Snow increasing throughout region

By Jason Samenow

* Winter Weather Advisory for northern metro area (map) *
* Winter Storm Warning for District and W, S & E suburbs (map) *

*** Storm timeline and FAQs | Accumulation reports ***

Update, as of 11:30 a.m.: Current indications are that totals will be a little higher than recently expected. A general 4-8" snowfall appears increasingly likely across much of the area, with 4" being more common in places like central and northern Montgomery County, Md., and the higher totals near and south of of the Beltway in Virginia. As always, some totals just above or just below this range are also possible. 1" of snow has fallen at National Airport thus far (through 11 a.m.) with temperatures in the teens.

Update, as of 10:20 a.m.: NWS has upgraded Winter Weather Advisory to Winter Storm Warning for the District as well as Fairfax, Anne Arundel, Prince George's counties and is calling for 4-6" in these locations.

Update, as of 10:00 a.m.: A light, fluffy snow has overspread a good part of the metro region, with moderate snow already impacting the southern suburbs. In northern suburbs, just light snow and flurries have begun -- but snow should increase gradually in coverage and intensity even there.

With temperatures near and below 20 degrees, snow is sticking to everything. South of the metro region several inches have already accumulated. Reports around Charlottesville, Va. indicate around 4" has already fallen there (as of 10 a.m.). Generally, 3-6" of snow are likely in the metro region by evening, with some locally higher amounts not out of the question, particularly south of the District. (See update above). North of Montgomery county, slightly lesser amounts are likely, on the order of 1-3". Snowfall rates will be moderate to even heavy at times (especially south) this afternoon, so use caution traveling. Please comment with your snowfall reports and vote in our poll below.

@hobbes

There's still a pretty sharp northern cutoff...but models have been trending wetter in and around the immediate metro region. Considering how cold it is and the high snow to liquid ratios, some significant totals are possible, especially south of the beltway.

I'm really surprised how quickly we went from tiny flakes to pretty heavy snow. It's only been snowing about 30-45 minutes and we've easily got half an inch on the ground. This reminds me a lot of 12/19.

Repeat of earlier post:

WRF projects 8-10 inches for Arlington County, a foot south of here, 18-20 inches for Richmond. Storm may EXCEED expectations, but is proving a "bust" in North and South Carolina, except in the mountains where snow is tapering off by now.

Not sure if thundersnow is in the picture.

When I woke up at 9:30, there were a few flurries and a dry ground here in Arlington. One hour later, and the air is filled thickly with falling snow and everything, and i mean everything, is coated. So lovely!

I can already hear cars skidding on Lee Highway, which runs by my place, so be careful driving out there. Or, better yet, stay home with a good book and mug of cocoa!

Snowing pretty hard in close-in Silver Spring. Already a nice coating (maybe an inch) on everything, especially the roads. Very fluffy and light snow so far, the "silent" kind.

This feels like like an event that will wind up on the higher ends of the prediction ranges.

Wow - I slept in this morning. We're getting rocked here in G'town right now, streets covered and snowing hard. And of course with the temps in the high teens, every single flake is sticking. Is anybody else "concerned" about a coastal low developing off OBX?

It was interesting to track the forecasting for this snowstorm and how the models drifted the storm track south then back north into our region over the last week. It was indeed a tricky snowstorm.

How often is the temperature 18 degrees with heavy snow falling in Washington, DC? How exciting!

Snow's coming down as fast as it did 12/19, but the consistency seems different; more powdery, maybe? It just doesn't seem as 'thick' to me this time.

Can anyone else see this storm blowing up off the east coast then going to hit places like NYC? A scenario like that would definiatly give us more snow ?

Posted by: cpm2cv | January 30, 2010 11:02 AM | Report abuse

And we can track the snow-band setup via the comments right here. To the west, I am seeing small, light, powdery flakes. JSTF in Lake Linganore to the east reports 'big flakes, all practically plummeting downward' and joann20657 reports a heavy snowfall in Solomons to the southeast.

CWG: Am I correct in my guess that the heaviest snow is bumping up against the fall line/I95? If so, what role does the fall line play in the tracks of such snowstorms? (We all blame I95, but I95 runs along the fall line.)

Like JSTF, I'm seeing bigger flakes and steady downfall within the last ten-twenty minutes. I'm in downtown Frederick. Very happy to be getting some snow outta this storm, after thinking it'd miss to the south!

Centreville VA 19 degrees here with snow that started mid-morning. We have over an inch on the ground. The steady, moderate snow is going back & forth between super fine flakes to larger flakes. Interested to see if we'll get some periods of very heavy snow this afternoon...I think that will make all the difference between total accumulations of 3-4 inches compared to 6 or even more.

Husband and I did a planned hospital test-drive this morning without being aware of how fast things were going to get bad! (I'm 37 weeks pregnant.) We're in Reston, which had maybe just under an inch on the ground half an hour ago, but still falling. The drive to Falls Church on the Dulles Tollway and 495 was less than pleasant, near whiteout conditions on the way back, and no sign of plows or salters until we were back in Reston at 10:30. The couple trucks we did see near home were private contractors, not VDOT.

Moral of the story: if you must go out today, drive safe, be careful, and be mindful of road conditions and other drivers. If you don't have to be out there, stay home and enjoy the snow!

CWG: I've noticed on the radar today and during the December storm some occasional dry patches within the snow bands originating near and around the Virginia and West Virginia mountains. My question: do these small dry areas near the mountains actually represent dry air in the snow bands due to the topography or are the mountains impacting the radar signal?

Posted by: snowlover | January 30, 2010 11:47 AM | Report abuse

I'm assuming those dry spots are related to the mountains and do not necessarily represent precipitation. Although the Shenandoah Valley is one of the driest spots on the East Coast, every storm that comes seems to blow around those parts on radar. In Colorado, the regular radar shown on the Weather Channel rarely picks up precip in the mountains even if there is a blizzard going on.

I would also be interested in knowing the answer to this question.

Haven't seen a D-2 bus in the north (hilly) section of Glover Park where I live, in hours. Even treated streets are freezing up, with temps in the teens. Looks like the storm center is off the Georgia coast, but folks with more sophisticated tracking equipment can pinpoint this better.

Probably only a matter of time before the local TV crews start doing their shivering standup reports.

Hi Ian-CapitalWeatherGang and others,

I'd like to do some more investigating into why precipitation (almost always snow measurements but sometimes rain too) totals at DCA seem to almost be lower than its immediate surroundings.

You have stated that the liquid number at DCA was way off with the big snowstorm last month. Do you have any more insight on that you would like to share?

Also, do you know where at DCA do they do the precipitation measurements?

The funny thing about events with only a 10% probability is that they tend to occur 10% of the time. Glad to know that the 10% chance of 6 inches of snow in DC may indeed occur.

Posted by: samdman95 | January 30, 2010 12:53 PM | Report abuse

There was much justifiable discussion before this morning about how even a small shift in the storm track being the difference between very little snow (if any) and a more substantial snowfall in the DC Metro region.

The problem, perhaps misleading aspect of with this explanation alone, is that extension of the heavier snow further north than expected was much less a consequence of any change in the track of the surface low, but rather the dynamics (vertical motion; vorticity advection for geeks) and convergence of moisture between the surface and a few miles aloft. These features are very small scale (30-50 miles or less) and extremely difficult to reliably predict more than 6-12 hours in advance - as witnessed by models beginning to show signs of snow extending more to the north (as reported by CWG) not until late Friday.

In contrast, the the December snowstorm was much larger in scale and, hence much more predictable even several days ahead. The good news is that we have the capability to discriminate before hand the more form less predictable cases.

Reasons I knew this storm would have decent snow accumulations:

1. It was predicted to be a bust. Whatever is predicted, the opposite tends to happen.

2. I am scheduled for a West Wing tour today. Anytime I have plans downtown, we get a storm.

But, it sure is pretty. I have been trying to be a little more athletic lately. I may try some cartwheels and back bends in the snow since Ihave this soft stuff to cushion my falls.

@otavio---I'm with you on this issue of DCA as the place where this area measures snow. I've asked the same question here on CWG and other weather blog and have never had an answer. Why do we measure official snowfall totals in the place that tends to get the least amount? Ian? Steve? Anybody?

Posted by: lilymama | January 30, 2010 1:14 PM | Report abuse

Hey Ian (or other CWGers), I've been lurking some Meteorology forums (like Eastern USWX) and people keep mentioning the possibility of another "big one" next weekend. What do you guys think? I know anything past 3 days out is like reading tea leaves, but from the way people are talking there it seems like we can think about another foot of snow right in DC/MoCo/NoVA. Thoughts?

Posted by: NattyBo1985 | January 30, 2010 1:17 PM | Report abuse

We have been alternating between light and moderate snow in Oakton, VA. Currently it's moderate snow. It appears that we have almost 3", but I haven't measured it yet. Currently, the best snow bands are to our north and south. Hopefully, they will converge on DC. I'm heading out to take a few photos.

Here in Silver Spring we have at least 3 (maybe 4) inches. A trip to Prince William Forest Park was fine until I spun out on the I-95 exit ramp (I and the car are fine). But the group decided not to go into the park. Visibility was 1 mile on the way down.

Coming back the highway speed was about 25-30 inside the Beltway, with the right lane on I-395 under-traveled and with so-so traction. Visibility was under half a mile much of the way. I spun out twice on East-West Highway in Silver Spring west of 16th Street. Thanks goodness for anti-lock brakes and light traffic.

Now I'm safe inside, drinking tea and soup, enjoying the snowfall.

What a great Saturday!

Posted by: Snowlover2 | January 30, 2010 1:21 PM | Report abuse

I have also asked about the DCA issue with poor answers (not a slight on this board, Im speaking more generally). I think someone once said they measure on a roof. Hello? Wind? Regardless, it should not be measured at the epicenter of the heat island or an area that is uncharacteristically (WOW that is a long word) open in the sense that there are no trees or anything around...except wind.

The news always reports our areas weather based on the DCA readings, so I hear things on TWC like 2" in DC and it makes me frustrated when I see 6" on the ground.

You would think NWS has weather geeks that frequent the DCA weather station that would have figured this issue out over all these years.

@lilymama

The problem is that NWS would need to set up another official observing station in D.C. if they didn't use National. The next logical choice in terms of official area of observing stations is Dulles. But that would often be just as un-reprsentative of the District as a whole as National (on the high end instead of the low end). Personally, I think they should set up a station on the grounds of the White House.

I turned on The Weather Channel just to see what they were presently hyping. Leatherfaced Jim Cantore (he is so full of himself) is standing with a shovel in a measly inch of snow and ice somewhere in Charlotte. Looks like they missed the boat on that prediction.

That network has hemorrhaged their credibility over the past decade. Based on their over the top reporting you'd think the whole world is centered around Atlanta, where they're based. They can't mention a mudslide in California, a blizzard in North Dakota or a nor'easter in Maine without tying it in to boring Atlanta.

They also seem to have it in for DC. They always inflate DC's temps, making it seem much warmer than it really is. Tomorrow they forecast the high to be 37 while Norfolk is only 30! The new meteorologist (Santos?) broke from the anti-DC script and even admitted that the high of 37 for Sunday seemed to be a mistake.

And they use the word "folks" instead of the proper word "people" every chance they get. Yes, I'm rather stirred up right now by the "folks" at TWC.

We went to Falls Church this morning for my appt. I should have had my head examined while I was there (for going out in this mess). We had about 1/2" in Dumfries about 8am when we looked outside. Roads were surprisingly good in Prince William when we left, but Fairfax roads were awful. All the roads were HORRIBLE when we came back. But my Altima --and hubby (we'll call him 'southbridgedad') rocked it out in the snow. Got home about 12:30. I'm staying put the rest of the day. Got my Earl Grey tea and I'm a happy babe.

@tsqnova Maybe Comcast buying NBC will lead to a makeover for the Weather Channel? Too much "When weather made history" and not enough live updates of the weather.

Thanks, Dan, for sharing your opinion on a better location for DC's official weather station.

We just need to get some heavyweights behind our effort. We need to get the project funded, and then move it and be done.

Just because we've been taking measurements from National for like forever, it doesn't mean that it's the ideal spot for DC's official weather station.

A comment on here was made that the snow measurements are being taken on a roof at DCA? Nice!

I'd still like to know where the spot is from someone official. At the north end of the airport? At the southern end? More near the river? It seems like it's a secret! I may write a letter to my Congressperson about for the answer.

Someone mentioned the Naval Observatory as a location for DC's official weather station. Sounds interesting. The White House grounds do too.

"Current indications are that totals will be a little higher than recently expected.'

Guys, I hate to appear nasty, but the truth is that - notwitstanding a battery of high tech gear - you and every forecaster in this area completely blew this forecast. So, quit embarrassing yourselves by speculating about snow totals. I live in Annandale and snow has been falling here at the rate of an inch per hour. Misleading comments about the snow being "a little higher" than expected just illustrate that we can't rely on you or your counterparts for accurate information.

@Tom-Fairfax "...you and every forecaster in this area completely blew this forecast. So, quit embarrassing yourselves by speculating about snow totals...."

I think CWG did an excellent job of managing expectations all week on this one. It was a very tricky forecast in that the high to the north was pushing dry air into the region and suppressing the low on a mid-Atlantic track. Every piece that crossed CWG this week highlighted this fact, and that predicting snowfall totals was going to be tricky.

The fact is, the models handled the snowfall pretty well in the central Virginia area.

Tom-Fairfax, it's disingenuous and unfair to lump CWG in with their weather "counterparts" when it comes to calling a storm like this. If anything, CWG *never* resorts to hype, unlike SemiAccuWeather.com and a host of other paid wx sites, and in fact, they tend to rely on "nowcasting" once we get closer to and actually into a wx event. I rely on CWG for the most reliable, and constantly updated forecast, especially during a difficult-to-forecast event such as this one. You need to cut 'em a break - every met I've heard or read had trouble calling this particular storm...
