NWS Sterling not impressed with the weekend event. Late afternoon Discussion excerpt.
A weak ridge of high pressure will pass over the area during the day Saturday, but will quickly retreat offshore Saturday Night as a fast moving shortwave approaches from the Ohio Valley. Dry conditions during the day Saturday will give way to light rain and snow Saturday Night as ascent ahead of the approaching shortwave overspreads the area. The shortwave will be rather compact and progressive, so the duration of the precipitation will only be around six hours at any given spot. As a result, any precipitation will be confined to the Saturday Night time period. Thermal profiles near the surface will be rather marginal for snow. So while a little bit of snow can`t be ruled out anywhere across the forecast area, the best chance for some minor snow accumulations will be to the north and west of I-95.
