January 9 2018

A Dense Fog Advisory is in effect for parts of central Maryland until 8 AM. After the rain stopped, the sky cleared out overnight. This allowed some cooling (for parts of our region) that combined with the west ground helped to saturate the air. Fog may be thick, under 1 mile in places, further hindering the traveling this morning. This fog may also limit the thawing in the early morning hours, but we will all get in to disperse and we all warm up today.

Temperatures:

The ground is frozen, so the air temperatures can be misleading about your ice. Many area schools have at least a 2 hour delay.

The sky cleared overnight. The contrast of the warmer air that attempted to move in over frozen ground and ice covered water has led to a wide range of conditions this morning. Some places are clear nearby to the foggy zones. This may be a demonstration that warm air rising, especially with light wind and clear sky at night. Places like Westminster are now in the mid 30s but BWI is in the lower 20s. Parts of York County range from the teens to upper 20s. Temperatures near Annapolis dropped back below freezing.
