POSSIBLE WINTRY WEATHER

Check out the two model soundings for Fort Smith and Fayetteville at 6:00 AM on Sunday. The numbers on the bottom in yellow are temperatures in Celsius and they are "skewed" to the right up the chart, hence therefore the name "Skew-T chart", which is what the diagrams are typically called.

Of particular note is how close the the red line (temperature) and dashed black line (dew point) are to zero degrees at the bottom of the chart (surface). The temperature profile actually warms aloft and is not below freezing until roughly 10,000 feet, but at the surface all it takes is a shallow layer of air below freezing to create a glaze, especially on bridges and overpasses.

We'll be updating current conditions at 7:00 AM Sunday and will alert you to any travel issues or concerns.
