yoda Posted December 26, 2010 Share Posted December 26, 2010 Can you post the image? I cannot get it yet on Raleigh's site. I used the 72 hr total precip map since the 48 one wasn't working... but give me a min Link to comment Share on other sites More sharing options...
real Posted December 26, 2010 Share Posted December 26, 2010 It is painful watching local radar- almost looks a like a snow shield is cover the beltway- is that the NW wind pushing everything away for now? FWIW: I checked this a little more than 15 minutes ago (when I went out to look for flurries lol) and it was stopped at Beltway in PG County to east. Now, its at least over half of DC.. The northwest push is one. http://www.accuweather.com/us/radar/sir/dca/radar.asp Link to comment Share on other sites More sharing options...
Dr No Posted December 26, 2010 Share Posted December 26, 2010 How far off the coast does the ruc show it when it is in the Hatteras-va beach vicinity? At hr 11 it bombs the 850 low over Hatteras (with the surface low just SE)... the Low probably will not move much more east of that longitude on this run.

PhineasC Posted December 26, 2010 Share Posted December 26, 2010 I used the 72 hr total precip map since the 48 one wasn't working... but give me a min I guess you zoomed in or whatever, but DC looks almost in the blue on the 72HR map. Link to comment Share on other sites More sharing options...

Nor Easter Posted December 26, 2010 Share Posted December 26, 2010 http://forecast.weather.gov/MapClick.php?site=jax&zmx=1&zmy=1&map.x=224&map.y=145 Down to 1002.9(lowest I could find). South wind suggest the low still hasent passed the reporting station. Radar showing precip really starting to explode north into NC. SREF's show low stalling close to MD coast may not be too far off, seems as if the low is bombing out faster. The faster it bombs, the farther west it goes and faster it will occlude. -Nor Link to comment Share on other sites More sharing options...

MD Snow Posted December 26, 2010 Share Posted December 26, 2010 I am a total amateur but radar along the Georgia coast means some serious business.

Dr No Posted December 26, 2010 Share Posted December 26, 2010 You wouldn't want to be on the eastern shore or coastal NJ/NY that run. It's so wound up it would probably change them over with a LLJ that strong at 850 MB from the SE. Link to comment Share on other sites More sharing options...
real Posted December 26, 2010 Share Posted December 26, 2010 yea, looking at that Jacksonville and regional radar, this is either going to be a respectable snow (expecially considering everything this week) or one hell of a miss. I vote for the former Link to comment Share on other sites More sharing options...
weathercoins Posted December 26, 2010 Share Posted December 26, 2010 Is it just me or are the chances of a super pleasant surprise going up, between the low pressure and the new clown models?? Link to comment Share on other sites More sharing options...
Stormpc Posted December 26, 2010 Share Posted December 26, 2010 Light-Mod snow here now......Amazing how the northern edge keeps getting squashed over NOVA. I know this is not the time period where we get our "good snow", but a nice pre game, a-la-Richmond, makes things look better. SC upstate looks promising, but really progressive for us in DC area, Link to comment Share on other sites More sharing options...

It means the GFS and NAM aren't seeing the depth of this low. Might lead more credence to SREFs being closer in. These small changes mean little up north, but can definitely affect us.
