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.

Hello, Kim. The forecast starts with weather balloons taking measurements of the atmosphere, but only a small portion, and only twice a day. Since the network of balloons is small there are usually things that go unseen and some of those things can help develop storms
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!

For weather the primary tools are satellites, radar and computer forecast models that use weather balloon data and many types of other sensors.

Good question, Boyd. When we talk about a high pressure ridge and low pressure trough you can think about those like a hill and valley in the atmosphere. Irma is moving around the edge of the mountain (high) since it can't climb it and the computer forecast models are showing a valley (low) to the north of Florida so it will move to flow toward the valley (downhill). Still some very limited chance for changes, stay tuned.
So sorry about that! Yes, lightning can travel many feet away from the strike point as the energy dissipates. The explosion could have been a pressure build-up from the water boiling rapidly and increasing the pressure, the bolt can reach 50,000 degrees. https://www.weather.gov/safety/lightning-science-ground-currents
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.
