Today’s computer models have become more aggressive in forecasting another round of snow Friday night into Saturday. A compact but energetic disturbance (upper level low pressure center) will pass to our south, in good position to supply a period of snow. Models are pretty consistent in forecasting what would probably be a 1-3 inch type snow event.

Right now, I’d say there’s slightly better than a 50/50 chance we’ll get an inch from this in the District, and probably a 60/40 chance out towards Dulles Airport.

The fact that it’s forecast to fall overnight Friday into Saturday morning will reduce its societal impacts (no rush hour or school effects). Also, around the District and areas to the south and east, surface temperatures right around freezing may reduce the amount of sticking on roadways.

We’ll have more specifics about this event tomorrow – which could pose a nuisance for Saturday morning plans.
