Dense Fog — E Central S.j. Valley, California

2007-12-22 to 2007-12-26 · E Central S.j. Valley, California

Wider weather episode

Behind the series of cold Pacific storms that rolled through California earlier in the month, high pressure slowly built into the Central Valley of California between the 22nd and 26th. As a result of this stable airmass in the region, areas of dense fog developed during the early hours of December 22nd, and lingered over the east side of the San Joaquin Valley into the afternoon. This pattern repeated itself nearly every morning until the 26th of the month. The persistent stable airmass conditions promoted areas of very dense fog where the visibility would fall to nearly zero in small areas.

During the evening of the 24th, a deadly traffic accident occurred, involving a recreational vehicle and a tractor-trailor. One child was killed and two adults were injured during this traffic accident.
