...FIRST WIDESPREAD WINTER EVENT OF THE SEASON... .Precipitation is expected to overspread the area after midnight tonight from southwest to northeast. While precipitation is likely to start as snow areawide, it is expected to mix with and change to sleet and freezing rain for most of the area. Locations along and south of US-50/I-66 likely end the event as rain as temperatures warm through the morning. Areas along the Mason-Dixon Line are most likely to remain all snow through the event, but that remains uncertain given exact low track. The Tuesday morning commute could be impacted for all areas in the Winter Weather Advisory. Updates to the forecast are likely, so please remain weather aware for the first widespread winter event of the season. * WHAT...Mixed precipitation expected. Total snow and sleet accumulations of 1 to 2 inches, with locally higher amounts upwards of 4 inches possible near the Mason-Dixon Line and higher elevations such as Parr's Ridge. Ice accumulations up to one tenth of an inch. * WHERE...Portions of north central and northern Maryland and eastern West Virginia. * WHEN...From 3 AM to 1 PM EST Tuesday. * IMPACTS...Plan on slippery road conditions. The hazardous conditions could impact the Tuesday morning commute. * ADDITIONAL DETAILS...Precipitation is expected to overspread the area after midnight tonight. Precipitation is expected to start as snow before mixing with sleet and freezing rain. Should precipitation stay all snow or snow for a longer period of time, locally higher snowfall amounts would be possible.
