High-Impact Snowstorm to Paste Metro Area

By Capital Weather Gang

Strong winds, cold temperatures to accompany snow

* Winter Storm Warning 2 p.m. today through 2 p.m. Monday *
* Capital Weather Gang on Twitter | Weather Wall | SnowCam *


Today: Patchy a.m. snow, a break, then snow re-developing later in the afternoon. Mid-30s | Tonight: Snow likely, heavy at times. Becoming windy. Low-to-mid 20s. | Tomorrow: Morning snow, windy and cold. Near 30.

Jump To: Accumulation Map & Timeline | Impact Forecasts | FAQ


A significant winter storm appears likely to blast the metro area with snow late today through tomorrow morning along with strong winds and possibly blowing snow. We're expecting a general 4-8" of snow in the metro area, with greater amounts possible east/southeast and somewhat lesser amounts west/northwest. This is a high-impact storm that will probably cause significant disruptions, including travel delays and school cancellations.


1 PM to 4 PM TODAY
Light snow develops south to north. Not much accumulation. Temps 33-36.
4 PM to 8 PM TODAY
Snow increases in intensity and starts to accumulate. Temps 30-33.
8 PM to 12 AM MON
Snow, heavy at times. Temps 27-30.
12 AM to 4 AM MON
Snow, heavy at times. Temps 23-27.
4 AM to 8 AM MON

How confident are you in your forecast? We're fairly confident that accumulating snow will spread across the region this afternoon and should continue through tomorrow morning. One thing we're not as confident in is the exact amount. Our official forecast is for 4-8 inches for most of the metro area. 6-10"+ is still in play east of I-95 with isolated accumulations of close to a foot possible. These totals may be updated during the day today as slight changes in the storm's position will have a large impact on the location of the heaviest snow bands and total accumulations.

Keep reading for more storm FAQs. Just found us? We're here 24/7/365 -- rain, snow or shine. Visit us at

How much snow will I get at my house? Check out our accumulation map but note storm totals will be very location specific. The snowfall gradient for this storm will be very sharp. Snowfall totals could vary by six inches or more in a span of 30-40 miles. The heaviest of the snows will likely occur just east/southeast of the area. Places like Annapolis and Waldorf, Md., and just east of Fredericksburg, Va., may be the jackpot areas. For the I-95 corridor from Washington to Baltimore, we are forecasting 4-8". Areas in the north and west suburbs like Frederick, Md., and Leesburg, Va., will probably get less snow, but since it will be colder in those spots, the snow may accumulate more quickly.

Could the storm bring more snow than expected? Yes. With snowfall varying so much over relatively short distances, a slight shift of the storm's track to the west could put the immediate metro area in the snowfall bulls-eye, with double digit accumulations not out of the question. Also, we'll need to watch for the potential for localized heavy bands of snow and even thunder snow (a possibility with this energetic storm), which are difficult to predict, but could substantially increase snowfall in isolated areas.

Could it fizzle out and leave us high and dry (or wet)? Yes. Do we think this is a likely scenario? No. But coastal storms are notoriously finicky beasts. All the right circumstances have to come together to produce heavy snowfall. A shift in the storm track to the east could result in snowfall amounts half of what we're currently predicting or even less. We do not think there is much chance this will be a rain storm.

Will we see any of the dreaded wintry mix? While we experienced a wintry mix from the first wave in our weekend storm duo, this second storm should be mostly snow except well to the south and east where some sleet may mix in (and even rain southeast of Richmond).

When will this storm start? Look for the first flakes to fly between 1 and 3 p.m. this afternoon with the heavier stuff arriving as we head toward dusk.

When will the heaviest snow fall? Moderate to heavy snow could begin around dusk. Periods of moderate to heavy snow are possible throughout the night before winding down early Monday morning. From I-95 and to the east, some moderate snow could even linger into mid-morning Monday.

Will the snow stick? For the first hour or two of the storm this afternoon, air and ground temperatures will probably be warm enough that the snow will melt on paved surfaces and mostly accumulate on grassy areas. However, as it becomes dark, the snow picks up, and temperatures drop, snow should begin accumulating on all surfaces, including roads.

What will this mean for Monday morning's commute? Nothing good. While the heaviest of the snow should be out of the area by the time most of us begin our work week, lingering snow may still be falling, especially to the east and northeast. Crews will initially focus on clearing the major roads, so secondary and side roads may be slick, if not snow covered. And strong winds may mean blowing snow.

When will the storm be over for our area? We may still see some light snows Monday morning, especially to the east. By the mid-afternoon hours, the storm for us will be over. We may even see some late-afternoon sun sparkle off the freshly fallen snow.

What's the best thing to do once the storm starts? Anything you want! Take an evening stroll -- everything seems so much quieter when it snows. Turn on your porch light, curl up with a book and beverage of choice and enjoy the scenery. Stay off the roads Sunday night into Monday conditions may become difficult and even dangerous as the night wears on.

What will conditions be like after the storm? Cold and windy -- with the possibility of some blowing snow. Late in the afternoon tomorrow we'll begin to see the clouds break up and move off. By nighttime we'll have some patches of clear skies and temperatures will plummet well into the teens. This cold snap continues Tuesday and Tuesday night as well with temperatures well below normal.

What are other forecast outlets calling for? (as of late Sat. night)...

WUSA-9: 3-6" (Tony Pann's blog)

Gwen Tolbart seemed barely concerned about this storm last night and pretty much blew it off. Good work - I'm sure Sue must be proud of you! Maybe that's why you got demoted to the weekends. Tony Pann is the best of the weekend crew in this area, too bad his cheap station cancelled their weekend morning newscasts. He said he'd be updating his blog this morning though. Chuck Bell on NBC4 is saying at least 6" as of their 6am newscast. While ABC7 doesn't have a Sunday morning newcast of their own, they have morning news at 7am on Newschannel 8, so I'll see what they say. Bring it on!

Yes, Fox blew this one last night big time - relied solely on the NWS forecast (almost verbatim). That's not really forecasting, is it?

I'd fill in that last apple, too. With but an inch we would see widespread 2 hour delays; 6-10 we may see closings for multiple days.

My predictions:

DCA: 9.8
IAD: 4.6
BWI: 11

The 0z Euro increased the QCP amounts and the ratios seem to have increased as well - hopefully my predictions are on the low side!

I'm in the Charlotte area this AM and the forecast is for 5 to 10 inches of snow depending on where you are and when the changeover occurs. Possible thunder is mentioned in the forecast. Also, since the precip could be more convective down here, we could get alternating periods of rain and heavy wet snow today before the changeover to all snow. We already had one thunderstorm around 5 AM with a temp of 34F. What's interesting to me is that the forecasts for CLT and DCA are so similar, especially for Sunday night; that doesn't happen too often, especially in March for 35 degrees north latitude.

The snow we're getting now is from Storm #1... We should have a break later this morning through mid afternoon. Storm #2 may role in a little later than the above timeline...but it should be snowing again by dark.

I know you're all hoping, but unless those temps drop significantly, there will be little accumulation.

I for one am not hoping. Most drivers struggle in the dry pavement; they are terrified of wet, and the snow makes them into jelly.

Even the pedestrians are crazy here. Last snow/ice storm in January I was driving into work at 5 AM, and there was a pedestrian in black walking down the middle of the road. With his back to traffic. Probably because the sidewalks were icy, but!

Anyway, the snow is fun to look at, but I'm hoping for a complete bust.

I suggest a rating scale for weather forecaster on TV and Radio... on a scale of 1-5. If you're a 5, you get to predict anything you want. If you're a 1, you only get to predict what's going to happen in the next hour.

As you get better (accurate forecasts), your rating goes up and you're allowed to forecast longer. If you get worse, (inaccurate forecasts), your rating goes down.

Over a period of 1-3 years, you could then tell how good a weather forecaster is by their score. Crazy idea, but wouldn't that be great?

One nice thing about that first storm is that it moistened up the atmosphere. I imagine precipitation will start hitting the ground immediately, unlike some storms where we lose potentially several inches of snow due to the dryness of the atmosphere!

(Or am I completely wrong on that?)

CWG, what are the odds that this is a total bust (2 or less inches)?

Posted by: samdman95 | March 1, 2009 10:47 AM | Report abuse

I'll give you my FedCast now: Liberal leave. Possibly late arrival also.

It's not gonna close. Those hoping for that will be sorely disappointed. We'd need enough snow to shut down Metro and that's more than 8 inches areawide. And that's just not gonna happen. Sure, some people may see amounts => 8 inches, but it won't be areawide.

So as I posted yesterday, it will be just enough to make the roads a complete mess but not close the Feds. Just like about every other storm we get.

On that note, which one of you snow weenies is gonna shovel my driveway and sidewalk? Since you love snow so much, I expect you'll do it for free, right? :)

Since snow totals r almost always over 4cast, I'll go with DCA 4.6", IAD 4.1", BWI 5.1" & generally 3.5-5.5". Wouldn't b surpised to see some mixing of sleet & rain, it's very difficult 2 get an all snow event in this area. Very light mist in NW Spotsy. 31.7.

Radar showing a large area of rain from Rich down to Ga. moving N., although it's snowing in Miss. Now thinking storm begins as rain & to snow late 2night, keeping snow totals way down. Now going with 1.5-3" of snow. DCA 1.6".IAD 2.7", BWI 2.3"

VTBob - I agree. Does the radar appear to have a NE trend to you? Looking to me like the heaviest precip trying to head that way to me.

Bonus snow...could be thundersnow. Apparent thundersnow in Southern Appalachians acc. to Weather Channel.

Not sure of accumulation totals...some GFS charts trying to intro. WAA and change-over to rain here...540 thickness line north of D.C. If this goes all snow, we could get a huge accumulation, even more than the projected 5-8".

For all the storm naysayers; just check out any eastern U.S. regional radar on loop. You can clearly see the storm getting organized over GA. There is no question that this is a developing storm with plenty of energy. As long as the cold air comes in from the northwest and the storm tragectory continues as forecasted, we are in for a good one. Possibly on the higher end of the forecasted snow totals. These types of systems are historically some of our biggest snow makers. We'll see.

15% chance of a bust...less than 2"


New update post is up...

Posted by: Jason-CapitalWeatherGang | March 1, 2009 11:21 AM | Report abuse

Predicted accumulations:

If all snow: DCA: 8+"
IAD: 4-8+"
BWI: 6-10+"

If WAA [that's warm-air advection!] cuts totals, less snow will fall but we could have a bunch of messy slush to deal with tomorrow.

Thundersnow possible: 6 PM tonight-6 AM tomorrow.

All schools will shut down. Federal offices may close, especially if Metro closes above ground. Tomorrow night's dance @ Chevy Chase Ballroom might be cancelled. There's no dance @ Clarendon Ballroom Tuesday night due to floor refinishing.

Is there a problem with the site - I can only see new posts when i submit one.

Posted by: snowlover | March 1, 2009 11:33 AM | Report abuse

Posted yesterday and received no response. So here it is again:


Looking at the onset of storm #2, it appears we may have issues with precipitation type. Could this storm start out as a mix before the column thickens and changes everything over to all snow?"

Posted by: Hanz1 | March 1, 2009 11:52 AM | Report abuse


Yes-- a little rain or sleet could mix in at the very onset (since afternoon temps are in the mid-30s) of the main batch...but will very quickly change to all snow and temperatures will drop.

We mentioned the possibility of 'thundersnow' in our region tonight. Here is the current observation at Atlanta's Hartsfield Int'l Airport: Heavy snow, visibility 1/4 mile, lightning/thunder observed.

Pretty nifty!

Dulles- 6 inches
DC- 10 inches
BWI- 12 inches

For a change, us snowlovers out here in Snowtown (Leesburg) are on the ouside looking in! I'm hoping for a slightly western jog to the track of course.

Posted by: 4seamed | March 1, 2009 2:03 PM | Report abuse


IAD: 7"
DCA: 9"
BWI: 11"

No snow yet here in Greenbelt, which is a good thing, because it means the storm is not racing up the coast (CWG said this morning to expect the start time to be between 1 and 3 and we're almost at the end of that range). 36.5 degrees.

This is sweet!! I haven't been paying attention and had written our big storm off already. What an awesome surprise! The kids are psyched and we are crossing our fingers on the Fed Cast =) Making ice cubes for the toilet right now!

CWG,I know the center is still down south, but is the center generally where you expected it to be at this time?

Posted by: hortexp | March 1, 2009 3:43 PM | Report abuse

I am in Bethesda, MD near the Beltway at 4:13 PM. It is certainly above the freezing point here.
Any snow that had accumulated from earlier snow flurries has already melted.

Can anyone tell me when it is expected to become cold enough to actually snow rather than rain?

Posted by: captn_ahab | March 1, 2009 4:14 PM | Report abuse

Been out by bike in NE/NW Branch trails. Temp dropping still; 36 degrees by outdoor thermometer. Friend in Annapolis says that fluffy snow is flakes yet in College Park.

Posted by: CollegequaParkian | March 1, 2009 4:47 PM | Report abuse

No flakes yet in Franconia, VA

Posted by: Alexandria2009 | March 1, 2009 4:54 PM | Report abuse


Yes--low is about where we expected it.


It doesn't have to be below freezing to snow at the surface if it's cold aloft--which it is. Once the snow starts, it will bring down some of the cold here to the surface.

If they are predicting a lot of snow, we will get a little. When they predict a little, we get snowed in. Been here since 1967 and I still wonder why they even bother to predict snow or rain accumulation.
This is an unpredictable area.

Posted by: mortified469 | March 1, 2009 9:52 PM | Report abuse

mortified, you are so right.

and yes, just like every other snow we get here it will be enough to make the roads, metro and life miserable but not enough to close down the government which is just really as unfair a weather proposition as i can imagine :(

(not that i dislike work or working, just that surprise days off are so very fun!)
