A Few Clouds, Very Cold

The arctic front that swept through the area yesterday afternoon is being felt in full force this morning. Temperatures are running around 17 with strong winds and clouds, which speaks volumes to the strength of this air mass. Speaking of strong winds, a tight pressure gradient is creating wind chills just above 0 this morning. Winds should slowly subside as we go through the day, but wind gusts will still consistently remain over 15 mph and make temperatures feel even colder. An approaching shortwave will push through the area today and will produce a few low clouds. At the same time, an active subtropical jet will be screaming over the region and will produce a band of cirrus clouds. Despite the lower and upper level clouds, there will still be a few peeks of sunshine. However, the combination of clouds, a snow pack to our northwest, and the arctic air overwhelmingly support undercutting guidance today. Expect highs to top out around 27 this afternoon. We should be mostly clear tonight, but a few clouds may continue to stick around. With lighter winds and less cloud cover than this morning, temperatures will be likely be near 14 tomorrow morning. If you're heading to the airport to greet the Alabama football team this evening, dress in layers because temperatures will be in the lower 20s for the arrival of the first flight and the upper teens for the second flight.
