A summary of the overnight model suite keeps the Mid-Atlantic in play for an historic storm. The intensity of the low pressure was further emphasized making very high snow totals possible.
Winds will be a huge story as well. Along the coast, gusts as high as 70 mph will be likely, as this low pressure begins to deepen. Within the Baltimore area, gusts will likely average near 50 mph, making visibility a problem and power outages possible.
The snow will have a wet and sloppy start. That's one part of the forecast that hasn't changed either. In fact, a good chunk of southern Maryland will see all rain, which could extend into central Maryland. Therefore, with the latest runs the bulk of the snow appears to fall during Saturday, as an "all day event." Using pure QPF (Quantitative Precipitation Forecast) and an 8 to 1 snow ratio - the Baltimore area would still see a 16" - 20" snowfall given the current track of the storm.
