the next 10 days will feature a number of things. first will be a warm up.. then around the 1st of jan, the NAO goes negative, with a positive PNA, a greenland block is now on the models, and we have a possible storm on coast around the 2nd and 3rd. the euro as of this writing has a storm on the coast in perfect position for a snow storm, and the gfs has a storm more inland, so we still got 10 days, so alot can happen stay tuned..
well temps have hardly budged today its 1 30 pm and im still at 28.0F so we maybe seeing some sleet snow or ZR at the start of precip tonight, but whatever we get should be rain by tomorrow . looking ahead.. will be a warm up rest of the week. then NAO goes negative and a possible coastal by the jan 2-3,2009 time frame, but … thats 9 days out so im sure alot will need to be re visited by then, as alot will probably change .
Everything looks colder. A very light mix will happen tonight. This will be an event for the valleys and immediate piedmont with some snow and sleet for Maryland and northern virginia with a mix of sleet and freezing rain to end. Precipitation will be light. I see a winter weather advisory being issued by 4pm today for areas along and west of i-95 down to federicksburg and west. Then mountains and immediate piedmont down to roanoke.

looking like a mix to raqin for most, … those of you up,in central pa on north and west of I-81, may see more snow. but near the big cities and south of mason dixon, looks to be a mix to rain.. just not enough cold air gonna be entrenched at low levels or upper levels aloft… of course this can change, but this is how i see it now
A little more of a mix than I thought could occur, but realize that we have a rain storm, a cold one, on the way Saturday night into Sunday. The front end could feature a little snow and sleet, but count on rain.
Mountains of Northern VA and MD – Bit more snow Valleys of Northern VA and MD – Some Ice to deal with
As usual for this area of the country, a clear cut snow forecast is almost impossible! And this will prove no different. I do expect there will be some snow Saturday night for northern regions, but a wintry mix is more likely into Sunday and then maybe just rain. A lot to watch and ponder and this could go either way at this point.
LONG TERM /THURSDAY THROUGH TUESDAY/… KEEP YOUR EYE ON LATE SAT NGT INTO SUN. SIG WINTER EVENT MAY BE UNFOLDING DRG THIS TIME. GFS IS GETTING CONSISTENT IN SHOWING A VERY CLASSIC PTN FOR WINTER WX IN THE METRO AREAS AND POINTS W. IAD FCST MAX TEMP OF 33 IS DOWN A DEG VERSUS YESTERDAYS MEX MAX GUIDANCE FOR SUN AND IT WILL START OFF BELOW FRZG TO START THE EVENT.
850 MB TEMPS START THE DAY AT MINUS 7 IN THE MTNS WITH SFC SYSTEM FCST OVR KY AT 12Z SUNDAY. 2NDRY LOW THEN BEGINS TO FORM ALG THE CAROLINA COAST. AGAIN…STAY TUNED. IF YOU DON`T LIKE WINTER WX…MIGHT BE A GOOD TIME TO CALL YOUR FAVORITE AIRLINE AND GET THAT TICKET TO MIAMI.
looks very interesting this weekend.. stll 4 days to go, stay tuned!!
The mixing was not that impressive overnight. I am again glad I had not hyped this event, though I was so busy i would not have been able to do much this time. The showery weather will persist today, but not as much rain. Cloudy and cool conditions. Tomorrow as the day progresses more rain will start to enter the picture. Again in the northern regions some ice could occur. This looks like more of a Maryland and maybe far northern Virginia.
The bigger threat appears this Saturday night as a low pressure approaches from the south after the cold air has better settled into the region.This is too early to tell, but snow does look to break out Saturday night with a mixing in the southern regions and possible changeover to rain, while north regions change to a mix east of 95. This could be the first significant snow of teh season for a large part of the area!
with all the different types of precip around, its very hard to pinpoint and predict who gets what,.. for example. at 7 pm i was getting heavy sleet and 33 degrees, now at 8 40 pm im getting a sleet rain mix at 32.7 degrees, lol so i think this is more of a now cast, meaning its ever changing, and always has to be updated with what kind of precip we have… regardless on what kind you get tonight, i think by tomorrow afternoon most should see rain. but this weekend could be interesting, but more on that later. be safe on the roads..
Right now this is a route 15 and west threat up into maryland. Sleet and some snow possible. Enough ice for a winter storm warning. The key problem spots will be the elevated surfaces. Route 15 north and west from charlottesville.
Snow and sleet the closer you are to PA. Some areas of western MD could see 2 to 4 inches of slop!
