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.
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!

I did see that some months ago when it happened. Tough situation. Can’t say I have a comment.

You might get a better answer from a hydrologist, Glen. Water does continue to empty into the ocean, or a lake. The overflow occurs when the water running into the river is greater than what is flowing out. The incoming water can come from creeks and streams and heavy rain. Thanks!

Not sure I have a clear answer to that one. Outside of any of the many influences of things like wind, clouds, warm and cold fronts, the heating process begins as soon as the sun rises and cooling begins once it sets and starts again each day. Many factors such as the amount of moisture in the air, even dust or smog, even temperature, affect the heating and cooling rate. There are math formulas that address ideal situations but college meteorology class was a long time ago!

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!

Interesting question with a possible complicated answer. The easiest data point to look at is probably dewpoint, which is the amount of water vapor in the air. Obviously it is cooler at night because there is no incoming sunlight. Overnight the heat from the day radiates out to space and the air cools. The temperature will never fall below the dewpoint and when that number is reached the air is considered saturated. So the dewpoints are likely higher in Kansas as opposed to Colorado. Moisture travels northward from the Gulf easier across the plains as opposed to the higher elevations in the mountains. So check the dewpoint. Thanks!

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
