1:30 PM | Potential grows for frozen precipitation and even accumulating snow Friday night/early Saturday
A cold front that extends from a fast-moving low pressure system will pass through tonight and it should generate some snow shower activity here during the evening hours that could leave a coating of snow in parts of the region. The next system to affect us on Friday night and Saturday will have more moisture to work with and recent model trends for a colder scenario have continued today. It appears as if snow will break out tomorrow night, perhaps just before midnight, and continue for awhile before any mixing or changeover occurs. As a result, there is the potential for snow accumulations in the 1-2 inch range north and west of the District before any mixing or changeover actually occurs and there can be any icy buildup for awhile after the snow ends. A strong, cold high pressure system to our north will be the key player in this early weekend event as it should lock in the cold air which will be reluctant to give up its ground at the time the moisture arrives. Stay tuned.
