Roads may ice on Tuesday night

The Capital Weather Gang has this warning: On Tuesday night patchy icing is possible over the western and northern suburbs, but the main threat should be at elevations well north and west of Washington.

Meanwhile, the National Weather Service has issued a winter storm watch for Montgomery County from Tuesday evening through Wednesday morning. Initial precipitation may fall as snow before a change over to sleet and freezing rain.

That would make Saturday seem easy for travelers. During my online discussion at noon Monday, drivers complained about the behavior of their fellow road warriors during the Saturday storm.

In both the published and unpublished comments, travelers expressed these concerns:
-- Use of headlights. Many people did not turn them on during the rain and snow.
-- Spacing between vehicles. We had a discussion of allowing extra stopping distance when the road is slippery.
-- Skidding on surfaces at Metrorail stations. One rider was particularly worried about conditions at Archives Station. I noted my concern for all the outdoor platforms during snow and ice storms, because the trains will be stopping at the front of platforms, farther out from the platforms' overhangs.
