31.3F at 5am here in Clarksburg. We've been below freezing the entire time and it will look like a winter wonderland when the sun comes up. Ground was frozen at onset (high was 31.9F yesterday) and temp dropped from 29.0 to 27.9 at onset, matching the DP. The rise to 31 has been slooooooow with almost no wind whatsoever even during the heavier showers.

More than 0.1" inches ice accreation but less than 0.2". 31.6°F back home, looks like the freezing line is in Gaithersburg according to my car thermometer.

Icey winter wonderland here ..probably up to 1/4" on some trees. All surfaces covered except main road. Temp just above freezing.Schools delayed. Maybe tracking snow showers tonight. 7th frozen observation of the this young winter season so far. Most wintery start I can ever remember this early. Hope it continues.

About the same here.
