usedtobe Posted December 24, 2012 Share Posted December 24, 2012 The NAM is the least optimistic for those guys...even MRB goes to sleet by say hour 49.....The other models are colder...maybe MRB can get 1-2" and then sleet and then rain... Possible as we get into the shorter time ranges, the NAM's soundings start winning if they have the same track and intensity. I'm rooting for Ji, Leesburg and Co. to get a little love.

Mrs.J Posted December 24, 2012 Share Posted December 24, 2012 Ok I have been checking but need some advice. We are supposed to be heading down to GA on Wednesday and we usually take 81 to 77. Currently does this winter weather watch include I-81? If so we may have to delay one day or take 95. Link to comment Share on other sites More sharing options...

I'm rooting for Ji, Leesburg and Co. to get a little love. Well I'm not. Equality should be emphasized when it comes to winter storms in the greater D.C. are. Equality. Sorry, I'm still bitter about that wretched 2003-04 season. I drove all the way from Upper Marlboro to Gaithersburg in one of those filthy "North & West of town" events just to see the breadth of the shaft; to understand the scale of the outrage. All these years later I still don't think I'm over it. Link to comment Share on other sites More sharing options...

usedtobe Posted December 25, 2012 Share Posted December 25, 2012 The Chill storm looks anything but chill on the 00Z NAM. Really wound up low with tremendous waa and veering with height on the sounding. Gonna rain, gonna rain hard. Look at the 50 knot winds and how they change direction as you ascend on the sounding.

Look at the 50 knot winds and how they change direction as you ascend on the sounding. <snip> Shame it's December with a slight CAD set-up. If we had a 6-7°C/km lapse rate from 925mb then it would be a storm. I'll take gusts to 30kts though. A Coastal Flood Advisory is going to be needed for the Western shore.

swimmatte Posted December 25, 2012 Share Posted December 25, 2012 The real question is, what should we be looking for during this storm that could impact the weekend potential? Link to comment Share on other sites More sharing options...
wxmeddler Posted December 25, 2012 Share Posted December 25, 2012 Prep the ark.. Good point. We're approaching flash flood criteria in some areas if we got a 12hr 2" rainfall. Link to comment Share on other sites More sharing options...
WVclimo Posted December 25, 2012 Share Posted December 25, 2012 00Z GFS still showing significant frozen precip for OKV-MRB-HGR at least through the morning of 12/26. Doesn't get above 32 here until 21Z. Link to comment Share on other sites More sharing options...
WinterWxLuvr Posted December 25, 2012 Author Share Posted December 25, 2012 00Z GFS still showing significant frozen precip for OKV-MRB-HGR at least through the morning of 12/26. Doesn't get above 32 here until 21Z. The GFS has been pretty consistent all day with its effects out here. Seems like a pretty decent event. We will see. Interested to hear what the Euro shows.

Huffwx Posted December 25, 2012 Share Posted December 25, 2012 GFS is interesting down here-- really drives in the sleet/zr for a good bit of the event. Maybe when that SUPER heavy batch comes through we flip, but the first .5 qpf or so is frozen. Link to comment Share on other sites More sharing options...

Yeah but you all get all the fun summer severe weather when we get shafted. I'll be about 30 miles NW of Pittsburgh at 1200' this storm instead of Frederick so I think I'll get to see some good snows for a change! Link to comment Share on other sites More sharing options...

showmethesnow Posted December 25, 2012 Share Posted December 25, 2012 06Z GFS is in good agreement with the 00 run if maybe a touch slower. If correct the OOZ and the 06 suggest the potential for a decent period of frozen slop for north and west of DC and Baltimore before a change over to just plain rain.

showmethesnow Posted December 25, 2012 Share Posted December 25, 2012 The last 4 runs of the SREF have trended slightly south and east with the storm but have shown very little changes with the temps. If the temp profiles are correct they suggest little to no frozen whatsoever except for the mountains. Link to comment Share on other sites More sharing options...

MERRY CHRISTMAS and HAPPY HOLLIDAYS everyone Merry Christmas and Happy Holidays to you and everyone else as well. Haven't really followed the NAM that closely but will be now with it being within 48 hours. You wouldn't know off hand if it's temp profiles have stayed consistent or if they have trended warmer or colder? Link to comment Share on other sites More sharing options...

MERRY CHRISTMAS and HAPPY HOLLIDAYS everyone Every time I look at a model, this low seems just a bit further east and the transfer a bit further south. The NAM has this in NE AL tomorrow morning. I can't tell where the Euro is exactly because of the 24 hr jumps, but it looks coolish. I know location is a big deal with this one, but this may have been written off too quickly. Merry Christmas everyone. Link to comment Share on other sites More sharing options...
