Sunny But Cold

A weak cold front pushed through the area overnight and has brought even colder and drier air. Temperatures are barely above freezing with dew points in the 20s this morning. With such dry air in place, it might not be a bad idea to carry the Chap Stik with you today. Today will be the coldest day of the season despite plentiful sunshine. We'll struggle to make it out of the 40s, and I think we only top out around 49 this afternoon. When the sun sets, we'll really experience the cold air tonight as an ideal radiational cooling setup will be in place. I'm undercutting the guidance and NWS given light winds, clear skies, and very dry air, which should allow us to bottom out near 24 overnight. However, if the wind is blowing at all, we'll likely be 2-3 degrees warmer. Be sure to bring your pets inside tonight! The future upper air pattern suggests cooler and drier than normal weather for the next 7 days. Our next chance of rain won't come until at least Tuesday of next week.
