Your favorite Knickerbocker snowstorm photo?

I am currently working on a Knickerbocker Snowstorm book with Arcadia publishing for their “Images of America” series. I thought I’d poll the readers of the Capital Weather Gang to determine your favorite cover photo.

Grading our 2011-2012 winter forecast

As always, we grade our winter and summer seasonal outlooks in spring and fall respectively. In short, we did poorly this winter with not much of a silver lining. The major consolation being that we can commiserate with the authors of the other winter outlooks we encountered.

Recapping the 2011-12 Snow Potential Index

With D.C.’s first occurrence of three straight 80-degree days in March since 1998, snow is now a distant memory. Capital Weather Gang officially retired Season 2 of the Snow Potential Index (SPI) last Friday, forcing disappointed snow lovers to come to terms with the remarkably warm winter of 2011-2012.

Super snow band blankets central Virginia

As light snow and flurries - of a conversational nature - fly around parts of the D.C. metro area, a narrow band of heavy snow has set up from just west of Charlottesville to just south of Fredericksburg. A winter storm warning for 4-6” of snow has been posted for that region through 1 p.m. today.

March outlook: Warmer than average, low snow chances

The warmer than normal winter is expected to continue into at least the first two weeks of March and will probably last through the month. That doesn’t mean there won’t be quick shots of colder than normal weather but that there is unlikely to be sustained cold. And snowstorms will still probably be hard to come by.

A long, snowy drive south

On Monday, I traveled as far as Charlottesville, to Monticello, then I turned around. I stopped a few times to take photos. Some of the photos, I thought, turned out fairly well so I decided I would share them.

The forecast for the February 19 storm was not a good one for D.C. snow lovers, unless willing to travel. That’s just what two members of the Capital Weather Gang did, and they managed to find some heavy snow.

How accurately was Sunday’s no show snow predicted?

After a largely snowless season, last week there was considerable build-up for the possibility of snow Sunday. But with the exception of Springfield and points south, there wasn’t even a dusting. Some have questioned whether forecasts were overblown for Sunday’s event. But we want to let the record show our forecast was for little or snow in the immediate metro region, starting Friday night.

Update: Still a chance for some “conversational” snow, mainly this evening

Don’t be surprised to see some steady snow, perhaps a coating to an inch in D.C.’s southern suburbs this evening. Around the beltway, I’d expect any flakes to be more conversational, with little or no accumulation. The most likely timing would be between 6 and 10 p.m. tonight. North of town, probably just flurries, if that.

Sunday snow chances bleak

It’s desperation time for snow lovers. The latest models have shifted the northern edge of Sunday’s simulated precipitation south and do not indicate any snow for the District. And even snow prospects south of the District are iffy.

Sunday snow probably won’t be much, but minor forecast changes still possible

We’ve been highlighting for several days now the significant chance that tomorrow’s storm tracks too far south to deliver much snow to the area, and as of this afternoon that continues to be the case. The models have mostly now locked in on a storm track that would give the D.C. area 1-2” inches of wet snow at most, with no snow (or at least no accumulating snow) a possibility as well, especially from D.C. to the north.

Sunday snow chances take a hit

All day long, model guidance has been trending drier and less snowy for Sunday. As icing on the cake, the NAM model - which had been the “snowy” model - simulated no snow for D.C. in its latest run this evening.

Inside a nearly impossible winter weather forecast

Last night, the models seemed to converging towards a snowy solution. It looked like there was a decent chance of meeting winter storm watch criteria. However, today’s runs paint a different picture as there continues to be model chaos. Even the question of precipitation type has not been completely resolved. The overriding unresolved question is how much snow will the storm produce and if it does now how much will stick. Both these questions are very much up in the air as very small changes in the storm track can make huge differences in the amount of precipitation it produces.

Sunday snow situation: could be boom or bust

During the day yesterday and last night, it looked like models were coming to consensus that we would get significant precipitation Sunday, and at least some of it in the form of snow. Now, it’s not as clear. As the impressive southern storm moves from the western Gulf of Mexico to the North Carolina coast, precipitation will have a sharp northern cutoff. Whether that cutoff is in D.C. area or southern Pennsylvania will make all the difference with respect to the kind of weather conditions we experience Sunday.

Accurately measuring snow: a critical winter weather challenge

Let’s assume there will be measurable snow on the ground by Monday morning. How do we most reliably figure out “how much?”. The answer to the question is not as straight forward as one might think.

Update: Sunday storm shows increasing snow potential

The models coming in this evening, thus far, have trended colder - which is critical for Sunday’s snow prospects. And while some earlier model runs showed the storm just grazing us, according to this evening’s runs, it now delivers a pretty good blow. So it looks like the necessary moisture and cold air may be coming together for accumulating snow Sunday. But - with the storm still 60-70 hours away - significant fluctuations to the forecast are possible.

President’s Day weekend: To storm or not to storm? To snow or not to snow?

The potential exists for a major East Coast storm this weekend, but it’s just as likely the storm passes to our south, harmlessly out to sea. Even if we get a storm, it’s not clear if precipitation would take the form of snow, rain, or some sloppy combination. In other words, right now we have more questions than answer.

Another iffy snow threat in the offing

Yesterday several computer models suggested there was a chance of a snowstorm Sunday. Now, several of them are backing away from that idea. The most we can now say about this weekend is there is a chance of rain or snow, but it’s even more likely the entire system stays far enough to our south that we remain dry.

Sudden graupel and squall Saturday afternoon (PHOTOS AND VIDEOS)

You have heard of graupel, right? If it’s not a snowflake, it’s not hail, it’s not sleet, it’s not snow pellets, but it’s white and falls from the sky, then there is a good chance it is graupel. On Saturday afternoon, a squall moved through Manassas, Virginia that produced graupel during its onset.

Are we done with winter weather? Or does weekend snowstorm loom? (POLL)

For about 36 hours, between sunset Saturday and sunrise this morning, it actually looked and felt like winter. We had wind, cold, and even a dusting of the white stuff. But this afternoon, we’ve warmed back up to almost 50 degrees. It’s tempting to say winter is over, but a number of computer models are hinting: hold your horses...

Rain/snow mix tonight, gusty snow showers possible late Saturday

Two rounds of wintry weather will visit the region in the next 36 hours. The first, tonight, should be mostly light rain but may put down a little snow in the far northwest suburbs. The second, Saturday afternoon and evening, offers the chance of rain showers changing over to snow showers as temperatures rapidly fall, possibly creating pockets of slick travel Saturday evening.

Key points for today’s snow and rain event

Today’s snow event is a minor one and may even be more rain than snow south and east of the District. Nonetheless, the coincidence of the storm’s heaviest precipitation with the afternoon commute may cause some slow going, especially in the colder north and west suburbs.

Steadiest snow may coincide with Wednesday PM commute

Based on this evening’s model runs, our forecast for Wednesday’s snow event is on track. The most important point to emphasize is that the “worst” of this event now looks like it will come through during the afternoon and evening rush hour.

Light snow likely Wednesday afternoon; could impact PM commute

A weak area of low pressure will drift through the metro region Wednesday afternoon, producing a period of light snow. Temperatures in the immediate metro region will tend to be above freezing, limiting accumulation to primarily grassy areas. The farther north and west you go, the colder it will be, and thus, the more predicted accumulation.

Snowmageddon from space two years ago

Two years ago, Snowmageddon, one of the D.C. area’s biggest snowstorms on record, finally came to a close in the late afternoon. That was after dumping a mind boggling 18-32” of snow over the course of about 30 hours. The storm shut the city down for days and is etched in the memories of all those who lived through it.

Light rain and snow to taper off overnight

Remnants of the winter storm that buried the Denver area Thursday night into Friday night are headed toward D.C. The storm, however, is a weaker version of its original self. That combined with recent mild temperatures means much of the precipitation we see will be on the light side and in the form of rain to start. Rain changes to snow north and west of the District, with light accumulations possible, mainly on grassy areas.

Super Bowl Sunday snow: it’s possible, but probably not consequential

We’ve been watching for several days now the potential for wintry precipitation this weekend. The responsible storm system is on its way to breaking a single storm snowfall record for February around Denver (9” already) but will weaken by the time it reaches the mid-Atlantic. Not to mention, there will be much less cold air to work with.

Big snowstorm targets Denver and central Plains, could it reach Washington, D.C.?

A major winter storm is forecast to blast both Denver and Boulder, Colorado with 10 to 20 inches of snow through Friday. Over the weekend, the storm is forecast to weaken, but some of its remnant moisture may stream into the D.C. metro region. Enough cold air may be in place for the chance of a little snow Saturday night.

A change to colder next week: pattern to improve for getting snow

Last week, it looked like February might end up a lot like December and January: warmer than normal, with below average snow. But new data have prompted Wes to revise this outlook a bit colder and snowier. He is now calling for near normal temperatures and snowfall during February.

Exactly one year ago, a powerful winter storm walloped the region at just the wrong time, leading to one of Washington, D.C.’s worst ever evening commutes. A thunderstorm of sleet and then snow overwhelmed the region between 4 and 10 p.m., paralyzing traffic everywhere. Chances are good either you or someone you know waited until it was too late to leave your/their job, and got stuck on area roads for hours.

Still near or below freezing most spots, but precipitation pulling away; remain cautious if out

Round two of this winter event has largely managed to skirt the immediate D.C. area to the north and to the south. Still, freezing drizzle has led to additional iciness even in places that have not seen sustained freezing rain this morning. Ice accumulation on top of snow and sleet appears to mainly be about a trace to 0.10” locally, with more north and west. Temperatures that are slowly rising are still near or below freezing across most of the area, though they should rise a few degrees heading into or during the afternoon.

Heavy rain to likely end as snow Wednesday night; sloppy accumulations far N & W suburbs possible

The snow threat remains for Wednesday night but, for most of the region, the event will probably be a minor one.

Wednesday night snow potential: other view points

Meteorologists and media outlets have been posting their thoughts on Wednesday night’s snow potential, so I thought I’d pull them together and offer some commentary.

AccuWeather, WeatherBug, ABC7 update winter outlooks

Capital Weather Gang released its winter outlook in early November, and Thursday winter weather expert Wes Junker updated our outlook for December. In short, for the winter we’re predicting near to slightly below normal snowfall and near normal temperatures. Over the last few days, several other outlets have tweaked their outlooks, which more or less continue to be consistent with our outlook predictions.

The Siberia to East Coast snow connection

In Tuesday’s Washington Post print edition, CWG’s Andrew Freedman profiles the work of Judah Cohen, Ph.D., principal scientist at Atmospheric and Environmental Research (a Verisk Analytics company) who has studied linkages between fall Eurasian snow cover and East Coast winter weather. The article begins: According to new research, Washingtonians shouldn’t blame bad luck for the recent string of high-impact snowstorms, from “Snowmaggedon” two years ago to last January’s “Commuteageddon.” Instead, it may be more justified to cast a suspicious gaze toward Siberia, about 6,000 miles away.

Why are snowstorm forecasts sometimes so wrong? Part two

Last week, I discussed several of the challenges in making a snowstorm forecast. They include: 1) many of the physical processes that govern the atmosphere act non-linearly, 2) uncertainty about the initial state of the atmosphere, 3) certain part of a model’s physics have to be approximateds. Today, I’ll walk you through the additional three factors which can lead to bad forecasts

Why are snowstorm forecasts sometimes so wrong? Part one

Almost every year, at least one snow forecast ends up busting in our region. Many readers probably remember last year’s December 26 bust (when we called for 3-6” of snow, and little fell). The fall-out elicited remarks like “weather forecasting is the only job where you can be wrong 90 percent of the time and still keep your job.” While that’s a huge overstatement about the state of weather forecasting, it certainly captures the frustration that many feel when a forecast fails. This article will attempt to explain why the forecasting a snowstorm is so difficult and why meteorologists often equivocate when discussing a storm’s potential. This is part one in a two part series.

Washington D.C. winter weather forecast 2011-2012: average temperatures, more snow than last winter

For snow lovers hoping for a repeat of the epic 2009-10 winter, you will probably be disappointed.  This winter is much more likely to be similar to last winter, when 10.1” fell, than the record-setting 56.1” of 2009-10.  But we don’t imagine this winter will be a dud either. It’s unlikely to be as cold as last winter, but we are not favoring a warm winter either.  Furthermore, we have a good chance of matching or exceeding the snow totals of last winter at all three airports.

Do October and November snow signal a snowy winter?

OK, so we had some snow in parts of our area last month (just a trace at Reagan National and .6 of an inch at Dulles), now that it’s November, we could have some more. Time will tell. (I don’t do the forecasting on this blog.) But what does October snow mean, if anything, for the rest of the winter as a whole? Curiosity got the best of me and, although it’s been done many times before, I decided to do some of my own research.

How well did we predict Snowtober?

When we planned the release of our winter outlook for the first week of November, little did we know the season’s first winter storm would occur before then! To sum up our forecasting performance for Snowtober (October 29), we were overly skeptical of a snow event prior to two days before the storm struck, but did a very good job of forecasting the storm within 48 hours.

Global warming and extreme weather: Northeast heavy precipitation spiking in winter

Was the weekend’s “epic” storm in the Northeast part of a long-term trend? It’s certainly not inconsistent with the region’s experience in recent years. Data from the National Climatic Data Center indicate heavy cold season (October to March) precipitation events are intensifying.

Readers, Capital Weather Watchers document rare October snow

Who knew the first opportunity to enlist our readers and newly minted Capital Weather Watchers to document the season’s first snowfall would come before Halloween? Throughout the storm, we received a constant stream of reports as well as multimedia to ground truth what was happening throughout the region. Thanks to these reports, we were able to keep everyone informed about who was getting rain, sleet, and snow, and how much. Suffice to say, our community of readers provided in­cred­ibly useful, entertaining, and visually stunning content. Thanks so much! And enjoy the imagery in this post!

Historic October Northeast storm: Epic. Incredible. Downright ridiculous.

Epic. Incredible. Downright ridiculous. These words best describe the historic snowstorm that delivered a crippling wallop to parts of the mid-Atlantic and Northeast over the weekend. Widely referred to by its social media moniker, “Snowtober,” the storm smashed records that had stood since the beginning of the reliable instrument record in the late 1800s (and in some cases, even longer than that), and upended assumptions about what a fall nor’easter can do. The heavy, wet snow pasted onto trees still bearing foliage in many areas, weighed down power lines and caused more than three million power outages.

Rare October snow tapers; freeze tonight

Snow and mixed precipitation have largely tapered off across the region. Temperatures tonight will get quite cold, ranging from the mid-20s in some the coldest suburbs to the low 30s downtown - ending the growing season across much of the region. Sunday is sunny but brisk, with highs only 45-50.

Rare October snow likely for D.C.’s north and west suburbs

A rapidly developing, intense East Coast storm will bring unseasonably cold temperatures and heavy precipitation to the entire metro region Friday night and Saturday. For the immediate metro region, rain is likely to be the predominant precipitation type, but snow may begin to mix with the rain late Saturday morning and possibly change to snow briefly during the afternoon. Accumulation is unlikely but cannot be ruled out. Towards western Montgomery, Frederick and Loudoun counties, a changeover to snow is more likely to occur and occur earlier, with the potential for some accumulation, especially at higher elevations.

The low odds, high impact October snow scenario

I debated even posting this, but if I have information, why hide it? The latest North American Model (NAM) pastes the D.C. metro region with an unprecendented late October snow event. Ready for this? It simulates 4-8” of heavy, wet snow Saturday. Caution: this model has been wildly inconsistent and had the storm out to sea as of this morning, so take it with a huge grain of salt.

Saturday storm analysis: will cold rain change to snow?

The odds of a highly unusual, though not unheard of, period of October snow have increased for northern and western parts of the D.C. region on Saturday. Yesterday, Jason outlined what ingredients were needed to get accumulating snow in the Washington area during October . The majority of computer models are now showing more of those ingredients than yesterday.

Saturday snow chance remains longshot; freezing temperatures possible Saturday night

The latest computer models continue to suggest the odds of seeing snow Saturday morning in the Washington metro region are small, but not non-existent especially in outlying western areas. A cold, light rain remains the most likely scenario and it’s still possible much of the precipitation misses to our east, and it’s dry. Perhaps of greater significance, many locations may experience their first freeze Saturday night.

How likely is snow Saturday in the D.C. metro region?

Over the past couple of days, the European weather model (ECMWF) has been advertising the potential for snow in the Washington area Saturday, especially for areas west of the city with elevation. As Ian Livingston noted , accumulating snow is extremely rare in Washington during October. It has only been recorded five times in a total of 4,340 days. Because of its rarity, any model forecast of snow should be looked at with some skepticism, especially when the forecast is a projection that is four days from now.

From frigid conditions in the northern tier of the U.S. to very wet and stormy conditions in the East, it predicts the upcoming winter will be an “unusually” tough one. But should we put much stock in this outlook? I’d say just a very little, and will explain.

Image of day: Sunday snow summary

We’ve been talking about the chance of snow Sunday since Tuesday, but just today started to talk about amounts. Generally speaking, we’re thinking a dusting to an inch is the best bet. However, some of the model data and NOAA assessments indicate more is possible. So I thought I’d share them so everyone can understand the full suite of possibilities.

The GFS model (run this afternoon) indicates very light snow Christmas afternoon and evening with the modest storm mostly going out to sea. The European model (run this morning) simulates the same system as a full-fledged blizzard Sunday into Monday.

D.C. record snow in 2010 not due to global warming

A new study by a team of scientists at Columbia University's Lamont-Doherty Earth Observatory argues that global warming was not involved. Rather, the study finds the anomalous winter was primarily the result of convergence of an exceptionally strong El Nino and unusually strong negative phase of North Atlantic Oscillation (NAO).
