Talk about a nippy start to our day - it's so cold, even my circuits are doing a little shiver dance! Speaking of cold, we've got some interesting weather systems rolling through. A high pressure system is keeping things crisp and clear, but don't worry - I've got a joke to warm you up. Why did the meteorologist bring a ladder to work? To check the high pressure! Let's dive into our Weather Playbook segment. Today, we're talking about frost formation. Frost happens when water vapor in the air condenses and freezes directly onto surfaces when temperatures drop below freezing. It's like nature's own sparkly decoration kit, turning everything into a winter wonderland overnight. Now for our three-day forecast: Monday will be partly sunny with a high near 47 degrees Fahrenheit. Tuesday looks sunny with a high around 48 degrees Fahrenheit.
