Shockingly solid snow in DC too. Patio furniture caving. 

Mulch whitening.  Down to 32.5/28.  Should be below freezing by 3p at this rate.

Still hanging around 34 on my nearest station, but sure I won’t be too far behind you.

Yeah. It’s not our storm. Maybe the next one

Late next week might be the next one worthy of tracking investment.

[NorthArlington101]

Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
211 PM EST Tue Feb 11 2025

.SYNOPSIS...
Low pressure tracking to our south will continue to bring snow to
the region through tonight. Expect a lull in precipitation on
Wednesday morning as a mid-level dry slot moves overhead. Another
low pressure system brings additional wintry precipitation Wednesday
afternoon through Wednesday night, mainly in the higher elevations.
A cold front crosses the area Thursday afternoon, bringing blustery
conditions. High pressure builds overhead Friday before yet another
low pressure brings precipitation chances to the area for the
weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
Current radar trends remain largely in line with the current
forecast. Snow will continue to drift north and gradually
overspread the region through this afternoon. For now, many
areas are still battling dry air, especially north of the I-64
corridor. So, at least for the next hour or two, still going to
have pretty light rates with small flakes and very little in
terms of accumulation. Over central VA, along and just north of
the I-64 corridor, some heavy snow is ongoing, with report of 6
or more inches up on the Blue Ridge. So, it seems that the
heavier band is setting up about where it was expected to.

Today`s guidance has shown a bit of an upward trend further
north as well, owing to a secondary area of FGEN forcing that is
pretty consistently showing up amongst the guidance. Still not
quite clear where the heavier band of precipitation associated
with this feature will set up, but seems likely that western MD
will now get a few additional inches in response to this. So,
have added them into the warning for the current storm.
Elsewhere, generally between I-66 and I-70, there could be some
isolated higher amounts if this band does develop. For now,
amounts have been ever so slightly increased, but no northward
expansion of Winter Storm Warnings are needed at this time.

Generally speaking, expect a swath of 3-6 inches south of I-70
and 6 to 9 inches south of I-66, with localized amounts up to a
foot up along the Blue Ridge. Additionally, could see some
localized higher amounts towards Highland county on the ridges
there.

The bulk of precipitation will exit the region early Wednesday
morning, but turn into a light drizzle/flurry situation into the
day on Wednesday (see short term below).

Wow! Just a sudden gust of wind from the NE and it's off and running. Snowstorm is moving in.

Just hit 31.9/28.   Ahead of schedule on temps IMO.

SN (borderline SN+) with dendrites mixed in.

[weatherkyle]

34/27, snow 

It’s starting to think about sticking.  I’ll call it the pre-sticking phase of sticking

I’ve lost half a degree in like 15 min and hope to be sub 32 by 3pm. That will help fight that dastardly sun from earlier

[North Balti Zen]

Flurries downtown baltimore looking out my window 20 floors up. No idea what it is like in Monkton.

The preperation stage for the BOOM

[DDweatherman]

reports from the home front it’s borderline SN+ back home in Carroll Valley, 29 degrees. Maybe we can get 2.5-3” outta this
