High pressure will dominate during the day on Christmas, bringing quiet weather conditions to the area. By late Christmas evening/Thursday morning, another frontal system will pass to our north. This won't have a huge impact on the tri-state area, with just a chance of some passing flurries. However, north-east West Virginia (including areas like Morgantown) and northern Maryland will likely see better snowfall accumulations. This will have an impact on travel early Thursday morning.
THE NAM FORECAST
7 AM THURS 10 AM THURS
By 7 AM, the NAM hints at the chance of some snow entering northern West Virginia and Maryland. By 10 AM, heavier snowfall (which is indicated by the green shading) is expected to enter Northern West Virginia. Overall, 1-2 inches of snowfall could fall in this area. As of right now, the other forecast models are not as bullish with this chance of snow.
For folks that are heading to Annapolis to see Marshall play in the Military Bowl, this may have an impact on your travel plans. That stretch of 68 that is prone to inclement weather will be very slick on Thursday morning. Therefore, you will want to delay your travel plans and leave Thursday afternoon after the roads will likely be plowed.
On Friday afternoon when the game takes place, conditions are expected to be dry with kick-off temperatures in the mid 40's.
