Thursday Snow Threat Increases, Weekend Threat Decreases

RPM snowfall forecast ending 7pm Thursday 16 Dec. 2010

U.S. model (GFS) takes weekend storm farther east

Another potential snow producer approaches Tuesday 21 Dec 2010

Late evening computer models have increased the snow threat for Maryland on Thursday to 70%.  Our in-house 12km RPM model is producing 2-4″ of snow across southern Maryland by 7pm Thursday evening, with 1-2″ near the PA border.  In between these two extremes, the model indicates 1-3″ for the Baltimore Metro area  by 7pm.  Additional snowfall may be possible in left over snow showers Thursday night.

Meanwhile, the weekend snow threat is diminishing.  The 0z GFS model has moved the surface low farther east, looking more like the Wednesday morning European model.  If this trend holds for another couple model runs, we might be watching a decent storm pass us by off the coast Sunday and have to start turning our attention to the next snow threat rolling this way next Tuesday, December 21st.  Just in time for the winter solstice!
