There should then be about an 18-hour window of more settled conditions as transitory ridging builds across the area. However, the break will be short-lived as the next trough moves in on its heels and brings the next round of snow for Saturday. Snow looks to break out late Friday night, more than likely after midnight. With this next system, the heaviest snow at this point looks to fall Saturday morning, with another shot of steadier snow for Saturday night.
