Now that was taxing...unofficially a barometric low of 969 millibars, or the rough equivalent of a Category 1 Hurricane / strong Tropical Storm. With high wind warnings posted throughout the Mid-Atlantic and Northeast, I wonder if some schools which have not closed or delayed from rain may do so because of wind. Hold a firm grip on that steering wheel.

Accuweather's current call for the early Easter snow event along the Mid-Atlantic. Looks like some bunny ears are going to be frosty AND white...but not because the fur is. Question is... will model trends of the past 24 hours continue, resulting in the DC-Baltimore areas receiving a blanket of white on your newly planted annuals and perennials that I told you several weeks ago not to plant. Given the ever-s0-slight backing off of the North Atlantic Oscillation to near neutral, I'd say there's an outside chance the snow trends a tad bit more north and west. Since this event is occuring in the overnight hours, and the ground has chilled considerably since Wednesday, you might awaken on Saturday to a springlike winter wonderland of snow on the cherry and pear tree blossoms! If that happens here, I'll be sure to post a picture of it. If you catch a good image of spring snow at your house, please consider sending me a copy for posting here: email@example.com. Also, a reminder to our frequent observers, if you begin to experience greater-than-expected frozen precipitation... post your observations in the comments. Thanks everyone and Happy Easter!
