Cold Air Invades for Thanksgiving Week
There are two different cold fronts coming through Kentuckiana this week bringing bitterly cold air. The first one will come through Tuesday night, which means Wednesday morning will be very cold. That's a travel day for many people being the day before a holiday, so let's break down what you will see.
Temperatures Wednesday morning will be in the upper 20s, but notice the direction the wind is coming from. It's coming out of the north/northwest in the image below. That means the wind chill values will be much lower than temperatures.
Wind chills, according to the North American Model, will be in the teens across Kentuckiana. The good news here: even with wind chills that cold, it will still take more than 30 minutes for frostbite to set in if you're exposed to this bitterly cold air. Even as cold as it will be, this is not considered dangerous unless you are outside without a coat/gloves/hat, etc. for an extended period of time.
Temperatures on Thanksgiving morning will be similar, but wind chills won't be quite as low. Notice the wind pattern in the image below. It's hard to pick one out near Louisville because there will be a High Pressure very near us Thursday and Friday. Thanksgiving and Black Friday will start cold, but not with wind chills in the teens.
If you're not spending the holiday in Louisvile, here's how you can figure out the wind chill for where you are traveling. This chart is from NOAA.
