The National Weather Service has expanded the Winter Weather Advisory to now include all of Montgomery and Howard Counties in Maryland and Northern Fauquier, Fairfax and Prince William Counties in Virginia. The Advisory is in effect until 9 p.m. tonight.

Air temperatures have remained at or below freezing in most areas now under the Advisory but in areas south and east of Washington, outside the advised regions, temperatures are a bit warmer. Locations that are now at or just below freezing also have frozen or nearly frozen ground. This is important because sleet or rain or snow that falls on frozen ground or surfaces where temperatures are at or below freezing, will not cause the precipitation to melt. Therefore, a very real hazard could develop for motorists and pedestrians.

Fortunately, the precipitation is moving into our region quickly from the west and will quickly exit to the east during the early evening hours. But during the time the wintry mix is falling, everyone needs to pay attention and slow down on the roads. Anything that looks wet might actually be icy. In areas not under an advisory, there could still be spots where local temperatures could be at or below freezing and that means icy spots could become possible.

Later tonight, as colder air filters into our area, there could be a few flurries. Tomorrow will be a windy and very cold day. In fact, parts of our area may be placed under Wind Advisories for gusts up to 40 mph or higher.

Looking ahead to the weekend, computer model simulations continue to suggest a developing area of low pressure could bring snow or a wintry mix to the entire area by Sunday evening. There at two models that simulate significant snowfall for many parts of our area. So, keep up date online and on air as the weekend approaches.
