Weather:Dense fog.

I thought twice about running tonight in the fog as visibility was so poor. I am not sure if running in such conditions is so good for you either. Nevertheless I ran a quick time and feel I have finally recovered from the Scenic Seven.

November is notorious for fog but often at this time of year it is accompanied by mild and wet weather. Often I must admit I interchange the words fog and mist and this is fine, the only difference being the density of the water droplets which are suspended in the air. If the air becomes cooler it can hold less less water vapor and can become super saturated. Some of the water vapor then condenses to form cloud. For the public and the motorist a mist becomes a fog when viability is less than 200 metres.

I would say visibility was down to less than 50 metres tonight and driving wasn’t pleasant.
