Light rain is still in the forecast for Tuesday, and it could turn to snow in northern suburbs along the Mason-Dixon Line, according to the National Weather Service.
The Baltimore/Washington forecast office is calling for less than an inch of snow across northern Baltimore County and much of Frederick, Carroll and Harford counties, with 1-2 inches possible in areas closest to the Pennsylvania line. Check the office's snow forecast map for updates.
Precipitation, whether rain or snow, is expected to start after midnight Tuesday and continue on and off through early Tuesday afternoon.
The weather service's hydrometeorological forecasters expect the system to bring mostly light rain to the mid-Atlantic, with light snow along its northern edge from Ohio to New Jersey, according to forecast discussions. No precipitation amounts are expected to be excessive.
Most of Maryland has a less than 10 percent chance of significant snowfall, while to our northeast the chances are between 10 and 40 percent of at least 4 inches of snow, according to the forecasters.
The forecast would do nothing to start the official season snow tally for the year here. Only rain is expected at BWI Marshall Airport, the point of record for Baltimore. November snow has been rare in recent years, with only between a trace and half an inch in three out of the past 10 years.
But of course, there are some weather watchers eyeing a chance for snow. AccuWeather.com's Henry Margusity includes much of Central Maryland in an area that could see snow. Margusity predicts the heaviest snow across southeastern Pennsylvania from York to the Lehigh Valley.
Foot's Forecast predicts falling snowflakes across the major cities of the northeast Interstate 95 corridor, but likely only at the very start or end of the weather event. Only about a quarter of an inch of moisture is expected out of the system, according to Foot's forecasters.
