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.
Hi, Ginger. I’m unfamiliar with “pron”. We’re taught to think of air in parcels sometimes because it helps to visualize the atmosphere and how it will react to influences. Like a hot air balloon will rise as long as the inside air is warmer than the surrounding air. So a parcel of dry air can have specific effects, as can a parcel of moist air. If you’re still curious you could contact your local NWS office and weather.gov. The person you listened to was likely a forensic meteorologist, you could do a web search. Thanks!
All the time, Danny. Most folks seem to appreciate that we are trying to keep them informed and in many cases safe. But some people do get pretty grumpy when we interrupt their TV shows. Thanks.
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!

For the most part the sun doesn't directly heat the air. It heats the ground which then reradiates that energy in the form of longer wave radiation which heats the air. The strongest heating occurs midday when the sun is highest in the sky. At that point the sunlight is traveling through the least amount of atmosphere as opposed to earlier or later in the day. So there is a short lag between maximum sun angle and the time is takes the air to heat up. Thanks, Tommy. Hope that makes sense.
Often times changes like that come because the outlook on a given day is highly dependent on what happens during the day or days before. A small variation in the specific way storms develop and behave can mean a big change in the development hours later or the next day. Another explanation includes the somewhat large distance between twice daily weather balloons. A lot of things can go undetected between them. Thanks, DJ!
Hi, Craig. Europe weather and climate is pretty far out of my area of expertise. You might have better luck with the UK Met Office. Good luck. https://www.metoffice.gov.uk/
