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.
Tornado debris signature. Radar can tell the difference between rain and hail and other “targets”. When a tornado starts lifting things in the air the radar can show that, often called a debris ball. It is helpful because farther away from the radar dish, as the earth curves away from the beam, what we see are radar targets above the surface as opposed the the actual tornado. The TDS gives more confidence that the rotation is actually on the ground. Thanks! https://en.m.wikipedia.org/wiki/Tornado_debris_signature
Share Answer: 
Likely not. A severe thunderstorm warning is triggered by one inch hail and/or 58 mph winds. Different process. A thunderstorm is more of a local convective event and strong winds in a blizzard are a larger scale pressure gradient event. Great question!

Yup. Some do. ;)

Tough call for me not knowing specific examples and a location, Mark. I will say that the temperature can only fall to the dewpoint, so if the moisture content of the air, dewpoint, stays around 32 that could account for what you are seeing. You can find the current dewpoint by looking for your city on weather.gov. Hope that helps.

Do you ever operate on guys who get their jaws busted in a fight?
Rain on its own doesn’t cause choppy seas, Ron. The wind creates the chop and the speed of the wind is determined by the difference in pressure between the low pressure storm and surrounding high pressure. The atmosphere doesn’t like to be out of balance so the greater the difference in pressure the faster the air moves to find balance. Thanks.

Great question. The answer is somewhat personal choice. A severe thunderstorm is defined by 1 inch hail and/or winds of 58 mph or greater. Those things can certainly break windows and cause damage. Absolutely be inside. We try our best to provide substantive warnings and information but if you ever feel threatened by the weather by all means don’t wait for us and take cover!

Great question, Marv! The exact location would have a lot to do with it but, in general, cold air is heavier than warm air. In the winter, especially at night, the cold air sinks into the valleys and pools up. At the beach, when the sun is out, the land warms faster than the water and the air above the land rises. Since the air needs to be replaced the cooler air moves in from over the water on the sea breeze. Hope that helps. Thanks!
