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.
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.
Yup. Some do. ;)
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!
Hi, Manning. Yup, saw it. Feel bad for him since that video will be attached to him for a long time. Often times it is a hard choice to break into programming. We all understand the interruption. Severe weather can be a high stress environment. It is particularly frustrating when someone makes a ridiculous comment like, “you just want to hear yourself talk.” Happens to me just about every event. Gotta take a deep breath and move forward. For every snotty response I usually get “thanks for keeping us informed,” tenfold. 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
I did see that some months ago when it happened. Tough situation. Can’t say I have a comment.
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!
