An Arctic front is about to deliver a burst of snow, extreme winds and rapidly falling temperatures to Washington, DC, and Baltimore, Maryland.
Winds gusts of up to 50 mph will accompany the snow over the next couple of hours.

There won't be much snow: Only about an inch of accumulations are expected. But combination of the snowfall and gusty winds will create greatly reduced visibility and will likely cause travel trouble on the roads and at the DC airports.
And a flash freeze is possible: Temperatures behind the front will quickly drop by 10 degrees in less than 30 minutes. This will cause a flash freeze of any untreated wet roads, sidewalks and parking lots.
Temperatures will continue to fall to around 20 degrees by 6 p.m. ET.
