Amazing morning of fog on the Front Range.

Although the freezing precipitation event didn't amount to much, the freezing condensation event this morning was truly impressive. Boulder (and several other cities) were locked in a freezing valley fog for several hours. Visibility was very poor and most of the landscape was covered with a thin layer of frost. As the fog cleared, I witnessed fog "devils" rising over the Front Range as stronger upper level winds plunged down toward the 700mb level. As the fog deck lifted above my head, I could see wave clouds (associated with high wind events) illuminated by the rising sun. Quickly reviewing my photos, I can see that I've pulled off the best fog shots I've ever captured (one of these shots will appear on perilousplanet.com in a couple weeks - above shot is just general documentation). Meteorologically, it was an incredible day.

Although fog is less glamorous than some hazards (such as a tornado), it is still a significant hazard and has claimed the lives of thousands of people. Although the National Weather Service predicted this fog and issued a Hazardous Weather Outlook that described current conditions of less than 1/4 of a mile, they failed to issue a dense fog advisory. At 6000 feet near the city limits of Boulder, visibility was less than 500 feet on county roads for several hours. I'm going to contact NWS to request clarification of their reasons for not issuing an advisory for this event, and strongly encourage them to review their policies pertaining to the issuance of advisories.
