• Dense Fog in District of Columbia, October 31, 19971 eventA light easterly wind flow developed over the coastal plain during the pre-dawn hours, creating and advecting dense fog into the District and immediate suburbs east and south of town.
• Dense Fog in District of Columbia, January 13, 20061 eventAreas of dense fog occurred early in the morning of January 13 across the region.
• Dense Fog in District of Columbia, February 23, 20061 eventAreas of dense fog occurred during the early morning.
• Dense Fog in District of Columbia, January 12, 20061 eventAreas of dense fog occurred early in the morning of January 12 across the region.
• Dense Fog in District of Columbia, November 29, 20061 eventDense fog occurred on the morning of the 29th across much of the Mid Atlantic.
• Dense Fog in District of Columbia, December 30, 20061 eventDense fog spread across the Washington/Baltimore region early in the morning on December 30. Local observations indicated visibilities restricted to under one-quarter mile at times.
• Dense Fog in District of Columbia, December 14, 20061 eventDense fog formed on the morning of the 14th across the Mid Atlantic.
• Dense Fog in District of Columbia, December 23, 20071 eventAreas of dense fog developed during the early morning hours of December 23rd across Washington DC. Visibilities were often reduced to one quarter mile or less through the morning.
• Dense Fog in District of Columbia, February 27, 20071 eventAreas of dense fog formed during the early morning hours across Washington DC. Visibilities were reduced to less than a quarter mile.
• Dense Fog in District of Columbia, June 7, 20081 eventAreas of dense fog developed during the early morning hours of June 7th across the District of Columbia. Visibilities were reduced to one quarter mile or less.
• Dense Fog in District of Columbia, December 9 to 10, 20121 eventHigh pressure across most of the Northeast and Mid Atlantic led to the development of dense fog across the region. Light winds and saturated low levels aided in fog development.
• Dense Fog in District of Columbia, March 22, 20121 eventHigh pressure off the coast provided an onshore flow across the area. The onshore flow off the Atlantic Ocean resulted in areas of dense fog.
• Dense Fog in District of Columbia, December 2, 20121 eventHigh pressure was moving off the Mid Atlantic coast overnight. Abundant low level moisture and light winds contributed to fog development across the region.
• Dense Fog in District of Columbia, February 17, 20121 eventHigh pressure built overhead causing mainly clear skies and light winds. Radiational cooling combined with higher amounts of low-level moisture to cause areas of dense fog.
• Dense Fog in District of Columbia, January 13, 20131 eventHigh pressure was centered off the Atlantic coast. Southerly flow has transported mild temperatures and moisture northward into the Mid Atlantic Region. Calm winds and low level moisture led to dense fog overnight. This was the second consecutive day of dense fog in the region.
• Dense Fog in District of Columbia, January 13 to 14, 20131 eventHigh pressure was centered off the Atlantic coast. Southerly flow has transported mild temperatures and moisture northward into the Mid Atlantic Region. Calm winds and low level moisture led to dense fog overnight. This was the third consecutive day of dense fog in the region.
• Dense Fog in District of Columbia, January 14 to 15, 20141 eventRidging across the area led to clear and calm conditions and radiational cooling led to temperatures to drop to saturation quickly. Dense fog formed quickly for areas east of the Blue Ridge.
• Dense Fog in District of Columbia, March 2, 20151 eventSoutherly flow ahead of an approaching cold front led to increased low level moisture east of the Blue Ridge. A strong inversion allowed the trapped moisture to develop into areas to widespread dense fog.
• Dense Fog in District of Columbia, October 13, 20161 eventHigh pressure caused light winds, but low-level moisture was trapped underneath the inversion. This resulted in areas of dense fog.
• Dense Fog in District of Columbia, February 24, 20181 eventAn unusually moist air mass and light winds led to areas of dense fog.
• Dense Fog in District of Columbia, December 29, 20181 eventClearing skies, falling temperatures, and abundant low level moisture led to the formation of dense fog.
• Dense Fog in District of Columbia, September 11, 20181 eventA combination of cold air damming, abundant low level moisture, and light winds led to the formation of fog, some of which became dense with visibility less than a quarter of a mile.
• Dense Fog in District of Columbia, May 2, 20191 eventWarm, moist air aloft overrunning cooler surface air combined with lingering low level moisture to produce low clouds and widespread dense fog across portions of the region.
• Dense Fog in District of Columbia, December 13, 20191 eventMoisture underneath a subsidence inversion resulted in areas of dense fog. Visibility was around one-quarter mile.
• Dense Fog in District of Columbia, December 17, 20191 eventMoisture underneath a subsidence inversion resulted in areas of dense fog. Visibility was around one-quarter mile.
