and sig periods of mixed ZR/PL/SN-. Easily lost between 1 to 2 inches of accumulation. 

 

Edit: had steady, accumulating SN/SN- until 0410. A little compaction was noted before the measurement at 0430.

Wow after midnight was really rocking. I went to bed at 11:30 but saw the radar continuing to light up to the West. Should've stayed up!

Yes. I was playing with two of my dogs imfy at ~2345hrs; one jumped a deer, they hit the woods for two hours, and I walked after em.  Went back to the board every 50-70 mins so those measurements are up to 10min from a true hourly measurement (even tho that's not the official way to measure anyway. I just like to see hourlies when it's around SN+)

So based on my analysis, and the various vectors relevant to current atmospheric conditions and trends (past, present, and future), I believe that the precipitation shield is traveling at approximately a 30 degree northeasterly angle relative to the magnetic poles (not accounting for flat map distortion or curvature of the earth).  Therefore, based on the observable rates and airborne buoys engineered for data collection purposes, in addition to geometric conditions, the immediate D.C. area, including areas slightly north, south, east, and west at varying distances from a central radius, should expect somewhere in the area of 16" to 20" inches.

Of rain.

Something went wrong. I only received about a flurry and a half of snow instead of the 20 inches of rain like was promised.

Models are not forecasts.  They're tools.

Going with 4.3” total for the two days based on the amount added by Thursday mornings snow shower that moved though.

I just emptied my CoCoRaHS, which I take much more seriously than I do my backyard snow measurements, and had 0.42” liquid equivalent.

Almost an exact 10:1 ratio. It’s nice when things work out
