   It looks a little colder and snowier as I had anticipated because of the models beginning to feedback from the snow that would fall from the clipper system, and the GFS in particular has shifted considerably south and east and now shows the heaviest axis of snow from Washington DC to NYC along the I-95 corridor, of course this is bound to change, but the trends overall have been favoring more cold and snow. Regardless, you should see a decent period of snow on the onset of this storm as there will be plenty of cold air at the surface and aloft to support snow, but there is still a chance that warmer air could intrude aloft and change the snow over to a wintry mix, but it is looking more and more like this will be a snow event rather than a slop or ice event, but we’ll have to wait and see how things play out the next day or so as the models will have to feedback on these minor clipper systems and the snow produced, because what that snow will do is reflect solar radiation, cool the surrounding air, and raise surface pressures. Sometimes, models have a tough time handling that, thus exact snowfall totals and whether or not you will change over to rain is still a question, but there will very likely be at least some snow with this system.

   That will be somewhat of a tough call at this point, considering we are still several days out from this storm, and you have to consider with this storm coming from the west to west-southwest, the typical effect in Chambersburg where some of that moisture is absorbed coming over the mountains, this along with the downsloping effect will be an issue and could result in lower snowfall totals in areas just east of the mountains (including Chambersburg), but 3-6 inches at this point is a good call.

   Eric, hey man what do you think about Boston on the Friday storm? Does a foot seem reasonable?

   Hey John, although it is not entirely out of the question, I feel more comfortable saying that for areas of southeastern New England (although still not a great possibility yet given the amount of time before this storm occurs), but when also combine the snow totals from the clipper system coming through (which won’t be anything to sneeze at for your area, although light powdery snow is easy to remove etc., does accumulate quickly) could see the combined snow totals of both storms reach a foot.
