I've been a broadcast meteorologist on television since the early 1990's. Happy to answer any questions about the weather or local TV news. Yes, I often wear sneakers on set just out of view of the camera.
Thanks for the note. That really is a "climatology" issue as opposed to "meteorology" which is really my area. A climatologist would be better equipped to answer your questions. Thanks.

Different computer forecast models will give guidance on the amount of liquid. Snow totals are variable based largely on the temperature profile of the atmosphere above the ground. A general rule is about 9-10 inches of snow per inch of liquid, variable based on several factors, including forecaster experience in the area. Great question.

Great question. All cloud drops form on a speck of something called a condensation nuclei, dust, smoke, sea salt, etc. The idea with seeding is to introduce these particles, often silver iodide, to encourage the water vapor in the air to condense into a cloud droplet and then merge with other drops to form rain. A lot of question as to if it works but there is enough evidence that people keep trying. Thanks!

How often would you find yourself in real danger?
For weather the primary tools are satellites, radar and computer forecast models that use weather balloon data and many types of other sensors.

Thanks, Marty. Not really as you've described. I do know there is some evidence, and research, that shows that the heat island effect of cities can affect local weather. I remember one study showing the increased heat radiation from Atlanta on a hot summer day has been shown to create small thunderstorms just downstream. Buildings can certainly affect wind flow and some coastal buildings have been seen to create some small cloud or fog formation as air moves past them. Good question.

Great question, Judith. I must say I'm not really familiar with SF climatology. In general air pressure changes with the movement of weather systems so a short move might not have a big effect. But local topography could come into play. I'll suggest your local National Weather Service office would find your question interesting. Good luck!
