A weak low pressure along a frontal boundary will spread light snow across the Middle Atlantic with light amounts in the 1-4in for many areas especially in southern Pennsylvania and northern Maryland.

February 8 Middle Atlantic Light Snow Event Timeline and Discussion...
A weak low pressure will move along a stationary front across northern Virginia during the day Wednesday. An enhanced jet and increasing southerly flow will advect a bit of moisture around 700mb enhancing a light area of precipitation from West Virginia up through southern Pennsylvania. This area will primarily be driven by isentropic lift maintaining light to moderate precipitation rates. Cold air advection originating out of Ontario will continue to funnel south through the Northeast on Tuesday setting the stage for a light snow event on Wednesday as precipitation enters the Middle Atlantic. The current track of the primary vortex of energy will be across northern Virginia. This track is favorable to spread the heaviest QPF 50-100mi north of the vort using the typical rule of thumb. QPF totals will range from .1-.25in for most areas with the highest amounts on either side of the Mason-Dixon line within 25mi. PWATs will increase to near .5in during the day Wednesday as moisture begins to funnel through the entire atmospheric column. Dry air will battle the northern edges of the shield of precipitation particularily towards I-80. Surface temperatures will be in the lower to mid 30s across central and northern Maryland to around 30-32F for southern Pennsylvania. This will limit snowfall especially given antecedent mild temperatures. Snowfall will generally occur in grassy locations especially for Maryland.

Temperatures in the mid 30s towards Washington DC will set up the battleground across this region for rain vs. snow. Temperatures through 950mb will be below freezing, but the warm bounday layer temperatures will allow for the mix. If the vort travels a bit farther south than expected an area of enhanced moisture may occur across the capital district with bursts of moderate snow, but at this time this looks unlikely. Still the city and surrounding suburbs may see up to 1in of snow. The highest QPF and coldest surface temperatures will favor the highest accumulations across extreme southern Pennsylvania into Somerset, Bedford, Fulton, and Franklin counties. I cannot rule out a spotty 5in or 6in amount across the Mt. Laurel/Davis area. Elsewhere in those counties 2-4in amounts are more likely especially above 1000ft.

Spotty 2-4in amounts are also possible across the high ground (above 600ft) in far northern Maryland.

9am-12pm Wednesday- Light snow will begin to across western and central Maryland/Pennsylvania/Virginia. Temeperatures will slowly fall below freezing for areas near the Mason-Dixon line given initial low dew point values. Elsewhere temperatures will also fall, but hover around 34-36F towards Washington DC. Snow accumulations will be limited to 1-2in generally across western Maryland and the Laurel Highlands.

12pm-4pm Wednesday- This time period will feature the primary event with light to occasionaly moderate snow occuring. Visibilities will generally range from 1-3mi during this period with brief TAF IFR conditions possible. Accumulations in this period will be around 1-3in for most areas.

4pm-6pm Wednesday- Precipitation will change to light snow as far south as Washington DC before ending for eastern areas also. Additional accumulations will be 1in or less for all areas.

6pm-8pm Wednesday- Downsloping and waning isentropic lift will weaken the precipitation shield for extreme eastern Pennsylvania, Delaware, and New Jersey. By 8pm all precipitation should be over across the Middle Atlantic.

Regional Advisories...

This is my current rain/snow line...
Warrenton, VA - Washington DC - Annapolis, MD - Dover, DE - Vineland, NJ

***Areas north of this line will feature a mostly snow event with the region 25mi either south/north of this line featuring a rain/snow mix. Even areas along the line may see a very light accumulation of snow. Given the upper level thermal profile, there will likely be no mixed precipitation and either a rain or snow event.

Storm Reports...
None.

Storm Impacts...
1. Light snow accumulations of 1-4in for most areas.
2. Snow will falling during the daylight areas including the evening commute with travel impacts likely.
3. High snow accumulations will be along the southern Pennsylvania border counties particularily in the Laurel Highlands.
4. Snow will fall across a region that has not been exposed to much winter weather weather this season.
5. Most of the accumulating snow will end by 8pm for all areas.

Snow Maps...


***There will likely be a few spotty coatings to 1in amounts just north of the 1-4in region, but virga should reduce amounts along and north of I-80 to near nothing. The highest amounts will be across the Laurel Highlands and Garret County, Maryland with a few isolated 5-6in amounts possible in the favored upslope regions.

Model Analysis
Model guidance is in general agreement for this weak surface wave, but a few differences arise especially for boundary layer thermals across the Washington DC area. The ECMWF remains a bit warmer than other guidance, but I tend to find it runs a tad too warm. This was certainly exhibited last Saturday with the light snow event across the Middle Atlantic. General SREF/NAM/ECMWF/GFS QPF is in the .1-.25in range for most areas with a northern cutoff around I-80. The track of the vort will be critical for areas in the rain/snow area, but most models have generally agreed on a similar track. In the longer range, models indicate colder air plunging across the Northeast this weekend although nothing out of the ordinary for early February standards. GFS and ECMWF argue for a few potential snow squalls along the arctic front, but this remains a low probability especially east of the Alleghany Front. After a 4-5 day cooler period, warmer temperatures are likely to move back in across the Northeast with a zonal Pacific flow in control with limited precipitation events.

After the Storm
The next two week period looks to feature well above normal temperatures with well below normal precipitation; therefore the likelihood of snowfall is below climatological averages. The MJO will continue to rotate through phases 6-8 over the next two weeks with strong forcing. Composites indicate a mild pattern from this regime over the Northeast. The arctic oscillation is actually anomalously low (near the record low values of 2010) which is quite coincidental given the record high values back in December. But the other teleconnections are not in favor to send this arctic air across North America especially given the swirling Alaskan Vortex. Much of this cold air has been focused across Europe into parts of Siberia. Model prognostics indicate a dominate 1060hPa anticyclone (models will verify too high for pressure) over Siberia. Arctic air will flood this region of the world over the next two weeks, while North America is sitting under a zonal Pacific regime. Very few perturbations in the jet will characterize a very dry period over the next two weeks. This is supported by recent global model runs indicating less than .4in for most of the Northeast over a 16 day period.

Any potential for snow will remain slim. A few ensemble runs have noted the February 10-12 period as of particular interest, but the placement of the polar and subtropical jet do not appear favorable. While there will be occasional cold fronts with 1-2 day periods of cooler weather, the overall pattern is mild with many days running 5-10F above normal. I cannot rule out an unexpected snow threat, but it is likely this will appear at the last minute on guidance if it should occur. Given the end of the Nina flow, chaos has consumed most model guidance especially post 3 days. Therefore any model output should be taken with a grain of salt. If one can get past operational and ensemble model output, the overall pattern is similar to that of much of this winter.

Please post storm reports in this blog from across the Northeast during the winter storm and please post location of observation in each report...

Hey Bliz if these model trends continue to develop the storm faster this could actually be quite a big one here in Southern New England what do you think?

Hey Blizz I have a trivia question for you.

Since records have been kept, what year recorded the LOWEST, HIGHEST snow total for a single event? Lets use your hometown as the location.



If the question sounds confusing, what I mean is... Say your town just got 2.3 inches of snow. and at no point in this entire season you got more then that from a single storm, that would be your single storm high for the season. Has any other year had a lower "high" single storm snowfall amount?

Hmmm... I understand your question but I am not sure where I would be able to find that data. We can track down seasonal totals, but I do not think the NCDC breaks them down further by individual storm. I can answer for my own personal records, but they only go back since the winter of 2006-2007 or so.

NWS has increased our chance of snow for Saturday. It was showing 20% earlier this morning and I guess it as three-o'clock crew that has now brought it up to 30%. Heavy wind too. I knew those fields of robins were a portend.

So it seems, especially more so now with the last two comments on here. Looking forward to following a possible snow storm for the first time this year. But I won't get too excited yet, as it seems things have to come together rather perfectly.

CONFIDENCE INCREASING IN AT LEAST AN ADVISORY LEVEL SNOWFALL FRI
NIGHT-SAT ESPECIALLY FOR CT AND LONG ISLAND. LATEST NAM NOW HAS A
STRONGER SFC LOW PASSING OVER THE 40N/70W BENCHMARK AT 18Z SAT...
PRESUMABLY DUE TO A SLOWER AND MORE AMPLIFIED NRN STREAM TROUGH
ALOFT TO THE WEST THAT ALLOWS CYCLOGENESIS IN RESPONSE TO THE
APPROACHING SRN STREAM DISTURBANCE TO TAKE PLACE CLOSER TO THE
COAST AND CLOSER TO A BAROCLINIC ZONE OFF THE MID ATLC COAST.
IF THIS TREND APPEARS IN OTHER GUIDANCE AND/OR HOLDS WITH LATER
RUNS...WE COULD EVEN BE LOOKING AT A SIGNIFICANT SNOW FOR LONG
ISLAND AND MUCH OF SOUTHERN CT.

We are getting into mid-February where temperature fluctuations are higher. At least what I can recall from my experience.


Daily averages for coastal regions have begun their slow climb upward going back about a week or two.

Aside from this weekend we will continue to be a bit above normal with longer range outlooks calling for above normal into Spring.

Those don't always pan out and Spring can be a tricky thing to forecast long range especially at the coastlines.

Depending on what the wind flow is can be the difference between 50s and 70s right into June as the ocean remains cold into July in most seasons.

you missed out on the snow yesterday, huh?

The area looks so beautiful in white. You should see the trees. They look like they have 4-5 inches on them. It's a shame we only got 2" out of the storm.

Are you saying this might be a coastal storm? The past week I have noticed more activity in the Gulf. It's only a matter of time for that area to bring forth a storm.

Coming to and end here with flurries which will soon fade away. There's a bit of accumulation on the balcony and roof, perhaps two tenths of an inch.

Hola Hoy,
Nice to see you again.

We have had some wild robins partying in the neighborhoods. Whatever they are eating has served to paint the sidewalks with deep purplish-blue splotches. I associate mass Robins with a storm-a-coming, but sometimes they arrive a week before the weather.

Misty light snow went non-detected by most radars, finally cutoff at 8:30pm, 32F. This probably added another half inch or slightly more. Couldn't give an accurate total without a whiteboard.

Roads wet, sidewalks whitened, grass thickened white, snow plastered on all the trees. Very nice...

Looks like I am going to mark down 2.3in for back home; not too bad. Seems like once east of Linglestown accumulations really dropped off to less than 1in especially Lebanon county east. Also areas southeast of Valley Green in York County did not seem to get the expected accumulations. Very tricky storm with a lot of busts given temperatures. The main issue was the lack of higher snow rates even for areas that received rain. Highest totals are from the Laurel Highlands east to Carlisle or so. Better than nothing especially since pretty much only Pennsylvania saw snow totals over 1in from this event.

Getting a report from home of 3in, which I will check with them to be sure. Also a report of 2.5in in Harrisburg. Also a 3.0in report towards Summerdale, PA which is just on the other side of the river from Rockville. Appears like central Dauphin County did pretty well in this event from Dauphin, PA on southward to Middletown and west to about the Grantville-Hershey line.

Thanks guys for the answer. Up here in Stamford CT., just a few flurries, and looks like on radar the precip. is decaying, getting smaller in coverage, so I don't expect even a coating.

Still snowing here, but just wet roads. I see they've upped the percentage for snow chances here on Friday night and Saturday from 30 to 50...so that's something.

Looks to be about an inch of snow at my apartment just south of Camp Hill boro. Main roads weren't bad at all on the drive home but side streets and parking lots were definitely slick.

While the snow came down quite nicely from say 12-2pm after that it seemed to switch over to a much smaller flake if not a sleet/freezing rain around 4ish.

Quoting MariettaMoon:
Snow to rain ratios, not necessarily meaning water content of falling snow, but how much snow has been measured accumulated compared to total precip.

Through 5 to 5:15pm (Snow/Precip) = Snow:Rain Ratio

Williamsport PA: (0.5/0.07) = 7.1:1
Pittsburgh PA: (1.5/0.13) = 11.5:1
Harrisburg PA (KMDT): (1.3/.17) = 7.6:1

I have 1.0/0.13 = 7.7:1 which is pretty consistent with those numbers. I think this has been the wettest snow we've seen since October.

The snow stuck to trees and branches like glue which probably created some great photos today across the area.

LT: Hoy is right. In this case I accidentally hit "Quote" rather than "Modify" for my own comment & posted it. When I saw what I did, I erased & put nm (nevermind). You can't delete them.

Quoting originalLT:
MM, what does NM mean on post #102?


I believe he does that when he posts something (perhaps a graphic) which doesn't work. Modifies comment with NeverMind. I've done it before as well. There should be a way of deleting your own comments.

Came here to say it's snowing in Brooklyn (for the last 20 minutes), but Dabbio beat me to it.
