YES, VIRGINIA, THERE IS A SNOWSTORM.
(Before Thanksgiving? Probably not. First week of December? Most likely.)

For those of you experiencing intermittent display of the links, text and graphics, this is the super basic version you can use to mark your calendars:

Storm #1 potential: For next Tuesday into Thursday, (11/25-27) the European and GFS are hinting at coastal redevelopment of a clipper. Not the best setup for Mid-Atlantic snow, and more probable that interior western sections of Pennsylvania and upstate New York get the snow while the coastal areas get a cold rain. The silver lining is that at the very least the passage of this storm will deliver another round of cold air for Thanksgiving weekend.

Storm #2 indicators: As many of you have already gleaned this snippet from earlier posts, let's get right to the point. If current trends continue, (10 day duration of below-normal temps, the Greenland block, neutral or slightly negative NAO, among other factors) I expect a significant region-wide season-opening multi-precip type storm in the period December 1 - 5. Too early to say if this will be all snow, but I would suspect most of the Mid-Atlantic will see a variety of snow, sleet and possibly even freezing rain depending on surface temperatures when the storm takes shape.

The atmospheric indicators of these two potential events will be closely followed, so I encourage your reactions and speculation as we look to nail down the details over the 10 days. Analysis of the indicators and more in depth discussion will be added to posts below.
