Forecast: Some snow showers today. Flurry Sat?

By Camden Walker

Sunday may see fair conditions; snow next week?

EXPRESS FORECAST

Today: Periods of snow showers. Mid-to-upper 30s. | Tonight: Clearing skies. Low-to-mid 20s. | Tomorrow: Increasing clouds. Flurry possible late. Mid-30s to near 40. | Sunday: Partly sunny & milder. Near 40. | A Look Ahead | Get Express Forecast by E-mail

FORECAST IN DETAIL

The pattern of late, continues: somewhat chilly days with the potential to see a few flakes here and there. We could see a new snow coating today with a fast-moving clipper system passing by, and again some flurries or brief snow showers late tomorrow as another passes to our north. Sunday is our day to get outside a bit. Why? Because by early next week we ONCE AGAIN have a winter storm threat to keep an eye on...

Snow Potential Index: 5 (↑) - Flurries early become snow showers (mixed rain?) through midday. Slight flurry threat Sat., more next week?

 
The SPI is a daily assessment of the potential for accumulating snow for the next week on a 0-10 scale. Get the 'SPI' on Twitter
 

Today (Friday): The best chance (60-70%) for snow showers (mixed with rain D.C. and southeast?) is around midday today, but the flurries and/or moderate showers could intersperse themselves 'til afternoon. By region, early-to-mid morning flakes (west) to early-to-mid afternoon flakes (east/south). Temperatures still manage to get into the mid-to-upper 30s with the help of some off & on sunshine that filters through the clouds. Accumulations shouldn't be too troublesome -- a coating to 1/2" inch seems possible. Breezes should be pretty light & variable -- barely perceptible for most of the day.Confidence: Medium

Tonight: Slowly clearing skies and light northwest breezes create a fairly chilled evening and overnight. Lows should end up in the 20s, metro area-wide. Mid-20s downtown, with around 20 in the colder spots near the Blue Ridge (you know who you are!). So, bundle up with those scarves and boots, as another re-freeze happens tonight with leftover slush. Confidence: Medium

Another winter storm possible? Seriously? Keep reading...

Tomorrow (Saturday): Largely or wholly dry but with a risk of yet another flurry during the latter part. But much less chance this time overall. Highs should head into the mid-to-upper 30s -- perhaps even 40 or above south and east of town -- assuming we see some breaks in morning clouds by mid-afternoon. Breezes should stay light, out of the southwest. Confidence: Medium

Tomorrow night: It's again somewhat chilly, in the 20s. But I think we are mostly acclimated & used to it, right? Almost a repeat from last night, mid-20s appear probable downtown, with closer to 20 once you get far away from the Beltway. Confidence: Medium-High

Sunday: Part of me wants to joke that today is the "day to pickup your abandoned vehicle from Wednesday night." Sun breaks out, winning out over the clouds, as high temperatures strike the 40 degree mark in most spots. Get out and enjoy or do those errands you have been putting off. I certainly have limited my travels around town, while there is so much slop around. Confidence: Medium

A LOOK AHEAD

On Sunday night another Arctic high pressure system really begins to influence our region. Temperatures quickly fall off to mid-teens in the suburbs and around the low 20s downtown. Only a few clouds around, though. Confidence: Low-Medium

Monday begins another examination of possible incoming wintry weather during the week. Clouds should be on the increase, but with some sunshine to be enjoyed in the morning hours with any luck. High temperatures are probably above the freezing mark in the mid-to-upper 30s. By the evening or overnight, there is a slight 10-20% chance (as of now) for a few flakes. Timing is still a question mark. Confidence: Low-Medium

Tuesday is tricky like last week, but that storm ended up waiting until Wednesday and the bulk of this one might as well. Either way it's pretty cloudy and we do start seeing the chance of snow or a wintry mix (potentially including rain). If the storm ends up far enough west it could even be mainly rain. With a 30-40% chance of precip during the day and increasing late, high temperatures may only make it into the mid-30s, perhaps nearer 40 if precip fully holds off. Confidence: Low

Question - we heard the thundersnow and saw clod to cloud flases. Does thundersnow have cloud to ground lightening and if not, why?

Hi -- I asked this question yesterday and it may have been overlooked.

Why did New York get 16 inches of snow and we got about half that? I thought with New York being closer to the ocean they would have had more warm air pulled into the storm? That would've meant more rain and less snow. Did the storm deepen that much more as it moved up the coast to give them that much more snow?

Thanks!

Flurries in Laytonsville this morning.

Thunder-Slop was a very interesting storm. We ended up with some wicked wind-driven snow forms. Tallest drift measured 2 and 1/2 feet tall. Nothing like the 6 foot drifts from last year, but impressive nonetheless.

@biketraveler22

To my knowledge, thundersnow is physically no different than normal thunder. It will reach the ground, given the chance. The only real difference between lightning and thundersnow is the temperature. Which is why it's so special. :)

To get lightning in general, you typically need a cumulonimbus cloud. These clouds can't exists without enough instability in the atmosphere. To get this instability, temperatures at lower altitudes need to be *relatively* warm enough to begin to rise into the atmosphere. It's all about creating enough difference in temperature.

The thing is, to get thundersnow that warmer air can't be above 32 degrees at any level or you'll have plain ol lightning sans snow. That's ok though. As long as we have our temperature difference. What I think happened in this latest storm was we had just enough warmer air mixing in from the south that provided enough instability in the atmosphere without (in most places) raising the temperatures too much. And voila! Thundersnow.

Does that sound about right to anyone else? I just mostly reasoned that in my head. :)

NYC had some over-running snow at the outset and the Low bombed out to their South and East. That means the flow was from the north pole as it passed by, not the Atlantic for NYC.

Not sure there is a point in naming the storm anything other than "Carmageddon", since that is all I hear everywhere.

The storm for next week is all over the "maps". Some have it cutting to
the lakes but giving us a few inches of snow from the front running precip.

Some have it heading to Pittsburgh before transferring energy to a coastal storm while giving us the entire range of precipitation types.

The DGEX has split the storm into two parts, the first piece coming through with some rain but with a second piece of energy heading up the coast as a MAJOR snowstorm for the area on Friday.

Who to trust...

CWG- quick! Make your prediction right now, and I SWEAR I won't hold you to it ;)

For those who wondered why so few people listed to this week's weather report for the Thursday storm, one of the problems has been the weather forecasters (including the WaPo's weather team) who make all the false alarms about weather that never comes. Just like they did one month ago - going from predicting 10 inches to a dusting while jerking everyone around traveling back the day after Christmas. But you will notice the WaPo in its editorial blaming everyone else on Thursday night conveniently forgets something from only one month ago. This is what the crying wolf syndrome does to the public's confidence.

Posted by: responsiblepublic | January 28, 2011 7:45 AM | Report abuse

Do people really significantly change their travel plans because they feel in danger based on weather forecasts?? This just dumbfounds me. I really can only understand making changes if they're along the lines of rescheduling beach vacations or trips to the Bahamas because of rain forecasts.

What's the big deal? If you think the weather forecast will get flights canceled, there's no action you can really take until you hear that your flight has been canceled. If you're afraid that heavy thunderstorms (or snows) will make it dangerous to drive, do you really need to change your plans significantly?? Can't you just leave a little later, after it storms or snows? I left the house for wine after the snow, around 10 PM, so the weather forecasts didn't destroy my life - they just delayed my trip by a few hours. Really, it wasn't the forecast so much as me seeing the snow stop that let me know it was OK to go driving.

Am I alone in these thoughts? Is everyone out there who's upset right that we live and die (or at least sit in traffic jams) by the weather forecasts?

IMHO, if the public's confidence is hurt, it needs to look at the man in the mirror. ;)

I am wondering why on "The New WAPO Website" up at the top of the page is indicating no snow today but yet at the side of the page it is indicated as 60%? I noticed yest. it had a 20% on the "website" page and 60% on the sidebar, but didn't want to interrupt the Name the Snowstorm thread.

And I vote strongly for a Droid app. I can get the WAPO app but can't get CWG unless I go to the www.washingtonpost.com and that takes time.

Finally, well done folks. I have been interested in weather for awhile and you and the other readers humble me. So knowledgeable and informative. Thank you for helping us "wannabes".

Light snow has begun in Metro Center

biketraveller22 - and others. The lightning (bolt vs. sheet, between clouds) deserves a bit more research on my part. But it sounds like there could have been a bolt or two that struck the ground. What is a notable dynamic difference with winter vs. summer lightning is that surface air is not heated and convecting upwards into the clouds, which would promote charge differences between surface & cloud base (step one to getting a bolt of lightning which would serve to balance the charge)

@amerikajin777 - I'm so jealous! I sit on the first floor nowhere near a window so I can't enjoy the snow like you can.

About all the power outages -- yes, those sucked. We only lost ours for just shy of 24 hours but that was enough time to realize how dependent on electricity we've all become - we're quite the opposite of the Electricity-Avoiding Amish! Still, the power being knocked out gave us great occasion to enjoy wine and some fine conversation together :)

This question of course isn't for CWG but I wonder why we get so many power outages in the DC area?? Are these as common in other parts of the country that get lots of snow regularly? Or are/were they just as common in parts of the country that don't regularly get snow but got thwacked this winter, like our friends down South did just a few weeks ago? Or are our frequent outages a reflection of the fact that so many people live in the suburbs and exurbs around here?

...Maybe all of the above has no relation to why our power gets knocked out so frequently, and Pepco is just a poorly run company!

I think it'd be nice if we could get to the root of this problem, though, because I think that we all agree that the thunderstorms and minor snow/ice storms that this region gets shouldn't put so many households in the dark!

kolya02 - the snow quality was exceptionally heavy and wet this week. It fell in also a very--virtually record breaking--pace in such a short time. Recent winters haven't had these conditions (dryer snow was typical last year; winds weren't much of an issue either) -- Trees fell in great numbers and snagged many power lines. It was, in a way, overdue from a statistical standpoint. A very unfortunate situation. Nature has pruned the trees in a way, which should curtail the magnitude with which we had these problems (trees onto power lines) for a good period moving forward. I am a fan of my buried power lines downtown. Oh yes.

FIREDRAGON47 - sorry to hear about all the damage. Most unfortunate. Hope everyone is ok, at least. Keep us posted on accumulation today there were you are--temperatures are marginal and may rise after the precip is done (next hour or so, approximately)

celt1 - melting sounds about as expected. Doubt many, if any, will get over an inch today.

Anyone have over a half inch? Keep us posted. I do expect temperatures to aid in melting later this afternoon, after precip stops. The coating might not last long...

Thanks for the reply, Camden, and for putting in context how historically strong it was. I guess I'm having trouble with how often 'treacherous,' 'deadly,' and other hyperbolic terms are tossed around to describe our winter weather events. KRUZ and others were on here the other day describing the event as awful and deadly as though it were a blizzard! I'd understand the school closings and other hype if the DC area just reacted to winter weather this way - it is, after all, something we don't usually get much of. But we can't handle hot humid summer weather either! I'm beginning to think that ex-Philadelphia mayor was on to something when he said that we've become a nation of wusses!

Snow is slowing in Manassas & skies are brighter. It looks as if we might have close to an inch of new flakeage.
This would have sent us all into spasms of delight or consternation just a few days ago. After being thumped everyone is numbed to the excitement.

Snowed hard here in Leesburg for about an hour, but didn't seem to accumulate to anything. Maybe a bit in the shadiest spots.

Sure looked pretty, though!

Regarding hyperbolic comments about this storm, my thoughts are mostly aligned with kolya. While at least one person died directly from the storm and others during storm clean-up, it's quite possible that a fatal traffic accident or two were avoided because of the storm (due to more people staying home, both Wednesday and Thursday). The media tends to hype up isolated deaths during storms. It's similar to shark death panics, really.

What is undeniable about this particular storm is its catastrophic effect on traffic and that it caused uncommonly high power outages.

The snow has been pretty steady for over an hour here in Silver Spring. I hope it tapers off soon.

DGJung, any accum in Silver Spring?

Walter, yup, very low. It was quite a work by the atmosphere though.. wellll over an inch of rain, had it been all above-freezing in the atmospheric column between cloud & ground!

FIREDRAGON47 - wow almost an inch? We have nothing, dusting that has melted, here in Metro Center. Sounds similar to AsymptoticUnlimited who reported from Leesburg...

kolya02 & AsymptoticUnlimited - I like discussing the topic you bring up. Weather communications is very important to me, and to CWG teammates--all of us. That is why we are here. I agree it was a very bad situation. Power outtages and traffic were, well, about as bad as they get in DC--in such a short time. Snowfall rates of 1.5-3.5" PER HOUR are ALSO stunning to virtually ANYONE in the nation. Those snowfall rates are more common in the narrow snowbands within Lake Effect snow regions in the northern tier states. It was a unique, powerful set of ingredients. My goal was to measuredly and deliberately communicate (as best possible in the admittedly chaotic situation after the snow started) what to expect. I want DC residents to be informed and to make their own decisions. To care for life, limb, & property. I wish more folks had stayed home on Wednesday, perhaps. But I feel few believed the intensity, over a few-hour period, that we at CWG were calling for. Ok, enough with my mission statement. But glad you all think about how DC reacts to these things-- I always want to mitigate the impacts we saw on Wednesday night though :)

The snow accumulated to about 1/4 inch on tree branches outside my office window in downtown DC but it's all gone now. The heaviest snowfall rate I've ever seen was 4 inches in 45 minutes in DC in March 1984, including continuous thunder and lightning. It was totally amazing, I could barely see across the street.

I read somewhere once that the theory of lightning depends on charged water droplets and doesn't work (theoretically of course) for snow? True?

Camden - Maybe not quite an inch, but enough to semi-disguise the grotesque gray roadside snowbanks.
