Winter weather in Rockville
Montgomery County stretches from the dense Washington, DC border to rural areas upcounty, and the northern part of the county is often colder and snowier than the south. A storm that is mostly rain near the Beltway can be snow and ice farther north.
Large, bus-dependent districts in this area are cautious about ice. If freezing rain appears in the forecast window, watch both the closure and delay odds.
